Four reasons to plant certified wheat seed

SyngentaAgronomy — Mon, 04 Jan 2016 14:32:23 +0000

It’s not unusual for farmers to purchase certified seed (which has passed rigorous inspection and testing by government agencies) for planting, then save harvested seed for two or more years before buying fresh seed. The challenge with this method is that the further removed saved seed is from the original certified seed variety, the greater the risks of:

Varietal impurity
Poor seed germination
Diseased seed
Volunteer crops and weeds

The initial cost of saving seed is lower than certified seed, but doing so may actually end up leading to a need to purchase more seed and/or apply more crop protection products if the saved seed doesn’t perform as well as hoped. Research has shown that certified seed varieties consistently outperform saved seed in yield, quality and test weight. By planting certified seed varieties such as AgriPro® brand wheat from Syngenta helps ensure:

Genetic purity
Smoother plantability
Seedling vigor
Improved germination and emergence

Think stalk quality when selecting ’16 corn hybrids

SyngentaAgronomy — Wed, 06 Jan 2016 14:42:36 +0000

Stalk integrity and standability were hot topics during the 2015 harvest, unfortunately for the wrong reasons in many places. To have a better experience in 2016, there are some steps that can be taken right away.

Hybrid Selection: Hybrid selection is critical to helping seeds start strong. Choosing the right hybrid for the right condition can be the difference between good yields and great yields. This is especially true to help prevent deteriorated stalk health and to ensure crops reach their maximum potential. Check stalk strength ratings for hybrids using tools like the Golden Harvest® Corn product finder, and be on the lookout for hybrids with additional protection against below-ground insects like corn rootworm.
Crop Protection: Syngenta agronomists observed that crops where fungicides were used performed better under pressure from diseases like northern corn leaf blight and experienced fewer standability issues. When choosing a fungicide package for next year, it is important to keep in mind that this added protection can help stalk health for their fields.

Naked soybean seeds are risky proposition

SyngentaAgronomy — Fri, 08 Jan 2016 15:11:10 +0000

When planting, you never know exactly which circumstances and pests your soybeans will encounter during the season – but you do know that there will inevitably be something. Protecting your seed from the start pays off with higher yield potential, fewer replants and lower chances of intensive scouting and last-minute corrective applications. The Ohio State University Extension and the University of Kentucky Extension explain that you can greatly benefit from applying a seed treatment in the following situations:

Many soilborne pathogens require moisture, and poorly drained or flooded fields provide an environment conducive to disease.
Low seeding rates are used. Each and every seed becomes more important.
Spring was cool or you are planting early. Under these conditions, seedlings take longer to emerge, giving the soilborne pathogens more time to feed.
Your field has a history of Phytophthora presence, soybean cyst nematode (SCN) or another disease/pest.

Clariva® Complete Beans nematicide/insecticide/fungicide, a combination of separately registered products, provides a revolutionary nematicide with direct, lethal activity against SCN – adding effective, season-long SCN protection to the market-leading, broad spectrum pest protection of CruiserMaxx® Beans with Vibrance® insecticide/fungicide, a combination of separately registered products.

What you can’t see can hurt your sugarbeet yields

SyngentaAgronomy — Mon, 11 Jan 2016 20:34:37 +0000

When we think about damage to our crops, we often focus on what we can see - those insects, weeds and diseases visibly hurting our yields. What we sometimes forget is that there can also be threats quietly eating away at our profits out of sight below the surface. One such “invisible” pest afflicting sugarbeet growers is the sugarbeet cyst nematode (BCN). The number of fields with confirmed BCN presence has grown drastically over the last 30 years, and the pest has become increasingly difficult to manage. These microscopic parasitic can cause extensive damage such as reduced stand, stunted beet growth and decreased root efficiency, all of which can lead to yield losses up to 80 percent. The battle against BCN is fought with proactive management practices beginning at seed selection time. The Syngenta sugarbeet portfolio has several nematode-tolerant Hilleshög® brand sugarbeet varieties. These varieties are offered in areas where nematodes pose a significant threat to crops. Please check with your local Hilleshög Sales Agent or co-op agronomist for availability. To further enhance protection against BCN, Syngenta also offers Clariva® pn seed treatment nematicide. When used in conjunction with CruiserMaxx® Sugarbeets insecticide/fungicide, combination of separately registered products, Clariva pn seed treatment provides triple protection against seedling diseases, insects and BCN through its unique mode of action, maximizing yield and profit potential. In addition to choosing the best-suited variety and seed treatment for your field, be sure you are soil testing and scouting regularly throughout the season to monitor for signs of BCN damage. It’s also important to speak with local seed agents and agronomists who can provide recommendations about timely crop management. In doing so, you’ll help ensure your crop gets off to a healthy start and remains competitive throughout the season, ultimately enabling you to maximize your return on investment.

The spinach disease you can’t afford to ignore

SyngentaAgronomy — Wed, 13 Jan 2016 23:05:46 +0000

Downy mildew is the No.1 disease in spinach production almost everywhere spinach is grown. With new races of downy mildew popping up in spinach over the last several years, you probably had to use many tools to stay a step ahead of the devastating disease. Downy mildew spreads rapidly, so it’s important to recognize the symptoms before it’s too late and be proactive in your management practices. Cultural controls such as reducing leaf wetness can be a key preventive approach because the pathogen thrives in wet conditions. Additionally, using a fungicide like Orondis® Ultra, currently sold as a multi-pack product combining Orondis Ultra A and Orondis Ultra B, offers excellent control of downy mildew in spinach. Orondis Ultra fungicide is currently approved for use in 43 states, with approvals pending in California and others. It combines two products, Orondis and Revus® fungicides, into a powerful one-two punch that knocks out downy mildew in spinach for built-in resistance management and protection of the crop when it is most actively growing. It offers excellent protectant and increased residual disease control to ultimately help you maximize marketable yields. To learn whether Orondis Ultra is approved for use in your area, visit this page. For more information, talk to your local Syngenta representative.

Don’t let potatoes fall victim to storage diseases

SyngentaAgronomy — Thu, 14 Jan 2016 22:42:11 +0000

Based on estimates from United States Department of Agriculture, 7.5 percent of potato loss occurs during storage. While normal transpiration and respiration cause some potato weight loss, the more serious cause is often storage diseases. Storage disease cannot be cured, but the spread of pathogens can be limited so that healthy potatoes are protected. For the best possible yield and quality, you should utilize an integrated, full-season approach from seed through storage. The yield and quality that result from good growing practices must also be protected with good storage practices. Stadium® fungicide combines three active ingredients – fludioxonil, azoxystrobin and difenoconazole – to provide targeted control of potato diseases, including silver scurf and Fusarium dry rot. Stadium remains active for months of storage, providing long-lasting protection with only one application. Applicators can take several proactive steps to get the best possible results from Stadium. Remove as much dirt and debris as possible from potatoes to ensure complete and uniform coverage prior to treatment. Stadium should be applied immediately after harvest. Applications of Stadium should be made as a dilute spray of one fluid ounce of product in an appropriate amount of water carrier to cover 2,000 pounds of tubers. The spray should be applied to potatoes in a single layer as they are tumbling from belt to belt or onto the piler. Once treated, the tubers should appear slightly moist but not dripping or shiny. Growers should be aware that MRLs in export markets outside of North America are lower than those in the United States and may not be high enough to cover residue on all potato products. Prior to Stadium application, growers are advised to check with their potato buyer regarding Stadium use.

Protect soybean root systems from sudden death syndrome

SyngentaAgronomy — Tue, 19 Jan 2016 22:04:39 +0000

Sudden death syndrome (SDS) is a soybean disease that has been detected in all major soybean-producing states and depending on the conditions, can cause significant damage. SDS is caused by the fungal pathogen Fusarium virguliforme, which infects seedlings as early as one week after emergence, when root systems are vulnerable. SDS is often identified in fields infested with soybean cyst nematode (SCN). SCN feed on the root systems, which make soybean plants more susceptible to diseases like SDS. Unfortunately, there are no in-season management tools for either SDS or SCN because the fungal infection is restricted to root systems and fungicides typically do not move downward in the plant to reach the site of infection. The key to preserving yields is to start strong and protect young root systems. The addition of Clariva® Complete Beans with Mertect® 340-F seed treatment, a combination of separately registered products, to the Syngenta seed treatment portfolio marks a milestone in SDS management. Clariva Complete Beans offers season-long SCN protection as well as reduced damage from SCN-related diseases, such as SDS. Adding Mertect 340-F with direct activity on SDS provides a double mode of action to help manage SDS. Before the recent introduction of seed-applied treatments, genetic resistance provided the primary management option to protect against SDS. Clariva Complete Beans and Mertect 340-F complement SDS-resistant NK® Soybean varieties and add an additional layer of protection to your investment, ultimately helping you grow more soybeans.

You won’t see gummy stem blight coming, and it’ll hurt

SyngentaAgronomy — Thu, 21 Jan 2016 20:52:38 +0000

Gummy stem blight is a highly destructive, foliar fungal disease that can cause yield losses of more than 50 percent in watermelon crops. With warm, wet conditions in 2015, gummy stem blight spread to a wider region than ever before. Unlike other diseases for which impact can be predicted, gummy stem blight is a major problem because it can occur without warning. The fungal disease causes lesions on leaves and causes stems to exude a gummy material. The impact of gummy stem blight can be minimized if addressed in a timely manner that includes fungicide applications. For control of gummy stem blight in watermelon crops, consider Inspire Super® fungicide. Combining a trusted chemistry with the active ingredient cyprodinil, Inspire Super offers effective disease control with excellent rainfastness and flexible application options, easily fitting into existing management programs for optimal yield and quality. To learn more, contact your local Syngenta representative. Inspire Super applications on day 16 and day 23: inoculated with Gummy Stem Blight on day 18 and kept in a high humidity chamber for 48 hours.

Can winter weeds harbor SCN?

SyngentaAgronomy — Tue, 26 Jan 2016 21:26:27 +0000

As the most detrimental pest to soybeans in the U.S., soybean cyst nematode (SCN) often destroys 30 percent of yields with no obvious aboveground symptoms, according to the University of Illinois Extension. To manage SCN, Syngenta recommends rotating crops, planting SCN-resistant varieties, using a seed-applied nematicide and soil sampling after every second soybean crop. It’s also extremely important to keep fields clean from winter weeds, such as henbit and purple deadnettle, which act as alternative hosts to SCN during the months between harvest and planting. These precautions help maintain the protection offered by genetic SCN-resistance sources. Syngenta encourages you to develop a proactive management plan to protect your yields from SCN. Clariva^®Complete Beans seed treatment, a combination of separately registered products, contains a nematicide, an insecticide and three fungicides, providing crops with triple pest protection during the critical early-growth stages. The nematicide component of Clariva Complete Beans contains a revolutionary nematicide with direct, lethal activity against SCN. A proactive SCN management program that includes a seed treatment like Clariva Complete Beans is essential to protecting your soybeans from increased yield loss and increasing your return on investment. Additionally, a burndown application of Gramoxone® SL 2.0 herbicide will help your soybeans start clean and eliminate early-season weed competition. Planning for a soybean herbicide application should always include using a broad-spectrum pre-emerge herbicide to protect against weed competition and improve control of tough weeds, helping you grow more soybeans. ©2016 Syngenta Important: Always read and follow label instructions.

How will you manage PPO-resistant pigweed in 2016?

SyngentaAgronomy — Wed, 27 Jan 2016 21:38:43 +0000

TENNESSEE: As 2016 begins, growers here continue to ask about controlling PPO-resistant pigweed, which was confirmed in 2015 in Tennessee and Arkansas. To avoid a pigweed forest in your fields, we recommend a two-pass herbicide program using multiple effective modes of action. Proper timing has always been important for the success of any herbicide program. The application of the second residual herbicide must be applied prior to weed emergence after the initial application. PPO-resistant pigweed has made this overlapping of residuals even more crucial to the success of these programs. We saw great results with this approach using our latest herbicides at our Grow More Experience Site in Cordova, TN. As you can see in the photos below taken Aug. 26, Acuron® herbicide provides exceptional weed control in corn. On the left is the untreated plot, while on the right, Acuron and AAtrex® herbicides were applied pre-emergence followed by Halex® GT herbicide and AAtrex. Corn was planted and pre-emergence herbicides were applied on April 23 (Acuron at 1.25 qt/A and AAtrex at 1.5 pt/A) with post-emergence herbicides applied May 28 (Halex GT at 3.6 pts/A and AAtrex at 1 qt/A). In soybeans, BroadAxe® XC herbicide is another great option for controlling a broad spectrum of weeds, including pigweed, as displayed below in the plot planted May 7. Again, untreated is on the left. BroadAxe XC was applied pre-emergence on May 7 at 25 oz/A followed by a post-emergence application on June 9 of Prefix® (1 qt/A) and Touchdown Total® (24 oz/A) herbicides. Photos were taken June 23. To control PPO-resistant pigweeds in cotton, growers can turn to Sequence® and/or Reflex® herbicides. Both herbicides provide effective weed control and long-lasting residual activity for fields that stay cleaner longer.

Last year’s key takeaways help Ohio farmers prepare for 2016

SyngentaAgronomy — Thu, 28 Jan 2016 21:22:10 +0000

Winter is a good time to reflect on the previous season in order to prepare for the upcoming one. Our Marysville, Ohio, Grow More Experience site improved our understanding of how various Syngenta products can help growers in the area improve their crops’ productivity. We witnessed dramatic in-field visuals during each part of the season, such as the effects of using Syngenta products versus competitor products, and the benefits of tailored seed selection. Below are several insights we gathered that can help you plan for this upcoming growing season. Early-season It didn’t take long for us to notice that soybean cyst nematode (SCN) pressure jeopardized the soybean crop at the beginning of the growing season. Clariva® Complete Beans, a combination of separately registered products, showed a superior advantage on crop safety to the soybeans compared to the competitor’s product. The seed treatment offered the protection necessary to help soybeans start strong and evade the root-feeding nematode early on. Additionally, we saw significant damage in the untreated plot compared to Clariva Complete Beans. While we couldn’t see a re-infestation of SCN with the naked eye, it was definitely visible economically at the end of the year. The Clariva Complete Beans-treated plots, however, saw long-lasting protection from SCN. Mid-season Weed pressure picked up due to an extended period of rain in late spring/early summer. Tough broadleaf weeds including giant ragweed and morningglory became problematic in our area. In corn, we saw our herbicides, such as Acuron® herbicide, applied at full rates and our planned two-pass herbicide programs deliver better weed control than the competition. Late-season Closer to harvest time for corn, the strongest visual we noticed was in the corn ear-feeding plot. After the silking stage, corn at our site experienced heavy larval infestations. Hybrids with the Agrisure Viptera® trait saw the most protection from the high insect pressure, again showing how this trait is a game changer in the marketplace. Its outstanding control of above-ground insects helps to significantly reduce mycotoxin and aflatoxin contamination. To maximize yields, we recommend that growers visit their local site throughout the growing season to see how Syngenta products and technologies can benefit their fields at each stage.

Before you plant, plan to protect your potatoes

SyngentaAgronomy — Fri, 29 Jan 2016 19:20:08 +0000

With potato planting approaching rapidly, it’s important to set a solid foundation to protect your investment from disease and insect pests. You can improve your potato crop stand, vigor and yield potential all before planting with a seed treatment, an excellent way to protect the crop right from the start and well into the season. For the best early-season protection, a liquid seed treatment is your best bet. Liquid seed treatments provide accurate coverage and a more uniform distribution. They are easy to calibrate and thoroughly cover the seed piece, offering strong protection against insects and diseases. By working on cut, precut and uncut seed, liquid seed treatments offer something for everyone, especially since they also fit a wide range of treating and planting operations. Additionally, liquid seed treatments save time and money since very little product is lost during application. Syngenta offers excellent activity against a broad spectrum of insects and diseases with CruiserMaxx^® Potato Extreme seed treatment insecticide/fungicide. With the powerful combination of three liquid active ingredients and a drying agent, CruiserMaxx Potato Extreme provides uniform coverage along with precise application for maximum seed protection against insects and diseases. For additional protection against tough-to-control early-season diseases, consider an in-furrow application of Elatus® fungicide. Elatus delivers enhanced, early-season control of soilborne diseases, and provides excellent control of Rhizoctonia resulting in improved emergence, more uniform crop stand, enhanced crop health and optimized distribution of tuber size. Elatus also contains built in resistance management, with the only in-furrow technology that contains a proven strobilurin and third generation SDHI fungicide. Diseases and insects can appear early, and without warning, so be on guard and get an early-season management plan in place before they become a problem.

Citrus Greening and ASP Found in Florida Panhandle

SyngentaAgronomy — Mon, 01 May 2017 22:08:56 +0000

FLORIDA – The Huanglongbing (HLB) disease, also known as Yellow Shoot or Citrus Greening, is a fast-spreading disease on the rise in the U.S. According to a report from the University of Florida Extension, there are now cases of the disease on citrus trees in the Panhandle of FL. The carrier of the disease, the Asian citrus psyllid (ACP), has also been reported in the area. And where you see ACP, you’ll likely find HLB. The first sign of infection is the yellowing and thickening of leaves and the corky appearance of veins. The fruit will also appear small, discolored and uneven in growth; the taste may be extra sour. When trees are severely infected, sometimes the only course of action is to dig up the tree altogether. While the majority of mature, fruit bearing trees in FL groves are assumed infected, there are still opportunities to help prevent disease proliferation. In the case of young, new plantings that are not yet infected, curtailing psyllid populations is priority number one. The adult insect is winged with black coloration on the tips of the wings, and feeds from a vertical position, with wings rising into the air. Nymphs have a flat, yellow body and leave behind white honeydew and distorted leaves as they feed. New products, like Minecto® Pro insecticide, which is recommended by Syngenta, are on the market with efficacy on ACP. The premix formulation of cyantraniliprole and abamectin offers robust control of key citrus pests, including Asian citrus psyllids, mites and leafminers. While Minecto Pro is extremely effective against ACP, its mode of action does not interfere with ACP feeding. If an infected adult has the opportunity to feed on an uninfected plant, HLB can still be transmitted. Therefore, the best course of action is to get ahead of the insect, so scout early and often and apply insecticides like Minecto Pro to prevent a population from settling in.

Don’t Underestimate Corn Rootworm

SyngentaAgronomy — Thu, 08 Jun 2017 21:42:23 +0000

Growers may have noticed lower corn rootworm (CRW) pressure in previous years, but CRW pressures can vary from year to year and location to location. This resilient pest is highly adaptable and can wreak havoc when least expected. Root damage from CRW is not evident until late in the season, often when it’s too late to fight the pest. That’s why long-term CRW control requires a consistent approach, even in years with low pressure. Consistent CRW management ensures growers’ fields are protected from possible CRW infestations, leading to higher yields. Using a robust insecticide is an effective way to consistently minimize the risk of CRW damage from season to season. Force® Evo insecticide is designed for growers looking for performance and convenience. Containing the trusted active ingredient, tefluthrin, Force Evo consistently outperforms other insecticides on control of CRW and other early-season pests, leading to improved root growth, better nutrient uptake and improved yields. When used on top of CRW traits, trials show Force brands deliver an average yield increase of 10 bu/A. Even in the absence of CRW, Force brands help increase yield because early-season pests like wireworms, white grubs and seedcorn maggots can cause more destruction than meets the eye. Bottom line, Force Evo is a risk management decision for peace of mind on every acre.

Herbicides protect corn yield potential all season long

SyngentaAgronomy — Mon, 01 Feb 2016 18:58:25 +0000

Farmers across the Midwest faced weed control challenges in 2015 due to challenging weather and weed resistance. No matter how much time and how many resources you used on weed control last year, it's more than likely weed issues will happen again in 2016. It might not look identical from state to state, town to town or even field to field, but weed pressure is just about everywhere. With corn continuing to be in high demand, you can’t afford to let weed competition threaten yield potential. That’s why season-long weed management is essential. Knowing that everyone has a unique set of challenges and that weed control can seem complicated, Syngenta offers many herbicide choices that can be tailored to your needs. Weeds compete for corn’s valuable water and light resources, making early-season weed control important to maximize yield and profit potential. Acuron® corn herbicide defeats tough weeds current products are missing through its powerful combination of four active ingredients and three modes of action. Bicyclopyrone, the newest corn herbicide active ingredient from Syngenta, helps Acuron deliver a step change in weed management with greater consistency of control and broader spectrum control of weeds such as cocklebur, morningglory, ragweed and Russian thistle. Additionally, Lumax® EZ and Lexar® EZ corn herbicides contain three active ingredients and three modes of action and are also excellent choices for pre-emergence weed control in corn. If you’re seeking total post-emergence weed control and long-lasting residual in glyphosate-tolerant corn, Halex® GT corn herbicide controls grass and broadleaf weeds until crop canopy.

Prevent blueberry crops from freezing

SyngentaAgronomy — Tue, 02 Feb 2016 22:11:40 +0000

Growers in southern Georgia and northern Florida will recall that freezing temperatures in 2015 caused severe damage to blueberry crops. Because blueberries bloom in late winter or early spring in the Southeast, the flowers and young fruit are highly susceptible to freeze and frost injury. Cold damage is not always obvious. Following temperatures below the critical level, the complete flower/small fruit will develop a water-soaked appearance, shrivel and drop. However, a very brief time at the critical temperature may damage only the pistil. Ovules, can also be damaged without any exterior symptoms. If only a few ovules are damaged, fruit development usually continues, but the fruit will ripen later and be smaller than berries with a larger number of healthy seeds. In order to maximize yield potential, it’s important to be prepared for the uncontrollable. Weather events are impossible to predict or control. The only way to combat damage from freezing temperatures and other events is to develop and implement measures and technologies that mitigate their impact, such as:

Monitor temperature
Prune
Avoid cultivation
Maintain soil moisture
Sprinkler irrigation – Overhead irrigation systems are the most widely used and practical method of reducing blueberry fruit losses to freezes in the Southeast

Following these precautionary measures can help mitigate adverse weather and increase yield potential. Photos are either the property of Syngenta or used under agreement.

Prevention is key to disease control in tomatoes

SyngentaAgronomy — Wed, 03 Feb 2016 17:17:16 +0000

Rain showers and high humidity make it easy for bacteria to attack tomato plants, which can be devastating to an unprotected crop. More prevalent in wet seasons, bacterial spot can cause severe damage to the plants, including leaf and fruit spots, which result in reduced yields, defoliation and sun scalded fruit. Prevention is the key to disease control. Once the disease has started in a field, control is very difficult, especially during wet weather. Here are some tips to prevent bacterial spot:

Avoid sprinkler irrigation
Produce plants in sterilized soil
Avoid fields that have been planted with peppers or tomatoes within one year
Rotate with a non-host crop
Remove and discard fall plants, followed by deep tilling

When bacterial speck, spot and blight threaten tomato crops, Actigard^® plant activator provides unprecedented results. Actigard activates the plant’s natural defense system and protects the tomato plant, much like a vaccination. Its systemic movement lets Actigard move through the plant quickly for all-over protection. Additionally, its low use rate and excellent fit in an integrated pest management program make Actigard a great choice for any disease prevention plan. Improved protection with Actigard means a decrease in copper sprays, which can save time and money and reduce resistance concerns. Photos are either the property of Syngenta or used under agreement.

Reflect on 2015 soybean season for 2016 planning

SyngentaAgronomy — Thu, 04 Feb 2016 22:20:44 +0000

In 2015, adverse weather conditions played a major role in soybean planting. Some parts of the central and eastern Corn Belt experienced an early planting window followed by a long wet period that kept many from finishing planting their soybeans in a timely manner in 2015. With the cool, wet conditions, sudden death syndrome (SDS) was a concern for many growers. This year, experts at the University of Illinois recommend preparing for the following potential problems in soybeans:

Adverse weather conditions
Weed resistance

As 2016 planting approaches, take some time to reflect on last year’s growing season. Evaluating what positively or negatively affected soybean yields one year can help provide insight for the next year’s management plans and variety selections. For 2016 planting, new NK® Soybeans S37-Z8 and S39-C4 brands perform extremely well in variable environments. They offer strong SDS resistance and very good standabilty, allowing for ease of harvest and maximizing yield potential. In 2015, NK Soybeans S37-Z8 brand out-yielded Asgrow® varieties by an average of 1.7 bushels per acre (bu/A) in 394 trials and out-yielded Pioneer® varieties by an average of 2 bu/A in 315 trials in Illinois, Indiana and Ohio. Similarly, NK Soybeans S39-C4 brand out-yielded Asgrow varieties by an average of 3.1 bu/A in 312 trials and out-yielded Pioneer varieties by an average of 3.3 bu/A in 239 trials in the Illinois, Indiana and Ohio, as well.

Potassium & fertility: Higher alfalfa yields

SyngentaAgronomy — Mon, 08 Feb 2016 20:20:18 +0000

Many elements are essential nutrients for plants. In relatively large amounts, the soil supplies macronutrients: nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. According to Purdue University, to keeps plants healthy and give them the best chance to compete against insects, diseases and other stresses, a balance of these nutrients is essential. The proper amount of potassium is critical for growth and development, particularly for alfalfa. Potassium helps alfalfa crops become higher-yielding and higher-quality, all helping maximize performance and profitability. Potassium also:

Helps regulates enzymatic processes in the plant
Enhances root development and tolerance to temperature extremes
Improves drought tolerance
Minimizes susceptibility to disease

When thinking about applying potassium to alfalfa crops, its best to take a balanced approach. It’s extremely important to consider the plant’s needs before fertilizing. Therefore, be sure to test the soil for potassium levels and fertilize accordingly. Adequate nutrition maintains alfalfa’s vigor and ability to deal with stresses. Proper levels of nitrogen, phosphorus, sulfur and potassium helps ensure high yields of quality forage, ultimately helping you grow more alfalfa.

Reflecting on successful 2015 product introductions

SyngentaAgronomy — Tue, 09 Feb 2016 18:01:48 +0000

North Carolina: Few states can boast as diverse an array of crops as North Carolina. With this diversity comes the challenge of managing weed and pest pressures across multiple crop programs. For growers in the Southeast, products that are flexible across multiple cropping systems and effective against multiple weed species and disease complexes are essential to ensuring crop success. During the 2015 season, the Syngenta Grow More Experience Site in Kinston provided a real-world environment where we demonstrated both the flexibility and efficacy of a wide range of Syngenta products. A harder-working, longer-lasting fungicide The spring wheat crop gave me a first glimpse of the control Trivapro™ fungicide provides against diseases like powdery mildew and Septoria, that were present at the site. We had periods of heavy rainfall in May — in just one weekend, we received seven inches. Those conditions compounded the disease pressure and helped us see how Trivapro helps crops stand up to harsh environments. Trivapro is labeled for use in corn, soybeans and wheat, and it contains three unique active ingredients: azoxystrobin, propiconazole and Solatenol^® fungicide — a powerful new SDHI technology that binds to the waxy layer of the plant for increased residual control. In addition to being deployed as an active ingredient in Trivapro, Solatenol is an active ingredient in three additional fungicides for use in other crops. Two of these fungicides, Aprovia^® Top, labeled for the cucurbit and fruiting vegetable family of crops, and Elatus^®, developed for the peanut and potato markets — were also showcased at the site. Grow More Experience Site wheat plots demonstrated the benefits of Syngenta seed treatments, AgriPro^® wheat varieties, Trivapro and Quilt Xcel^® fungicides, Palisade^® EC plant growth regulator and Syngenta herbicides An additional mode of action for control of Oomycete diseases North Carolina’s heritage has strong ties to both tobacco and the pickling industry. In tobacco, black shank is among the most destructive and difficult-to-manage diseases. For cucumber growers, the use of multiple modes of action to control downy mildew is imperative. That’s why I was excited to observe the performance of Orondis^® fungicide, with the active ingredient oxathiapiprolin. It’s a new class of chemistry, and it’s effective on the downy mildews, as well as soil-borne and foliar Phytophthora species, such as late blight. As the only active ingredient in FRAC Group U15, oxathiapiprolin is not cross-resistant to any other fungicide; it offers built-in resistance management when incorporated in a season-long Oomycete disease control program. Since it’s labeled for use in fruiting vegetables, cucurbit vegetables and leafy vegetables — as well as onions, potatoes and tobacco — its cropping flexibility is remarkable. Visitors witnessed the efficacy of Orondis^® Ridomil Gold^® SL fungicide, which combines the power of Orondis and Ridomil Gold^® fungicides, on black shank. We saw how Orondis Ridomil Gold SL offers preventive, systemic and residual control of black shank — protecting the crop at its most active growth stages — and we were very excited to observe the length of residual. Visitors also saw the benefits of Orondis^® Opti fungicide, a combination of Orondis and Bravo Weather Stik^® fungicide, in cucurbits. A step change in weed management For corn growers nationwide, the introduction of Acuron^® corn herbicide was met with much anticipation. The North Carolina market was no exception. We’re really excited about Acuron corn herbicide because it brings activity to more than 70 troublesome weeds and broadens the spectrum of weed control growers need. Morningglory is one of the toughest weeds Southeastern corn growers can face. Fortunately, morningglory is among the tough weeds that Acuron corn herbicide controls, as can be seen in the photo above. I expect there will much more to report from Kinston in 2016.

Protect almonds at their most vulnerable

SyngentaAgronomy — Mon, 15 Feb 2016 16:45:13 +0000

Almond bloom is around the corner. Emerging from dormancy, almonds tree buds bloom in preparation for pollination between late February and early March. During this stage, the almond flowers are vulnerable to a number of threats. Weather patterns in the past have shown that chilling February temperatures can wreak havoc on almond crops. To protect crops from the unpredictable, make sure to have a frost protection program in place. Frost protection can be provided by the following:

Running water
Proper soil and groundcover preparation
Sprinklers and micro-sprinklers
Moving air (helicopters, wind machines, etc.)

During wet weather, almond trees are also susceptible to bloom and foliar diseases. Deciding when to spray and what fungicides to use can be difficult. Be sure to accurately assess the diseases present in orchards and select fungicides carefully. Remember not all fungicides are equally effective on all diseases. Active against a wide range of fungal diseases, Vangard® WG fungicide provides long-lasting protectant activity to help fight brown rot, jacket rot and shot hole in almonds. Use it as a first spray to protect delicate flowers from brown rot blossom blight (Monilinia spp.) and suppress other fungal diseases.

Pest pressures and proteins. What’s the link in sweet corn?

SyngentaAgronomy — Tue, 16 Feb 2016 17:19:49 +0000

It’s the time of year when sweet corn growers begin thinking about and purchasing seeds for the upcoming growing season. A substantial part of that decision focuses on what pest pressures will come into play and which seeds hold up to those pressures best. Common pests that many growers deal with each season include European corn borer, corn earworm and fall armyworm. These three lepidopteran insects can wreak havoc on a corn field and leave a grower with an enormous loss in yield and profit as they chew through ears of corn. Effective methods for controlling these pests include planting sweet corn varieties with genes that express the production of a crystalline protein (Cry) from Bacillus thuringiensis (Bt). When lepidopteran insects consume a small amount of plant tissue from these varieties, the Bt protein binds to their digestive systems, causing them to stop feeding and die within 48 hours. Bt protein is embedded within corn leaves, silks, stalks and ears throughout the growing season, providing comprehensive protection that won’t wash off in the rain or degrade in the sun. Attribute® II varieties include a trait stack that expresses the production of both Cry proteins and vegetative insecticidal proteins (VIP), an entirely new class of proteins. Vip3A binds to different receptors than Cry proteins within an insect’s mid-gut membrane, and can greatly reduce the risk of insect resistance. Galen P. Dively, Professor Emeritus and IPM Consultant at the University of Maryland says, “Bt sweet corn clearly offers a more targeted and sustainable tool to control insect pests and significantly reduces the number of conventional insecticides. Based on multiple-year field trials, Attribute II hybrids reduced silk sprays for ear-invading caterpillars with multiple Bt proteins expressed that provide virtually 100% control of the pests. Other studies have not reported any adverse effects on beneficial insects in Bt sweet corn.” Dively also confirms that, as a result of having minimal to no spraying, using Bt sweet corn generally results in cost savings over conventional control programs, and can significantly reduce the time that growers spend in managing lepidopteran pests, as well as reduce the exposure risk from handling and applying insecticides.

Scout wheat crops now to get ahead of stripe rust

SyngentaAgronomy — Wed, 17 Feb 2016 22:20:07 +0000

Stripe rust dominated wheat fields in 2015. A severe outbreak of stripe rust can cause up to 40 percent yield loss, so it’s important to be prepared and scout early for this disease. Common symptoms include:

Long stripes of small, yellow or orange blister-like lesions (pustules)
Spores that are easily dislodged and may appear as orange dust on clothing

Stripe rust normally thrives in cool, humid weather, but research indicates that it has evolved to adapt to warmer temperatures. Although some winter wheat is still covered in snow, it’s important to monitor crops and be diligent about scouting. With higher moisture, the opportunity for infection is greater. Keep an eye on fields and be ready to treat with a fungicide if necessary. One strong defense measure is to plant a certified seed variety with tolerance to stripe rust. Where adapted, some AgriPro® brand varieties from Syngenta offer good stripe rust tolerance. Planting certified seed varieties helps ensure:

Smoother plantability
Seedling vigor
Improved germination and emergence

Syngenta also offers Trivapro™ fungicide, the hardest-working, longest-lasting fungicide on the market. Trivapro gives wheat growers the tool they need to help shut down existing disease and prevent future infections. Trivapro controls diseases like Septoria leaf and glume blotch, rusts, tan spot, net blotch, powdery mildew, barley scald, spot blotch, black point and Helminthosporium leafspot. It’s important to regularly scout fields to track the presence of stripe rust and other diseases in your fields. Being proactive about crop protection will help maximize profit potential and ultimately help grow more wheat.

Proper pre-planting preparation in corn

SyngentaAgronomy — Fri, 19 Feb 2016 16:50:06 +0000

Looking forward to spring, many growers are anxiously waiting to get into the field and start planting. Before putting seed in the ground, however, there are several critical aspects of crop production that growers should consider to ensure their crops achieve a healthy start:

Equipment preparation
Seedbed preparation
Soil testing and fertility balance
Create a management plan tailored to your hybrid
Choose certified seed
Use an effective burndown herbicide
Proper tillage

Several weed species, especially kochia, giant ragweed and marestail, emerge early in the season, before planting, and need to be controlled before they grow too large. A properly timed pre-emergence herbicide application at a full rate can help provide lasting weed control long into the season, which can ultimately help save money and time. Acuron® corn herbicide defeats tough weeds other products are missing, through its powerful combination of four active ingredients and three modes of action. Bicyclopyrone helps Acuron deliver a step change in weed management with improved and more consistent control of tough weeds, including ragweed – mentioned above. Profitable corn production starts with proper pre-planting preparation. Using all the tools in your box, and applying a pre-emergence herbicide, can help you maximize profits and grow more corn.

Variety selection considerations for tomatoes and peppers

SyngentaAgronomy — Mon, 22 Feb 2016 15:26:19 +0000

It’s time to order seed and get ready for the spring crop. Variety selection is one of the critical decisions that growers must make each season. According to the University of Florida extension, it’s important to consider demands in the marketplace when selecting varieties: production systems and training methods, diseases and insect pests you might incur throughout the growing season, and yields. For tomatoes, Syngenta offers a highly diversified product pipeline with unique, multi-disease resistant varieties, to help ensure a sustainable production of high-yielding, high-quality tomatoes for different markets in the industry. Tomato varieties from Syngenta are designed according to the demands of key production slots, and provide:

Vetting soybeans for a hidden pest

SyngentaAgronomy — Tue, 23 Feb 2016 16:22:36 +0000

Most threats to your fields are visible: insects, weeds, weather, disease and even the occasional wildlife. This makes it easier to determine cause-and-effect when it comes to your soybean yields. However, when a pest is not visible, it’s difficult to know what is hindering yield. Unfortunately, the No.1 soybean pest in the U.S. happens to be invisible to the unaided eye and does not show many, if any, visible symptoms. Soybean cyst nematode (SCN) attacks soybeans at the roots and quietly thwarts your yields. Due to the absence of aboveground symptoms, oftentimes SCN yield damage is attributed to cultural or environmental conditions, according to the Iowa State University Extension. This can lead to the build-up of undetected SCN populations. This invisible damage means you could be unaware of your SCN problems. It’s important to submit soil samples to your local state extension to test for SCN presence. Syngenta encourages you to also develop a proactive management plan to protect your yields from SCN. If you suspect SCN in your fields, consider treating your soybeans with Clariva^®Complete Beans seed treatment, a combination of separately registered products. Clariva Complete Beans provides crops with triple protection against insects, disease and nematodes during the critical early-growth stages. The nematicide component of Clariva Complete Beans provides lethal activity against SCN all season long, which is crucial as SCN reproduces throughout the growing season. It also reduces the selection pressure that renders genetic resistance less effective, a problem that is increasing as populations adapt to genetic resistance. Clariva Complete Beans also reduces damage from SCN-related diseases such as sudden death syndrome. A proactive SCN management program that includes a seed treatment like Clariva Complete Beans is essential to protecting your soybeans from increased yield loss and increasing your return on investment. Help soybeans start strong by preparing for SCN so that you can grow more soybeans.

Corn hybrid selection begins with maturity

SyngentaAgronomy — Thu, 25 Feb 2016 21:13:55 +0000

As growers make their final planting preparations, some may be asking themselves whether the hybrid selections they made in late fall/early winter are still the right ones today. Especially factoring in the continuing reality of low corn prices, Syngenta agronomists are recommending that growers still contemplating their seed decisions keep the following in mind. Most selection decisions begin with relative maturity (RM) – these ratings are relative to physiological maturity and largely driven by a combination of growing degree days (GDDs) planting date. When building a plan for the 2016 growing season, it’s important to identify the GDD range and average required for a hybrid to reach physiological maturity (black layer) within your local geography. Planting multiple hybrids of varying maturity will reduce risk in three main areas:

Agronomics (emergence, stalk strength, disease tolerance)
Harvest management (harvest moisture)
Genetic diversity (yield, drought tolerance)

Traditionally, about 60 to 70 percent of a grower’s portfolio is focused on the core RM zone (i.e. 100-day RM), with 10 to 20 percent focused on earlier RM and the remainder on later RM. Keep in mind that there is typically more yield variability within a given RM group – or put another way, more yield stability across multiple RM groups. According to the University of Minnesota, grain moisture at harvest also increases steadily with increasing relative maturity. On average, grain moisture at physiological maturity increases by 0.25 to 0.5 percent with each one-day increase in relative maturity. Selecting hybrids of appropriate maturity is important for a balance between yield potential and managing grain moisture at harvest, ultimately helping to grow more corn.

Looking back to look ahead

SyngentaAgronomy — Fri, 26 Feb 2016 16:49:57 +0000

After working at the Dalhart, Texas, Grow More Experience site this past year, we created a list of things to consider as growers begin their 2016 season.

Start early to control weeds. Growers need to start clean to keep their fields clean. When looking for a herbicide to control weeds in corn, we recommend a herbicide like Acuron®. At the site, we trialed Acuron by applying it pre-emergence followed by a post-emergence application of Halex® GT herbicide plus AAtrex® 4L. This program has been excellent in controlling Palmer amaranth. Acuron followed by Halex GT provided residual control even 45 to 60 days after planting, which is when the competitor products started to break down.

Find the right herbicide to control tough weeds. The Dalhart area has a lot of Palmer amaranth and glyphosate-resistant pigweed, which can be difficult to control. After doing a bare ground herbicide trial at the site, we found that Acuron applied pre-emergence was able to handle these weeds and others like Russian thistle and kochia. At the end of the season, these plots were essentially 100 percent clean.

Use a flexible fungicide with good residual control. This past year we used Trivapro™ fungicide in our test plots at both the V4-V8 stage and a two shot at the R1 stage and compared it to competitor products. Trivapro by far had the best residual control throughout the season. Consider using a fungicide with this type of residual control and flexibility in application timing in 2016. Trivapro also offers tank-mixing capabilities, which is great for growers looking to apply a herbicide or insecticide at the same time.

Scout for insects early and often. One of the most challenging insects in our area is the spider mite. This past year, they were tougher to control even with miticides because of the rainy May and June. We recommend getting out early and often this upcoming year to scout for these and other insects, such as fall armyworm and earworm. Better to be safe than sorry when it comes to something like this!

Plan ahead for weed management in soybeans

SyngentaAgronomy — Mon, 29 Feb 2016 16:13:11 +0000

When it comes to weeds and herbicide resistance, it’s not enough to just nip them in the bud. It’s important to manage the problem long before the weeds even have a chance to sprout. Researchers with the University of Minnesota Extension explain that after repeated use of the same herbicide, herbicide-resistant weed populations can rapidly grow, pushing the number of resistant weeds past a manageable threshold. In fact, it’s common to go from excellent control of a particular weed to very poor control within one growing season, creating a costly problem. To help avoid this issue, it’s important to develop a strategic management plan to preserve herbicide options. A good weed management plan can cover fields for three to five years. Focusing on long-term, comprehensive weed management strategies can help minimize crop loss over multiple seasons, reduce the weed seed bank and help delay the development of herbicide resistance. Consider the following:

Start with a clean field and control weeds early by using a burndown treatment or tillage in combination with a pre-emergence residual herbicide
Employ integrated weed management practices with multiple modes of action
Scout fields after herbicide application to ensure you have thoroughly controlled the weeds
Avoid allowing weeds to reproduce
Monitor sites and clean equipment between sites to prevent the spread of weed seed
Implement cultural practices such as cultivation and crop rotation

Assessing weed management options will help create a customized, effective plan to achieve long-lasting weed control. Apply herbicides that target weeds with confirmed or potential herbicide resistance. Syngenta offers several herbicide programs with diverse options for multi-year plans. Here are a few to consider:

A burndown application like Gramoxone® SL 2.0 herbicide to start clean and eliminate early-season weed competition
Boundary®, BroadAxe® XC and Prefix® herbicides provide broad-spectrum pre-emergence residual control of a full range of tough broadleaf and grass weeds
Flexstar® GT 3.5 and Touchdown Total® herbicides offer effective post-emergence management targeting difficult-to-control weeds

When combined with cultural practices such as crop rotation and tillage, these weed management options can help reduce the weed seed bank, maximize herbicide diversity and fight resistance.

Start early to control weeds

SyngentaAgronomy — Tue, 01 Mar 2016 15:06:21 +0000

It’s no secret that irrigation is necessary to grow corn in northern Texas. It also shouldn’t be a secret that to get the most from irrigation it is necessary to control weeds. As growers plan for 2016, they should consider using Acuron® corn herbicide to control weeds early. We’ve been screening Acuron at the Dalhart Grow More Experience site for close to three years and have seen it perform really well. This past year, we trialed Acuron in a one-pass program and a two-pass program in combination with other herbicides, such as Halex® GT. We compared it to competitive products in field and bare-ground settings. Two programs in particular stand out from this past year. One program applied Acuron pre-emergence at 1.25 qt/A followed by an early post-emergence application of Halex GT plus AAtrex® 4L herbicide. This is a good program to use for those looking to control weeds early. Acuron followed by Halex GT has been a very consistent and proven program in our Grow More Experience test plots, especially with controlling Palmer amaranth. After about 45 to 60 days, we would start to see the competitive products break down. Acuron followed by Halex GT had far better season-long residual control of tough weeds. The second program is one-pass of 2.5 qt/A Acuron, which can be used by those looking for cost efficiencies. With glyphosate-resistant pigweed already in our area, a one-pass program of Acuron can tackle this weed and cut down on glyphosate applications. Grow More Experience site bare ground Acuron trial showing the untreated (left) and Acuron applied at 2.5 qt/A (right).

Stay ahead of weeds in cole crops

SyngentaAgronomy — Thu, 03 Mar 2016 16:15:22 +0000

Whether cole crop seeds and transplants are just hitting the soil or they’ve begun to emerge, weeds pose a season-long risk and efforts should be made to mitigate the risk where possible. Researchers and professors at the University of Florida IFAS Extension recommend a combination of management practices designed to suppress weeds throughout the entire year. Crop rotation, cover cropping, high planting density, mulching, cultivation, flooding and herbicide use are all part of a recipe for improved harvest quality and yield. One of the greatest hazards to a healthy crop is early-season weeds, which can quickly choke out seedlings and are a haven for all types of insects. A careful balance of pre-emergence and post-emergence herbicides with proper cultivation techniques can give growers a leg up. Getting weeds under control early is crucial for success. According to the University of California, Davis, the first 30 days after seeding are critical for weed control. After that, most cole crops produce enough shade to compete and suppress weeds. To protect cole crops from early-season weeds, Syngenta offers several herbicide options:

Use Gramoxone® SL 2.0 herbicide as a preplant to start clean and eliminate early-season weed competition
Apply Dual Magnum® herbicide immediately after planting for season-long, full weed control activity on annual broadleaf and grass

By combining crop production management practices with early-season herbicides, weeds can be effectively managed through the entirety of the season.

Defend cucurbits from downy mildew

SyngentaAgronomy — Fri, 04 Mar 2016 15:43:22 +0000

Downy mildew is an important disease in cantaloupe, cucumber, pumpkin, squash and watermelon, especially in places with high humidity and rainfall, like the eastern U.S. Most years, downy mildew is a late-season problem on squash and pumpkin in the eastern and central U.S., however in recent years it has become more prevalent in cucumbers. Downy mildew is sometimes called “wildfire” because of how rapidly it progresses. Diseased leaves have two major effects:

Reduced yields and a greater chance of deformed fruit (especially in cucumber)
Sunscalded fruit (especially in watermelon and winter squash)

Since epidemics of cucurbit downy mildew can develop rapidly, it’s critical to initiate a preventive program early, or before conditions become favorable for disease spread. A product like Orondis^® Opti fungicide which exhibits exceptional long-lasting disease control and systemic redistribution brings best-in-class protection against downy mildew in all types of cucurbits. Combining the proven multi-site action of chlorothalonil, with the unique mode of action of oxathiapiprolin, Orondis Opti gives double punch disease control and built in resistance management. To find out if Orondis Opti is approved for use in your area, visit this page. Since wet weather is conducive for downy mildew, it’s important to choose a fungicide that will last throughout these conditions. Syngenta also offers Bravo Weather Stik® fungicide for residual control that sticks and stay on cucurbits for protection making it a leading contact fungicide. Additionally, Syngenta offers Quadris Top® fungicide to protect cucurbits from a broad spectrum of profit-robbing diseases.

Five factors corn growers should consider before planting

SyngentaAgronomy — Mon, 07 Mar 2016 16:38:35 +0000

Spring is near, and so is planting. As corn growers approach this critical time of the year, there is always a lot to consider. Here are some top factors to keep in mind to help start the season strong:

The right hybrids. For growers still making their final seed purchasing decisions, remember that soil type, pest pressures and other environmental concerns should all be taken into consideration. Even with excellent season-long crop management, corn will not yield at its full potential if the hybrid isn’t right for the field. Syngenta offers a range of Golden Harvest® Corn hybrids featuring strong genetics and unique traits and technologies to help growers get the most out of their acres.

Soil temperatures. Many things, such as amount of crop residue and soil type, influence soil temperature. Growers should take readings in multiple spots during mid-morning to get the most accurate results. Planting can start as long as soil temperatures are near 50 degrees and the weather outlook calls for warmer weather ahead.

Soil dryness. Soil that is too wet can cause problems with the planter’s ability to open and close the seed slot. Unclosed slots can result in sidewall compaction, pest problems, poor root establishment and opportunities for overexposure to herbicide.

Plant spacing. Plant spacing plays an important factor in maximizing yields. Improper plant spacing and spacing variability can cause yield losses up to 4.7 bushels per acre for every inch increase in the standard deviation from plant to plant. To prevent this, growers should check their planters before they start. Poorly maintained meters, wrong meter discs for the size of the seed, worn chains, clutches, seed tubes and planting too fast can all contribute to plant spacing variability.

A pre-emergence herbicide. Weeds compete with corn for valuable water and light resources, which can ultimately affect corn yield. To control early emerging weeds, use a properly timed pre-emergence herbicide application at full rate to provide lasting weed control long into the season. Acuron® corn herbicide contains four active ingredients and three modes of action that help it defeat tough weeds. Bicyclopyrone helps Acuron deliver a step change in weed management with improved and more consistent control of tough weeds.

Rootworm resistance could pose problems for Illinois growers

SyngentaAgronomy — Tue, 08 Mar 2016 15:10:12 +0000

ILLINOIS: Corn rootworm is a major economic pest in corn in the U.S. Although severity of infestations varies from year to year, University of Illinois researcher Nick Tinsley predicts western corn rootworm (CRW) resistance to Bt toxins will likely become an issue for Illinois corn growers. It has already been confirmed in Iowa, Nebraska, Kansas, South Dakota and Minnesota. To avoid CRW resistance, he recommends using an integrated management approach to combat this insect. Syngenta is also closely monitoring CRW populations and supports integrated management practices that include crop rotations, hybrids with multiple modes of action and soil insecticides like Force® brand insecticides. With more than 25 years of proven performance, Force brands continue to:

Provide top-rated control of corn rootworm and other early-season pests
Deliver high-performance insect control even in heavy pressure areas
Enhance yield when applied over CRW-traited acres

As seen in this photo from Monticello, IL, at the end of the 2015 season, the plants on the right treated with Force withstood CRW pressure better than those on the left not treated with Force. You can see the root mass is larger, which contributed to the plants being able to take up water and nutrients better to produce thicker, stronger stalks. Stronger root systems and stalks mean a healthier plant, which can help maximize return on investment and ultimately help grow more corn.

Be proactive, defend against cotton nematodes

SyngentaAgronomy — Wed, 09 Mar 2016 16:12:47 +0000

Cotton nematodes are a threat to all growers – they have been identified in every state where cotton is grown. Feeding primarily on the young roots of cotton plants, cotton nematodes are capable of extensive damage including:

Stunting
Reducing the plant’s ability to absorb water and nutrients
Providing locations for other disease-producing organisms to enter the plant (Fusarium, bacteria, etc.)
Causing plant stress

Knowing the history of cotton fields is important to managing cotton nematodes efficiently. Cropping history, soil texture, knowledge of injury in local soils and having a baseline estimate of nematode populations can help get a jump start on preventing and managing nematodes. Additionally, using these cultural practices can help reduce populations:

Rotate with non-host crops
Control susceptible weeds
Precision tillage

Additionally, using a seed treatment like Avicta® Elite Cotton Plus with Vibrance® nematicide/insecticide/fungicide, a combination of separately registered products, can help defend against early-season diseases, in addition to stellar protection against insects and nematodes. The additional active ingredient to thiamethoxam allows cotton growers who have come to rely on Avicta® Complete Cotton seed treatment, a combination of separately registered products, to better combat early-season insects with increased product consistency.

Control weeds as winter wheat breaks dormancy

SyngentaAgronomy — Thu, 10 Mar 2016 15:08:34 +0000

CENTRAL PLAINS: With winter wheat across the Central Plains breaking or expected to break dormancy soon, growers need to be prepared to control broadleaf weeds, such as kochia (pictured above), particularly those showing resistance to herbicides. According to Kansas State University agronomists, the “weed-and-feed” approach is a common and sound way to meet two needs at once. When dealing with herbicide resistance, Syngenta recommend growers take a proactive approach, particularly with weeds showing resistance to multiple modes of action. When weeds become resistant, they are no longer controlled by previously effective herbicides. This is the case with kochia and glyphosate, so even if growers aren’t seeing reduced control on their farms, someone close-by likely is. To combat herbicide resistance and protect yield, growers can:

Follow label instructions and use the full recommended herbicide rate
Time applications to weeds in their early growth stages
Use multiple effective herbicide modes of action with overlapping efficacy by using mixtures with residuals
Deploy diversified management programs, such as cover crops, mechanical weed control and crop rotation

At Syngenta, we closely monitor the spread of herbicide-resistant kochia and support early spring herbicide applications in winter wheat. Herbicides like Amber^® or Rave^® are excellent tools to stop weeds from interfering with a developing winter wheat crop. Contact your Syngenta representative or retailer about product availability.

Choose a sunflower hybrid that’s right for your field

SyngentaAgronomy — Fri, 11 Mar 2016 16:38:08 +0000

Sunflower hybrid selection is one of the most important decisions a grower makes. There are a number of factors that go into the selection process – classes of hybrids, yield, maturity, standability, pest and disease tolerance, just to name a few. According to the National Sunflower Association, here are the factors growers need to consider:

Decide which characteristics are absolutely necessary
Plant hybrids that have been successful in the past
Plant strip trials
Seek yield data from multiple locations and years
Rely on trials that mimic personal field situations
Think of characteristics that can lower production costs
Try a little bit of something new each year

Syngenta offers sunflower hybrids that are localized to growers’ fields. We screen germplasm around the world to identify genetics that fit U.S. growing conditions so that our sunflower hybrids meet local needs. Growers receive an added bonus on select hybrids with Unistand™, an innovative technology that provides growers with easier, more accurate planting and improved crop emergence. Unistand always produces a size 3 seed and consistently delivers excellent singulation during planting.

The ripple effect of early-season soybean management choices

SyngentaAgronomy — Mon, 14 Mar 2016 14:14:07 +0000

Not every farm is the same, so it’s important to have an understanding of what’s happening both above and below the soil. Knowing which insects, diseases, nematodes and weeds are present in soybean fields will help growers prepare accordingly and maximize yields. Variety selection and weed management are two early-season factors that can have a ripple effect extending throughout the season. Insect, disease and nematode management often starts with variety selection. Picking the right varieties goes a long way to maximizing yields at harvest. Michigan State University Extension agronomists recommend planting a range of maturities to mitigate yield loss related to pest and environmental stressors and shattering at harvest. They also recommend growers rotate soybean varieties from year to year and from field to field. This practice can help prevent pests and nematodes from building up resistance to the genetic sources bred into the varieties. NK^® Soybean varieties are available in maturity groups 000 through VII. The range of maturities, genetics, disease and pest resistance options, and agronomic packages allows growers to choose a variety that is tailored for their growing environment, which ultimately helps combat the season’s challenges and grow more soybeans. Another early management focus is weed control. Weeds compete for nutrients and sunlight that are essential to a crops’ success. Researchers with the University of Wisconsin Extension say managing early-season weeds helps to maximize growth, which causes soybeans to canopy more quickly. Planting into clean fields and using a residual pre-emergence herbicide also extends the timeframe for a post-emergence herbicide application. By taking the time to manage weeds earlier in the season, growers help to reduce the risk of more popping up later in the season. Syngenta recommends that growers take the proper steps to ensure they’re planting into clean fields in 2016. Apply burndowns herbicides, if needed, and ensure fields are weed-free before planting. Additionally, spraying weeds again, before they reach 4 inches, is important. Sign up for the Know More, Grow More Digest to receive twice monthly agronomic e-mail updates pertinent to your area.

Coming soon: Simpler insecticide applications for corn

SyngentaAgronomy — Mon, 14 Mar 2016 15:44:26 +0000

New technologies are continually developed to alleviate growers’ challenges like weeds, disease and insect pests in the field. Although these technologies may provide the control growers need, some products can come with their own challenges and may not be simple or convenient to use. Growers want convenience through streamlined applications, simple cleanout and compatible tank mix partners. One challenge is soil-dwelling pest control. Insects can reduce yield and affect overall plant health by increasing a corn plant’s susceptibility to disease, reducing the plant’s ability to uptake water and nutrients, which can lead to stunted growth and lodged or goose-necked corn. Liquid insecticides are among the most convenient products to deliver control of corn rootworm (CRW) and other early-season pests, such as white grubs and wireworms, but may come with formulation challenges, including instability in cold weather conditions and incompatibility with commonly used starter fertilizers. Force® Evo is a new liquid, soil-applied insecticide (SAI) under development for growers who seek control of these pests, with additional formulation benefits. As an improvement from Force CS, Force Evo will have improved cold weather tolerance and freeze-thaw performance, which results in better flowability, easier cleanout and a four to six times reduction in quantifiable residues on equipment surfaces. Trials also showed that Force Evo has strong fertilizer compatibility. Anticipated for use in the 2017 growing season, growers can expect the superior pest control as seen with previous Force insecticides in a simpler, convenient application.

New herbicide for broadleaf weed control in cereals

SyngentaAgronomy — Tue, 15 Mar 2016 14:49:37 +0000

Yield-robbing weeds infest wheat fields, compete with crops and can ultimately impact yield potential and crop quality. Growers turn to herbicides as one method of minimizing these threats and protecting their wheat. Pending registration for 2017 use, Talinor™ herbicide is the newest cereals broadleaf herbicide from Syngenta. It offers selective, post-emergence broadleaf weed control in barley, spring wheat (including durum), and winter wheat. Talinor contains the newest active ingredient in cereal herbicides, bicyclopyrone, combined with bromoxynil. Together, these two active ingredients will deliver excellent standalone control of more than 50 tough-to-control broadleaf weeds, including kochia, mayweed chamomile, Russian thistle and wild buckwheat. With the combination of these two active ingredients, Talinor will serve as an important tool to help combat weed resistance. This new broadleaf herbicide will be an ideal fit for growers in North Dakota, and will also be available to growers in the surrounding Northern Plains states, as well as the Pacific Northwest. University trials and Syngenta Grow More Experience sites will showcase Talinor this summer. Growers and retailers can contact their Syngenta agronomist for additional technical information about Talinor herbicide.

Pest Alert: Reports of cereal rust increase

SyngentaAgronomy — Wed, 16 Mar 2016 19:01:29 +0000

Growers should continue to scout and monitor their fields for signs of cereal rust as reports of this disease continue to come in from Arkansas, Colorado, Louisiana, Missouri, Oklahoma, Texas and Washington. Winds, humidity and rainy weather conditions are conducive to disease flare-ups across these cereal-growing regions during mid to late March. Kansas wheat growers should also be on high alert for cereal rust in fields as winds continue to come out of the south. Growers should be scouting and walking their fields now and continue to do so frequently throughout the season, looking for rust in wet areas, denser canopies and field borders. Even if you don’t see rust, but your neighbors are reporting it in their fields, it could be beneficial to make preventive fungicide applications since this disease can show up seven to 10 days after spores have blown across and into a field. If you’re making the first fungicide application of the season, Syngenta agronomists recommend using Trivapro™ fungicide at herbicide timing, followed by an additional application at flag leaf, if necessary. This latest fungicide innovation for wheat from Syngenta works ten times harder than competitive brands. Trivapro creates a disease shield with translaminar movement and binds to the leaf’s waxy layer for extended stay-put protection, giving wheat growers the tool they need to help shut down existing disease and prevent future infections. Another option would be either Quilt Xcel® or Alto® fungicide at herbicide timing, followed by an application of Trivapro during the flag leaf stage, if necessary. This helps provide protection throughout the growing season with control and greening effect for healthier, higher producing plants. It’s important to regularly scout fields to track the presence of stripe rust and other diseases. Being proactive will help maximize profit potential and ultimately help grow more wheat.

Wet weather conditions are conducive for tomato diseases

SyngentaAgronomy — Thu, 17 Mar 2016 15:28:36 +0000

MID ATLANTIC – We’ve said that prevention is key to disease control in tomato fields. With the heavy rain and wet weather conditions experienced this winter, Mid-Atlantic growers are in a perfect storm for intense disease pressure. To give crops a fighting chance, proactive management will be more important than ever. Rain showers and high humidity make it easy for diseases to attack tomato plants, which can be devastating to an unprotected crop. According to a Penn State University professor of plant pathology, be on the lookout for these three damaging diseases this year:

Late blight
Bacterial diseases (bacterial spot and speck)
Septoria leaf spot

Controlling diseases can be challenging, so scouting early and often is critical and should be continued throughout the season. Additionally, check with local university extension teams to see where disease outbreaks have been confirmed and utilize all resources available to help combat infection. A product like Orondis^® Opti fungicide, which exhibits exceptional long-lasting disease control and systemic redistribution, brings best-in-class protection against late blight in tomatoes. Combining the proven multi-site action of chlorothalonil, with the unique mode of action of oxathiapiprolin, Orondis Opti also offers built-in resistance management and can be included in a season-long disease control program with other fungicides such as Inspire Super^® and Revus Top^®. To find out if Orondis Opti is approved for use in your area, visit this page. In addition, Actigard^® plant activator activates the plant’s natural defense system and protects the tomato plant, much like a vaccination. Its systemic movement lets Actigard move through the plant quickly for all-over protection. No matter what fungicide is chosen to protect tomato crops, scouting and proper timing applications are critical to healthy fields.

Soybean growers: Your guide to fight weed resistance

SyngentaAgronomy — Fri, 18 Mar 2016 14:25:35 +0000

For many growers, pest resistance is a nightmare come true. Whether it’s insects, diseases or weeds, pressures on soybeans seem to be getting stronger each year despite evolving management practices. However, these threats are not indiscriminate. Failure to address any one of these threats when building your seasonal management plan will directly cause a breakdown in profitability in your soybean fields. Whether resistance has already developed in your fields or you fear that it will soon, we’ve laid out a point-by-point guide to help you address one of the most challenging types of pest resistance: herbicide resistance. Start clean with tillage or an effective burndown and a pre-emergence residual herbicide application

Too many growers rely solely on post-emergence herbicides. Hitting weeds before they emerge and beginning a season with clean fields is paramount to keeping weeds at bay.

Use a two-pass pre- and post-emergence system

Two-pass systems ensure that you are addressing any and all weed presence. When applying herbicides, make certain that you are using the full recommended rate. Applying less than the recommended rate may contribute to resistance.

Employ multiple effective modes of action with overlapping efficacy

Herbicides with multiple effective modes of action are more difficult for weeds to resist. If you only use a single chemistry, you are unintentionally selecting for resistant weeds. By using mixtures with residuals, you can delay resistance issues.

Use a diversified management program

Beyond selecting the right herbicides, fighting weeds with other management approaches contributes to a well-rounded, full-farm approach. One management tactic instead of a combination of tactics is less likely to be effective on weeds, per the University of Minnesota Extension. Cover crops, mechanical weed control and crop rotation are great tools to ensure you are attacking weeds from all angles. It’s important not to overlook these traditional agronomic tactics.

Reduce the weed seed bank

Remember not to allow weeds to grow uncontrolled in the off-season. Eliminating seed production will halt the development of a weed seed bank on your farm. Even after harvest, weeds may continue producing seed until the first frost, affecting future seasons.

Keep an eye on the objective

Weed management and yield protection, not just weed control, is the objective. A clean field one day does not mean that you have defeated the enemy. Managing the weed seed bank and fighting resistance for future seasons will ultimately lead to the highest return on investment and yields.

To fight weeds in your fields this season, Syngenta offers BroadAxe^® XC and Boundary^® herbicides for early-season weed protection. Both of these pre-emergence herbicides provide two leading active ingredients with multiple modes of action and work well in a two-pass program. For comprehensive post-emergence control, Syngenta recommends Flexstar^® GT 3.5 herbicide. With two different modes of action, this herbicide enables you to fight weeds that are likely to develop resistance to glyphosate and/or ALS-inhibitors in glyphosate-tolerant soybeans. When it comes to weed resistance on your farm, it’s important to respect the strength of the enemy. Applying less than the recommended herbicide rate or not employing a thorough management plan against weeds may contribute to their resistance. Follow this guide to ensure that your fields don’t become the next safe haven for resistant weeds.

Think again before skipping fungicides in row crops

SyngentaAgronomy — Mon, 21 Mar 2016 20:02:13 +0000

Speculation about disease pressure, low commodity prices and the value of fungicides have been hot topics lately due to the heavy winter rainfall in the Midwest. With the increased rainfall and soaked fields, crops are at risk for diseases again in 2016. Fungicide treatments can protect against costly diseases; however, low commodity prices and increasing management costs may cause some growers to gamble with skipping one or more fungicide applications this season. Before taking that risk, growers should weigh the costs against the benefits. As we saw in 2015, fungicides can pay for themselves many times over by protecting against disease and helping to promote greater yields and profits. The University of Nebraska-Lincoln Extension lists several ways the use of a fungicide can likely increase profit margin:

Protection for susceptible hybrids
Support in cases of late planting
Prevention of early disease activity
Defense against weather conditions favorable to disease development
Promotion of high yield potentials

In addition, the extension estimated if fungicides cost an average of $15 to $20 per acre, an increase of 2 to 3 bushels per acre (bu/A) in yield will be necessary to cover the cost of each fungicide application. In recent trials, Trivapro™ fungicide showed a yield increase over untreated and competitive treatments ranging from:

+20-53 bu/A in corn¹
+4-8 bu/A in soybeans²
+13-28 bu/A in wheat³

With three active ingredients, including Solatenol^® fungicide, Trivapro provides preventive and curative control of diseases including rusts, leaf spots, Septoria and more. Even if growers’ fields don’t have a history of heavy disease pressure, Trivapro maximizes yield potential by promoting stronger stalks and bigger ears/fuller pods. With commodity prices as low as $3.66 corn and $9.18 soybeans according to USDA reports, this isn't the time to leave potential profit on the table.

Don’t let almond diseases get you down

SyngentaAgronomy — Mon, 21 Mar 2016 21:25:46 +0000

Thankfully, Mother Nature is providing almond orchards with some much-needed rainfall this year. While it is certainly wonderful to see rains return, it can also mean facing some disease challenges that underscore the importance of a strong fungicide program. University of California Cooperative Extension has already warned growers to prepare to prepare for diseases such as:

Brown rot
Shot-hole
Jacket rot
Anthracnose
Bacterial spot

Environmental conditions interact with both fungicide chemistries and pathogen physiologies. Wet weather can contribute to the spread of disease in various ways. To begin with, the window of fungicide activity is shortened during periods of consistent rainfall. Brown rot begins producing spores in late winter that can then be spread by rain splash in the spring. Extended wet periods increase both the spread and the intensity of shot-hole and warm, wet weather is ideal for the spread of anthracnose. Application timing and rotating modes of action are two of the most important aspects to consider in a fungicide program and Syngenta offers a wide-ranging portfolio and years of in-field expertise to help almond growers manage both of these considerations. So enjoy the plentiful rains, utilize the available fungicide tools for maximum effectiveness and grow more almonds.

The link between beet leafhoppers and curly top

SyngentaAgronomy — Tue, 22 Mar 2016 18:51:49 +0000

What exactly is the link between this pest and virus? The beet leafhopper favors dry, arid conditions and overwinters on weeds like wild mustard and Russian thistle before migrating to sugarbeet fields in the spring. Beet leafhopper feeding causes insignificant damage on its own, but is concerning because the insect can vector curly top virus. Beet leafhoppers can acquire the virus in as little as a few minutes of feeding and, for up to one month, can transmit the virus to other plants. Beet curly top is unique in that it is caused by a virus transmitted solely via the beet leafhopper. Controlling beet leafhopper is crucial to preventing curly top in sugarbeet crops. Controlling weeds and volunteer beets in areas surrounding sugarbeet fields can help reduce beet leafhoppers populations, and in turn help prevent curly top virus. Additionally, planting early and selecting tolerant varieties can help combat curly top. Using a seed treatment can also help protect sugarbeet plants from pests like beet leafhoppers. CruiserMaxx® Sugarbeets seed treatment insecticide/fungicide (combination of separately registered products) delivers consistent, long-lasting protection against early-season insects and diseases. A component of CruiserMaxx Sugarbeets, Cruiser^® 5FS seed treatment insecticide provides early season protection against injury from beet leafhopper which may spread curly top virus. Thiamethoxam, the active ingredient in Cruiser 5FS, can improve plant stands and help maximize yield potential, ultimately helping grow more sugar.

Stay ahead of corn diseases this season

SyngentaAgronomy — Tue, 22 Mar 2016 21:41:54 +0000

As commodity prices continue to drop, growers are looking for ways to save on production costs and maximize gains. So when deciding how to best manage the threat of key corn diseases such as Northern corn leaf blight (NCLB) and gray leaf spot (GLS), growers should carefully consider their management options. When deciding to purchase a foliar fungicide, scouting fields for diseases is normally the first course of action. But, research shows that disease spores could be affecting the yield potential of a crop long before this step is taken. According to researchers at the University of Kentucky, GLS infects the plant weeks before the first mature lesion appears. In fact, by the time a lesion is found, if the weather conditions are right, new spores may have already been released from the lesion and carried by wind, infecting nearby acres. Optimal growth and distribution conditions for GLS and NCLB:

Consistent winds and rain
Several days of relative high humidity and high temperatures (70-85°F) foster GLS growth
Moderate temperatures (64-80°F) and long periods of moisture on the ear leaf promote NCLB

Because of this timeframe and unseen infection, it’s important to know if your area is at risk for disease before scouting even begins. Understanding historical averages for disease in your area, past and future weather patterns, and the conditions that promote the spread of disease can help you stay ahead of costly, yield-robbing diseases. To help you assess the need for a fungicide before disease strikes, Syngenta has developed a prediction tool. This tool takes into account weather patterns, corn hybrid susceptibility and geographical location to predict the likelihood of GLS or NCLB in your area. This prediction tool is available to all Syngenta sales representatives and can help assess the chance for these diseases in your area. If you find your county has a moderate to high risk of GLS or NCLB, Syngenta offers Trivapro^™ fungicide to help protect your acres with preventive and curative activity on both GLS and NCLB as well as several other key diseases. Protecting crops with a fungicide that works as hard as you do is key to stay ahead of diseases and ultimately grow more.

Pre-planting preparations for optimal cotton stand establishment

SyngentaAgronomy — Wed, 23 Mar 2016 18:25:38 +0000

As cotton growers are preparing to plant, proper planning and management are necessary for optimal stand establishment. Poor soil temperatures and moisture levels, as well as heavy insect pressure, will adversely affect plant population, and ultimately crop yield and quality. Scouting cotton in the early stages of development can help identify fields where plants may be under adverse stress. While higher plant densities can help ensure a consistent stand, they can also lead to increased insect and disease pressure. The primary insect pest in the Mid-South and Southeast that threatens seedling cotton is thrips. Severe thrips infestations can cause stunting, maturity delays and yield losses. Because the severity of thrips cannot be predicted, insecticide seed treatments and foliar insecticide applications are recommended to reduce the risk of thrips damage. Targeting pests from emergence through the first weeks of development, seed treatment insecticides provide consistent and reliable protection against early-season insect pests under a variety of environmental conditions. Avicta^® Elite Cotton Plus with Vibrance^® nematicide/insecticide/fungicide, a combination of separately registered products, is a recommended seed treatment from Syngenta that will combat thrips and other insects, diseases and nematodes found in early-season cotton. The additional active ingredient to thiamethoxam allows cotton growers who have come to rely on Avicta® Complete Cotton, a combination of separately registered products, as their standard seed treatment solution to better combat early-season insects with increased product consistency. In addition, Syngenta highly recommends a foliar overspray of an insecticide with an alternate mode of action, from the neonicotinoid class of insecticides, at the one true leaf stage of cotton. Following these pre-planting tips, and preparing for the unexpected can help growers obtain optimal stand establishment, combat thrips and ultimately help grow more cotton.

Herbicide resistance: Be proactive, save money long-term

SyngentaAgronomy — Wed, 23 Mar 2016 21:54:12 +0000

Herbicide resistance continues to be a primary early-season concern of spring wheat growers. Over-reliance on herbicides, and the same mode of action, can contribute to the evolution of resistant weed populations. Resistance to herbicides leads to an increase in weed competition, as weeds are able to survive and reproduce even after being exposed to a herbicide that previously would have controlled them. Resistance typically goes unnoticed until at least 30 percent of weeds in a field are resistant. Once present in a field, resistance can persist and spread to other fields through movement of seed from resistant plants. To help combat herbicide resistance, Syngenta offers wheat herbicides with different modes of action like Axial® XL , Axial Star and Sierra^TM:

Axial XL helps control tough mixed grasses and maximize yield. With a wide application window, Axial XL offers the flexibility to apply early or late without sacrificing performance.
Axial Star serves as the foundation for an effective weed control program, helping growers simplify the complexity of weed management in spring wheat (excluding durum), winter wheat and barley. Axial Star will help manage tough weeds while providing crop rotation flexibility next season.
Sierra helps manage weed control in wheat by controlling the toughest weeds, providing a resistance management tool and offering customized weed control solutions. With its residual activity, Sierra can stop early-season weed competition and keep fields cleaner longer.

Sound resistance management practices help to keep resistance at bay while maintaining yields and minimizing costs. Be sure to rotate herbicides with different modes of action and chemical classes in successive growing seasons. If using a Group 1 herbicide like Axial XL or Axial Star, be sure to rotate with a Group 2 herbicide like Sierra. Always apply herbicides at the full, labeled rate and at the correct growth stage. This ensures the most effective control. Also be sure to incorporate other control tactics that fit the farm. Always clean tillage, seeding and harvest equipment when leaving fields that are infested with herbicide-resistant weeds. Regularly scout fields to identify and control weeds early and ultimately grow more wheat.

Protect your profits from SCN

SyngentaAgronomy — Fri, 25 Mar 2016 18:30:56 +0000

Imagine a thief that is virtually unseen by the naked eye. It slips into soybean crops through the soil, quietly releasing up to 250 eggs every generation that feed off of, and later tear through, soybean’s delicate root system. This pest not only plunders the health of crops, but a soybean cyst nematode (SCN) infestation can loot a hard-earned bottom line, too. Researchers with the University of Nebraska Extension say yield losses in soybeans due to SCN have been estimated at more than $1.5 to 2 billion in the U.S. Because the nematode may be present in fields without causing visible above-ground symptoms, damage is often underestimated. In fact, many producers suffer declining yields for several years while their SCN problem goes unnoticed. Sure, this puny pest is robbing from the industry, but how much damage can SCN do to an individual grower’s investment? A female SCN bursting with eggs SCN infected fields commonly experience annual yield losses of 5-15%, but reductions of more than 30 percent are possible, according to the University of Minnesota Extension. Without proper detection of and protection from this microscopic pest, negative yield and economic impacts will continue season-by-season. An annual yield loss of 30 percent is a big price to pay, especially since growers can identify SCN with yearly soil sampling and protect their crop with the right management strategy. To manage SCN and enhance yield potential in 2016, consider planting SCN-resistant NK® Soybean varieties treated with Clariva® Complete Beans seed treatment, a combination of separately registered products. Clariva Complete Beans is the only available nematicide seed treatment that protects soybeans from SCN all season long; this is crucial as SCN reproduces throughout the growing season. It also reduces the selection pressure that renders genetic resistance less effective, as well as reduces damage from SCN-related diseases such as sudden death syndrome (SDS). Clariva Complete Beans offers broad-spectrum, early-season disease and insect pest protection. Adding Mertect® 340-F fungicide to Clariva Complete Beans further increases the protection against SDS by adding a direct mode of action against the pathogen.

Pythium: The profit-munching pathogen

SyngentaAgronomy — Mon, 28 Mar 2016 14:50:26 +0000

In the animal kingdom, some predators prefer to prey on the weak. Similarly, in agriculture, soybeans are most vulnerable to predators when they’re young. Pythium, the fungal-like pathogen, can attack soybeans anytime but prefers to prey on the developing seedling. It can cause either pre-emergence or post-emergence damping-off, a disease resulting in the collapse and death of the developing seedling prior to stand establishment. There are several conditions that allow this unrelenting pathogen to creep through the soil and deal, sometimes fatal, blows to soybeans. Factors that increase the risk of Pythium include:

Early planting
Cooler soil temperatures
Saturated soils
Low-lying fields with poor drainage
Heavy, clay soils

Symptoms of Pythium can be spotted by scouting soybean fields from a week post planting through the V2 growth stage. Infected seedlings will have water-soaked lesions on the stems and roots. Established plants may not have soft roots, but they could appear yellow, stunted or wilted. The University of Nebraska-Lincoln Extension warns that in fields where early planting coincides with wet weather, Pythium will often show up. A seed treatment fungicide is recommended as the best management practice for fields susceptible to Pythium. CruiserMaxx^® Beans with Vibrance^® seed treatment, a combination of separately registered products, offers best-in-class protection for your fields. It uses its three fungicides to protect against widespread seedborne and soilborne diseases. In addition, CruiserMaxx Beans with Vibrance optimizes root health with efficient soil mobility and systemic movement throughout the plant. There are many advantages to planting soybeans early in the season, but the risks of heavy rainfall and cool soil temperatures should also be considered. CruiserMaxx Beans with Vibrance enables you to start strong so that your fields can reach their maximum yield potential, no matter the conditions. Don’t let Pythium nibble away at soybean plants. Protecting seeds and seedlings in the beginning helps reap the rewards at harvest.

Selecting the right soybean variety for season-long success

SyngentaAgronomy — Tue, 29 Mar 2016 14:27:36 +0000

Planting the right soybean variety has the potential to improve yields by as many as 20 bushels per acre, according to research from the Iowa State University Extension. So it should come as no surprise that experts with the University of Nebraska-Lincoln rank variety selection as the No. 1 most important management decision that influences soybean yields. When selecting soybean varieties, growers should look for the following:

Proven yield records: Select a high-yielding variety with proven performance in your region. It also helps to look at growing conditions similar to your fields, assessing multiple years’ results if possible.
Disease and pest packages: Research the disease and pest history of your fields before choosing which varieties to plant. Diseases and pests can greatly reduce yields, so pick varieties with genetic packages that match a field’s needs. Depending on the pest or disease concerns, look for varieties with good tolerance to soybean cyst nematode (SCN), sudden death syndrome (SDS), brown stem rot, iron deficiency chlorosis, Phytophthora root rot or other agronomic issues or concerns.
Range of maturities: Select maturities that match your growing conditions and that correspond with your region’s planting period. Also consider selecting varieties from a range of maturities to spread risk, stagger harvest and avoid loss due to shattering or poor harvest conditions.
Match your management practices: Some varieties are better adapted to certain management practices, such as irrigation, conservation tillage or narrow rows. Select varieties that will fit your management strategy as a whole.

Select varieties on a field-by-field basis. Assess each of the above characteristics and plant according to your specific growing conditions. Developed using the Syngenta Y.E.S. Yield Engineering System^™, NK^® Soybeans offer high-yielding varieties that integrate elite genetics and industry-leading traits. The Y.E.S. Yield Engineering System enables a faster breeding cycle for accelerated genetic gain, giving you faster access to new varieties.

Be alert for alfalfa weevils

SyngentaAgronomy — Wed, 30 Mar 2016 15:16:07 +0000

KENTUCKY: Winter temperatures have a significant impact on insect survival and pest activity for the upcoming growing season. The above-normal temperatures this winter favored key alfalfa pests, like the alfalfa weevil. According to the University of Kentucky College of Agriculture, Food and Environment, mild temperatures allowed female alfalfa weevils to be active and lay eggs on many winter days, potentially resulting in an early peak of larval feeding this spring. To protect crops, the University of Kentucky recommends the following:

Early field checks
Sample for alfalfa weevil
Choose a seed treatment with insect protection
Utilize insecticides

The longer a crop is under insect pressure, the more likely it is that yield potential will be affected. Protecting new seedlings with a seed treatment like CruiserMaxx® Alfalfa insecticide/fungicide seed treatment ensures a strong first line of defense against early-season diseases and insects. Additionally, utilizing an insecticide like Warrior II with Zeon Technology® helps ensure fast knockdown and long residual control of the most damaging insects, including alfalfa weevil. If harvest is delayed, an insecticide like Besiege® is recommended because it also provides residual control after cutting and during regrowth. Growers are encouraged to be proactive about scouting before and after cutting and to be timely with any treatment applications to help grow more alfalfa.

Preparing sugarbeet fields for success

SyngentaAgronomy — Thu, 31 Mar 2016 14:32:07 +0000

Properly preparing seedbeds can be the difference between strong and weak stands, which ultimately impacts sugar yield. Uncontrolled weeds can reduce sugarbeet yield by more than 90 percent. If a weed emerges and matures, it can contribute many seeds back into the soil seed bank. Depending on the weed species, seeds may be viable for many years:

Kochia is capable of producing 14,000 seeds per plant, although the seeds have a relatively short life in soil
Wild oat is capable of producing 60 to 200 seeds per plant which may remain viable for up to six years
Green foxtail is capable of producing 5,000 to 12,000 seeds per plant with some plants producing up to 34,000 seeds (depending on plant size)

In terms of herbicide resistance, the seeds that fall into the soil are the seeds capable of building a resistant population. To minimize the evolution of herbicide resistance, manage weed escapes and deplete next year’s weed seed bank by:

Starting with a clean field
Recognizing the lack of control early
Scouting early and often
Cleaning equipment
Varying weed control practices, including tillage
Not allowing weeds to reproduce by seed or proliferate vegetatively
Applying a preplant herbicide

Reduce the number of weeds in sugarbeet fields by applying an effective preplant herbicide like Touchdown® CT2 or Gramoxone® SL 2.0. Touchdown CT2 provides an alternative to tillage and delivers down-to-the-roots, systemic control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds. Gramoxone SL 2.0 herbicide delivers outstanding broad-spectrum contact control of the most difficult to control weeds in sugarbeet fields. Ensuring clean fields before planting begins can help provide a successful start to the season and ultimately help you grow more sugar.

Wheat growers: Have a proactive plan in 2016

SyngentaAgronomy — Fri, 01 Apr 2016 19:10:52 +0000

As spring wheat planting season approaches and winter wheat continues to break dormancy across the country, it is important to implement a proactive integrated crop management plan to ensure optimal stand establishment, protect against early-season weeds and diseases, and maintain wheat quality and yield potential. Syngenta offers the following tips and agronomic recommendations to help grow more profitable wheat in 2016:

Identify winterkill injury:With limited snow cover this season, the possibility of winterkill and poor wheat stands is a concern this spring. It’s important to identify winterkill damage and employ appropriate follow-up actions.
Evaluate the degree of winterkill injury: To manage the effects of winterkill, growers need to evaluate the degree of winterkill injury in their wheat and adjust next steps accordingly. Symptoms to observe include: plants with one or more dead leaves; patches of dead plants in the field; tiller development without accompanying root system growth; wilting, yellow and dying of some leaves after spring green-up.
Clear fields of residual weeds: It is important to establish a clean, weed-free field at least two weeks before planting wheat. If not, insects and diseases living in previous crop residue or remaining weeds can travel to newly emerging wheat and other spring crops. For optimum weed control, apply a quality burndown, pre-plant or pre-emergence herbicide, which delivers broad-spectrum control of broadleaf and grass weeds.
Scout early and often: Scouting early and at multiple stages of the growing season is important. Maintain consistent scouting practices throughout the season, and increase the frequency as needed during times of high pest pressure.
Make preventive fungicide applications: Considering the early widespread presence of rust this season, getting ahead with a fungicide application is particularly important. To help mitigate stress from diseases like stripe rust, use a preventive fungicide application.
Minimize crop stress, eliminate weed pests: Determining which weeds will make an appearance from year to year is difficult to predict. By monitoring their presence and making timely herbicide applications, growers can help maintain and improve their crops’ performance. Wheat growers can diversify their herbicide programs by using products containing different modes of action.

Following these steps, and being proactive can help growers get ahead of these problems and pests, ultimately helping them grow more profitable wheat.

Corn growers: Prepare for the toughest weeds

SyngentaAgronomy — Mon, 04 Apr 2016 14:37:11 +0000

Tough weeds are a constantly evolving challenge. Glyphosate weed resistance is expanding, and research shows infestations of tough broadleaf weeds in corn have gone up by 50 percent in the last four years.* Many other weed control programs have lost effectiveness, so it’s no surprise that four out of five farmers are actively seeking new products with the main reason to achieve better weed control.** The 2015 season brought significant weed concerns that have growers looking to achieve better control in 2016. Protecting yield potential with a high-performing residual corn herbicide allows growers to defend their investment. To put you back in control of tough weeds like giant ragweed, waterhemp and Palmer amaranth, Syngenta developed Acuron® corn herbicide, which delivers more residual control of more weeds with a single product than ever before.

Acuron provides more consistent, long-lasting residual control of tough broadleaf weeds and annual grasses, with 4 active ingredients (AIs), including bicyclopyrone, and 3 modes of action (MOAs).

Acuron Flexi corn herbicide, built on the foundation of Acuron, features 3 AIs and 2 MOAs to control tough weeds. Growers in certain areas of the Corn Belt will find Acuron Flexi especially appealing, since they are limited from using atrazine.

Bottom line: Weeds are an emotional and frustrating issue, but Acuron will put you back in control. Get the last laugh. Are you using Acuron or Acuron Flexi this season? We want to see.

Early-season burndown recommendations for corn and soybeans

SyngentaAgronomy — Tue, 05 Apr 2016 14:05:26 +0000

With the onset of warmer temperatures beginning early than normal this year, winter annuals and other early season weeds are coming out of dormancy and becoming more prevalent. If fall herbicides were not applied, early spring offers a good opportunity to stop these emerging weeds. Gramoxone® SL 2.0 herbicide is a great choice for quick burndown of these early season weeds. Gramoxone SL 2.0 provides a different mode of action to help manage glyphosate resistant weeds for resistance-conscious growers. This burndown tool works even in cool wet weather, is rainfast upon drying, and is an excellent choice when tank-mixing with other herbicides and fertilizers such as liquid nitrogen. Gramoxone SL 2.0 brings convenience, flexibility, and dependability for growers who want to get a head start on weed control.

Wheat winterkill worries with wavering weather

SyngentaAgronomy — Wed, 06 Apr 2016 16:13:31 +0000

This winter, wheat growing regions experienced inconsistent temperatures and sporadic snow cover. This prompted Syngenta and university extension agronomists to closely monitor the development of winter wheat crops as spring quickly approaches. Limited snow cover this past winter increases the possibility of winterkill and poor wheat stands this spring. Wheat growers are encouraged to identify winterkill damage and to then employ appropriate follow-up actions. Experts note that it is often difficult to distinguish between the damage from winterkill and damage from other potential problems, including snow mold, barley yellow dwarf virus, salt damage, frost injury or even Pythium. To manage the effects of winterkill, growers must evaluate the degree of winterkill injury in their wheat and adjust next steps accordingly. Symptoms to observe include:

Plants with one or more dead leaves
Patches of dead plants in the field
Tiller development without accompanying root system growth
Wilting, yellow and dying of some leaves after spring green-up

Growers are urged to wait until plants break dormancy and fields begin to green up before finalizing any replanting decisions. If you happen to have winter wheat, Syngenta agronomists recommend growers test for winterkill as soon as possible after a cold snap. This can be done within the comforts of their own home. To perform the Crown Viability Test, they recommend that growers:

Sample 20 to 50 wheat plants and clean them of soil and debris
Clip the top off of the plants to about an 1/8-inch
Clip the roots to about 1 inch
Place in a plastic bag and refrigerate overnight
Remove the plant from the refrigerator and monitor over the next 7 to 10 days. If the top shows growth, it survived – if not, it likely experienced winterkill

While peaks and valleys in temperatures and weather conditions can be concerning to wheat growers, patience and careful observation are essential. Before taking drastic action to address suspected winterkill this season, Syngenta cautions growers to carefully gauge the percentage of damage done (injury threshold); strategically select winter hardy varieties going into next season; and pick proper seeding dates based on region and weather conditions to maximize yield and quality potential. Syngenta also encourages growers to take a proactive management approach with their winter and spring wheat crops to capitalize on the profit potential these crops bring to their farms.

Soybeans: Top five weeds to prevent this season

SyngentaAgronomy — Thu, 07 Apr 2016 15:50:12 +0000

All weeds are problematic, but some can be worse than others. What are the top weeds soybean growers need to watch for this season? According to the University of Missouri Extension, these five can do the most damage:

Waterhemp
Marestail
Palmer amaranth
Giant ragweed
Italian ryegrass

These weeds are notorious for their ability to develop resistance to herbicides and evade herbicide control. To properly manage these weeds, a combination of pre-emergence and post-emergence herbicides is recommended, along with the use of row cultivation, according to Iowa State University weed scientists. An effective weed control program starts early. For control of stubborn weeds, Syngenta offers:

BroadAxe® XC herbicide for broad-spectrum, long-lasting residual control applied at preplant or pre-emergence. BroadAxe XC combines multiple modes of action to effectively control waterhemp, Palmer amaranth, foxtails, barnyardgrass and many other weeds.
Boundary^® 6.5 EC soil-applied herbicide to deliver proven early-season grass and broadleaf weed control, excellent resistance management and rotation flexibility. Containing two modes of action, Boundary 6.5 EC can extend your post-emergence application window up to five weeks after planting, thereby protecting your yields from weeds, keeping your fields cleaner longer.
Flexstar® GT 3.5 herbicide for a post-emergence, over-the-top application in glyphosate-tolerant soybeans. Flexstar GT 3.5 consists of two leading active ingredients and two different modes of action, providing fast, effective control of more than 50 broadleaf weeds, like waterhemp, Palmer amaranth, giant ragweed and morningglory.

Limiting weed pressure is the key to ensure plants continue to grow strong. Boundary, BroadAxe XC and Flexstar GT 3.5 eliminate weed competition. Offering multiple effective modes of action to control weeds, these brands, when combined with cultural practices such as crop rotation and tillage, help reduce the weed seed soil bank, maximize diversity and fight herbicide resistance.

Application flexibility matters for corn herbicides

SyngentaAgronomy — Fri, 08 Apr 2016 14:20:13 +0000

Even the best plans can be thwarted by bad weather. Wet and cold weather can make the corn herbicide application window smaller, and in many cases growers can completely miss it if the crop exceeds the planned herbicide’s application window. In 2015, extended periods of rain kept many growers from applying their herbicide at the intended timing. It’s important to have a herbicide that delivers flexibility and crop safety* regardless of weather conditions. The application flexibility Acuron® corn herbicide provides allows growers to apply their herbicide even with bad weather conditions. Acuron delivers broad-spectrum control of 70 plus tough broadleaf weeds and grasses, and can be applied 28 days pre-plant up to 12-inch corn. Additionally, Acuron Flexi corn herbicide is a new solution to control problem weeds, particularly in areas where atrazine use is limited. By allowing for application from 28 days pre-plant up to 30-inch corn, Acuron Flexi provides the flexibility growers need to best suit their fields. It’s important to be prepared for the unexpected. By selecting a herbicide with application flexibility, growers can worry less about adverse weather conditions and focus on growing more corn. Are you using Acuron or Acuron Flexi this season?

Not all corn herbicides are created equal

SyngentaAgronomy — Mon, 11 Apr 2016 17:11:20 +0000

When choosing the best herbicide to fit their farms, growers consider the spectrum of weed control, length of residual control and application flexibility. Broad-spectrum weed control Resistance to different modes of action is increasing, and multiple effective active ingredients are needed to target weeds that are resistant to common herbicide ingredients including glyphosate. Acuron® corn herbicide features four active ingredients – the newest active ingredient bicyclopyrone, as well as mesotrione, S-metolachlor and atrazine that work in tandem to deliver broad-spectrum weed control. When used in ALS-resistant fields, the weed control of Corvus® herbicide relies on a single active ingredient and control may be ineffective on weeds such as waterhemp and Palmer amaranth if conditions are not favorable to that ingredient. In SureStart® herbicide, acetochlor is a foundation rate (half of the original acetochlor rate) and is the only ingredient that provides significant control. Watch this playlist below to see how Acuron compares to competitive herbicide products in controlling tough weeds. Length of residual control Long-lasting residual control is also determined by a herbicide’s active ingredients. S-metolachlor in Acuron provides better, long-lasting and more consistent grass control compared to the grass components in Corvus and Verdict® herbicides. Application flexibility Corvus has a narrow application window up to V2 corn, while Verdict has an even smaller application window as a pre-emergence only herbicide. Compare herbicides, then decide With several weed management options available, consider the spectrum of weed control, residual control and application flexibility in current herbicides. Then ask yourself if your herbicide delivers what your field needs. Are you using Acuron or Acuron Flexi this season? We want to see.

El Niño effect on peanut crops

SyngentaAgronomy — Tue, 12 Apr 2016 14:10:56 +0000

SOUTH CAROLINA: With the heavy rain and wet weather conditions caused by the extended El Niño weather pattern this winter, growers are in a perfect storm for intense disease pressure. To give crops a fighting chance, proactive management will be more important than ever. Clemson University Extension outlines five key management practices for 2016 peanut production:

A well-drained soil
Suitable rotation crops – cotton, corn or other grasses
Water during pod fill
Good harvest weather
Timely management operations.

Early detection and identification of peanut diseases are critical in developing effective management solutions. Thorough scouting, and properly identifying diseases when they are easiest to control is key to choosing the most appropriate management tactics and crop protection products. Additionally, check with local university extension teams to see where disease outbreaks have been confirmed and utilize all resources available to help combat infection. Elatus^® fungicide improves disease control, maximizes yield potential and protects quality. With two active ingredients, Solatenol® fungicide and azoxystrobin, Elatus provides excellent control of various diseases, such as leaf spots, and provides excellent control of Southern stem rot caused by Sclerotium rolfsii to help producers grow more peanuts.

Wheat growers: How to manage herbicide-resistant weeds

SyngentaAgronomy — Thu, 14 Apr 2016 19:00:17 +0000

Application timing
Use of full labeled rates
Proper use of adjuvants
Effective spray application

Even when everything has seemingly been done right to protect wheat fields, growers still find areas where weeds have not been controlled. This lack of control could potentially mean a larger issue is developing: herbicide resistance. According to The International Survey of Herbicide Resistant Weeds, there are 14 herbicide-resistant broadleaf and grass weed species found in U.S. wheat crops today. Wheat growers have observed a particularly widespread occurrence of herbicide-resistant kochia and wild oat. Like other weeds, they compete with the crop for valuable sunlight, water and soil nutrients needed for robust development and strong yield. To stay ahead of this issue and retain maximum yield potential, Syngenta recommends growers consider the following proactive management techniques.

Manage weeds to prevent seed bank build-up
Utilize proper herbicide timing
Use the full, recommended herbicide rates
Diversify modes of action to reduce the risk of herbicide resistance
Diversify crops for future harvests

This spring, Syngenta recommends controlling weeds by making an effective herbicide application. Syngenta offers a robust portfolio of cereal herbicides offers growers multiple grass, broadleaf and cross-spectrum options with varying MOAs:

Axial® XL and Discover® NG herbicides for excellent control of grass weeds
Sierra™ and Axial Star for cross-spectrum options and the ability to tailor weed control programs to the specific spectrum in each field
Orion® herbicide is highly effective against yield robbing broadleaf weeds, and serves as an effective tank-mix partner with Axial brands for one-pass grass and broadleaf weed control

Pending registration for the 2017 growing season, Talinor™ herbicide will deliver excellent standalone control of resistant and other tough-to-control broadleaf weeds in barley, spring wheat (including durum) Utilizing multiple tools, and being proactive can help growers get ahead of weeds, which can help them grow more wheat.

Preparing for a successful cotton season

SyngentaAgronomy — Thu, 14 Apr 2016 20:46:17 +0000

Heavy rains across the Cotton Belt in February and March made it difficult for growers to plant corn on time, so many are making the switch to cotton this season. Successful cotton crops in the region over the last few years are also making cotton production a good solution for many, even with lower cotton prices. With planting quickly approaching, planning can make all the difference toward a successful season. Choosing the right variety sets the pace for a successful crop. It’s important to consider soil type, irrigation capabilities and management style when selecting varieties. The next step to a successful cotton crop is proactive management. Using a seed treatment like Avicta^® Elite Cotton Plus with Vibrance^® can help protect against early-season diseases, nematodes and difficult insects. An early foliar application of an insecticide with an alternate mode of action, from the neonicotinoid class of insecticides, at the one true leaf stage can also help. A proactive, season-long approach to weed management can help growers keep potential issues in check. With weeds exhibiting resistance to several chemistries, growers need to diversify their programs and include herbicides with different modes of action, like Dual Magnum^® and Caparol^®. Dual Magnum can be used pre-plant surface-applied, pre-plant incorporated or as a pre-emergence application, while Caparol provides foliar knockdown of emerged weeds and residual control of later-germinating weeds for even greater flexibility.

Strong sunflower stands lead to end-of-year success

SyngentaAgronomy — Fri, 15 Apr 2016 15:20:49 +0000

In sports, teams can often afford to lose the first few games of the year before turning things around and making the playoffs at season’s end. But producing sunflowers is almost the exact opposite. After a poor start to the season with weak stand establishment, there is little chance for a mid-season recovery and likely no cause for celebration at harvest. If growers want to maximize their sunflower yield potential, good stand establishment and plant spacing are critical. Uniform stands maximize sunlight exposure for production. If plants grow uniformly, they can better compete with weeds and form more consistent sized heads. The right management techniques and crop protection products can help ensure sunflower hybrids get off to a strong start and set the foundation for a prosperous season. While disease pathogens, insects, weeds and weather are ever-present threats, sunflower growers have access to an arsenal of crop protection products, technology and know-how to grow more sunflowers for positive results at harvest.

Quality hybrids: Strong stand establishment starts with thoughtful seed selection. It’s important to choose a hybrid with good vigor and resistance to downy mildew. Syngenta offers high quality sunflower hybrids, many of which include downy mildew resistance and NuSun^® oleic characteristics.

Seed treatments: While quality hybrid selection is an important first step in establishing a strong sunflower stand, seed treatments provide a defense against early-season disease and insect pests. To help sunflower plants start strong and defeat pests, CruiserMaxx^® Sunflower plus Bion^® insecticide/fungicide seed treatment, a combination of separately registered products, provides improved germination and emergence, promotes enhanced stand establishment and protects against all four classes of fungi.

Clean machines: To get the most out of quality hybrids, growers should properly maintain and calibrate planters and seed disks to establish good seed-to-soil contact – essential to the germination process. It important to use correct planting plates and make sure they are clean.

Straighten up rows with Unistand Unfortunately, all sunflower seeds are alike. Variance in size and shape can result in inaccurate planting depth and uneven rows. To help address these potential issues, Syngenta offers Unistand™ technology, an innovative sunflower pelleting technology available on select hybrids that consistently produces size 3 sunflower seeds. Because of this uniform seed size, Syngenta sunflower hybrids pelleted with Unistand plant more easily and won’t clog planters like traditional clay-based pellets. The improved plantability of sunflower seeds with Unistand also addresses a big threat to stand establishment – inconsistent spacing. Because of the uniform seed size, growers will experience increased singluation. Harvest yields are usually a reflection of the planning and work that happened at the beginning of the season. Through proper management techniques, sunflower growers who establish solid stands can celebrate a victory at the end of the year.

Pest Alert: Late blight found in SC tomatoes

SyngentaAgronomy — Mon, 18 Apr 2016 14:47:10 +0000

SOUTH CAROLINA: Late blight disease has been reported on tomatoes in Beaufort County. One of the most destructive and infectious diseases of tomatoes, late blight can cause total loss in tomato crops. The disease has been compared to ‘wildfire’ because of its rapid spread and destruction of the plants it infects. Spread of this disease to other areas of South Carolina is likely if late blight arrived from spores carried from Florida winds. Additionally, with the cool, wet weather South Carolina has experienced this year, this creates a perfect storm for the potential escalation of this disease. We’ve said before that prevention is key to disease control in tomato fields. To give crops a fighting chance, proactive management will be more important than ever. When checking fields for late blight, look out for these symptoms:

Large dark-green or gray spots on leaves surrounded by a lighter halo or ring
Spots are visible on both sides of the leaves
White-to-gray fungus growth development on the undersides of the leaves at the edges of the spots
Dark brown spots on the stems and petioles
Tomato fruit rot (blotchy and dark brown, but firm)

Clemson Cooperative Extension recommends that all growers carefully check tomato crops and — if the disease is discovered — treat them immediately. Growers along the coast should preemptively treat regardless. For effective control, Syngenta recommends Orondis Opti® fungicide in a season-long disease management program with other fungicides like Revus Top^®. Orondis^® Opti fungicide exhibits exceptional long-lasting disease control and systemic redistribution, bringing best-in-class protection against late blight in tomatoes. Combining the proven multi-site action of chlorothalonil, with the unique mode of action of oxathiapiprolin, Orondis Opti also offers built-in resistance management and can be included in a season-long disease control program.

Wheat growers: Prevent weed seed bank build-up

SyngentaAgronomy — Tue, 19 Apr 2016 15:38:33 +0000

We’ve said before that it’s critical to take a proactive approach to combat weeds, protect yields and fight herbicide resistance. It’s especially important to manage weeds to prevent seed bank build up. Weeds are often prolific seed producers, meaning that when weeds emerge and mature, they can develop and contribute seeds back into the soil, creating a large seed bank. Depending on the weed species, seeds may be viable for many years and can emerge when least expected. In terms of herbicide resistance, these are the seeds that are capable of building a resistant population. Limiting resistance starts with anticipating and recognizing the issue in the field by evaluating the plants that survive a herbicide application, and then managing those weed escapes to prevent an increase in next year’s weed seed bank. Take these steps to limit weed production:

Scout fields early and often to manage weed escapes
Identify weeds properly and select a product that addresses the weed spectrum
Clean equipment and machinery
Alternate tillage practices
Don’t allow weeds to reproduce
Apply an effective burndown herbicide like Gramoxone® SL 2.0

As the season progresses and crops mature, growers may begin to let their guard down. However, managing the seed bank is a year-round activity. Throughout the season, diligent record keeping, scouting fields, implementing agronomic practices and applying effective herbicides can all help grow more wheat.

Burning questions about burndown herbicides in corn

SyngentaAgronomy — Wed, 20 Apr 2016 14:34:31 +0000

There are currently lots of concerns and questions around burndown applications because there are lots of variables to take into consideration: weather, weeds present, cover crops, size of the weeds, intended crop to be planted, and timing, among others. Any plant present in a corn field should be considered a weed, and it’s never a good idea to let them get out of control.

What is the best option for terminating cover crops?

It is important to understand what is in the cover crop and then what is the best method. There are many good university publications on this topic. Purdue’s general guidelines can be found here with specifics about annual ryegrass here. Despite the overwhelming desire and interest to “plant into green,” it’s better to terminate weeds before they get too big. That being said it’s also better to wait until there are more consistent daytime temperatures in the 50s for translocated products to work. Gramoxone® SL 2.0 herbicide works better than glyphosate under cooler conditions. Best practices for Gramoxone SL 2.0 can be found here.

Can residual herbicides and burndowns be sprayed together?

A lot of factors go into this, especially planting timing. The earlier the residual application is made, the amount of days of residual left after planting may be decreased. When there is a cover crop or large amount of weeds present, it’s always a good idea to apply the burndown early with 2,4-D or Sharpen® herbicide and come back with residual herbicides close to or right after planting. When applications are combined later, soil and herbicide contact is compromised and small germinating weeds like marestail may not get covered under the taller weeds and cover crops.

Should you add anything to Acuron^®, Lexar^® EZ, or Lumax^® EZ herbicides in your no-till burndown?

These products are labeled on a number of winter annual and early emerging annual broadleaves. However it is recommended to add glyphosate or Gramoxone SL 2.0 to applications specifically when grass is present and weeds are greater than 3”. Specific technical recommendations can be found below:

These weed management options can help reduce the weed seed bank, maximize herbicide diversity and ultimately help grow more corn.

Plan ahead for weed control in almonds

SyngentaAgronomy — Thu, 21 Apr 2016 19:25:14 +0000

PACIFIC SOUTHWEST: Thanks to the high amount of rainfall this year, winter weeds are abundant in almond orchards. With moist soil conditions and warming temperatures nearing, summer weed growth is also expected to be high. Be ready to implement a summer weed control program. Weeds compete with almond trees for water and nutrients, which can be detrimental to an orchard. Scout orchards following a rain event, or watering, to see if new weeds are emerging. If so, identify the weeds present and apply appropriate herbicides to help control them. According to the University of California Extension, in order to ensure tree nut weed control efforts are as effective and as possible, consider the following before treating:

Make sure spray equipment is functioning properly
Select herbicides and rates based on specific weeds present or expected
Use spray nozzle tips, a spray pressure, and a travel speed that is adequate for the desired coverage of the herbicide type
Use drift-reducing spray tips and/or spray shields where possible to help mitigate spray drift concerns
Make sure post-emergence materials are applied to small weeds within 2-3 weeks after emergence

Broadworks™ herbicide provides residual control of broadleaf weeds and certain grasses for tree nut growers. By controlling weeds, such as marestail and fleabane, which are resistant to certain herbicides, including glyphosate, Broadworks aids in herbicide resistance management. It’s also important to rotate or tank-mix herbicides with different modes of action whenever possible to reduce the risk of herbicide-resistant weed development and preserve herbicide effectiveness. Broadworks is also an ideal tank-mix partner because its single active ingredient fits in well with other modes of action. To learn whether Broadworks is approved for use in your area, visit this page. For more information, talk to your local Syngenta representative.

Soybean root health should be top of mind

SyngentaAgronomy — Fri, 22 Apr 2016 15:45:53 +0000

Because roots are out of sight, they’re often out of mind. An estimated 80 percent of all plant struggles start with soil or root problems. Soilborne plant pathogens and below-ground insects threaten healthy root structures. On top of that, a crop with a damaged root system that’s under stress can have further difficulty taking up water and nutrients. The result is reduced plant growth, significant crop damage and yield loss. Because of this, it’s important for growers to take a proactive approach to producing soybean crops with stronger, healthier roots that lead to improved crop performance under a wide range of conditions. How? By choosing a seed treatment that can help enhance rooting power and protect the crop from pests. Visit the Syngenta Tools to Grow More Soybeans for more information about specific early-season pests. CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products, offers soybean growers a unique advantage through its ability to ensure optimal root health thanks to ideal soil mobility, long-lasting performance and superior disease protection. The Vibrance fungicide component optimizes root health through best-in-class Rhizoctonia protection and increases the potential for a larger root surface area with more root tips and forks to allow for more efficient water and nutrient uptake. As pictured, soybeans treated with CruiserMaxx Beans with Vibrance (right) showed larger root systems and better early growth and development compared to untreated soybeans (left). Stronger, healthier roots lead to increased productivity and nutrient uptake, ultimately helping to grow more soybeans.

Corn and soybean growers: Have a proactive post-emergence plan

SyngentaAgronomy — Mon, 25 Apr 2016 15:25:13 +0000

It might not look identical from state to state, town to town or even field to field, but weed pressure is everywhere. Growers can’t afford to let weed competition threaten yield potential - that’s why season-long weed management is essential. What to do? Weeds depend on routine to survive. Growers need to build diversity into their weed management programs to prevent further development of herbicide-resistant weeds. Weed management programs that rely on one herbicide increase the potential for herbicide-resistant weeds to develop. As a result, the herbicides used to control these weeds may become ineffective. Syngenta has a strong lineup of post-emergence corn and soybean herbicides:

Corn: Halex® GT herbicide tank-mixed with dicamba or atrazine helps maintain clean fields throughout the season. Halex GT can be applied as a post-emergence only treatment. Halex GT can also be used following Acuron^®, Lumax^® EZ or Lexar^® EZ herbicides for season-long control of annual grass and broadleaf weeds, helping your customers grow more corn.

Halex GT can be applied up to 30-inch corn, but when growers can apply Halex GT when weeds are under 4 inches tall, they can see a 12 bu/A yield advantage.

Soybeans: Flexstar® GT 3.5 herbicide offers post-emergence control of weeds that are difficult to control with glyphosate alone. Using Flexstar GT 3.5 after Boundary^® 6.5 EC or BroadAxe^® XC herbicides helps control stubborn weeds all season long.

Controlling weeds requires full-season attention. Growers who scout early and use multiple modes of action in their post-emergence herbicide program can prevent weeds overtaking their corn and soybean fields, fight resistance all season long and achieve higher yield.

Choose corn hybrids that can stand up to weather

SyngentaAgronomy — Tue, 26 Apr 2016 14:13:32 +0000

By now, most growers have an understanding of their fields’ pest threats and soil types, but one thing they don’t – and can’t – know is the weather that will hit them. Weather can throw a wrench in any well-devised plans, and given its unpredictability (not to mention the possibility of La Niña this year), growers should consider hybrids that perform well in a variety of conditions. Golden Harvest^® hybrid G01P52 brand has thrived in a variety of conditions in Iowa. Not only did G01P52 brand perform well in the warm, dry conditions of 2013, it also impressed during the cooler, wetter 2014 and 2015 seasons. Cool, wet seasons can increase disease pressure, but with Quilt Xcel^® fungicide applied at full tassel (VT), the corn again grew strong. It’s hybrids like G01P52 brand that can assure growers that regardless of the impact La Niña does or does not have this year, they are prepared. Of course, just as the weather is unique, each field is unique. Talk with your local Syngenta representative to discuss which hybrids are the best fit for your fields.

Defeating different diseases of grapes and berries

SyngentaAgronomy — Wed, 27 Apr 2016 14:37:22 +0000

Growers of small fruit like grapes and berries have many different diseases to watch for each season. Knowing which diseases are likely to happen in a given year can help growers make the right choices for preventive disease management strategies. The University of Kentucky Plant Disease Diagnostic Laboratories explains that disease presence last year can be a good indicator of risk for the same disease this year. The 2015 season showed that root/crown rot and leaf spot were most prevalent in berries, and grapes were hit by black rot and anthracnose. Blueberry growers can manage root rot and leaf spot with targeted fungicide applications. For root rot, a highly active soil-applied fungicide like Ridomil Gold^® SL can help control soil-borne diseases to promote root health and crop development. In lowbush blueberry production, an application of the next generation, long-lasting Aprovia^® fungicide in a non-cropping year can help with Septoria leaf spot and leaf rust. Aprovia is also a valuable tool for managing the most prevalent diseases in grapes. It delivers enhanced, broad-spectrum disease control with the power of Solatenol^® fungicide to inhibit infection and prevent the spread of existing disease, including anthracnose and black rot. For full management of black rot, Aprovia in rotation with Inspire Super^® fungicide is recommended.

3 tips for fighting herbicide resistance in wheat

SyngentaAgronomy — Thu, 28 Apr 2016 15:27:00 +0000

We’ve mentioned before that it’s important to prevent weed seed bank build up and make an effective herbicide application, but what else goes into fighting herbicide resistance? Syngenta outlines 3 important tips to help fight herbicide resistance:

It’s all about herbicide timing

Many variables impact herbicide application timing, including planting date, soil temperature, and amount of rainfall that occurs both before and after planting. By utilizing a post-emergence treatment, growers ensure overlapping coverage that keeps fields protected season long.

Full, recommended herbicide rates help delay onset of resistance

Help prolong the effectiveness of available herbicides and delay the onset of resistance in wheat fields by utilizing herbicides with different modes of action and using the full recommended rates.

Diversify modes of action to reduce the risk of herbicide resistance

In addition to using full rates, it’s also important to diversify herbicide modes of action (MOA). Syngenta offers a robust portfolio of cereal herbicides that include multiple grass, broadleaf and cross‐spectrum options with varying MOAs including:

Axial® XLand Discover® NG herbicides for excellent control of grass weeds
Sierra™and Axial Star for cross-spectrum options and the ability to tailor weed control programs to the specific spectrum in each field
Orion®herbicide for highly effective control against yield robbing broadleaf weeds, and an effective tank-mix partner with Axial brands for one-pass grass and broadleaf weed control

Pending registration for the 2017 growing season, Talinor™ herbicide will deliver excellent standalone control of resistant and other tough-to-control broadleaf weeds in barley, spring wheat (including durum). It contains the newest active ingredient in cereal herbicides, bicyclopyrone, combined with bromoxynil, to deliver excellent standalone control of resistant and other tough-to-control broadleaf weeds, including kochia and Russian thistle. Proactive practices can help minimize the evolution of herbicide resistance in wheat fields. Remember when applying herbicides that timing, using the full recommended rates and utilizing different MOAs will help fight herbicide resistance and ultimately grow more wheat.

Palmer amaranth: The weed of 2016

SyngentaAgronomy — Fri, 29 Apr 2016 13:54:39 +0000

A recent study from the Weed Science Society of America indicates that Palmer amaranth is the most difficult weed to control in the U.S. Although Palmer amaranth has not spread to the entire Midwest, it is likely coming. Two words come to mind when describing Palmer amaranth: aggressive and prolific. Often reaching up to 8 feet in height, this weed can grow up to 3 inches per day. In addition to its aggressive growth rate, some populations can quickly adapt to herbicides, leading to resistance. Its prolific seed production and germination throughout the season helps Palmer amaranth be more competitive than other pigweed species. Often producing tens of thousands of seeds per plant, Palmer amaranth grows quickly in open areas with full sun and undisturbed soils. An aggressive weed like Palmer amaranth must be met with an aggressive weed control strategy for growers to achieve high yields at the season’s end. Historically, growers have waited until post-emergence when the weed has reached its full growth, and then attacked with a post-emerge herbicide. This is often unsuccessful against an aggressive weed like Palmer amaranth. Palmer amaranth management tips:

Start clean with a full rate of a pre-emergence herbicide like Acuron® corn herbicide or Boundary® 6.5 EC soybean herbicide
Scout early and scout often so you can attack the weeds as early as possible
If necessary, follow up with a post-emergence corn herbicide like Halex® GT herbicide plus atrazine or a post-emergence herbicide with fomesafen, like Flexstar GT® 3.5 for soybeans
Maximize efficacy by spraying weeds before they exceed 3 inches

Palmer amaranth is known for its aggressiveness, but a strong weed control program equipped with herbicides containing multiple effective modes of action is the best approach to attacking this weed now and in the future.

Are adult stink bugs a concern for corn crops?

SyngentaAgronomy — Mon, 02 May 2016 16:04:37 +0000

The simple answer? Yes. Stink bugs overwinter in protected areas (field edges, crop residue, etc.) as adults. In early spring, they emerge to feed on weeds and crops, and lay eggs for future generations that will continue to build over the summer. No-till corn can be at significant risk due to the residue from last year’s crop which offers a great overwintering environment. Stink bugs feed on plant fluids by inserting their needle-like mouth parts into stems and leaves, and simultaneously inject materials into the plant to aid in digestion and sap removal. Severe suckering can cause significant damage to corn crops. Since symptoms start appearing a couple of weeks after the initial injury, it’s important to get in the fields early to check for adult stink bugs before the damage is done. Often times, stink bug damage can be confused with herbicide damage, since the bug has moved on from that spot. How should growers control this pest? Post-emergent applications of Warrior II with Zeon Technology^® insecticide are very effective. Warrior II with Zeon Technology delivers the combination of consistently reliable performance, modern formulation technology, and long residual for fast knockdown and residual control of the most damaging insects. As always, diligent scouting is very important and properly timed applications are necessary for control.

Protect corn yields from disease

SyngentaAgronomy — Tue, 03 May 2016 15:52:22 +0000

MIDWEST: With inoculum left in the soil and wet weather conditions this spring, disease outbreaks may be common again this season making conditions ripe for northern corn leaf blight (NCLB). Don’t let poor weather conditions be an excuse for poor yields. To give crops a fighting chance, proactive management will be more important than ever. According to Purdue University Extension, preventative management is especially important for fields at high risk for NCLB development. Be on the lookout for NCLB symptoms such as:

Long, narrow, tan lesions that form parallel to leaf margins
Long, oblong, or “cigarshaped” tan or grayish lesions
Large, irregular areas of dead tissue on the leaves

Use fungicides effectively We mentioned earlier that it’s important to use a flexible fungicide with good residual control in order to combat diseases. If your goal is to keep yields high and maximize profits, consider applying Trivapro™ fungicide. Trivapro:

Works harder and lasts longer than any other brand on the market
Helps produce corn with bigger ears, more kernels and stronger stalks for greater yield potential
Defends plants against multiple sources of stress and competition for improved crop enhancement
Helps shut down existing disease-causing pathogens and prevent future infections

Being proactive and applying fungicides will help growers get through the toughest years and ultimately grow more corn.

Protect lettuce from disease during wet weather

SyngentaAgronomy — Wed, 04 May 2016 15:00:49 +0000

With many cloudy, rainy days this spring, the pressure for disease development has been extremely high for lettuce crops. In lettuce, Pythium, Phytophthora, Rhizoctonia, Fusarium and Sclerotinia can cause major damage. These microbes favor wet soils and are often referred to as molds, rusts, rots and wilts. The roots and lower stems of plants they attack will exhibit signs of discoloration from yellow to brown and show symptoms of wilt which can cause plant decomposition. With a high chance of soilborne diseases so far, it’s important to stay ahead in the game. Syngenta recommends the following in order to combat diseases:

Variety tolerance/resistance
Fungicides
Good soil drainage
Crop rotation

Since weather is unpredictable, it’s important to be prepared for anything. In addition to offering a strong portfolio of lettuce varieties with resistance to diseases, Syngenta also offers Orondis® Ultra fungicide. Orondis Ultra is currently sold as a multi-pack product combining Orondis Ultra A and Orondis Ultra B and offers excellent control of diseases in lettuce. Orondis Ultra combines the active ingredients found in two products, Orondis and Revus® fungicides, to knock out diseases in lettuce and provide built-in resistance management.

Prevent citrus black spot this spring

SyngentaAgronomy — Thu, 05 May 2016 16:00:01 +0000

SOUTHWEST FLORIDA: Hidden from the headlines, citrus black spot (CBS), caused by Guignardia citricarpa, is back in the spotlight. Groves where CBS is present are subject to stringent guidelines that increase production and harvesting costs. CBS also renders fruit unfit for fresh market sale because of the symptomatic black lesions caused by the disease. These factors, along with reduced access to key export markets and the need for increased fungicide use, reduce the profitability of groves. Spread and management Citrus groves are most susceptible to infection April through September, when precipitation rates are at their highest. Because CBS is spread by windborne ascospores present in both fallen leaf litter and in existing fruit lesions on the trees, the University of Florida recommends preventative measures to help reduce the spread of the disease. Syngenta agronomists recommend that growers be proactive in making management decisions, and also:

Utilize regular fungicide applications beginning in April and continuing on 30-day intervals through September
Manage leaf litter in groves
Limit movement of infected leaf litter from one grove area to another
Remove weak or declining trees
Enhance air movement and leaf drying
Minimize dead wood in tree canopies
Source clean nursery stock
Sanitize equipment when moving fruit from one grove to another

For protection against CBS, growers can turn to Quadris Top® fungicide. The two active ingredients in Quadris Top, azoxystrobin and difenoconazole, are provide enhanced disease protection, while the two modes of action deliver resistance management benefits. Take control To optimize crop protection product performance and reduce the chances of resistance development, Syngenta agronomists suggest that growers:

Apply full rates of fungicides
Incorporate all proven effective modes of action
Use no more than two sequential applications of any mode of action
Incorporate other methods of disease suppression such as leaf litter management and increased airflow

A well-executed fungicide program, in conjunction with good cultural practices, can help Florida citrus growers reduce the spread of citrus black spot and decrease fruit drop. Incorporating these tactics into existing disease management programs will set growers up for a profitable season.

Take soybean disease control into overtime

SyngentaAgronomy — Mon, 09 May 2016 16:40:28 +0000

A lot of hard work and long hours go into having a successful soybean crop. From planting decisions, to herbicide and fungicide applications, the decisions growers make during the season can help soybeans yield strong. Fungicides create a protective layer against damaging fungi. According to the University of Wisconsin Extension, poor disease control can result from insufficient coverage, poor efficacy or resistance. For many, resistance to certain fungicide chemistries has become a rising concern. To minimize the risk of resistance, researchers with The Ohio State University Extension recommend the following strategies:

Practice integrated pest management practices: Scout fields for disease pressure and apply fungicides when the diseases are present or if there is a high risk for infection.
Rotate fungicide mixtures: Use different modes of action to help reduce selection pressure.
Follow label instructions: Carefully follow label instructions as some may limit applications due to product restrictions.

Trivapro™ fungicide combines three modes of action for the hardest-working, longest-lasting, broad-spectrum disease control on the market. The fungicide contains Solatenol^®, a breakthrough SDHI, that is 10 times more potent than any other SDHI on the market. Trivapro offers a step-change in preventive and curative disease control with three distinctly different modes of action, which greatly minimizes the potential for resistance development to soybean diseases including soybean rust and powdery mildew. This season, let Trivapro shoulder some of the work. Consider applying a fungicide, when necessary, to help maximize return on investment and ultimately help grow more soybeans.

Managing mites in walnuts

SyngentaAgronomy — Wed, 11 May 2016 15:48:12 +0000

PACIFIC SOUTHWEST: Small but mighty, mites can have a damaging effect on walnut crops. Feeding causes stippling and browning of the leaves, which can lead to leaf drop and ultimately reduce nut yield and quality. According to the University of California Cooperative Extension, managing mites in walnuts takes a sharp eye, monitoring, and predator awareness in the orchard. It’s also important to keep best orchard management practices to reduce populations such as:

Minimize dust by oiling orchard roads and maintaining ground cover
Keep orchards well irrigated – vigorous trees have reduced mite problems
When possible, avoid using pyrethroids, organophosphates, and carbamates until later in the season
Utilize a miticide, when necessary

Vegetable growers: 6 benefits of applying insecticides with drip chemigation

SyngentaAgronomy — Thu, 12 May 2016 15:13:55 +0000

Why should vegetable growers consider drip chemigation with insecticides? Drip chemigation has many advantages over traditional sprayers in vegetable production. Rutgers University Extension outlines six benefits below:

Total insecticide input is significantly reduced
Insecticides are quickly translocated throughout the plant
Weather is not a factor during application
Less energy is required to distribute insecticides
Applicator exposure to insecticides is significantly reduced
Fits well into an efficient and effective insect pest and soil management program

When applied through drip chemigation, Durivo^® insecticide ensures a quality harvest by providing systemic insect control with effective, long-lasting protection for 40 days or more. Durivo also:

Produces strong roots for better stand establishment
Provides broad-spectrum control of key lepidopteran, sucking and chewing insect pests
Results in more vigorous growth
Works systemically from within, reducing worker exposure to surface residues
Is readily taken up by the roots of germinating seeds and is rapidly transported throughout the plant

Utilizing insecticides and keeping best management practices can help protect vegetable crops. Consider using drip chemigation this growing season for more targeted insect control.

Reduce rice diseases in 2016

SyngentaAgronomy — Fri, 13 May 2016 17:00:19 +0000

Despite advances in rice production, diseases remain a major cause of yield loss in rice fields. Diseases reduce yield and quality, and ultimately increase production costs. The University of Arkansas Research & Extension says striking the right balance in disease management programs is key to reducing diseases in rice. When creating and implementing disease management programs, consider the following factors:

Matching varieties with fields
Balancing nutrients
Planting dates
Proper water management
Drain and dry strategies
Hydrogen sulfide toxicity
Field sizes
Fungicides, when necessary

Fungicide applications can be useful in well managed rice fields. Syngenta offers Quilt Xcel^® fungicide for long-lasting residual control of a broad spectrum of diseases. Quilt Xcel:

Contains the Power of Two™ active ingredients in a ratio designed specifically for rice growers
Offers exceptional convenience and ease of use
Provides curative and greater preventive disease control than products with only one mode of action

Evaluating your season-long sugarbeet Rhizoctonia management plan

SyngentaAgronomy — Mon, 16 May 2016 14:18:23 +0000

Last season, sugarbeet growers experienced significant disease pressure from one of the most destructive sugarbeet diseases – Rhizoctonia. This soilborne fungal disease causes significant yield loss by reducing tonnage and sugar content, as well as affecting quality in storage piles. Rhizoctonia can develop relatively early, and continue to develop throughout the entire growing season, depending on environmental conditions. The battle against Rhizoctonia can be fought with proactive and timely management practices. Syngenta recommends the following tips for this season:

Use tillage and fertilization to promote crop growth
Ensure adequate soil drainage
Make timely fungicide applications (early rather than late), particularly on susceptible varieties
Avoid cultivation that dumps soil into the crown of young plants

Experts at the Michigan State University Extension recommend using a T-band in-furrow and/or an early foliar-banded application of Quadris® fungicide in Rhizoctonia management plans. Quadris offers optimal disease control and allows crops to efficiently utilize resources like nutrients and water. Quadris also offers:

Application flexibility and long-lasting residual disease control
Slow but steady systemic mobility to ensure sufficient coverage and distribution within the plant
Excellent activity against Rhizoctonia

In addition to utilizing fungicides, Michigan State University Extension recommends growers evaluate every sugarbeet field for the inoculum level of Rhizoctonia. This helps determine the effectiveness of management plans and can help predict Rhizoctonia levels the next time beets are grown in that field. Choosing an early disease management plan, utilizing best agronomic practices and applying fungicides, when necessary, can help sugarbeets steer clear of Rhizoctonia and provide an increased chance for a successful season.

Manage tobacco transplant diseases to prevent yield loss

SyngentaAgronomy — Mon, 16 May 2016 15:26:46 +0000

KENTUCKY: With setting time quickly approaching, Kentucky growers should be mindful of troublesome diseases that travel with their tobacco transplants. According to the University of Kentucky, highly damaging blue mold and target spot are expected to be prevalent this year, which can cause significant yield losses in the field. Blue mold has already been identified as an issue this year in transplants from Georgia greenhouses. Since blue mold moves northward on weather patterns, growers should inspect their transplants closely for partially or fully necrotic leaves with darkened veins. A preventative Quadris^® fungicide application during transplant production or at first indication that blue mold is in the area can help manage the disease. Actigard^® 50WG fungicide can also help prevent blue mold once plants reach 12 to 18 inches in height. Target spot commonly affects transplants and lingers in the field, making it a threat from year to year. Transplants affected with target spot have small lesions with clear centers that expand as the leaves grow. A single application of Quadris during first or second clipping prior to transplanting can help prevent the spread of target spot. It’s important to be proactive when combating tobacco transplant diseases. Using fungicides, when necessary, can help maximize return on investment and protect tobacco crops.

Managing citrus greening

SyngentaAgronomy — Tue, 17 May 2016 14:39:03 +0000

Citrus greening, or Huanglongbing (HLB), is a systemic bacterial disease that has ravaged the citrus industries in India, China and Southeast Asia for decades and is now a major problem in Brazil and the United States. Currently, there is no cure, and citrus trees that contract the disease die in as little as five years. By the time it is properly diagnosed, the disease has often spread to many of the surrounding trees. HLB-infected citrus trees do not show symptoms during the first year of infection, so there is a long period of time when a grower cannot visually detect an infected tree — but the tree is still a source of bacteria that can spread to other trees via the Asian citrus psyllid. Controlling psyllids has become one of the primary strategies to prevent the spread of HLB. With no cure and no resistant citrus varieties available for HLB, certain strategies can still slow disease spread. These include planting disease-free nursery stock, removing infected trees, managing psyllids and promoting root health. After initial transmission in the shoots, the HLB pathogen infects roots. This infection causes rapid fibrous root loss of up to 40 percent before symptoms appear in the canopy. Studies show that roots infected with Phytophthora spp. may interact with the bacterial infection in roots, compounding root damage and loss. To reduce crop decline from this disease interaction, growers can implement a root health treatment program with Ridomil Gold® SL fungicide. Ridomil Gold has direct fungicidal activity against Phytophthora root rot disease. Roots rapidly absorb the fungicide, which is then translocated throughout the root system, promoting root health, crop development and enhancing your chance to grow more citrus.

Sunflower planting has started across the Northern Plains

SyngentaAgronomy — Tue, 17 May 2016 20:10:28 +0000

Planters are rolling across fields in the Northern Plains. According to the USDA, 21 percent of sunflower crops in North Dakota are already in the ground. The National Sunflower Association says growers are taking advantage of the good planting conditions by planting early to get the crop harvested as soon as possible and maximize return on investment. Before racing to the fields to plant, North Dakota State University outlines these main areas to consider:

Seed quality – Seeds should be uniformly sized to allow precision in planting. Sunflower hybrids with Unistand™ technology provide growers with easier, more accurate planting and improved crop emergence. Unistand always produces a size 3 seed that consistently delivers excellent singulation during planting.
Tillage – Tillage can be used to control weeds and incorporate herbicides in preparation for planting. BroadAxe^® XC herbicide provides broad-spectrum residual control of early-season weeds in sunflowers.
Seedbed preparation – Sunflowers require proper seedbed conditions to optimize stand establishment. Maintaining a moist seedbed is important if growers want uniform germination and emergence across the field.
Row spacing and plant population – Fields with a row spacing of less than 20 inches are considered to be solidly seeded. Equally spaced seeds can help produce a uniform sunflower stand, which helps maximize resources like water, nutrients and sunlight.

Errors made at planting can haunt growers throughout the season. Syngenta recommends using best agronomic practices and utilizing all the tools in a grower’s toolbox to help start strong, and ultimately grow more sunflowers.

Prevent disease by controlling whiteflies in melons and squash

SyngentaAgronomy — Wed, 18 May 2016 14:14:51 +0000

As the cucurbit growing season kicks into high-gear, so does the pressure from pests and diseases. A key to effectively minimizing disease pressure in melons and squash is to knock it out at the source. Whiteflies are a common pest and well-known carrier of detrimental crop diseases. Since 2004, whiteflies have been spreading a number of malicious viruses, such as squash vein yellowing virus, cucurbit leaf crumple virus, and cucurbit yellow stunting disorder virus, that are knocking out cucurbit crops, according to the University of Florida. Rather than waiting until the disease has already taken hold in your fields, Syngenta suggests addressing the carriers proactively with a mixture of control practices and insecticides:

Use proper crop rotation techniques
Ensure proper spacing between plants and rows
Implement insecticides with whitefly control into your IPM program

Syngenta offers the following insecticides to control whiteflies in melon and squash:

Soil-applied Durivo® insecticide, combining the active ingredients chlorantraniliprole and thiamethoxam, provides systemic insect control with effective, long-lasting protection for 40 days or more against whiteflies on melon and squash.
Foliar-applied Voliam Flexi® insecticide, containing chlorantraniliprole and thiamethoxam, is also an effective option for long-lasting residual control of sucking, chewing and lepidopteran pests, such as whiteflies.
Fulfill® insecticide also provides suppression of whiteflies through translaminar and locally systemic activity.

Implementing a comprehensive whitefly management plan can ultimately help lessen the potential spread of diseases in your crops. Contact your Syngenta sales representative for more information.

Pest Alert: Black cutworm found in Illinois corn

SyngentaAgronomy — Mon, 23 May 2016 15:11:54 +0000

ILLINOIS: Corn growers need to be on the lookout for black cutworms this spring. In some areas, black cutworms have already been observed. According to moth traps from the University of Illinois, black cutworm damage can likely become a problem in mid-May for growers in south central Illinois. This means growers could start seeing cut plants in their area soon. Syngenta advises that it’s important to scout fields frequently where corn is emerging. Signs of black cutworms include:

Leaf feeding
Cut plants
Wilted plants
Missing plants

One black cutworm larva can kill 4-5 plants, and with the cooler temperatures Illinois has been having, they can kill more. Black cutworms can destroy up to 10% of corn plants overnight. Utilizing an insecticide can help control black cutworm populations and help grow more corn. Warrior II with Zeon technology® insecticide delivers the combination of consistently reliable performance, modern formulation technology, and long residual insect protection. Zeon® Technology, a patented quick-release, micro-encapsulated formulation with a powerful UV blocker, ensures fast knockdown and residual control of the most damaging insects, including black cutworm.

Four tips to help improve corn growth during wet seasons

SyngentaAgronomy — Tue, 24 May 2016 14:00:37 +0000

Following lengthy periods of rain and frost in many Midwestern regions this spring, growers should be cautious of the effects that wet soil may have on their corn growth. Prolonged wet soil can cause difficulties like poor soil aeration, flooding and ponding, nitrogen loss for corn and soil compaction, all of which can reduce yield potential. Warmer, drier weather is the best remedy for wet or saturated soil, but Syngenta agronomists also recommend managing crops more carefully during wet periods to prevent loss in ROI during the season:

Cultivation during vegetative stages: Prior to “lay-by” once soil is dry enough, cultivation during the early- to mid-vegetative stages can help open up and aerate the surface layer and promote root growth.

Additional nitrogen applications: Growers should consider adding another application of nitrogen for corn where loss has occurred. Fields that show signs of yellowing with some uneven growth, but have a good chance to make grain and reach maturity, are the most qualified for an additional application. Agronomists recommend applying nitrogen to these fields as early as possible to gain the most benefit. Shortly after pollination is ideal.

Soil sampling: To determine whether additional nitrogen should be applied, growers should consider a late-spring test for soil nitrates before the rapid growth begins. When corn plants are six to twelve inches tall, soil samples should be taken and analyzed, assessing the plant available nitrogen.

General nitrogen application: If a test isn’t used, 40 to 50 units of nitrogen applied as anhydrous ammonia, liquid or urea with a urease inhibitor is a general recommendation. Rain shortly after application is helpful to move nitrogen into the root zone for uptake.

Beware of Asian soybean rust this season

SyngentaAgronomy — Wed, 25 May 2016 15:03:44 +0000

SOUTHEAST: Asian soybean rust has been found on kudzu in southwest Georgia. This is the earliest detection of this harmful disease in Georgia crops since 2005, according to the University of Georgia Extension. Younger beans are especially vulnerable to this disease. According to the USDA, be on the lookout for these symptoms:

Small lesions that increase in size and change from gray to tan, or a reddish brown
Lesions on the leaves, petioles, stems and pods

Syngenta recommends to continue to scout for Asian soybean rust as the season takes off. If growers suspect this disease might be present in their fields, experts suggest collecting samples and testing them as soon as possible. Additionally, utilizing fungicides can help combat this disease. When Brazilian soybean farmers were hit with an Asian soybean rust epidemic, Syngenta researchers developed Solatenol® fungicide for broad-spectrum, long-lasting disease control. In 2014, Elatus® fungicide, containing Solatenol, proved to effectively treat Asian soybean rust in Brazil. Figure 1. Untreated vs Solatenol (A17056A – 37.5 ga/ha) If Asian soybean rust is found this season, Syngenta recommends using Trivapro™ fungicide. Trivapro also contains Solatenol and is 10 times more potent than other SDHI’s on the market, delivering longer-lasting control and protection to crops. Utilizing best agronomic practices and fungicides, when necessary, can help combat Asian soybean rust and ultimately help grow more soybeans.

Don’t let post-emergence weeds decrease corn yield

SyngentaAgronomy — Thu, 26 May 2016 15:08:20 +0000

Studies have shown that yield losses in U.S. crops due to uncontrolled weeds exceed $20 billion annually.¹ As corn prices continue to fall, growers can’t afford to lose yield to pesky weeds and grasses in their corn fields. Syngenta recommends the following for best practices for herbicide applications:

Don’t ignore resistance problems: Use products with multiple, effective modes of action and overlapping residuals.
Avoid yield loss by starting and staying clean: Start clean by using a tillage pass or a burndown herbicide. For additional weed control a pre-plant, pre-plant incorporated or pre-emergence herbicide may be used.
Manage weed resistance with a post-emergence herbicide: Using a post-emergence herbicide with multiple modes of action and long-lasting residual can help manage weed resistance.

Solutions By combining three modes of action, Halex® GT herbicide makes weed resistance one less thing growers have to worry about. Experts recommend adding atrazine (e.g. AAtrex® 4L or AAtrex Nine-O® herbicides) to Halex GT when possible for an additional mode of action and synergistic weed control. This combination can be applied up to 12-inch corn. If atrazine cannot be used, add a dicamba product (e.g. NorthStar® herbicide). Weed management can make or break corn yields. When choosing weed management products for the 2016 growing season, consider a post-emergence herbicide application that can help save time and money by providing more effective weed control.

Pest Alert: Alfalfa weevils are emerging in North Dakota

SyngentaAgronomy — Thu, 26 May 2016 16:05:23 +0000

NORTH DAKOTA: Adult alfalfa weevils have been spotted. Alfalfa weevils are the primary defoliators of alfalfa. Eggs are laid in the alfalfa stems in the fall or spring by the adult female. When the eggs hatch, the larvae feed on the green plant tissue generally near the plant terminal early in the spring causing potentially fatal damage to alfalfa crops. Growers are encouraged to be proactive when scouting before and after cutting. North Dakota State University offers these detailed descriptions of alfalfa weevils: Adults:

¼ in. long and brown-golden
Blunt snout and dark brown longitudinal stripe in the center of the back
Antennae are elbowed and clubbed
Eggs are laid inside the stems of alfalfa, and are small and cream colored

Mature larvae:

⅜ in. long
Black head capsule and a green-wrinkled body
A white stripe, running lengthwise, can be observed across the top

Peak feeding occurs in mid-June, so Syngenta recommends being proactive and utilizing an insecticide like Warrior II with Zeon Technology® to help ensure fast knockdown and long residual control of the most damaging insects, including alfalfa weevil. Proper scouting and being timely with any treatment application is key to combating alfalfa weevils. Implementing these strategies can help maximize return on investment and grow more alfalfa.

Simplify soybean farming

SyngentaAgronomy — Tue, 31 May 2016 19:12:55 +0000

There’s a long to-do list when it comes to planting and protecting soybeans. From choosing the right seed and crop protection products, to perfectly timing planting and scouting fields, efficiency goes a long way to getting the most out of crops. One strategy to streamline this processes is with an insecticide-fungicide tank mix. Applying an insecticide-fungicide tank mix to soybeans is an effective way to cut down time and fuel investment, while boosting yields. A study from the University of Illinois indicated that using an insecticide-fungicide tank mix led to higher yields compared to a standard approach that included no crop protection treatments. Even during a year when drought likely limited insect and disease activity, applying a tank mix of an insecticide and a fungicide at the R3 growth stage resulted in average yield gains of 3.6 bushels per acre (bu/A). Syngenta field trials revealed an even stronger correlation of the benefits of tank mixing. Even under low disease pressure, Trivapro™ fungicide applied as a tank-mix with Endigo^® ZC insecticide to target both disease and insects provided an attractive return on investment for soybean growers. Utilizing a tank mix is a great way to save time and money. Increase soybean productivity and yield by applying a tank mix of Endigo ZC and Trivapro. Simplify, yield strong and grow more soybeans.

Don’t let downy mildew knock down sunflowers

SyngentaAgronomy — Thu, 02 Jun 2016 14:27:29 +0000

With the ability to wipe out large portions of sunflowers and significantly decrease yield, downy mildew is one of the most devastating diseases that can strike sunflower fields. However, by monitoring and proactively implementing the right cultural and chemical management practices, growers can preserve yields. Favoring cool, wet conditions, downy mildew is most prevalent in low-lying areas of sunflower fields with poor drainage, where water can pool and downy mildew spores can freely travel and infect large groups of plants. The disease spores enter the roots of sunflower plant and systemically invade it, causing severe stunting and often killing the plant. Downy mildew can occur in all sunflower-producing regions of the U.S. and is most common early in the season, right after planting. Symptoms and management: Downy mildew stays with its sunflower host until it reaches maturity, at which point it forms an overwintering structure that allows the pathogen to survive in soil for up to a decade. If infected plants are able to remain alive, they develop thick, yellow leaves and a white cotton-like substance appears on the underside of the leaves. Despite the potentially devastating effects of downy mildew, there are management options for controlling the disease before it can impact yields:

Monitor fields
Control wild and volunteer sunflower
Observe environmental conditions (cool temperatures, prolonged rainfall)
Plant downy mildew tolerant sunflower hybrids
Use a seed treatment that protects against downy mildew

Besides planting tolerant hybrids, growers can proactively protect against downy mildew by using seed treatments. A fungicide seed treatment is the only effective crop protection product for downy mildew control, providing additional protection for less tolerant hybrids and areas most at-risk for the disease. Because downy mildew is known to evolve and adapt quickly, Syngenta offers CruiserMaxx^® Sunflower plus Bion® seed treatment insecticide/fungicide for excellent insect and disease protection, increased germination and emergence, improved stand establishment and enhanced downy mildew protection. In addition to choosing the best-suited variety and seed treatment, be sure you are using the best protection methods for your field. In doing so, you’ll help ensure your sunflower crop gets off to a healthy start and remains competitive throughout the season.

Volunteer corn can be costly for soybeans

SyngentaAgronomy — Thu, 02 Jun 2016 16:39:08 +0000

Volunteer corn competes heavily with soybeans for water, nutrients and sunlight. University studies show that 2.4 volunteer corn plants per 100 sq. ft. can cause a 10% yield loss. If that’s not reason enough to target this weed, volunteer corn roots provide a food source for corn rootworm larvae. Remove the food source, and simultaneously eliminate any future eggs they might lay in soybean fields. For post-emergence weed control in soybeans, Syngenta offers Fusilade^® DX herbicide. This herbicide provides unmatched control of volunteer corn and plays a key role in controlling both annual and perennial grass. Additionally, by removing volunteer corn from soybean crops, Fusilade DX reduces the risk of developing corn rootworm trait resistance, which can lead to additional yield loss if not managed. Volunteer corn can lead to many other costly problems when not managed properly. Controlling this troublesome weed by using a herbicide enables soybeans to grow strong and reach their full yield potential.

Alert: EU’s view on peanut fungicides could change U.S. options

SyngentaAgronomy — Fri, 03 Jun 2016 14:25:48 +0000

According to Clemson University Extension, peanut foliar disease control programs in recent years have focused more heavily on late leaf spot because it consistently causes economic loss. Fields should be rotated out of peanuts for at least two years to reduce late leaf spot pressure, but even then the wind can carry spores for miles and place peanut fields at risk. Propiconazole is an active ingredient found in many peanut fungicides used to control late leaf spot. Unfortunately, the European Union (EU) will lower maximum residue limits (MRL) of propiconazole on Oct. 19, 2016 from 0.2 parts per million (ppm) to 0.01 ppm. Due to the lowered MRL, use of products containing it, including Tilt^® and Tilt® Bravo® SE fungicides, are in doubt for 2016. EU policymakers reevaluated the methodology used to determine the MRL for propiconazole, which resulted in the MRL changes. Until new data can be generated with the updated procedure to establish a reasonable new level, the MRL will remain at the default level of 0.01 ppm. There is a chance that the use of propiconazole at current labelled rates in the United States could result in residues above this very low MRL, potentially leading to the rejection of peanuts exported to the EU market. Syngenta is committed to taking the necessary steps to update the MRL for Tilt to meet the new EU requirements. To protect growers until the situation is resolved, Syngenta is advising against the use of propiconazole-containing products on peanuts for export. Propiconazole-containing products can be used on peanuts grown for seed, butter, oil or domestic consumption. In the meantime, what can be done about the threat of leaf spots? Growers can utilize alternatives to propiconazole on peanuts, such as Alto® (5.5 fl oz/A) + Bravo Weather Stik® (1 pt/A) fungicides.

Sugarbeet root maggot flies could come early this year

SyngentaAgronomy — Mon, 06 Jun 2016 14:18:26 +0000

RED RIVER VALLEY: Sugarbeet root maggots overwinter as full-grown larvae and rise to the surface as temperatures get warmer. According to North Dakota State University, the recent warm temperatures in the Red River Valley have likely accelerated the emergence of sugarbeet root maggot larvae. Experts recommend scouting for fly activity soon. Sugarbeet root maggots pupate close to the soil surface and the adult flies migrate to nearby sugarbeet fields, reproduce and deposit clusters of eggs near the plant. When the eggs hatch, the larvae feed on the sugarbeet roots. The full-grown larvae remain in the soil, overwintering for next season’s feed, and the cycle continues, making sugarbeet root maggots one of the most destructive pests growers face. Sugarbeet root maggots can cause:

Reduced plant stand and vigor
Surface scarring on the roots
Increased susceptibility to other root diseases

Cultural practices will not eliminate the problem, but can reduce the severity of the damage. Establishing a healthy, vigorous sugarbeet plant as early as possible is key to reducing sugarbeet root maggot damage. Starting strong with a seed treatment such as Cruiser® 5FS seed treatment insecticide and CruiserMaxx® Sugarbeets seed treatment insecticide/fungicide combination of separately registered products can help protect sugarbeet crops. Understanding the sugarbeet root maggot’s life cycle and utilizing insecticides, when necessary, is critical for managing this pest and ultimately protecting yields.

Three tips to improve weed resistance management in almonds

SyngentaAgronomy — Tue, 07 Jun 2016 14:27:49 +0000

This year’s wet winter amplified the growth of weeds in almond orchards, which also boosted the effectiveness of pre-emergent herbicides driven into the soil by the rain. Because of this, experts at the University of California Extension recommend a resistance management weed control program that combines pre- and post- emergent control for winter weeds and summer grasses. They recommend the following for managing herbicide resistant weeds:

Careful monitoring
Diligent record keeping in order to fully understand the history of the orchard
Rotating herbicide modes of action

To keep broadleaf weeds in check, Syngenta offers Broadworks^TM herbicide. Broadworks delivers enhanced pre- and post-emergence control through a mode of action that helps manage glyphosate-resistance broadleaf weeds, such as marestail and fleabane. Additionally, Broadworks enables flexibility when choosing tank-mix partners by fitting well in a mixture and rotation with other mode of action herbicides, allowing growers to build a strong, diverse weed control program. Broadworks herbicide is currently approved for use in most states. To learn whether Broadworks is approved for use in your area, visit this page.

Control citrus pests all season long

SyngentaAgronomy — Wed, 08 Jun 2016 17:22:24 +0000

CALIFORNIA: As the threat of spider mites in citrus crops begin to wane in June, the threats of the Asian citrus psyllid (ACP) and citrus leafminer are still very prevalent. In the San Joaquin Valley, California, the citrus leafminer typically starts to become active in early-June. It infests leaves and succulent shoots, often leaving young leaves damaged. To help growers identify the citrus leafminer, University of California, Davis outlines identification tips:

Pale or dark (excrement-filled) winding tunnels under the leaf surface
Distorted, galled, or rolled young leaves

ACP is a season-long, aphid-like insect that sucks phloem, distorting leaves and shoots while simultaneously spreading Huanglongbing, also known as citrus greening. Citrus greening attacks the tree’s vascular system and leads to decline in tree health and fruit production. Ultimately, it will kill the tree. As citrus greening continues its spread across California, it’s important to understand the danger ACP poses as a vector of this disease. It’s also important to follow proper techniques and application timings in efforts to manage ACP. Syngenta recommends the following:

Make ACP applications at beginning of new growth flushes
Use products or combinations of products (tank-mixes/pre-mixes) that also address other insect pests that may be present at time of application
Utilize an insecticide such as Agri-Flex^® insecticide, a pre-mix containing abamectin and thiamethoxam, that has activity against ACP and other pests

Sprayer skip highlights value of early-season weed control

SyngentaAgronomy — Thu, 09 Jun 2016 15:15:43 +0000

KANSAS: At first glance, sprayer skips are just an unfortunate mishap, but they can provide insights into the value of early-season weed control. Early-season waterhemp pressure resulting from a sprayer skip (left) vs. a pre-emergence application of Acuron® corn herbicide at 2.5 qt/A in a Sedgwick, Kansas field (right). Photos taken 27 days after application. The performance of a corn hybrid is heavily determined by when weeds are eliminated. Any weed that is present in the field when corn emerges has the potential to cause significant and permanent yield damage. Weeds exceeding two inches in height compete with the corn plant for essential resources (water, nutrients and sunlight). Therefore, early-season weed control with an effective pre-emergence herbicide is a vital part of yield protection. It’s more cost effective to prevent weeds from ever coming up than it is to fight them post emergence. Trying to control weeds after the fact forces growers to spend more money. It also places the corn in a situation where it has to metabolize additional herbicides when it’s trying to produce ears of corn. Using a pre-emergence herbicide such as Acuron can help with early-season control of waterhemp, morningglory and cocklebur. Cleaner fields reduce the chance of weed seeds being deposited into the weed seed bank, improve efficiency and leave time for other tasks. Are you using Acuron or Acuron Flexi this season?

Keep an eye on spring wheat crops

SyngentaAgronomy — Fri, 10 Jun 2016 16:01:36 +0000

Although weather conditions across the spring wheat growing region varied greatly this year, Syngenta suggests the same key management practice for all growers: start scouting and making proactive product applications now to prevent pest damage and mitigate environmental stress. As growers plan their scouting and fungicide applications this season, Syngenta recommends the following: Scout early and often Scouting is important at multiple stages of the growing season, and it’s best to start early. The first scouting trip should be to identify the pest species already present. If pests are present, think back to what was effective in past years. After initial product applications, remember to scout two to three weeks later to ensure good pest control. Maintain consistent scouting practices throughout the season, and increase the frequency as needed during times of high pest pressure. Make proactive product applications It’s important to get ahead of pests, especially with conditions as unpredictable as they’ve been in much of the country this year. Syngenta recommends that growers think of their fungicides like a shield, holding off pests before they arrive and helping to maintain – and improve – crops’ performance. Find what works best within the growing area, and stay ahead of disease and weed pressure. Keep a sharp eye out for resistance To be effective, document the presence of weed species, especially before and after product applications. Keep an eye out for dead weeds in close proximity to the same species of still-growing weeds – indicating a possibility of resistance. To best avoid this scenario, alternate product applications over time and strongly consider incorporating cultural practices such as tillage and crop rotation. As always, pests will be unpredictable from season to season but consistent scouting will be the key to a strong year. By staying ahead of disease and weed pressure with a strong management plan, you can increase your yield potential and grow more wheat.

Southern corn rust hits early this season

SyngentaAgronomy — Mon, 13 Jun 2016 18:44:20 +0000

GEORGIA: One of the most important and highly anticipated corn diseases this season, Southern corn rust has been found in Seminole County, Georgia. Dr. Bob Kemerait, pathologist with the University of Georgia Extension previously recommended growers hold off spraying fungicides until Southern corn rust was found. Now that it has been discovered, he encourages growers in the southwestern part of the state with corn near tasseling to apply fungicides for protection. Kemerait also encourages growers in other areas to monitor the spread of the disease. As growers continue to scout for diseases in corn, they should be aware of the following Southern corn rust symptoms reported by the Purdue University Extension:

Round pustules on the upper leaf surface
Orange to light brown spots

If above-average rainfall continues, Southern corn rust is likely to spread quickly, as it thrives in wet climates. For prevenive and curative protection against Southern corn rust and other key yield-robbing diseases, Syngenta offers Trivapro^® fungicide, available for the first time this season. Trivapro combines triazole, strobilurin and a SDHI component: Solatenol^®. This combination was designed specifically to maximize residual protection against rust. Southern corn rust: Untreated, Trivapro, Aproach® Prima, Stratego® YLD (from left). Utilizing fungicides before diseases like Southern corn rust begin to spread will help protect yield potential and maximize profit potential.

Sugarbeet growers: Be on the lookout for Pythium

SyngentaAgronomy — Wed, 15 Jun 2016 00:58:13 +0000

Hot conditions and excessive soil moisture creates a perfect environment for Pythium, a soilborne fungus that infects sugarbeets. One of the most common early season diseases, Pythium can infect seedlings and hinder stand establishment. However, it is also capable of damaging mature beets late in the season. Heavy infestations of Pythium significantly reduce sugar content and quality. Protecting sugarbeets from Pythium root rot starts before planting begins. To control Pythium root rot, growers can:

Provide ample field drainage
Prevent excessive moisture from irrigation systems
Use raised beds and sprinkler irrigation when excessive moisture is unavoidable
Rotate with non-susceptible crops

Syngenta offers CruiserMaxx® Sugarbeets insecticide/fungicide seed treatment to help protect sugarbeets against Pythium from the start. By protecting against both seedling diseases and insects, CruiserMaxx Sugarbeets enhances vigor, improves stand establishment, and helps grow more sugar by protecting the plant before the seed even germinates.

With heavy rainfall, continue to scout for soybean rust

SyngentaAgronomy — Wed, 15 Jun 2016 22:22:14 +0000

Due to recent periods of high rainfall, soybean rust continues to be a threat across the South. Soybean rust is able to spread rapidly during prime weather conditions, including extended periods of wet weather, moderate temperatures, and high humidity. According to Syngenta research, soybeans can experience severe defoliation in as little as five to seven days after the first exposure, with spores surviving 40 to 60 days. Soybean rust spores are spread by wind and can travel thousands of miles on southerly winds to the Midsouth and Midwest. The Economic Research Service of the USDA predicts that damage of this magnitude could cost U.S. soybean producers $240 million to $2 billion annually. In addition to the symptoms Syngenta outlined previously, also be on the lookout for:

Lesions that get progressively larger after about 9-14 days
Spore-producing pustules that appear on the underside of leaves
Leaves that drop prematurely, resulting in lower seed weights, fewer pods and fewer seeds
Symptoms that may superficially resemble lesions caused by other diseases, such as brown spot or bacterial blight. Note that soybean rust lesions have a powdery, granular appearance

Thankfully, fungicides sprayed at the earliest stages of disease development are extremely effective against soybean rust. Keep in mind that Syngenta offers Trivapro™ fungicide for growers looking for the most powerful, long-lasting preventive and curative activity against soybean rust. Trivapro helps shut down existing disease and prevents future infections. It helps crops to better achieve their full genetic yield potential by protecting against rust and drought stress, lengthening the pod fill window, and helping plants grow and reach canopy faster to help reduce weed pressure for maximum return on investment.

Start scouting for caterpillars earlier in soybeans

SyngentaAgronomy — Thu, 16 Jun 2016 22:16:23 +0000

The velvetbean caterpillar and green cloverworm caused significant soybean damage last year. Early signs indicate populations could be high again in 2016 due to mild winter conditions. According to Clemson University Cooperative Extension scouting typically begins in late July through August. However, this year’s mild winter could call for even earlier scouting, as pests may emerge sooner than last year. The University of Georgia Pest Management Handbook for 2016 recommends using an insecticide to protect against the velvetbean caterpillar and green cloverworm if 30 percent of defoliation loss has occurred and if larvae are at least half of an inch in size prior to bloom. The recommended sweep threshold is 38 larvae per 25 sweeps. When scouting for the velvetbean caterpillar and green cloverworm, keep the following in mind:

Defoliation will often appear at the upper part of the canopy
Green cloverworms are frequently misidentified and mistreated as soybean loopers
Velvetbean caterpillars range from green to dark black

Green cloverworm For protection against velvetbean caterpillars, green cloverworms and other key yield-robbing pests, Syngenta offers Besiege^® insecticide to provide quick knockdown and long-lasting residual control of the most difficult-to-control lepidopteran pests and other economically important pests. Applying these insecticides before caterpillars reach economic thresholds will protect yield and profit potential.

Hessian fly remains a threat to Southern wheat growers

SyngentaAgronomy — Mon, 20 Jun 2016 18:46:53 +0000

SOUTHERN GREAT PLAINS: Hessian fly continues to be a persistent threat to wheat growers in Oklahoma and Texas. According to Texas A&M AgriLife Extension, over 70 counties in Texas have reported Hessian fly infestations. Hessian fly can impact wheat yields through stunted tillers, lodging and even plant death in severe cases. The recent outbreaks of Hessian fly are likely due to mild winter conditions, which is ideal for high overwintering survival of Hessian fly. Additionally, the abundance of volunteer wheat due to high rainfall serves as a perfect host for these pests. During the larval stage, which usually occurs in the fall, maggots get underneath leaf sheathes near the crowns and feed on the plant by sucking the sap. This feeding process stunts the crop and subjects it to winter kill. To identify a Hessian fly problem, look for the following indicators:

Areas of poor stand or stunted plants after a frost
Eggs that are laid in lines of 10 or 12 in grooves on the upper side of leaves
Pupae that resemble flaxseed found by pulling back the sheaths of the leaves
Poorly filled heads causing lodged straw due to maggots in the late spring

A number of solutions can protect yields from the damages of Hessian fly. By planting a certified wheat seed variety with tolerance to Hessian fly, such as AgriPro® brand winter wheat variety SY Flint (new to growers for the 2016-2017 season), is one effective solution. Utilizing a seed treatment, such as CruiserMaxx® Vibrance® Cereals insecticide/fungicide, provides immediate protection against early-season insects and controls Hessian fly by killing the larvae that would feed on emerging plants. Be sure to regularly scout fields to track the presence of Hessian fly and other insect pests in your fields so you can continue to grow more wheat.

Solo-strobis slipping for soybean frogeye leaf spot control

SyngentaAgronomy — Tue, 21 Jun 2016 16:24:05 +0000

With 2016 soybean planting all but wrapped up, growers should begin to scout fields for pest pressure. Heavy disease pressure in 2015 followed by a mild winter can bring diseases like frogeye leaf spot into fields earlier this year. And, with the growing frequency of strobilurin-resistance, researchers recommend using fungicides with multiple modes of action to effectively manage frogeye leaf spot. Characteristics:

Appears as yellow-grey lesions with reddish-brown borders
Can result in premature defoliation, seed infestation and/or yield loss by as much as 30 percent

Best management practices:

Scout for the disease as plants approach reproduction
Apply a fungicide at the R3-R5 growth stage for the most consistent yield protection (under conditions of high disease pressure), according to The University of Tennessee
Use a fungicide with more than one mode of action to prevent or delay resistance

Multiple MOAs offer superior control Quadris Top^® SBX fungicide contains two active ingredients, azoxystrobin and difenoconazole, for superior disease control and resistance management. Independent trials from the Purdue University Extension showed that these two active ingredients offered the best control of frogeye leaf spot compared to the chemistries used by competitors. The pictures below from the 2012 fungicide efficacy trials in Valley View, AR tell the story. While some fields may have dodged frogeye leaf spot in the past, they are still susceptible to the important disease and its resistant strains. Staying vigilant and properly treating frogeye leaf spot with multiple modes of action can help save yield and manage resistance.

Fungicide application timing will make or break corn yield

SyngentaAgronomy — Wed, 22 Jun 2016 13:32:56 +0000

The success of this season’s corn yield could be contingent on whether or not growers choose to apply a fungicide at the R1 stage of development. Corn at the R1 stage is fully tasseled and beginning to green silk. The largest yield reduction occurs during this stage when corn is under stress. Applying a fungicide at this time can do more than just control disease; it can also help corn to:

Use water more efficiently
Preserve soil moister
Improve CO2 assimilation and nitrogen utilization
Extend the pollination window

Applying fungicide at the R1 stage will provide better disease control, protect stalk integrity, improve harvest efficiency and reduce volunteer corn in the crop to follow, each providing significant value to the grower’s bottom line.

One pass of Trivapro works harder than a two pass of Priaxor^® and Headline AMP^®.

For protection against disease and impacts of environmental stress at R1, Syngenta recommends using Trivapro^® fungicide. Trivapro combines triazole, strobilurin and a SDHI component: Solatenol^®. Trials have shown it has the longest residual control available on the market, and is both a preventive and curative option for disease. When applied during tassel/R1, Trivapro can increase corn yield by an average of 25 to 53 bushels per acre.[1] Applying a proven fungicide to corn at this crucial stage in development can improve yield potential and increase growers’ overall return on investment this season.

Potato seed treatments prove powerful against Rhizoctonia

SyngentaAgronomy — Thu, 23 Jun 2016 13:10:37 +0000

You may not be able to see what is lurking under the surface, but you can protect against it. Rhizoctonia overwinters in the soil waiting to infect potato crops. Once the plant is infected, Rhizoctonia can cause all sorts of grief: slowed emergence, reduced stand and/or weakened plants. As the disease progresses, it can stunt growth, cause the formation of aerial tubers and even turn leaves a purplish color. In recent trials at the Grow More Experience site in Ephrata, Washington, Syngenta potato seed treatments stood out in their ability to provide powerful protection against Rhizoctonia. As seen in the trials above, CruiserMaxx Potato and CruiserMaxx Potato Extreme seed treatments with Elatus fungicide provided excellent control of Rhizoctonia. With its two-prong attack against soilborne diseases, Elatus adds a preventative component to help stop Rhizoctonia before it becomes a problem, ultimately resulting in improved potato emergence, more uniform crop stand and enhanced crop health. Sign up for the Know More, Grow More Digest to receive twice monthly agronomic e-mail updates pertinent to your area. Growers should be aware that MRLs in export markets outside of North America are lower than those in the United States and may not be high enough to cover residue on all potato products. Prior to Elatus application, growers are advised to check with their potato buyer regarding Elatus use. Photos are either the property of Syngenta or used under agreement.

Soybean weed resistance management is spelled D-I-V-E-R-S-I-T-Y

SyngentaAgronomy — Fri, 24 Jun 2016 19:33:08 +0000

While limited acres of Roundup Ready 2 Xtend^™ soybeans have been planted this year, growers who want to plant this new technology in 2017 may be tempted to think this is the silver bullet for weed management. Though it will be another tool in the toolbox, growers have a lot to consider before making the switch. To help navigate those decisions, Syngenta recently held a resistance roundtable discussion with industry experts. Participating in the discussion were Stephen Powles, Ph.D., professor and director of the Australian Herbicide Resistance Initiative, University of Western Australia; Tim Hambrick, NC Cooperative Extension agent and 2014 Resistance Fighter of the Year; and Syngenta corn and soybean herbicide representatives. Top of mind for all participants was the importance of diversity in managing resistant weeds. Out of roughly 170 million acres of glyphosate-tolerant farmland in the U.S., 84 million acres currently contain glyphosate-resistant weeds. The development and spread of glyphosate-resistant weeds is expected to continue for the foreseeable future. This spread has increased herbicide spending 2 to 3 times for soybean growers since Roundup Ready^® technology was first introduced, said Powles. Growers are reminded that resistance management changes on a field-by-field basis, and a diverse herbicide program is the key to managing herbicide-resistant weeds and extending the life of herbicides that can be used with the new seed technologies, which are soon to be available. Best management practices include:

Deliver full labeled rates and apply herbicides at the correct growth stage
Invest in full-season weed control methods to prevent the establishment of weeds
Vary weed control methods, technologies and planted crops
Evolve your weed control techniques before weeds evolve resistance to your herbicide
Restrict buildup of the weed seed bank as a key way to minimize resistance
Scout before and after herbicide spraying to know what weeds you’re up against in each field
Integrate both pre- and post-emergence herbicides into your management plan
Tank mix with different modes of action and rotate different herbicides
Yanking weeds should be a last resort

Growers have to think about managing weed resistance today to ensure we have multiple herbicide options for the future. Diversifying weed management strategies can help ensure current herbicide technologies remain effective until new ones become available. Two critical components of a herbicide program, regardless of the trait platform, include the use of a pre-emergence herbicide with effective modes of action on target weeds and the use of overlapping residuals.

Be prepared to manage Cercospora leaf spot in sugarbeets

SyngentaAgronomy — Mon, 27 Jun 2016 18:51:12 +0000

It’s around that time of year again when sugarbeets get close to row closure, which also means it’s time to be on the lookout for Cercospora leaf spot. According to North Dakota State University, Cercospora leaf spot is the most destructive foliar disease of sugarbeet in North Dakota and Minnesota. Reductions in root size and sugar content are common in an infected crop, causing up to 40 percent yield reduction. How can sugarbeet growers protect their crops from this damaging disease? Syngenta recommends that growers get ahead of this diseases with a plan of attack. Most fungicides used for Cercospora control are protectant only, but a product like Inspire® XT fungicide, which contains two triazole fungicides, will protect sugarbeets from new infections and also cure those infections not yet showing spots on the beet. With current weather patterns there is potential for a worse than average year of Cercospora pressure, so make sure scout for Cercospora now to get ahead of this disease.

Effects of early-season drought stress on corn

SyngentaAgronomy — Tue, 28 Jun 2016 13:27:32 +0000

While some areas in the U.S. had adequate rainfall, others experienced hot, dry weather for most of June. Scattered rain and more rain chances in the future have brought some relief to the corn fields, but growers are wondering if the early-season heat and drought stress have affected the yield potential on their corn. Effects of drought on the corn plant

Leaves roll up. (Pictured above). Leaf rolling helps to conserve water by reducing the surface area of the leaf exposed to sunlight. This comes at a cost to the plant, however, as it will reduce photosynthesis, which in turn can affect the overall plant size and reduce yields.
Root growth is affected. Dry soils cause the root tips to desiccate and stop growing. It will also cause brace roots to grow along the surface instead of penetrating the dry soils, which can lead to standability issues later in the season. The decrease in root growth also limits the amount of root surface area that is available to collect nutrients and water from the soil solution. This can lead to a reduction in overall plant growth if conditions don’t improve.

Poor root development and brace roots growing on the soil surface due to dry soil conditions.

Reduced nutrient availability. Drought conditions reduce the soil moisture and available nutrients in the soil solution. Potassium (K) availability is reduced as the soil dries, and can become tied up in soils with heavier clay contents. Fields that have adequate K levels will help to increase the drought tolerance for the corn plants. K-deficient corn will compound the stresses brought on by drought.

Potassium deficiency in corn. Note the firing running down the leaf margins.

Early-season drought stress and yield potential Drought stress during the vegetative growth stages is generally less detrimental to yield than stress during pollinations and grain fill. That being said, it can still result in kernel loss and yield reduction, as there are important developmental processes taking place in the plants. Corn that is rolled up for a couple of days likely won’t see any significant yield loss, while corn that is rolled up most of the day for two weeks may see yield losses up to 20 percent. Actual yield reduction will vary greatly and depend on the severity and duration of the drought stress.

Three tips to control powdery mildew in grapes

SyngentaAgronomy — Wed, 29 Jun 2016 13:52:50 +0000

The rain this year was a welcome change from the dry growing season in 2016. But with wet weather comes a higher chance for grape diseases. Powdery mildew is a microscopic fungus that has the capability of devastating vineyards before you realize it’s even there. According to Oregon State University Extension, scouting for powdery mildew should be an important part of overall vineyard management plans. Finding the first occurrence of this disease can help growers know when to start or adjust fungicide programs and determine where to concentrate resources. There are several management practices used to manage powdery mildew, including:

Fungicide use. Rather than starting too early and wasting unnecessary applications, growers who frequently scout their vineyards can wait until disease is found and tailor a spray program to fit those needs.
Canopy management. Finding powdery mildew early can help growers focus limited resources where and when they are needed, and make timely adjustments in prebloom shoot thinning, sucker removal, shoot positioning, or fruit-zone leaf removal. Combining these practices can also reduce canopy density, allow better spray penetration, and increase air circulation, all of which propels management success.
Taking quick action. Under favorable conditions, powdery mildew may reproduce in as little as five days. Frequent scouting and quick management decisions, followed by timely action, are essential to combat this disease.

To enhance grape disease management programs, Syngenta offers Aprovia® fungicide for broad-spectrum disease control. With the power of one active ingredient, Solatenol® fungicide, Aprovia inhibits infection and helps prevent the spread of existing disease all while providing excellent control of powdery mildew at a low use rate. Aprovia also demonstrates excellent activity on many other diseases in grapes such as black rot and leaf spot. Aprovia fungicide is currently approved for use in most states.

Four Steps to Manage Glyphosate-Resistant Pigweed in Cotton

SyngentaAgronomy — Thu, 30 Jun 2016 17:18:59 +0000

TEXAS: Glyphosate-resistant pigweed currently infests a large portion of Texas cotton farms and is expected to spread across the majority of farms in the near future if proactive management strategies are not implemented. One female pigweed plant can produce over 500,000 seeds. That in itself is reason enough to take this problematic weed seriously, and glyphosate-resistant pigweed that is not managed properly will result in substantially more resistant weeds for following seasons. Texas A&M AgriLife Extension offers these best management strategies for preventing and managing glyphosate-resistant pigweed in Texas:

Start clean before planting – use burndown herbicides that do not contain glyphosate
Apply a preplant/pre-emergence herbicide
Utilize post-emergence weed management – assume you have or will have glyphosate-resistant pigweeds
Hand pull weeds

Texas A&M AgriLife Extension recommends that growers follow a minimum of three out of the four recommendations above to minimize the impact of glyphosate-resistant pigweed in cotton. Additionally, rotating herbicides with different modes of action is key to preventing and managing herbicide-resistant weeds. When appropriate, tillage is another good weed management strategy that will help reduce the risk of weed resistance. To help combat glyphosate-resistant pigweed in cotton, Syngenta offers Envoke® herbicide. Envoke effectively controls many troublesome weed species, including many of those missed by glyphosate. Envoke can be applied alone or in a tank mix over-the-top or post-directed for excellent post-emergence and residual activity in-season. Additionally, this herbicide can also be applied in the fall or early winter for pre-emergent residual control of glyphosate-resistant horseweed and tough winter annuals.

Tips for establishing pollinator habitats on farms

SyngentaAgronomy — Fri, 01 Jul 2016 17:42:19 +0000

With last week being National Pollinator Week, bees have been particularly top-of-mind for those of us in the ag industry. For me, pollinators are top-of-mind for another reason: my family recently planted an Operation Pollinator plot on our farm near Marshall, Minn. My family made the decision to establish a pollinator habitat for several reasons: bringing renewed purpose and vitality to previously unused land, introducing more color and beauty to the farmscape and, at the most basic level, attracting and providing food for bees and other pollinators that are so instrumental in helping various plants produce. Other wildlife also can benefit from the seeds that are dropped, feeding on the insects that are drawn to these areas. Working alongside colleagues who support Syngenta’s Operation Pollinator initiative helped solidify the decision. Operation Pollinator promotes adopting practical, cost-effective conservation practices, including planting region-specific seed mixtures, to help meet the needs of pollinators. Growers who may be interested in converting a portion of their land to pollinator habitats may find it helpful to evaluate the following attributes when deciding on a location for a plot. A few important considerations are outlined below.

Borders, hedgerows, grassy areas and buffer strips—land that won’t be disturbed by farming operations. It’s important to let neighbors and those with access to the land know where the habitat is located so it isn’t inadvertently mowed or sprayed.
Unused or marginal land—areas where input costs exceed production value.
Zero-to-low maintenance—areas with little weed pressure and where no-till practices can be implemented, as herbicides shouldn’t be applied and tillage should be avoided to accommodate ground-nesting pollinators.
Zero-to-little insecticide use—it’s critically important to ensure the plot isn’t near crops that will be treated with insecticides—other than targeted or timely sprays that can be applied safely.

It’s important to note that growers who establish or maintain pollinator habitats may be eligible for assistance or incentives from government conservation programs. Since requirements vary by state and county, growers should check with the appropriate state or local office of the Natural Resources Conservation Service (NRCS) or the Farm Service Agency (FSA) for information on these programs.

Pest Alert: Late Blight Found in Arkansas Tomato Crops

SyngentaAgronomy — Wed, 06 Jul 2016 13:25:55 +0000

ARKANSAS: Due to heavy spring rains, the fungal disease late blight has been found at a dramatically higher rate than usual per the Arkansas Cooperative Extension Service. One of the most destructive and infectious diseases of tomatoes, late blight can cause total loss in tomato crops. The disease has been compared to ‘wildfire’ because of its rapid spread and destruction of the plants it infects. Prevention is key to disease control in tomato fields. To give crops a fighting chance, proactive management will be more important than ever. When checking fields for late blight, look out for these symptoms:

Large dark-green or gray spots on leaves surrounded by a lighter halo or ring
Spots visible on both sides of the leaves
White-to-gray fungus growth development on the undersides of the leaves at the edges of the spots
Dark brown spots on the stems and petioles
Tomato fruit rot (blotchy and dark brown, but firm)

Arkansas Cooperative Extension recommends managing late blight by starting a fungicide spray program at planting. An application may also be able to stop the spread if symptoms are just beginning. For effective control, Syngenta recommends Orondis Opti® fungicide in a season-long disease management program with other fungicides like Revus Top^®. Orondis^® Opti fungicide exhibits long-lasting disease control and systemic redistribution, bringing protection against late blight in tomatoes. Combining the proven multi-site action of chlorothalonil, with the unique mode of action of oxathiapiprolin, Orondis Opti also offers built-in resistance management and can be included in a season-long disease control program.

Managing Two-Spotted Spider Mites on Soybeans

SyngentaAgronomy — Thu, 07 Jul 2016 14:45:35 +0000

Two-spotted spider mites feed by piercing soybean leaf cell walls and sucking out its contents. In doing so, the cells are left non-functional, which hinder plant growth and development. Worst of all, the damage is irreversible. According to Purdue University, a thorough scouting program will help control two-spotted spider mite populations. In order to identify and manage spider mites, Syngenta recommends these tips:

Utilize a paper test. Go to the suspected area and place a plain white sheet of paper along the plant on the ground. Shake the plant and leaves over the paper and wait a few seconds. When what looks like “dust particles” begin to move, it is most likely spider mites. Confirm this by using a hand lens and looking for two spots on the abdomen.
Be alert during hot and dry periods. Two-spotted spider mites become more of an issue in prolonged hot and dry periods. The damage of piercing leaves and feeding on plant juices adds to the plant stress. This also is why the plant symptoms may resemble leaf burning.
Continue to scout. Once mites are identified, it’s important to continue to scout in that area of the field every 5 to 10 days. Most spray treatments that are labeled for control of two-spotted spider mites have very short lived residual control and populations can spike very quickly even following an initial treatment.
Use proper rescue treatment timing. Prior to pod set, when 20-50 percent of the leaves are discolored. After pod set, when 10-15 percent of leaves are discolored. Take into consideration plant size, stress impact and short term weather forecast. Follow these technical recommendations for soybean spider mite control with Agri-Mek^® SC.

Don’t Let Palmer Amaranth Strangle Soybean Harvesting Efforts

SyngentaAgronomy — Thu, 07 Jul 2016 14:24:42 +0000

Palmer amaranth can reduce crop production and even hinder harvesting efforts due to rapid growth, aggressive competition, prolific seed production and germination throughout the season, according to the University of Arkansas Division of Agriculture. Because these pigweed species adapt quickly to new environments, some populations have acquired resistance to many herbicides, increasing the challenge of controlling glyphosate-resistant pigweed. Glyphosate-resistant Palmer amaranth can spread rapidly through almost any field if it’s able to get a foothold early in the season. The University of Arkansas Cooperative Extension recommends controlling Palmer amaranth by:

Utilizing a preplant or pre-emergence residual herbicide
Using good tillage practices to prepare the seedbed
Spraying Palmer amaranth when it is small (3 in. above the ground)

Syngenta solution For effective Palmer amaranth control in soybeans, Syngenta offers a variety of effective herbicides:

BroadAxe®XC herbicide controls Palmer amaranth and a full range of tough broadleaf and grass weeds through broad-spectrum, long-lasting residual control.
Boundary® soil-applied herbicide delivers early-season grass and broadleaf control, excellent resistance management and rotation flexibility. Containing two modes of action, Boundary can extend the post-emergence application window up to five weeks after planting, thereby protecting yield and keeping fields cleaner longer.
For full-season weed control in glyphosate-tolerant (GT) soybeans, Boundary and BroadAxe XC can be followed by a timely post-emergence application of Flexstar® GT 3.5 herbicide, which controls the same annual weeds as glyphosate, as well as several glyphosate- and ALS-resistant broadleaf weed biotypes, such as Palmer amaranth.

Boundary, BroadAxe XC and Flexstar GT 3.5 eliminate weed competition, while helping to sustain soybean technology. Offering multiple different modes of action to control weeds, these brands, when combined with cultural practices such as crop rotation and tillage, help reduce the weed seed soil bank, maximize diversity and fight herbicide resistance.

Reduce Vegetable Production Costs With Drip Irrigation

SyngentaAgronomy — Fri, 08 Jul 2016 14:12:03 +0000

Conserving water and reducing costs is always a priority for vegetable growers nationwide. Implementing drip irrigation is one way to conserve water for more sustainable production, according to Penn State University. Benefits As a University of Florida study explains, drip irrigation allows for a controlled application of water by allowing water to drip slowly near the plant roots through a network of valves, pipes, tubing, and emitters. And when properly managed, it can reduce labor and production costs and improve productivity, all benefiting the grower’s bottom line. Some advantages of a drip irrigation system include:

Requires half to a quarter of the volume of water required by comparable overhead irrigation systems
Allows for joint management of irrigation and fertilization
Doesn’t wet the row middles or the foliage of the crops like overhead irrigation, which helps reduce pest problems
Requires lower operating pressure than overhead irrigation
Can be managed and programmed with an AC- or battery-powered controller
Adaptable to oddly-shaped fields or those with uneven topography or soil texture, maximizing the use of available land
Enhances earliness and crop uniformity (when combined with raised beds, polyethylene mulch and transplants)

Best practices Experts at Penn State University provide a few tips on how growers can maximize their drip irrigation system:

Check filters daily and clean if necessary. A clogged screen filter can be cleaned with a stiff bristle brush or by soaking in water
Backwash sand filters to remove particulates and organic contaminants
Check drip lines for leakage. A large, wet area in the field indicates a leaking drip line. Leaking lines can be repaired by splicing with an inline connector or bypassed with a short piece of feeder tube
Use water treatment chemicals to dissolve excessive mineral deposits and remove buildup of organic contaminants in water supply lines

Pest Alert: Banded Sunflower Moths are Emerging

SyngentaAgronomy — Mon, 11 Jul 2016 14:17:01 +0000

NORTH DAKOTA: North Dakota State University (NDSU) reports that banded sunflower moths have been found in sunflower fields. Banded sunflower moths are a threat in all sunflower growing regions and are capable of reducing the number of seeds a sunflower produces. Be on the lookout for:

Inadequate pollination due to larvae feeding on florets and pollen
Silk-like webbing on sunflower heads (sign of feeding larvae)
Empty seeds from feeding larvae

In order to combat these pests, Syngenta recommends sampling for banded sunflower moths in the early morning or late evening, when they are most active. NDSU recommends egg scouting during the R3 crop stage and setting pheromone traps to see if these insects are present in fields. Additionally, utilizing insecticides such as Besiege®, Karate with Zeon Technology® or Warrior II with Zeon Technology® can help protect sunflower crops.

Pest Alert: Armyworm Damage Found in ND Wheat

SyngentaAgronomy — Tue, 12 Jul 2016 14:03:12 +0000

NORTH DAKOTA: North Dakota State University (NDSU) reported armyworm damage in wheat fields. Armyworms are a native species that overwinters in southern areas of the U.S. In the spring, the moths migrate to northern areas. These pests damage cereal grain crops by:

Feeding on leaf tissue from the ground up
Stripping off awns
Stripping off kernels

Large numbers of armyworm larvae can strip the plants of all leaf tissue. Grain fill, type of crop or variety, and weather conditions all influence the extent of yield loss. Syngenta recommends utilizing an insecticide to get ahead of these pests. Warrior II with Zeon Technology® insecticide delivers a combination of consistently reliable performance and long residual armyworm protection for wheat and barley. This insecticide also provides:

Quick knockdown and longer-lasting insect control
Reduced mixer loader and application exposure

In addition to utilizing insecticides, Syngenta also recommends to regularly scout fields to track the presence of armyworms. It is best to check fields in the evening or early morning, which is when larvae feed on plants. If there are five or more armyworms between 0.5 and 0.75 in. long/sq. ft., be sure to take action immediately.

How to Protect Sugarbeet Yield at Harvest

SyngentaAgronomy — Wed, 13 Jul 2016 13:34:10 +0000

Sugarbeet growers approaching harvest may ask themselves these two questions:

How can I protect sugarbeets to minimize loss in the pile?
How can I ensure that sugarbeet health and sugar content is maintained during defoliation?

Protecting roots at harvest Typical storage loss in conventional sugarbeet piles is about 1/2 lb. of sugar per ton of roots per day. Syngenta recommends the following in order to prevent storage loss:

Examine sugarbeets while harvesting and adjust accordingly
Avoid exposure to lifter wheels at harvest, which makes root tissue vulnerable to diseases
Avoid overly aggressive grab rolls and elevators during harvest
Arrange field ends so tractors and equipment don’t trample sugarbeet rows and damage roots
Use narrow tractor tires and keep them carefully between the rows

Proper defoliation Sugarbeets can be defoliated by flailing or scalping. The American Crystal Sugar Company offers these tips for proper defoliation:

Scalp sugarbeets with a uniform stand
Flail sugarbeets with uneven stands
Avoid overly aggressive defoliating
Protect cut sugarbeets from exposure
Keep defoliator speeds under 3 mph
Maintain cleanliness of harvest machinery
Control weeds for optimal defoliation
Don’t top sugarbeets too far ahead of harvesting

Soybean Solutions for a Season of Stinkbugs

SyngentaAgronomy — Thu, 14 Jul 2016 13:28:07 +0000

The stinkbug is one of the most common soybean insect pests in North America, according to the University of Missouri Extension. Soybean fields can quickly become the feeding ground for many different species of stinkbugs – the most common being the southern green stinkbug, the green stinkbug and the brown marmorated stinkbug. As reported by the University of Missouri, when stinkbugs invade a field, they primarily attack the pods and beans of the plant. Damage at these points can cause significant reduction to yield potential. Stinkbugs also remove fluids from soybean plants by feeding on the stems, foliage and blossoms. The stress of such an invasion causes leaves to curl and wrinkle as the life is sucked out of them, and some leaves may even express what is called “staygreen syndrome,” meaning they fail to mature naturally. Soybeans are particularly susceptible to yield loss caused by stinkbugs during the R4 to R7 reproductive stages. In addition, the piercing mouthparts of this insect leave wounds in the plant that can provide an avenue for diseases to gain entry into the pod. Syngenta recommends taking a proactive approach to control damaging soybean insects by utilizing an insecticide application such as Endigo® ZC insecticide. It’s also important to scout for insect pressures that have reached threshold levels. Scouting in these cases will help to identify where and when treatment is necessary.

Protect Corn Yield from Above-Ground Insects

SyngentaAgronomy — Fri, 15 Jul 2016 14:45:32 +0000

As corn reaches maturity, so does the in-field damage caused by above-ground insect pests, paving the way for economic losses. Because of their diversity and abundant numbers, they can be difficult to control, and can take a bite out of overall yield and grain quality. Controlling above-ground insects is a necessary step to help produce and harvest the “perfect ear” of corn. Part of the Agrisure® traits portfolio, the Agrisure Viptera® trait provides excellent, season-long control of key above-ground insects such as corn earworm, cutworm, armyworm and corn borer.

Soybean Seed Treatments Help Protect Against SCN

SyngentaAgronomy — Mon, 18 Jul 2016 14:25:20 +0000

Soybean cyst nematode (SCN) is the most damaging pest to soybean yields in the U.S. and costs growers an estimated 128 million bushels of soybeans every year, according to the University of Missouri Extension. For more than 20 years, SCN has mostly been managed through crop rotation practices and planting SCN-resistant varieties, however, SCN is increasingly less susceptible to genetic resistance. More than 95 percent of varieties use a single source of genetic resistance - PI88788. Overreliance has enabled SCN to adapt to this genetic resistance. Extension nematologists now recommend tools such as seed treatment nematicides in addition to traditional SCN management practices. Clariva® Complete Beans seed treatment, a combination of separately registered products, contains the only nematicide on the market that provides season-long, lethal activity against SCN and complements resistant varieties. Clariva Complete Beans also:

Delivers a yield increase of 2.7 bushels per acre (bu/A) compared to an insecticide/fungicide alone
Reduces the impact from sudden death syndrome (SDS) and other SCN-related diseases
Combines with Mertect® 340-F fungicide for increased activity against SDS
Reduces SCN reproduction and selection pressure
Optimizes root health and plant vigor
Increases yield potential at harvest

Help Corn Reach Its Ultimate Yield Potential

SyngentaAgronomy — Tue, 19 Jul 2016 13:16:44 +0000

MINNESOTA: As the demand for corn continues to rise, growers are constantly looking for ways to address these growing needs. One important way to meet this demand is to optimize corn yields through effective herbicide treatments. The performance of a corn hybrid is heavily determined by when weeds are eliminated. The earlier in the season weeds are removed, the more likely corn will reach its ultimate yield potential. Early-season weed management, along with season-long weed management, is essential to protecting the crop and capturing the highest value per acre at harvest. Syngenta agronomists recommend that herbicide choices should be made based on the targeted weed spectrum. Additionally, when choosing a herbicide program, growers should consider the driver weed species, like giant ragweed, in some areas. Syngenta stresses the importance of products with long-lasting residual and broad spectrum control. Growers in the Minnesota area have had good results with Acuron® or Acuron Flexi herbicides followed by Halex® GT herbicide. Acuron or Acuron Flexi applied in a split-shot (pre followed by post) application or followed by a post-emergence application of Halex GT* is an excellent two-pass program that provides:

Season-long residual control of a broad spectrum of the toughest weeds for maximum protection of corn yield potential and return on investment
Built-in weed resistance management. Acuron contains four active ingredients including, bicyclopyrone, and three modes of action while Acuron Flexi contains three active ingredients, including bicyclopyrone, and two modes of action. Halex GT contains three active ingredients and three modes of action and should be tank-mixed with atrazine or dicamba for resistance management purposes.
The strength of two powerful herbicides. Acuron and Acuron Flexi both deliver a step change in weed management with greater consistency of control and broader spectrum control on tough weeds. The number one post glyphosate premix in corn, Halex GT delivers burndown plus residual that works like a machine.

A critical step toward yield protection is effective weed management that begins early enough in the season to prevent economic yield loss. Some past research has focused on the impact weeds present in the field after corn emergence have had on yield. It is well documented that weeds exceeding two inches in height will compete with the corn plant for essential resources it needs to grow. Any weed present in the field when the corn plant emerges has potential to cause significant, permanent yield damage. Therefore, early-season weed control with an effective pre-emergence herbicide is a vital part of yield protection.

Pest Alert: Spider Mites in Michigan Soybeans

SyngentaAgronomy — Wed, 20 Jul 2016 12:41:48 +0000

MICHIGAN: For areas that have missed the rains, heat and drought are creating a perfect environment for spider mites in soybeans. According to the Michigan State University Extension, spider mites can be one of the most difficult pests to control. They feed with a piercing mouthpart, inserting it directly into plant cells and sucking out the contents. This type of feeding can injure or kill plant foliage, and also result in water loss through the feeding wounds. Syngenta recommends scouting dry soybean fields early and often, looking first on the borders of the fields for soybean plants that start to turn bronze or brown in color. Additionally, utilizing paper tests can help spot these tiny pests. Shake plants from the area of concern over a white piece of paper. If small, yellow dots collect on the paper, and they start to move, they are probably spider mites. If dry weather persists, Syngenta recommends to spray immediately – before the spider mites spread to the rest of the field. Utilizing a miticide/insecticide such as Agri-Mek^® SC helps protect soybean yield that may be vulnerable to damaging mites and insects.

Agronomic Updates from Hawkeye/Cyclone Territory

SyngentaAgronomy — Thu, 21 Jul 2016 14:51:34 +0000

Iowa corn and soybean growers should be proud of harvesting a colossal 23 million acres statewide in 2015 – whether Hawkeye or Cyclone fans. Every acre makes a difference in feeding and fueling our growing global population, and 17 acres are set aside in Carroll, IA, this year for education. While conquering weeds, diseases and insects remains at the forefront of the education conversation at the Carroll Grow More™ Experience site, a fourth environmental factor became a topic of focus: pH levels. Many Iowa growers are cutting back on lime applications, unaware their pH levels are falling to yield-blowing lows. The ideal pH level ranges from 6-7, so if needed, add lime to bring the pH back up to that level. Nitrogen, phosphorous and potassium may be plentiful in a low pH soil, but not able to be taken up as efficiently. Adding 10 pounds of sulfur per acre can increase yields 10-40 bushels in sulfur deficient fields. To see if corn and soybean fields need a pH or sulfur boost next season, conduct fertility tests. Dealing with Weather Woes While Iowa growers are most likely all-too-well aware of the 70+ mph winds that have ripped across the state, there are ways to minimize Mother Nature’s force. Planting depth is an especially important consideration when it comes to wind. Seed planted 1.5 inches deep versus 0.5 inches will stand a much greater chance of overcoming root lodging. Considering the rainfall, humidity, and dew levels many Iowa growers have seen this season, keep an extra eye out for Northern corn leaf blight (pictured above), gray leaf spot, and eyespot in corn. Southern rust has also been working its way north and is catching many growers unaware. In soybeans, brown spot and frogeye leaf spot are becoming more prevalent. These diseases can be controlled with an application of Trivapro® fungicide. Along with scouting now, take a look at the disease pressure ratings of your hybrids and varieties. Since there are no industry standards, be sure to talk with your local agronomists to stay ahead of diseases. For next season, try to plant as early as possible so there is less time for disease inoculum to accumulate.

Phytophthora Root Rot: A Threat to Soybeans

SyngentaAgronomy — Mon, 25 Jul 2016 14:49:22 +0000

In the midst of a warm and wet summer, soybean growers should plan to keep an eye out for Phytophthora root rot. A fungal disease most common in fields with saturated soils, Phytophthora root rot can cause wilting or even death of crops late in the season. Syngenta agronomists recommend that growers scout their fields and watch for the following symptoms of Phytophthora if their region has undergone excessive wet weather:

Crop discoloration: According to the Purdue University Extension, growers will usually notice dark brown discoloration of the stem and lower branches during the stem rot phase of Phytophthora. In more mature crops, watch for yellow or white leaves.
Stand problems: Stand issues or a lack of emergence might also be an indicator of the disease early in the season. If stand establishment is problematic, growers should plan to dig up the seed and check for seed rot.

CruiserMaxx® Beans with Vibrance seed treatment, a combination of separately registered products, provides a broad range of protection against early-season soybean pests. CruiserMaxx Beans with Vibrance delivers systemic root protection against certain seedborne, soilborne and foliar diseases, including Phytophthora root rot.

Get a Leg Up on Peanut Late Leaf Spot

SyngentaAgronomy — Tue, 26 Jul 2016 15:42:18 +0000

Late leaf spot is one of the most aggressive and difficult to control peanut diseases. This fungal pathogen attacks any above-ground portion of the plant, leaving brown to black spots on the upper leaf surface. Leaf spots are the most conspicuous symptom, however. According to the University of Oklahoma Extension, be on the lookout for these symptoms:

Brown to black, pinpoint-size dots on the upper leaf surface
Black, circular spots with a less pronounced yellow halo
Spots that reach about 1/4 in. in diameter
Clearly defined spots on the lower leaf surface
Pale green to yellow leaves that wither and fall off the plant
Defoliation on lower leaves that progresses upward
Dark brown to black, oval-shaped lesions on stems, petioles and pegs

Controlling leaf spot is critical to prevent heavy defoliation and yield loss. Experts recommend using an integrated management program that combines the following:

Cultural practices. Rotation of peanuts with other crops and management of peanut residue by tillage can help delay the development of disease. Proper irrigation also helps reduce leaf spot.
Genetic resistance. Peanut varieties differ in reaction to leaf spot, but levels of resistance in peanut varieties alone are not sufficient to provide adequate disease control.
Fungicides. A fungicide program is normally required to prevent yield loss from leaf spot. Elatus^® fungicide provides excellent control of foliar and soilborne diseases in peanuts. With two active ingredients, Solatenol® fungicide and azoxystrobin, Elatus provides improved control of Rhizoctonia (stem canker), early leaf spot, late leaf spot, Southern stem rot (white mold) and rust.

Common Ragweed Pays Soybeans an Unwelcomed Visit

SyngentaAgronomy — Wed, 27 Jul 2016 14:26:10 +0000

It’s that time of year again – when the unwanted common ragweed can make an appearance in soybean fields at a crucial stage of development. This difficult summer weed is known for causing damage to soybeans, corn and other crops each growing season. Once rooted, ragweed can grow up to 6 feet tall with a span of 4 inches across. Michigan State University research has shown a yield decrease up to 30 percent at a density of just two plants per 10 feet of row. With the development of herbicide resistance in ragweed species, growers may see weed escapes later in the season despite a pre-emergence application. At this point in the season, soybean growers can’t afford to let ragweed take over. Right now, growers should be focusing on post-emergence applications to control ragweed if they see weed escapes in their fields. Syngenta offers Flexstar^® GT 3.5 herbicide as a post-emergence option to help protect weeds that are difficult to manage with glyphosate alone or are resistant to glyphosate and ALS-inhibitors. It contains two leading active ingredients, glyphosate and fomesafen, delivering two different modes of action. Flexstar GT 3.5 provides sustainable control of tough weeds throughout the growing season. A two-pass program, consisting of pre- and post-emergence herbicides, offers the most thorough weed management strategy. Taking proactive measures and monitoring treatments throughout the season can help maximize yield and profit potential. Learn more about common ragweed management to help your soybeans grow strong.

Rice Stinkbugs Are on the Rise in Arkansas

SyngentaAgronomy — Thu, 28 Jul 2016 15:36:30 +0000

According to Dr. Gus Lorenz, University of Arkansas extension entomologist, rice stinkbug levels are high across the state, especially in the Arkansas River Valley. The rice stink bug, or Oebalus pugnax, does not usually appear in rice fields until heading has begun. The adult pests insert their mouthpieces into the developing seed and inject secretions into the plant. The hardening saliva creates a feed sheath around the plant, which can result in quality and yield loss. Fortunately, the arsenal of insecticidal tools available to growers includes Karate with Zeon Technology®, a foliar-applied residual insecticide that offers long-lasting, broad-spectrum control of primary and secondary chewing and sucking insects. Karate with Zeon Technology provides residual activity, consistency, flexibility and value. Product benefits include:

Quick release capsules that provide fast knockdown of target pests
Improved rainfastness resulting in better overall control
Broad crop label with versatile tank mix and chemigation compatibility

Compaction, Dry Weather a Bad Mix for Water Uptake

SyngentaAgronomy — Fri, 29 Jul 2016 17:29:55 +0000

Growers in regions that have seen little to no rainfall this season should be mindful of dry weather exaggerating the effect of soil compaction in their fields. Dry weather stresses a plant’s ability to take up water, and if the plant root is already struggling to grow through hard, compacted soil, it makes access to water that much more difficult. Uneven crop canopies are typically a tell-tale sign of soil compaction. To see if fields are impacted by compaction, Syngenta agronomists recommend that growers take a shovel to the soil of crops that appear to be drought-stressed. When shoveling, look to find the dense, compacted layer just below the tillage depth. This will confirm whether a field has soil compaction or not. If growers come across soil compaction in their fields, agronomists recommend the following management options to prevent loss of yield potential:

Deeper tillage, but only if the soil is dry enough to allow it
Adjust planter/make planter modifications

The Link between Sunflower Planting Mistakes and Harvest Nightmares

SyngentaAgronomy — Mon, 01 Aug 2016 15:14:45 +0000

It might sound a little out of place - talking about planting techniques for sunflowers when harvest is just around the corner - but Syngenta agronomists want to remind growers that planting is the time to cut down on harvest problems. Many harvest problems are a direct result of planting mistakes. When prepping for harvest this season, observe any areas that may have uneven stand, and make adjustments for next planting season. An uneven stand with different sized heads can cause a lot of problems when it comes to harvest time, including stalk lodging. Some sunflower heads get very large where there is wide seed spacing. Those large heads weigh more than what the stalk is designed to hold and, during days of high winds, the force of the head swaying back and forth can break the stalk off, which creates a tougher harvest. The photo above is an example of a field that could have harvest problems due to unprecise planting. Keep these three things in mind when planting sunflowers to ensure a healthy stand:

Select the correct plates. Use plates designed for sunflower fields and more precise planting.
Slow down. Keep planting speeds at around 4 mph.
Make sure planting depth is set correctly. Try to plant sunflowers between 1 and 2 inches deep.

How to Manage Soybean Sudden Death Syndrome

SyngentaAgronomy — Tue, 02 Aug 2016 18:20:48 +0000

Among the most destructive soybean diseases, sudden death syndrome (SDS) has the potential to significantly reduce soybean yields. The majority of U.S. soybean growers are affected by SDS once in every four years. The environment plays a strong role in whether SDS appears in any given year or area. The risk of SDS infection is greatest when significant moisture occurs early in the growing season followed by heavy mid-summer rains saturating the soil. While management options are limited, there are measures growers can take to proactively reduce the risk of SDS outbreaks. Preventive actions are essential because once the disease becomes apparent, control options are ineffective. Experts recommend:

Planting fields without a history of SDS first
Plant fields with a history of SDS later because young, slower growing plants are more susceptible to infection
Taking measures to avoid or reduce soil compaction

The occurrence and severity of SDS is also in part dependent upon soybean cyst nematode (SCN) presence. SCN influences SDS both directly and indirectly. SCN feeding within the root opens it for infection, while stress caused by SCN feeding weakens the plants’ defenses to disease. These two SCN influences are important factors related to root-affecting diseases. As a result, managing SCN populations has the potential to limit SDS severity. Beyond these agronomic recommendations, Syngenta has varieties and seed treatment options to improve disease management:

NK® Soybeans have proven tolerance to SCN, SDS and other pests and diseases.
Clariva® Complete Beans seed treatment, a combination of separately registered products, provides effective, season-long protection against SCN. Clariva Complete Beans also reduces the damage from SCN-related diseases, such as SDS.
Mertect® 340-F fungicide seed treatment has shown consistent performance and yield protection under SDS pressure in four consecutive years of testing. Mertect 340-F also offers additional activity on seedborne diseases, such as Phomopsis. Mertect 340-F can be added to Clariva Complete Beans to expand the pest protection to SDS.

Planting SCN-tolerant and SDS-resistant NK Soybeans treated with these seed treatments can help grow more soybeans achieve higher yields.

Fight Botrytis In-Season to Protect Grape Harvest

SyngentaAgronomy — Thu, 04 Aug 2016 14:04:06 +0000

CALIFORNIA: With higher than average rain falls this year during the maturation of grape crops, the risk for Botrytis pressure is escalated as well. Botrytis, also known as gray mold and bunch rot, can result in major yield loss for the vines infected. According to the University of California Integrated Pest Management Program, successful management of Botrytis can be achieved through the use of several strategies:

Cultural control methods: Manage canopies, avoid unnecessary irrigation or nitrogen fertilization, and manage insect populations.
Fungicides. Utilize fungicides with different modes of action, especially if major rain is expected.
Resistant cultivars. Use varieties that are resistant to diseases.

Syngenta offers Switch® fungicide to protect grapes from devastating diseases such as Botrytis. Applied as a preharvest treatment, Switch provides up to six weeks of postharvest protection from profit-robbing diseases like sour rot and Botrytis. Combining two modes of action to provide multi-stage and long-lasting protection from infection on both leaves and fruit, Switch helps growers maximize return on investment.

New Wheat Varieties for the Plains

SyngentaAgronomy — Tue, 09 Aug 2016 16:13:50 +0000

Every season, Mother Nature provides new curveballs that growers can’t control. Factors such as temperature, wind, disease pressure, rain/snow and frost can be detrimental to yields. Because of this, experts recommend implementing an integrated approach to crop management this upcoming winter wheat planting season. A robust plan and smart seed purchases can help start the season strong. Planting quality certified seed varieties and incorporating good planting practices, such as residue management, following proper seeding rates and applying seed treatments, are critical to helping wheat start strong. The AgriPro^® brand wheat portfolio provides locally bred varieties that offer consistent performance and quality under varying conditions. For the Plains region, AgriPro is adding two new winter wheat varieties 2016 planting:

SY Flint: With a strong pedigree that includes Jagalene and Oklahoma State University wheat variety Duster, SY Flint has high-end yield potential and a medium early maturity. This variety has outstanding agronomic traits, including low pH tolerance, Hessian fly resistance and excellent test weight and straw strength. SY Flint has good disease tolerance traits, including tolerance to stripe rust, and barley yellow dwarf virus (BYDV). This variety is well suited for both dryland and irrigated acres in Kansas, Oklahoma and northern Texas.

SY Sunrise: SY Sunrise is the highest yielding irrigated wheat variety from AgriPro. This variety offers good straw strength and is short in height. It’s a very high tillering variety, with large seeds, excellent test weight and good winter hardiness. This variety has good disease tolerance to stripe, leaf and stem rust. SY Sunrise is best suited for high yielding environments like irrigated acres in the Western High Plains. SY Sunrise also requires a Seed Stewardship Agreement specifying No Saved Seed, in order for farmers to maximize their yield by using quality certified seed each growing season.

Bollworms Invade South Carolina Cotton Fields

SyngentaAgronomy — Wed, 10 Aug 2016 12:58:48 +0000

According to Dr. Jeremy Greene, entomologist with Clemson University, there have been reports of cotton bollworms in the Pee Dee region of northeastern South Carolina escaping Bt cotton technology. Bollworms damage cotton blooms and bolls and can result in severe yield loss. To check for bollworms escaping Bt technology, Dr. Greene suggests careful scouting, including the removal of bloom tags from the top of bolls to inspect for damage. An additional option for managing bollworm populations is Besiege® insecticide, which provides excellent knockdown and long-lasting residual of the most difficult-to-control lepidopteran pests and other economically important pests.

Worm Pressures Call for Diligent Soybean Scouting

SyngentaAgronomy — Thu, 11 Aug 2016 15:57:14 +0000

SOUTHERN STATES: Entomologists recently reported sightings of corn earworm and armyworm. Because of this, experts encourage growers to scout often, and thoroughly. Gus Lorenz, extension entomologist at the University of Arkansas Extension, warns growers to be on the lookout for corn earworm and other defoliating pests, such as fall armyworm and yellowstripes. Currently, Lorenz is seeing them in soybeans that are starting to bloom and set pods, and a lot in fields that are in the R1 to R2 stage. Small, late-planted beans are particularly vulnerable to foliar damage. Clemson University Extension advises growers to scout weekly for corn earworm from the last week of July through August. Defoliation should not exceed 15 percent after mid-bloom or 30 percent before mid-bloom. With soybean commodity prices constantly fluctuating, it is important to be conservative with scouting efforts. Lorenz recommends dropping the scouting threshold for worms to somewhere between seven and nine worms. In July, growers in many fields were already finding as many as 12 worms per 25 sweeps. To combat these pests, it’s also crucial that growers choose the right insecticide for the job. For protection against corn earworm, armyworm and other foliar-feeding pests, Syngenta offers Besiege^® insecticide. Besiege provides excellent knockdown and long-lasting residual of the most difficult-to-control lepidopteran pests.

Early Soybean Management Choices Affect the Entire Season

SyngentaAgronomy — Fri, 12 Aug 2016 15:34:49 +0000

Poorly drained or flooded fields. Many soilborne pathogens require moisture, this provides an environment conducive to disease.
Low seeding rates. With less seed planted, each and every seed becomes more important.
Cool spring or planting early. Under these conditions, seedlings take longer to emerge, giving the soilborne pathogens more time to feed.
Fields with a history of pests. It’s important to look back at the history of the field to prepare for the next season.

Syngenta offers CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products, to help growers enhance RootingPower and protect soybeans from early-season pests. CruiserMaxx Vibrance:

Warm Weather Brings Unwelcome Illinois Pests

SyngentaAgronomy — Mon, 15 Aug 2016 13:04:57 +0000

Illinois growers have experienced some fluctuating weather patterns this growing season. Starting with a hot and humid early summer and switching to a wet mid-summer, growers are continuously discovering different issues popping up in their fields. At the Pana, Illinois, Grow More^TM Experience site, we, too, are tackling tough pests that come with changing weather patterns. Disease Updates from the Pana Site Some of the common corn and soybean diseases we are observing this summer include:

Northern corn leaf blight
Gray leaf spot
Common rust
Septoria leaf spot
Frogeye leaf spot
Sudden death syndrome (SDS)

We are testing a number of fungicides at our site, and Trivapro ® fungicide continues to stand out. Trivapro fungicide provides preventive and curative activity on several key diseases, including gray leaf spot, northern corn leaf blight, rusts, frogeye leaf spot and Septoria leaf spot. With three active ingredients, including Solatenol® fungicide, Trivapro delivers long-lasting disease control and crop enhancement benefits for maximized yield potential across corn and soybean crops. SDS is one of the most devastating soybean pathogens. According to the Iowa Soybean Association, SDS has resulted in nationwide yield losses of 20-30 million bushels over the last 10 years. The battle against SDS in soybeans is being won in Pana where seeds were treated with Clariva® Complete Beans seed treatment, a combination of separately registered products. Clariva Complete Beans offers season-long soybean cyst nematode (SCN) protection, as well as reduced damage from SCN-related diseases, such as SDS. Adding Mertect® 340-F seed treatment fungicide with direct activity on SDS provides a double mode of action to help manage the disease.

Beware of Corn Ear Rot Pressure in Indiana, Illinois

SyngentaAgronomy — Wed, 17 Aug 2016 13:41:42 +0000

Regions throughout Illinois and Indiana have been experiencing increased rainfall during and after pollination, which can cause favorable conditions for corn ear rot development. For growers experiencing ear rot pressure, it’s best to harvest as soon as the grain reaches 25 percent, and then dry the grain quickly to below 15 percent moisture (preferably to 13 percent moisture). This will help to minimize spreading within the stored grain. Affected growers can also consider adjusting the fan speed of their combine. If they have a rotary grain cleaner, growers are advised to lower their fan speed when unloading grain before storage to help remove lighter kernels and fines. Growers who don’t have a rotary grain cleaner can turn up their fan speed to help blow out light and damaged kernels, although they should be mindful that the increased speed can inoculate the field for future crops. Below is an overview of the major types of corn ear rots below to aid in scouting and identification efforts. Major types of corn ear rots: Diplodia ear rot starts at the base of the ear and works its way up, often infecting the whole ear. It is a dense, white mold that becomes grayish-brown and has raised black fruiting bodies that can be seen later in the season. This disease is often favored by wet weather just after silking and is more severe in corn-on-corn fields. While Diplodia ear rot does not produce a toxin, it produces a lighter test weight (TW) kernel and discoloration, which may cause dockage when delivering the grain. Residue on the soil surface can be a prime inoculate environment. Even residue from two years ago in no-till or reduced tillage situations can be a factor as corn is the only known host crop. Diplodia ear rot can spread by wind or rain. The level of this disease within a field is highly proportional to the amount of infected corn residue on the soil surface.

Diplodia ear rot

Gibberella ear rot almost always starts at the tip of the ear and works its way down the ear. The initial mold infection may be very pale and white, but as the mold progresses, growers may see the mold develop to a red or pink color. Growers should keep in mind that this is the same fungus that causes head scab in wheat, so there is another host crop to be aware of for management and potential inoculate issues. Infection is caused by cooler, wetter weather during and after pollination, and occurs through the young silk stage. This can, again, reduce TW and impact grain quality with discolored kernels and kernel damage. Gibberella ear rot also develops vomitoxin, a toxin that may cause elevators to reject loads if the level is too high. Vomitoxin can cause feed refusal and poor weight gain especially in swine.

Gibberella ear rot

Fusarium ear rot is identified by scattered or random grouping of affected kernels. Early infection typically shows “starburst” white streaking in the affected kernels, which starts at the top of the kernel and streaks down the sides. This can happen because the point of infection is where the silk attached to the kernel ovule. Streaked mold often starts out white and may later turn pink or salmon-colored. Fusarium ear rot produces fumonisins, which are highly toxic to some species, especially horses, dogs, and rabbits. Fungi of this disease survive on corn and many other grass species, so there are many host plants that can contribute to the level of this disease. Unlike the other common ear rot diseases, however, Fusarium ear rot favors warm and dry conditions. Because of this tendency to favor warmer temperatures, an additional harvest management recommendation is to cool stored grain to below 50 degrees as soon as possible to slow the spread within the bin. Cladosporium ear rot is identified by scattered kernels that have dark brown to green fuzzy mold which can cause random dark kernels to appear rotted with ruptured kernel caps. This ear rot is not associated with mycotoxins, so it only impacts grain quality and potential harvest dock due to lighter TW and kernel discoloration. Cladosporium ear rot is fairly common, but its true yield impact is limited. Penicillium ear rot is identified by blue-green fungal growth usually found at the tip of the ear. This disease can also be associated with physical damage from birds and/or insects, which may occur to the tip of the ear. Mycotoxins and ochratoxins may occur with this disease and, at certain levels, can be toxic to mammals. High humidity is the biggest factor in disease development and spread of the rot.

Illinois Agronomists Educate Local Growers, Resellers

SyngentaAgronomy — Tue, 16 Aug 2016 13:33:09 +0000

Ongoing education is an important pillar at the Syngenta Grow More^TM Experience sites. Recent topics of interest at the Pana site included: the difference between waterhemp and Palmer amaranth, the three most common soil types, and the importance of applying nitrogen. These are all trials we address in our Pana trials. Waterhemp vs. Palmer Amaranth Growers often ask how to tell whether waterhemp or Palmer amaranth has invaded their fields. The test is simple. Fold the leaf over its stem. If the stem is shorter than the leaf, it’s waterhemp; if the stem is longer than the leaf, it’s Palmer amaranth. Knowing Which Soil Types Help Maximize Yield Illinois growers will encounter three main soil types: coarse, finely, and moderate-textured.

Coarse soil drains water well but does not have a very high water-holding capacity.
Finely-textured soil holds water and nutrients well but does not drain at a desirable rate.
Moderate-textured soil, however, is the best of both extremes, with qualities like adequate drainage and strong nutrient and moisture-holding capacities.

Syngenta believes it is important to study these characteristics at the Pana Grow More Experience site. When growers understand each field’s soil type, they can better evaluate which hybrids and varieties are best suited for maximum yield potential on that particular field. Syngenta agronomists are trained to help growers match soils to the most appropriate hybrid and variety. The Importance of Nitrogen to Combat Disease Syngenta also has trials to help demonstrate how nitrogen plays an important part of healthy plant growth. Too much or too little of the element can make crops more prone to disease. Balanced nitrogen levels can help protect crops from common diseases and the impacts of unpredictable Illinois weather. To learn more about these topics and receive additional agronomic training at the Pana Grow More Experience site, contact your Syngenta representative.

Bouncing Back from Weather Woes in Ohio

SyngentaAgronomy — Thu, 18 Aug 2016 15:46:18 +0000

Mother Nature hasn’t been kind to Ohio growers this season, as farmers across the state are dealing with low amounts of rainfall in their fields. At the Marysville Grow More^TM Experience site, we are facing the same challenges. In fact, since we planted on April 19, the site has received less than six inches of rain in total. This hot and dry growing season is taking its toll on the plots, but some interesting results are still emerging in our trials. Herbicide and Fungicide Trials The Syngenta herbicide portfolio, despite the little moisture present to activate herbicides, has been resilient. Weed pressure continues to be held off remarkably well, allowing crops the chance to survive despite poor weather conditions. In addition, many growers believe that with such a low moisture level, disease pressure is also lower. As visitors to the site can see, the Trivapro® fungicide corn trials are far outperforming competition and untreated plots, producing noticeably healthier leaves and fuller canopies. Pest Updates in Ohio Due to the weather patterns in Ohio, growers should keep an eye out for Japanese beetles, grasshoppers and spider mites, which are already being spotted in parts of the state. Continue to scout your fields for insect pressure, and protect your corn and soybean yields from these pests. To schedule a visit to the Marysville site, contact your Syngenta representative.

Knocking Back Kudzu Bugs in Soybeans

SyngentaAgronomy — Mon, 22 Aug 2016 22:09:41 +0000

According to Clemson University Extension, average yield loss for untreated soybeans due to kudzu bugs has been observed at 20 percent in South Carolina and Georgia, but could be as high as 50 percent. As kudzu bugs continue to spread, the threat they pose to soybean yields is becoming apparent to growers. Although these pests feed on the pesky vine for which they are named, their diet also includes legumes, especially soybeans. They feed on soybean stems and petioles by sucking nutrients with their piercing-sucking mouthparts, putting stress on the plant. Large, uncontrolled populations of these nutrient-robbing pests have definite potential to cut yield. The first generation of kudzu bugs moves from kudzu to soybeans in early summer while the second generation migrates in late-July or early-August, making soybean crops susceptible to damage throughout the season. Because of this, it’s important that growers continually scout throughout the season. Researchers throughout the Southeast are working to determine uniform threshold and control measures for the kudzu bug, while continuing to caution soybean growers of their yield-robbing potential. By combining three industry-leading technologies of lambda-cyhalothrin, thiamethoxam and the microencapsulation process of Zeon® Technology, Endigo® ZC insecticide can provide fast knockdown and long-lasting residual control, helping soybeans yield strong despite pest pressures.

New Interactive Tools to Educate About Soilborne Pathogens

SyngentaAgronomy — Mon, 22 Aug 2016 15:51:34 +0000

School is back in session for growers and retailers interested in learning about the impact of soilborne pathogens on their corn, soybean and wheat fields. Syngenta Seedcare recently launched two new online tools, the Vibrance® seed treatment fungicide Learning Module and the Vibrance Interactive Infographic, to educate and build awareness about the impact of soilborne pathogens on root health and crop productivity in corn, soybeans and wheat. The learning module walks participants through a series of sections, including an in-depth look at the importance of root health, disease protection and the benefits of Vibrance. Participants are eligible to receive one Integrated Pest Management CEU credit for completion. The interactive infographic visually leads users through young corn, soybean and wheat crops to demonstrate the impact of Rhizoctonia, as well as the RootingPower benefits of Vibrance. Syngenta believes it is important to provide growers and retailers with visually stimulating educational tools that explain the concept of root health and the products Syngenta offers to help maximize RootingPower from the very beginning of the season. For more information about Vibrance or to check local availability, growers can contact their Syngenta representative or co-op agronomist.

Prevent Yield Loss in Sugarbeet Piles While in Storage

SyngentaAgronomy — Tue, 23 Aug 2016 21:06:54 +0000

According to the Sugarbeet Research & Education Board of Minnesota and North Dakota, it’s estimated that respiration causes about 70 percent of sugar loss during storage, and decay accounts for 10 percent. The remaining 20 percent of sucrose losses are the result of fermentation when oxygen content is low because of poor ventilation, freezing and thawing cycles and root desiccation. How can growers maintain sugarbeet health, tonnage and sugar quality when sugarbeets are in piles after harvest? Syngenta recommends the following to help prevent post-harvest yield loss in the pile:

Utilize proper defoliation. Avoid overly aggressive crown removal. This results in up to three times more decay and increases respiration loss.
Improve ventilation by keeping piles as free as possible of dirt, weeds, rocks, leaves and other debris.
Keep piles at a cool temperature (below 50° F) to avoid decay and sugar degradation.
Use forced-air ventilation and freeze piles over the winter to help control storage losses due to respiration.
Use clean equipment. Maintain harvest equipment – from defoliators and lifters to trucks and conveyors.
Prepare slabs properly.

Sudden Death Syndrome Hits Soybean Fields

SyngentaAgronomy — Wed, 24 Aug 2016 22:11:49 +0000

Sudden death syndrome (SDS) is back again – unfortunately not surprising, given that this year’s early planting and wet, cool spring conditions in many parts of the Midwest were ideal for SDS to infect soybean roots. The environment plays a strong role in whether SDS appears in any given year or area. The risk of SDS infection is greatest when significant moisture occurs early in the growing season followed by heavy mid-summer rains saturating the soil. We’ve mentioned before that it’s important to proactively reduce the risk of SDS outbreaks. Additionally, utilizing SDS tolerant varieties and seed treatments with protection against SDS can help protect soybean yields.

NK® Soybeans have proven tolerance to soybean cyst nematode (SCN), SDS and other pests and diseases.
Clariva® Complete Beans seed treatment, a combination of separately registered products, provides effective, season-long protection against SCN. Clariva Complete Beans also reduces the damage from SCN-related diseases, such as SDS.
Mertect® 340-F fungicide seed treatment has shown consistent performance and yield protection under SDS pressure in four consecutive years of testing. Mertect 340-F also offers additional activity on seedborne diseases, such as Phomopsis. Mertect 340-F can be added to Clariva Complete Beans to expand the pest protection to SDS.

Planting SDS-resistant NK Soybeans treated with these seed treatments can help mitigate the risk of SDS and, ultimately, help farmers grow more soybeans.

Arkansas Site Highlights Weed Control and Root Health

SyngentaAgronomy — Thu, 25 Aug 2016 22:12:21 +0000

This July, Syngenta hosted a Grow More™ Experience event in Bay, Arkansas to showcase some of their premier products for use on corn, soybeans and cotton. During the event that took place over three days, customers, growers, retail partners and media outlets, got the chance to walk in the fields to see and touch the trials. While Bay hasn’t faced much disease pressure throughout the season, diseases were just starting to creep into the fields during the event, so customers got a first-hand look at the kind of power Syngenta products have against insects, weeds and diseases. Syngenta can customize the treatments and have them interact directly with diseases to demonstrate how the products really work. Some of the products highlighted during the tour were:

NK® Corn hybrids and NK Soybean varieties
Corn herbicide and fungicide trials showing control against southern rust
Soybean fungicide trials combating frogeye leaf spot
Soybean and cotton seed treatment test plots

The two most notable demonstrations at the event showcased the power of Acuron® herbicide. In a comparison of treated rows with those that were untreated, customers left saying that they were impressed with how clean corn rows were after being treated with Acuron. During the Syngenta Seedcare portfolio demonstration, products like Vibrance® seed treatment fungicide showed just how powerful it can be underground. In a comparison trial, agronomists showed growers how seeds treated with Vibrance promoted a more robust and fuller root system compared to untreated seeds.

Michigan: Be on the Lookout for Fall Armyworm

SyngentaAgronomy — Fri, 26 Aug 2016 14:36:20 +0000

Migrating from Southern states, fall armyworm has been found in Michigan sweet corn. Often sneaking by as growers focus on corn earworm, fall armyworm can be devastating to sweet corn fields. Michigan State University Extension outlines tips to manage fall armyworm:

Scout for fall armyworm on the leaf whorl and developing tassel
Use pheromone lures and green bucket traps to monitor moth populations, if fields have a history of this pest
Utilize treatments if moths are being caught in traps or larval damage is present

For fall armyworm control, Syngenta recommends an insecticide such as Besiege®. Besiege provides excellent knockdown and long-lasting residual of the most difficult-to-control lepidopteran pests and other economically important pests. Its convenient premix formula contains two active ingredients with complementary modes of action for dual protection against key insect pests.

Beet Armyworm Infestations Return to Tennessee Fields

SyngentaAgronomy — Mon, 29 Aug 2016 13:40:41 +0000

According to Dr. Scott Stewart, entomologist with University of Tennessee, beet armyworms are showing up in cotton and soybeans across the state. If not managed early, this pest can be devastating to yields. Since there have not been infestations of beet armyworm in the area for a few years, growers may confuse this insect with fall armyworm. For best control, it is important to differentiate the two pests. To protect Tennessee cotton and soybean yields, Besiege® insecticide can help control beet armyworm outbreaks. Its convenient premix formula contains two active ingredients with complementary modes of action for dual protection against key insects. Other highlights include:

Contact, ingestion and ovicidal activity
Controls lepidopteran pests, including soybean looper, armyworms and corn earworm
Delivers longer-lasting residual than other lepidopteran materials
Protects against stinkbugs, grasshoppers, adult moths and beetle species

Importance of Multiple Modes of Action

SyngentaAgronomy — Wed, 31 Aug 2016 18:00:50 +0000

Weed resistance is expanding and growers are looking for new tools to control the toughest weeds in corn. Multiple modes of action are critical for effective management against tough weeds. Syngenta recently conducted a trial to highlight the importance of using multiple effective modes of action, and is featuring the results at Farm Progress Show. This trial explains why Syngenta herbicides Acuron®, Acuron Flexi and Halex® GT outperform other herbicide products. In a greenhouse trial* located in Slater, IA, 4-inch pots were filled with soil, seeded with Palmer amaranth and then each pot was sprayed with either:

Acuron, Corvus®, or SureStart® herbicide or one of their individual active ingredient components pre-emergence
Halex GT or Armezon® PRO herbicide or one of their individual active ingredient components post-emergence

The results of this trial show that Syngenta herbicides have more effective modes of action for residual control compared to Corvus, SureStart and Armezon PRO. With Acuron, growers get burndown plus residual through a combination of bicyclopyrone, mesotrione, S-metolachlor and atrazine. Acuron Flexi also provides improved and more consistent control with added flexibility, through a combination of bicyclopyrone, mesotrione and S-metolachlor. Halex GT is Glyphosate with Residual™ and provides a more convenient alternative to any other post-emergence, straight glyphosate corn herbicide program. Containing mesotrione, S-metolachlor and glyphosate, Halex GT delivered more effective residual control of Palmer amaranth compared to the components in Armezon PRO. Multiple effective modes of action are needed to control the toughest weeds in corn.

Arkansas Sees Highest Fall Armyworm Levels in Years

SyngentaAgronomy — Thu, 01 Sep 2016 21:29:42 +0000

Too much rain may be the main headache for growers in the mid-south, but there are a few pests that growers should keep an eye on too. According to Dr. Gus Lorenz, extension entomologist with the University of Arkansas, stinkbugs, including red-bandeds, and loopers are present in fields. However, the most impressive pest threat Arkansas growers are currently facing is the fall armyworm. While fall armyworms in Arkansas may not be unusual, these extremely high levels are. The numbers Lorenz is seeing across the state are incredible—the highest he has seen in his career—and could be even worse in September. To battle these armyworm invasions, Lorenz recommends an insecticide with residual control like Besiege®. Besiege provides excellent knockdown and long-lasting residual of the most difficult-to-control lepidopteran pests and other economically important pests.

Last Call Before Harvest: Buckeye State Agronomic Update

SyngentaAgronomy — Fri, 02 Sep 2016 13:36:47 +0000

Corn growers: If you haven’t already done field yield estimates for your corn crop, you should. That way, you’ll have a better idea of your yield guestimates when you fire up the combine and head out to your fields in a few weeks. As a reminder on how to calculate your corn yield estimate, use the following formula:

Take 1/1000 of an acre, or 17 feet, 5 inches in typical 30”rows. Count the number of harvestable ears. You generally have fewer plants than your initial seeding rate and not every plant may have a harvestable ear. Example: Planted 34,000 seeds /acre, 29 harvestable ears.
Take 3 ears from the beginning, middle and end of your 1/1000 of an acre and average the numbers of kernel rows around the ear. Kernels around should always be an equal number. Example: 16 +16+14 = 46. Divide by 3 = 15.33 rows around
Then count the length of your kernel rows. But don’t count the tiny kernels on the end, or the irregular kernels on the butt of the ear. Example: 40 + 33+ 35 = 108. Divide by 3 = 36 kernels long
Now that you have kernels around by kernels long, you can find your estimated yield, or bushels per acre, by multiplying the ear count by kernels around by the kernels long divided by 90. The reason you divide by 90 is because there are roughly 90,000 kernels per bushel. Example (29 x 15.33 x 36)/90 = 178 bu/A.
It’s always a good idea to repeat this estimate several times to get a more accurate result.

Heat Can Reduce Grain Fill While the USDA World Agricultural Supply and Demand Estimates report has projected an oversupply of corn in the U.S., keep in mind that while the national level is important, the individual field level is most important to a farmer. An often overlooked factor that will affect yields this year are the hot nights in addition to hot days. Many Ohio growers experienced summer days with temperatures in the 90s, and also summer nights in the 80s. This makes a big difference in yields because corn plants make sugar during the day, but if it’s hot at night, they burn most of the recently built sugars in respiration. With energy burned comes a loss of grain fill. To protect corn crops from being hit by a double heat wave in 2017, take a look at hybrid temperature tolerances as you evaluate Golden Harvest® Corn and NK® Corn seed selections. It also doesn’t hurt to look at how estimated hybrid heat tolerance ratings stack up to actual yield numbers once harvest is kicked off this year. Spreading risk through genetic variety means that some hybrids will perform better in a hot year and some will perform better in a cool year. Don’t forget there are many other factors that go into final hybrid performance – everything from planting depth to weeds, disease, insects, rainfall, nitrogen levels and more.

Why Some Corn Ears Tip

SyngentaAgronomy — Tue, 06 Sep 2016 21:56:59 +0000

Syngenta agronomists at the 2016 Farm Progress Show in Boone, IA, said they are seeing corn ears tip back about one inch this year. A tipped ear is where the cob head bends back slightly and results in a loss of several end kernels, just as the first corn ear pictured to the far left above does. Though many growers are still counting a good number of ears that are 32-34 kernels long, some kernels have still been lost due to the high temperatures in Iowa this season. While corn can often handle temperatures up to 93 degrees, Iowa growers saw several days in the mid-nineties this summer. In addition, the unusually high number of warm nights and early mornings had an impact on kernel loss. Right at and after pollination is an especially critical temperature window for ear tips because these stages are a prime time for kernel growth.

Four Essential Components of Effective SCN Management

SyngentaAgronomy — Wed, 07 Sep 2016 17:04:57 +0000

Soybean cyst nematode (SCN) has been around since 1954, yet it still claims the spot as the No.1 soybean pest in the U.S. Why? SCN-resistant varieties are no longer as effective as they used to be due to overreliance on a single source of genetic resistance, PI88788. In addition, one nematode can result in 1.6 billion eggs in a season and up to 40 percent in yield loss with no above-ground symptoms. Bruce Battles, Seedcare technology manager at Syngenta, took the stage at Farm Progress Show to advise growers on what they can do to take control of SCN. Four essential SCN management practices:

Rotate soybeans with non-host crops.
Plant SCN-resistant varieties.
Try to plant varieties with different sources of genetic resistance.
Apply a seed treatment with a nematicide.

Growers can enhance their SCN-resistant varieties with a seed treatment, like Clariva^® Complete Beans seed treatment, a combination of separately registered products. Clariva Complete Beans provides season-long direct, lethal activity against SCN, reducing SCN feeding and reproduction. Effective in all environmental conditions, it offers an attractive return on investment through four main benefits:

Yield increase from season-long protection against SCN
Enhancement of SCN-resistant varieties
Reduced SDS damage
Better long-term SCN management

Clariva Complete Beans includes the active ingredient, Pasteuria nishizawae, which releases spores that attach to the nematode (shown above), ultimately killing it. Until new sources of genetic resistance come to market, growers must diversify their management programs with revolutionary modes of action like that of Clariva Complete Beans.

Manage Corn Rootworm from the Start

SyngentaAgronomy — Fri, 09 Sep 2016 15:40:45 +0000

Heavy rains thwarted the threat of high corn rootworm (CRW) pressure for the past two seasons in the Midwest. This season, however, is turning out to be a different story with many areas experiencing the damaging effects of CRW pressure. When making a seed purchase, it can be tempting to reduce costs by purchasing hybrids without CRW control technologies, but that leaves seed investments vulnerable to these damaging pests. If CRW attack hybrids without proper control traits, it can result in more money spent on in-season insecticide applications and lost yield. Post-applied insecticide treatments are not effective in controlling CRW larvae - protection from larvae comes from in-seed trait technology. Because of this, a CRW management program must begin with proper hybrid selection. To ensure that corn plants are able to establish strong roots, achieve their full genetic potential and maximize yield potential, agronomists warn against skipping proper CRW control in geographies that have a history of CRW infestation, especially when planting a corn-on-corn operation. Planting hybrids without dual modes of CRW control in corn-on-corn fields can result in severe damage and yield loss. Effective CRW management requires the integration of multiple control measures, not a singular technology. Long term CRW management requires a multi-year, whole farm approach. To get ahead of corn rootworm, Syngenta agronomists recommend the following management options:

Rotate fields with a non-host crop. In fields that have experienced high CRW pressure, or in corn-on-corn fields, growers may want to rotate to a non-host crop, which provides the best opportunity to break the reproductive cycle of CRW.
In operations where crop rotation is not an option, plant a multi-stacked trait product. Syngenta recommends that growers use trait stacks containing multiple CRW traits such as Agrisure Duracade® trait stacks, which combine the Agrisure® RW trait with the Agrisure Duracade trait.
If no CRW trait was planted, use a soil-applied insecticide. Growers should consider an insecticide application such as Force® 3G insecticide which provides control of corn rootworms, wireworms, cutworms, white grubs and other troublesome soil pests.

Identifying Lodging May Save Corn Yields

SyngentaAgronomy — Mon, 12 Sep 2016 15:56:00 +0000

According to Dr. Scott Stewart, integrated pest management extension specialist at the University of Tennessee, growers who planted non-Bt corn, particularly ones observing some lodging take place, might want to consider harvesting those fields first. Annual yield loss due to corn stalk lodging in the U.S. can range between 5 and 25%, according to the Purdue University extension. Some lodging may be due to southwestern or European corn borer feeding. By harvesting those fields as soon as possible, growers may be able to prevent some harvest losses related to lodging or eardrop.

Tobacco Black Shank is a Challenge in 2016

SyngentaAgronomy — Tue, 13 Sep 2016 20:42:37 +0000

KENTUCKY: Tobacco black shank, caused by the Oomycete pathogen Phytophthora nicotianae, is giving growers a run for their money this year. One of the most yield-robbing diseases in tobacco, black shank overwinters and survives in soil for at least four to six years, making prevention key to combating this pathogen. Spread It’s important to understand how this pathogen spreads in order to prevent it. The University of Kentucky explains that black shank can be spread through water or soil movement, via tractor tires, cultivators, fertilizer spreaders, contaminated tools and even workers’ boots. Symptoms Symptoms of black shank start as wilting during the heat of the day, though early on plants may appear to recover overnight. Later, plant leaves become yellow (chlorotic), as seen in the photo above, and don’t recover from wilt even under conditions of adequate moisture. These plants are often stunted and have blackened tissue within the stem at the root-stem interface. In late stages of the disease, plants die back completely and in severely affected fields, yields are significantly reduced, according to the University of Kentucky. Management Experts recommend that growers should begin implementing tactics now to manage black shank. The University of Kentucky recommends that growers be proactive, using the following three-pronged approach:

Crop rotation. Rotate fields away from tobacco for three to five seasons to reduce levels of the black shank pathogen. While it can never be truly eradicated from fields, black shank can be significantly reduced by growing non-host crops over several seasons.
Resistant varieties. For fields with any history of black shank, choosing a resistant variety is key. In Kentucky, two different races of the black shank pathogen are common and unless specific farm populations have been tested, the most conservative approach is to choose a variety that’s resistance to both races.
Fungicides. Apply fungicides in transplant water as well as soil-directed sprays. Fungicides available for application in transplant water include Ridomil Gold® SL and Orondis® Gold 200 (combine to form Orondis Ridomil Gold SL). At first cultivation and layby, Ridomil Gold SL and Orondis Gold 200 may be used. Post-transplant applications are most effective when directed at soils using drop nozzles followed by cultivation to move the fungicide into the root zone.

Combining the active ingredient oxathiapiprolin with the proven, trusted performance of mefenoxam, Orondis Ridomil Gold SL offers control that growers can rely on. As the only active ingredient in FRAC Group U15, oxathiapiprolin is not cross-resistant to any other fungicide and offers built-in resistance management when included in a season-long Oomycete disease control program. Growers can speak with their Syngenta representative to learn more about Orondis Ridomil Gold SL in tobacco. A well-executed fungicide program and good management practices can help Kentucky tobacco growers reduce the spread of black shank, setting themselves up for a more profitable season.

Grow More Experience Site Prevails Over Pests

SyngentaAgronomy — Wed, 14 Sep 2016 16:18:16 +0000

This season, growers in the Red River Valley have been battling Rhizoctonia in sugarbeets and soybean cyst nematode (SCN) in soybeans. Fortunately, crop management solutions are being showcased at the Glyndon Grow More™ Experience site in western Minnesota. Sugarbeets Sugarbeet trials tested the performance of seed varieties and seed treatments against devastating diseases like Rhizoctonia and Aphanomyces, which often go hand-in-hand. Hilleshog® brand sugarbeet seeds demonstrated the strength of their genetic tolerance to both diseases. To enhance and expand disease and insect protection, all varieties were treated with CruiserMaxx® Sugarbeets seed treatment insecticide/fungicide, a combination of separately registered products, and Vibrance® seed treatment fungicide. As the photos below show, CruiserMaxx Sugarbeets and Vibrance helped produce greener leaves with invaluable chlorophyll that helps accumulate every point of sugar. From the photos above, you can see how well CruiserMaxx Sugarbeets and Vibrance seed treatments with Inspire ^® XT fungicide (right) controls Cercospora leaf spot (left) compared to untreated sugarbeets (left). Soybeans Five years ago, Red River Valley growers typically didn’t view SCN as a threat because soybean seed genetic tolerance was sufficient. However, this pest has become increasingly challenging. Many growers now use Clariva® Complete Beans seed treatment nematicide/insecticide/fungicide, a combination of separately registered products, as a solution. As demonstrated at the Glyndon Grow More Experience site, Clariva Complete Beans also helps promote early plant growth, therefore enabling soybeans to have a better chance of outgrowing weeds in the race to canopy. With lethal, season-long protection against SCN, Clariva Complete Beans has also shown an average national yield increase of 2.6 bushels per acre (bu/A) compared to an insecticide/fungicide seed treatment alone.

More Control of More Pests for More Corn

SyngentaAgronomy — Thu, 15 Sep 2016 18:17:03 +0000

It’s one thing to hear about the yield difference a hybrid makes. It’s another to see the difference yourself. That’s exactly what one of the Columbia, MO, Grow More™ Experience site trials is showcasing this summer. All comparison plots at Grow More Experience sites are planted at the same time, using the same agronomic protocols and crop inputs. Not just that, but they also weather the same conditions Mother Nature brings – whether it’s heavy insect or disease pressure, a great rain, drought or hail. In 2016, 1 of the trials at the Columbia, MO, Grow More Experience site tested the Agrisure Viptera® 3111 trait stack against two industry competitors. All 3 trait stacks control above-ground insects, and from the pictures above, it is clear which one outshines the competition thanks to the Agrisure Viptera trait. With control of up to 16 above- and below-ground insects, Agrisure Viptera trait stacks deliver more high-quality grain through the most comprehensive corn insect control.

Cercospora Leaf Spot & Black Bean Aphids in Idaho Sugarbeet Fields

SyngentaAgronomy — Fri, 26 Aug 2016 13:10:28 +0000

IDAHO: The Pacific Northwest Pest Alert Network has confirmed that Cercospora leaf spot and black bean aphids have been spotted in sugarbeet fields in the Wendell and Rupert areas of Idaho. The high humidity and high temperatures (77-95 degree days, 60+ degree nights) occurring this season are the conditions under which these issues often occur. Cercospora Leaf Spot Identification and Control Cercospora leaf spot manifests itself as individual, circular spots. The spots initially appear light tan with a reddish outline, but as the disease worsens the spots coalesce and turn to a dark brown. Eventually, leaves will fall to the ground and remain attached to the crown – robbing sugarbeet growers of optimal yield. To control Cercospora leaf spot, growers can turn to Inspire® XT fungicide. A combination of two trusted triazoles, Inspire XT provides a reliable, high level of Cercospora leaf spot control. Inspire XT offers quick rainfastness and flexible application options, easily fitting into any existing program. Black Bean Aphid Identification and Control Black bean aphids have pear-shaped, soft, olive green to black bodies with piercing/sucking mouthparts. They may or may not have wings, as explained by the University of Idaho. Symptoms include leaf curling and distortion (especially young leaves at the center of the crown) and leaf yellowing and wilting (first along the edges). Strong populations of beneficial insects can be helpful in managing this pest. The University of Idaho recommends that growers:

Conserve natural enemies (lady beetle larvae and adults, lacewing larvae and adults, hover fly, parasitic wasps) by learning to recognize them and managing foliar insecticides
Supplement food and habitat for natural enemies with “insectary plants” (alfalfa, buckwheat, clover, mint, vetch)

Alabama: Soybean Looper is on the Loose

SyngentaAgronomy — Mon, 19 Sep 2016 13:30:14 +0000

According to the Alabama Cooperative Extension, soybean looper numbers have been on the rise across the state. It’s during the larval stage that the soybean looper begins to cause damage on soybean plants. North Carolina State University research indicates the soybean looper seldom causes significant pod damage, but is capable of heavy foliage injury, which is equally detrimental to yields. Defoliation caused by the soybean looper can be identified by ragged leaves. Populations typically reach peak levels late in the season in August or September. To proactively monitor fields for soybean looper infestations, growers should scout for insect presence throughout the season. By scouting for soybean looper eggs and moths, growers can pinpoint the start of infestations and combat the pest before significant damage occurs. Louisiana State University researchers note soybean looper has developed resistance to certain insecticide chemistries, so effective control measures are primarily limited to lepidopteran-specific insecticides. Experts advise using local economic thresholds forsoybean looper to determine when treatment is necessary. When scouting indicates a need for treatment, Syngenta offers Besiege® insecticide, which provides excellent knockdown control of a broad spectrum of the most difficult-to-control lepidopteran pests, including the soybean looper. When applied, the long-lasting residual control found in Besiege protects plants through harvest, helping soybeans yield strong.

Evaluate Weed Management Performance Now

SyngentaAgronomy — Wed, 21 Sep 2016 20:35:01 +0000

Harvest is an important time for growers across the country to evaluate their weed control tactics. When growers are harvesting, they should thoroughly check the fields for weed pressures that may have taken a toll on this year’s yield. It's important to remember that weeds depend on routine to survive. Weed management programs that rely on one herbicide increase the potential for herbicide-resistant weeds to develop. As a result, the herbicides used to control these weeds may become ineffective. Therefore, it becomes vital to have a proactive weed management program to win the battle against troublesome weeds. A season-long weed management battle plan is essential to protecting your valuable crop investments. Deploy these tactics next season to avoid herbicide resistance and give your crops a fighting chance:

Use fully labeled herbicide rates
Diversify herbicide modes of action
Rotate crops in successive seasons
Overlap pre-emergence and post-emergence residual herbicides

Syngenta has a strong lineup of both pre-emergence and post-emergence corn and soybean herbicides. To combat weeds in corn, there is the dynamic duo of Acuron® or Acuron Flexi and Halex® GT herbicides.

Acuron defeats tough weeds current products are missing and delivers a step change in weed management with greater consistency of control.
Trials show that Acuron Flexi delivers improved control and more consistent control than competitive herbicide programs and can be used in states with atrazine restrictions.
Halex GT corn herbicide is the post-emergence partner of choice in a two-pass herbicide program. Survey shows 9 out of 10 farmers who try Halex GT use it again, making it the number one pre-mix post-emergence corn herbicide.¹

In soybean fields, Boundary® 6.5 EC or BroadAxe® XC herbicides provide strong pre-emergence protection, while giving flexibility in application timing. Combining this with Flexstar® GT 3.5 herbicide increases defenses to control stubborn weeds all season. Resistance management requires full-season attention. Don’t let weeds overtake your corn and soybean fields. Plan early for your 2017 herbicide program to control weeds, achieve higher yield and fight resistance all season.

Tomato Spotted Wilt Virus in Kentucky Tomatoes

SyngentaAgronomy — Fri, 23 Sep 2016 13:18:16 +0000

KENTUCKY: Kentucky Pest News reports that tomato spotted wilt virus (TSWV) has been more of an issue in Kentucky this year than in the past, especially in high tunnel tomatoes. Symptoms Common symptoms include:

Ringspots on leaves and/or fruit
Mottled and/or irregular fruit
Stem lesions
Leaf bronzing
Leaf stunting
Leaf wilting

Tomatoes exhibiting mottling, ringspots and irregular growth. Prevention Prevention is key to managing this pest, as there are no chemical management options available for plants once they’re infected with TSWV. TSWV is transmitted by thrips when they feed on an infected plant. When this happens, the virus replicates within the thrips and if they then feed on a healthy plant, the thrips may transmit the virus. Kentucky Pest News recommends the following prevention tactics:

Select disease resistant varieties
Do not set transplants that have visible spots
Utilize reflective mulches to deter thrips
Remove all above- and below-ground portions of infected plants; destroy to reduce disease spread
Manage weeds aggressively, both within and in close proximity to production areas
Manage thrips insect vectors

Resistant Varieties Selecting tomato varieties that are resistant to TSWV is a key step in preventing the disease. Syngenta offers a wide range of varieties that are resistant to TSWV, including BrickYard, Mountain Glory and SummerPick. More information about these varieties can be found here.

You Might Be in for Early Corn Harvest If…

SyngentaAgronomy — Wed, 28 Sep 2016 13:37:17 +0000

UPPER MIDWEST: Take a look at the list below. Growers who can relate to any or all of these factors could be in for an early harvest this year.

Rainy spring and corn planted after May 20
Little rain for three months after planting
Lots of rain in August and September
More than 20 days of temperatures greater than 90° during pollination
Used non-traited corn
Nitrogen leached away in in spring or late-summer rains
No fungicide applications
Corn was already at black layer in the middle of September
"Stalk push tests" indicate weak stalks

This year, there is a high risk of stalk lodging causing yield loss. For the reasons listed above, and many more, walking through corn fields over the next week or two will be critical for ensuring the best harvest – and best-timed harvest – possible.

AgriPro Wheat: From Field to Fork

SyngentaAgronomy — Wed, 28 Sep 2016 14:55:08 +0000

Wheat growers are familiar with every part of the growing process – from emergence, to tillering, to the final harvest. But what happens to the wheat once it is harvested? In honor of Whole Grains Month, Syngenta is exploring the journey of AgriPro^® brand wheat varieties from the field to the fork. AgriPro brand wheat varieties can be found across the U.S. – from the East Coast through the Northern Plains and Western Seaboard. Each class of wheat has characteristics that make it ideal for certain types of products. Trace the journey of key AgriPro varieties below: Hard red winter wheat Varieties including the popular SY Monument and SY Wolf, and the new SY Flint and SY Sunrise, grow well across the Central and Southern Plains. These are versatile varieties with excellent milling and baking characteristics. In fact, hard red winter wheat is commonly found in breakfast cereal or toast. It’s a staple in pantries and can also be found in tortillas and general purpose flour. Hard red spring wheat Found in the Pacific Northwest and Northern Plains, hard red spring wheat has high yield potential and excellent end-use quality. Varieties like SY Coho and SY Selway in the PNW, SY Soren and SY Ingmar in the Dakotas, result in grain that is excellent for croissants, bagels and pizza crusts. While a delivery pizza box might feature a well-known brand, the crust might feature grain from an AgriPro wheat variety. Soft red winter wheat Eastern regions of the country produce a bounty of soft red winter wheat like the new SY 100 and SY Viper. These varieties result in grain that populates snack aisles and school lunches in towns across America. With excellent milling and baking qualities, these varieties can be found in cookies, crackers and pretzels. Soft white wheat Another variety found in the Pacific Northwest and some Eastern regions is soft white wheat. A low-moisture wheat with high extraction rates, it can commonly be found in pastries and cakes. When growers harvest their high-performing varieties like SY 944, they could be harvesting the first ingredient in a birthday cake or a warm, glazed donut. Hard white wheat SY Teton is grown in the Pacific Northwest and features a high yield potential and good test weight. The high-quality grain from SY Teton can be found anywhere from Chinese takeout to Taco Tuesday. The grain from hard white wheat is used to make tortillas, Asian-style noodles and flat breads. AgriPro wheat varieties are everywhere – from the field to the fork. Next time growers are applying nitrogen treatments or scouting for weeds, remember that the end product may already be waiting at home – the perfect late-night snack after a hard day’s work.

Sample Soil to Stay Ahead of Phytophthora

SyngentaAgronomy — Tue, 04 Oct 2016 16:46:38 +0000

California soils are naturally infested with various species of Phytophthora, which tend to thrive in cool, wet conditions. The stress caused by this pathogen is compounded in the salty soils and water found in the state. With many areas seeing record rains earlier this year, tree fruit and nut growers are in a high-risk situation for this disease as the 2017 season approaches. Because strong, healthy root systems are essential to overall tree health and productivity, it’s important that growers establish an aggressive management plan for Phytophthora, which overwinters in soil. Most symptoms are commonly mistaken for drought, nutrient deficiency and salt burn, so soil sampling is key to detecting and controlling this pathogen. The Soil Pathogen Assessment (SPA) program from Syngenta helps make soil sampling easy and efficient. Since the threat of Phytophthora was high in 2016, and with more thought to be coming in on nursery stock, Syngenta will increase the number of samples it will accept in 2017 through the SPA program. Managing Phytophthora An integrated management system that includes cultural practices and a soil-applied fungicide during root flush (near bud break/leaf emergence) in the spring and fall is key to combating Phytophthora. Soil sampling and testing can be done beforehand to confirm presence if not previously known. Ridomil Gold® SL fungicide offers long-lasting disease protection against crown rot, collar rot and root rot caused by several Phytophthora species. Research results show larger root mass, tree weight and tree diameter when using Ridomil Gold SL in a Phytophthora management program.¹ Contact your Syngenta representative to learn more about soil sampling through the SPA program: www.Syngenta-US.com/rep-finder.

Yields Keep Seed Advisor Coming Back for More

SyngentaAgronomy — Tue, 04 Oct 2016 17:09:50 +0000

New Baden, IL: When Mike Laux first came out of college, he worked for a retailer selling multiple corn seed brands. In his eyes, it didn’t take long for one corn seed brand to outshine the competition: Golden Harvest® Corn. “I fell in love with the Golden Harvest Corn genetics so much I decided to start selling the seed,” Laux said. “I’m now going on my ninth year as a Golden Harvest Seed Advisor, and the yields keep getting better every year. The genetics are phenomenal.” Golden Harvest hybrid G10S30-3220 brand is a favorite for Laux, who also grows his own acres. The hybrid features the Agrisure Viptera® trait for earworm, cutworm and armyworm control, which are problematic pests in his area. “The hybrid is yielding in the 200 to 220 bu/A range,” Laux said. “With the Agrisure Viptera trait, I didn’t have any earworm issues so I didn’t need to worry about molds, either.” Golden Harvest® hybrid G10S30-3220 brand excels in highly productive management systems, offering superb stalk strength, outstanding yield potential and seedling vigor. While seed selection is key for Laux, he makes sure to protect his hybrids every step of the way, from planting to harvest. This year, he chose Acuron® herbicide for one-pass weed control. “This was my first year using Acuron as a single-shot herbicide, so I was nervous about spraying early in April. But wherever I used it, we had extremely good results and no weed issues in our fields,” he said. Laux also sprayed Trivapro® fungicide at R1 for disease management and stronger stalks. “Some of my neighbors had issues with corn blowing over, but I am very, very happy with the standability of my hybrids from the Trivapro application,” he said. “The combination of Golden Harvest Corn genetics and Trivapro is a winning one.” “I am extremely happy with my results,” Laux continued. “Syngenta is a top-notch company, and I have fallen in love with the seed and crop protection products they have to offer.” All photos are either the property of Syngenta or are used with permission.

A Seal of Approval from Fifth-Generation Farmer

SyngentaAgronomy — Wed, 05 Oct 2016 16:27:10 +0000

Remsen, IA: Jeff Pottebaum represents the fifth generation of farmers in his family, and this year marked his 27^th of growing corn. It hasn’t always been Golden Harvest® Corn, but after his local Golden Harvest Seed Advisor™ suggested several years ago that he give it a try, Pottebaum hasn’t looked back. Despite experiencing two heavy bouts of rainfall – one at planting and the other in August – as well as several windstorms and local threats from European corn borer, Pottebaum found himself grinning from ear to ear as he closed out the season with great yields. Golden Harvest hybrid G02W74 brand, a hybrid he’s been growing since 2013 because of its excellent stalk strength, emergence and moisture content, hit yields as high as 265 bu/A. “I plan to keep planting it until I’m proven wrong,” Pottebaum said. Remsen, Iowa grower Jeff Pottebaum had plenty of reasons to smile after his Golden Harvest Corn withstood two heavy bouts of rain.

As harvest continues for growers around Ohio, it also continues for Syngenta agronomists at the Marysville, OH, Grow More^TM Experience site. While Ohio growers may not have experienced as much pest pressure this season due to an early-season frost and low moisture levels throughout the summer, agronomists suggest still utilizing harvest time to evaluate their product performance. Derrick LeBeau, Syngenta agronomic service representative, tells area growers to pay attention to how clean rows are to evaluate weed pressure. He also recommends looking at leaf tissues in the middle of the rows when harvesting, because scars will still be visible if there was any disease this season. By evaluating the pressures the fields faced this year, growers will be able to make more proactive management plans for next season.

Harvest in Bay Brings Top Trial Results

SyngentaAgronomy — Wed, 05 Oct 2016 16:33:49 +0000

The Bay, AR, Grow More^TM Experience site faced challenging weather late this season. Long periods of wetness followed by extreme heat increased the presence of pests significantly throughout the region. As the site began harvesting in mid-September, the full impact of the Syngenta product portfolio became evident. According to Bay agronomists, some of the top results they are seeing this season are:

Trivapro® fungicide — Corn hybrids with Trivapro produced healthier-looking plants. With 3 active ingredients, including Solatenol®fungicide, Trivapro delivers long-lasting disease control and crop enhancement benefits to maximize yield potential.
Quadris Top® SBX fungicide — Soybean varieties with Quadris Top SBX had stronger disease protection compared to untreated plots. Quadris Top SBX is a powerful tool for soybean growers who want to maximize yields and deliver a return on investment while controlling powdery mildews and leaf spots.
Besiege® insecticide — Worm pressure in soybeans was high in the state, but soybeans treated with Besiege in Bay didn’t see this pressure. Besiege provides excellent knockdown and long-lasting residual of the most difficult-to-control lepidopteran pests and other economically important pests.

The Importance of Using Corn Fungicides

SyngentaAgronomy — Wed, 05 Oct 2016 16:45:24 +0000

When the market price of corn slumped in July, many growers decided not to use fungicides, or used lower cost products. The old saying “you get what you paid for” certainly applies this year, and most years. This season, many corn plants started senescence too early – beginning in mid-to-late August. Considering the corn plant is a factory running 24/7 with the ultimate goal of harvesting sunlight, and using water and nutrients from the soil to produce sugars to fill the kernels, keeping the plant factory green and healthy is critical to maximize yield. Diseases also played a big factor. Although northern corn leaf blight (NCLB) wasn’t as detrimental compared to last season, the plentiful rain did allow multiple disease problems to occur including rust, grey leaf spot and anthracnose. Without the protection of fungicides, this left the corn plants vulnerable to diseases. Trivapro® fungicide is the latest fungicide developed by Syngenta that provides the longest activity against the major diseases listed above. As the photo below taken just this week shows, the Trivapro-treated area of the field had superior disease protection, resulting in significantly healthier green leaf tissue and a longer grain fill window than the competitive treatment. Preserving the grain fill window will help grow more corn.

Arkansas Trial Helps Hold Off Frogeye Leaf Spot

SyngentaAgronomy — Thu, 06 Oct 2016 14:13:40 +0000

Frogeye leaf spot posed problems for Arkansas soybean growers this season. According to the University of Arkansas Extension, the disease thrives in warm and wet climates, and if not managed properly, the disease can cause severe yield loss. One of the stand-out trials this year at the Bay Grow More^TM Experience site tackled this disease with Quadris Top® SBX fungicide. Take a look below at some photos from the field to see how the strong performance of Quadris Top SBX stood up against frogeye leaf spot this season.

Even as Wind Blows, Golden Harvest Hybrids Stand

SyngentaAgronomy — Thu, 06 Oct 2016 19:30:38 +0000

Arlington, NE: Mother Nature may have her ways, but Luke Lauritsen has his Golden Harvest® Corn. Lauritsen’s family has been growing Golden Harvest for nearly 30 years, and for the past 10, he’s been selling it as a Golden Harvest Seed Advisor™. He was more than happy to have it this year, when the weeks leading up to harvest included late season disease pressure and rowdy weather, including an unexpected 8-inch rainfall. “We had a lot of wind late, but our new number this year – Golden Harvest hybrid G11F16-3111A brand – withstood 70 mile per hour winds standing fine,” Lauritsen said. “Meanwhile, some of the products we’ve seen from competitors were actually breaking off or falling over.” Luke Lauritsen’s family has been growing Golden Harvest Corn for 28 years. Lauritsen has also been loyal to NK® Soybeans, which he said have so far been yielding in the mid-60s to low 70s in his area. NK Soybeans S24-K2, S28-A2, S28-N6 and S34-P7 brands have been particularly popular with his customers, he said. All photos are either the property of Syngenta or are used with permission.

Exceeding Projections Makes for Happy Start to Harvest

SyngentaAgronomy — Thu, 06 Oct 2016 19:36:01 +0000

Sac City, IA: Harvest has hardly begun for grower Justin Bellcock, but his NK® Soybeans have already surpassed his expectations. So far, Bellcock said he’s seen NK Soybeans S21-M7 and S20-T6 brands yielding up to 75 bu/A, which he said is about 10-15 bu/A above average for his region. Bellcock attributed his success to implementing a high-yielding agronomic strategy that includes Syngenta products. By selecting solid NK Soybean varieties and protecting them with Clariva® Complete Beans seed treatment, a combination of separately registered products, Bellcock noted he has seen reduced soybean cyst nematode pressure and better standability over the years. “As far as I’m concerned, Syngenta has the best soybeans on the market,” said Bellcock, who is also a Golden Harvest® Seed Advisor™. “If you follow their high-yield soybean program, you’ll be happy.” Justin Bellcock said he’s been more than pleased with the start of his 2016 harvest.

Don’t Let Disease Dock Corn at the Elevator

SyngentaAgronomy — Fri, 07 Oct 2016 16:34:27 +0000

Pulling a full semi of corn into the elevator should be a time to bring in the big bucks. But some Illinois growers are getting hit with devastating dockage fees – up to 70% – for having such severe disease prevalence on their kernels. Diplodia, Gibberella and Nigrospora, or cob rot, are the top three disease corn growers are facing this harvest season. When crop scouting, make sure to inspect at least 10 ears across multiple locations before calling your field clean. Here’s how to identify if one of these diseases is an issue:

Diplodia: Diplodia is causing most of the disease damage for Illinois growers this year. Marked by a coating of white, non-toxic mold, the pathogen starts toward the bottom of the ear and works its way up. Diplodia can even be marked by white mold on the outside of the husk. Taking a closer look at Diplodia-infected grain and corn cobs, small black dots, signs of disease spores will be present. Although genetics play a role for this disease, weather is the greatest factor. High amounts of rain during early pollination increases the chances of Diplodia development.

Gibberella: While Diplodia is white, Gibberella is pink when the disease is fully developed. This disease works its way from the top of the corn ear to bottom. Spurred on by cool, wet weather during the first 21 days after silking, Gibberella mold can grow between the husks and ear, as well.

Nigrospora: Also known as cob rot, Nigrospora is deceiving because it can’t be detected from the outside. Rather, the cob is spongy, and the disease is brought on by a stress-induced environment, such as frost, drought, root injury, leaf blight or stalk rot. Since spongy cobs are more difficult to harvest, growers need to adjust their combines to maximize kernel removal and minimize cob breakup. This is best accomplished by finding the right combination of rotor speed and concave opening.

The corn ear on left is infected with Diplodia, while the ear on right is not. Rotating from corn to soybeans each year helps reduce the possibility of Diplodia disease outbreak. To prevent Diplodia, Gibberella and Nigrospora, rotate from corn to soybeans to break the cycle of pathogen buildup. When it comes to controlling leaf diseases, spray an application of Trivapro^® fungicide at R1, when necessary. With three active ingredients, including Solatenol^® fungicide, Trivapro delivers long-lasting disease control and crop enhancement benefits to maximize yield potential.

NK Soybeans Make for a Happy Family

SyngentaAgronomy — Fri, 07 Oct 2016 19:22:37 +0000

Kingsley, IA: For the Carlsons, raising row crops and hogs is a family affair. Even after Robert Carlson retired and his son, Tim, and grandson, Austin, split the work on the farm in half, all three generations still collaborate to ensure they make the best decisions for their family operation. Like many growers in northwestern Iowa, the Carlsons faced abnormally heavy bouts of rain in the spring that delayed their planting, as well as hail and windstorms. Fortunately, the rainfall that arrived in August helped their NK® Soybeans S26-P3 brand thrive. With just 10 or so days before harvest, the beans were standing strong and tall with large pods, and their fields were as clean as a pin. The Carlsons expect their yields to hit around 70 to 72 bu/A. “Our NK Soybeans stand great and are drying down quicker,” Austin Carlson said. “They’re just great.” Pictured from left: Austin, Tim and Robert Carlson, three generations of Kingsley, IA growers.

Long-Time Grower Finds Never Before Seen Yields with NK Soybeans

SyngentaAgronomy — Mon, 10 Oct 2016 13:17:36 +0000

Raymond, NE: In 35 years of farming, Kurt Schachenmeyer has never averaged 70 bu/A across all his soybean acres. NK® Soybeans got him over the hump. In 2015, his fifth season growing NK Soybeans, Schachenmeyer turned to NK Soybeans S34-N3 brand, a widely adapted medium-bush plant with excellent stress tolerance. It met the top qualities he said he looks for in beans – standability and yield – and it definitely didn’t let him down. After averaging more than 70 bu/A last year, Schachenmeyer planted it in 100 percent of his fields this year. His harvest is only just beginning, but in the one field he’d combined so far, the monitor showed 68 bu/A – another promising start. Stay that way, he said, and he’ll probably go all in on S34-N3 brand yet again in 2017. NK Soybeans S34-N3 brand’s high yields and excellent standability have translated to new yield averages for longtime grower Kurt Schachenmeyer.

In Competitive Face-off, a Favorite Emerges

SyngentaAgronomy — Tue, 11 Oct 2016 13:44:03 +0000

Brainard, NE: Like many soybean growers, Jerome and Todd Kudlacek diversify risk and analyze crop quality by planting several brand varieties. This year, the Kudlacek brothers are comparing competitor varieties from NK® Soybeans and Asgrow®. “This is our third year growing NK Soybeans, and we especially like the brand’s standability, harvestability and yields,” Jerome Kudlacek said. “Compared to Asgrow, NK Soybeans yield better, and we also like the quality of harvestability a bit better.” Todd Kudlacek added, “The NK Soybeans seem to flow through the combine more smoothly, and there isn’t nearly as much trash.” NK Soybeans currently make up about 35% of the Kudlaceks’ soy acres, with NK Soybeans S34-N3 and S35-A5 brands being two of their favorites. The Kudlaceks said they appreciate that the NK varieties are flexible enough to work well on both their bottom ground and hillier acres. Brothers Jerome (left) and Todd Kudlacek found that NK Soybeans delivered better yields and harvestability than the competition. They’ve already finished harvesting S34-N3 brand and were pleased to find it yielding an average of 70 bu/A, with the combine monitor hitting as high as 107 bu/A. Their S35-A5 brand fields are still on the harvest to-do list, but they expect good things. Part of their confidence comes from the fact that they protected their NK Soybeans with CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products. “It’s a standard procedure for us to apply a seed treatment,” Todd Kudlacek said. “We want our soybeans to get off to a good start, and we can tell that (treated soybeans) have better plant vigor.” Jerome Kudlacek credited CruiserMaxx Beans with Vibrance with retaining the soybeans’ genetic potential. “Bean leaf beetle and early damping-off are two issues we face early in the season,” he said. “An application of CruiserMaxx Beans with Vibrance is a nice attribute for our soybeans.” All photos are either the property of Syngenta or are used with permission.

These Aren’t the Soybean Yields of 1903

SyngentaAgronomy — Wed, 12 Oct 2016 21:28:24 +0000

Mead, NE: Ben Deerson may be impressed with his NK® Soybeans S30-C1 brand yielding 81 bu/A this year – but not as impressed as his late great-grandfather, the founder of his family’s farm, probably would have been. “My Great-Grandpa Deerson was born in 1903. He wouldn’t have believed I yielded as high as mid- to upper-90 bu/A this harvest,” he said. “Soybeans were a secondary crop back when he was farming, but today’s growers can control weeds much better, and genetic breeding has greatly advanced, too.” Grower Ben Deerson has seen solid yields out of his NK Soybeans this fall. He is confident this field of NK Soybeans S34-P7 brand will continue the trend. Deerson said he has relied on NK Soybeans for the last 10 years because of the strong variety lineup, and said his entire farm is better because of the genetics. In addition to growing his own acres, he is also a Golden Harvest® Seed Advisor™ serving growers in his area. “Not only are the NK Soybean varieties solid, but they also perform well against competitors,” Deerson said. “I ran a competitive test plot right here in Mead, and NK Soybeans S30-C1 brand outyielded Pioneer P31T11R brand by 19 bu/A and Asgrow 2733 brand by 18 bu/A.” Great-Grandpa Deerson would be proud.

Husband-wife Duo Get Ahead of the Game

SyngentaAgronomy — Fri, 14 Oct 2016 13:56:49 +0000

Madrid, IA: It’s been an efficient harvest for Larry and Franki Williams. In-between attending their grandchildren’s many sporting events, the husband-and-wife team has already harvested 80-85% of their fields, and they plan to take advantage of every sunny day ahead to get the remaining crops out of the ground. It helped that it was a relatively smooth growing season. Although they experienced soybean cyst nematode (SCN) pressure, the Williams’ fields received an ideal amount of rainfall this year and overall saw relatively low pest pressure. The results – Golden Harvest® Corn hybrids averaging more than 200 bu/A and NK® Soybean varieties averaging more than 60 bu/A – have left them thrilled. The Williamses grew Golden Harvest hybrids G06N80-3111, G07F23-3111, G09E98-3122 E-Z Refuge and G14R38-3000GT brands this year. “All of our hybrids have been in that ballpark this year,” Franki Williams said. “They have good stalk strength and have all, for the most part, had uniform yields.” From a soybean perspective, the Williamses planted NK Soybean S22-S1 and S26-P3 brands and saw better yields this year than last. They credit that in part to using Clariva® Complete Beans seed treatment, a combination of separately registered products, which offers season-long protection against SCN. “I used Clariva Complete Beans seed treatment on all of my soybeans this year, and they had great standability throughout the season,” Larry Williams said. “I am a big believer in rotating fields, planting resistant varieties and using seed treatments to fight SCN and sudden death syndrome.” Approaching retirement, the Williamses feel confident in their seed choices and in being ready to hand over the duties to the next generation in the near future. Not that every season will always be quite this straightforward. “Mother Nature can deal you any cards she wants,” Larry Williams said. Larry (pictured) and Franki Williams are already close to wrapping up their 2016 harvest after a solid growing season. Preparation was key. “We always do our best to prep for a season where the cards aren’t in our favor,” Larry Williams said. While combining Golden Harvest hybrid G06N80-3111 brand, Franki Williams noted that the yield monitor reached as much as 15 bu/A above the region’s typical average. “We’ve been amazed by the corn this year,” she said.

Grower Achieves New Yield Mark Despite Tough Conditions

SyngentaAgronomy — Mon, 17 Oct 2016 18:44:09 +0000

Anna, IL: Breaking your own record is always exciting, but it’s even more so when it comes at the end of a tricky six months. Illinois soybean grower Mark Willmann just experienced that sense of accomplishment, bringing in his best-ever soybean yields with NK^® Soybeans S42-P6 and S39-C4 brands. “I averaged 72 bu/A in a 90-acre field with these two varieties, and that’s counting the edge rows, which usually don’t yield as well,” Willmann said. “I even saw the yield monitor hit more than 100 bu/A for a brief moment.” These yields would have been impressive for Willmann in a season with great weather. This year, however, was far from perfect – if anything, it was an uphill battle from the start. “Our beans laid under water for two weeks before coming up. We had a very wet – much too wet – season in general,” said Willmann, who in addition to growing his own crops is also a Golden Harvest® Seed Advisor^™. He is a firm believer in protecting his NK Soybeans with Clariva^®Complete Beans seed treatment fungicide/insecticide, a combination of separately registered products. “The weather is never perfect around here, so Clariva Complete Beans is a form of insurance,” Willmann said. “If we didn’t use it, we’d have Phytophthora and emergence issues from excess water. But with the Clariva Complete Beans treatment, our crop nearly jumped out of the ground.” Mark Willmann said the best part about farming is watching things grow, which he saw his NK Soybeans do plenty of this season.

Nebraska Retailer Says NK Soybeans Pay Off in Bushels

SyngentaAgronomy — Tue, 18 Oct 2016 18:51:20 +0000

Hallam, NE: The most rewarding part of Ryan Franzluebbers’ job as a Farmers Cooperative site manager is helping his growers find agronomic solutions to be successful. The NK® Soybeans portfolio plays an important part to help meet his customers’ needs. “I’ve been working with NK Soybeans ever since I started with Farmers Cooperative six years ago,” Franzluebbers said. “Growers usually see a 3-5 bu/A yield increase when they switch to NK Soybeans over their previous programs.” He said NK Soybeans continue to perform well in the face of adversity because of the varieties’ strong agronomic packages and ability to yield consistently. “NK Soybeans S34-N3 and S35-A5 brands contain industry-leading genetics so they continue to provide outstanding yield in tough conditions. They also handle our variable clay and gumbo soils very well,” he added. Ryan Franzluebbers has counted on NK Soybeans since he first started with Farmers Cooperative six years ago. “The products are excellent, and I like working with the Syngenta reps,” he said. Growers in Franzluebbers’ territory often struggle with early-season grasshoppers, Phytophthora root rot and damping off. To maximize yield performance, he recommends that soybean growers protect their investment with CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products. “Soybeans treated with the CruiserMaxx Beans with Vibrance seed treatment stand much better,” Franzluebbers said. “It has proven to be the leading soybean treatment year in and year out.” All photos are either the property of Syngenta or are used with permission.

For Love of Family – and Driving the Combine

SyngentaAgronomy — Wed, 19 Oct 2016 21:17:35 +0000

Webster City, IA: Gary Gourley may be 86 years old, but each harvest, you’ll still find him taking the lead for the hog and row crop farm that he runs with his three sons. “I could retire, but I love helping my boys out,” Gourley said. Sitting behind the wheel of the family’s combine allows him to keep a pulse on everything happening in the fields. “I just love driving machinery – done it all my life. I can relax here,” he said. Back in the driver’s seat, Gourley switched on autopilot and flipped through a binder of yield data to show just how good a season 2016 has been for his family’s operation and their NK® Soybeans. NK Soybeans S20-T6 brand, in particular, went above and beyond expectations, yielding up to 85 bu/A. Despite a cooler spring that impacted emergence, heavy winds and some hail damage, Gourley’s NK Soybeans stood tall and yielded strong. “The soybeans have just been excellent this year,” Gourley said. At harvest time, there’s nowhere else Gary Gourley would rather be than in the cab of the combine. All photos are either the property of Syngenta or are used with permission.

Water-Optimized Hybrids Shine in Wet Conditions

SyngentaAgronomy — Thu, 20 Oct 2016 16:58:42 +0000

Ettrick, WI: Recent rain slowed down many growers’ harvest in the western part of Wisconsin this year. Thanks to his Golden Harvest® Corn, Ken Zeigler has been able to move full steam ahead despite the weather Mother Nature sent his way. “Our sandier soils really helped us this year,” said Zeigler, whose farm is located just 30 miles east of the Mississippi River. “The weather was in our favor with the type of soils we have, and that’s helped us to average more-than-200-bushel hybrids.” Zeigler planted Golden Harvest G07B39-3111A brand, an Agrisure Artesian® hybrid designed to maximize yield when it rains and increase yield when it doesn’t. Artesian™ hybrids are built to be solid performers regardless of the weather conditions. So far, Zeigler has recorded yields as high as 250 bu/A. After a wet season, Ken Zeigler’s yields benefited from his Artesian™ hybrids’ ability to maximize yield when it rains. All photos are either the property of Syngenta or are used with permission.

Investing in Strong Hybrids Prepares for Mother Nature’s Curveballs

SyngentaAgronomy — Fri, 21 Oct 2016 18:29:04 +0000

Nevada, IA: From growing season to growing season, one thing is constant: Mother Nature will deal unpredictable, game-changing cards that force growers like Jerry Linn to expect the unexpected. “She’s a huge obstacle to overcome,” Linn said. “You have to guess where she’s going to lead you and hope she’s kind to you.” Fortunately, Mother Nature did prove kind to Linn this year. His corn received just enough rain in June to establish deep and strong roots that were able to withstand the persistently wet months that followed. Linn also prepared his fields by planting hybrids with strong standability ratings like Golden Harvest® hybrid G02W74-3000GT brand. Featuring the Agrisure® 3000GT trait stack for protection against corn borer and corn rootworm, the hybrid yielded 207 bu/A, he said. “If you can plant a hybrid with different levels of protection that will benefit your own system, do it,” Linn said. “While growers often go to conventional corn because it’s cheaper, they’re shooting themselves in the foot. Spend a little bit more money up front. It’s like insurance and money in the bank.” For Linn’s 2016 growing season, the result of that investment was a hybrid that delivered stalks that “stood like picket fences” and grain that “combined like butter.” “The standability (of G02W74-3000GT brand) was fantastic – I can’t knock it. I will keep planting this variety until I find something better,” he said. “I haven’t found anything better.” Jerry Linn entrusted Golden Harvest hybrid G02W74-3000GT brand to withstand whatever Mother Nature would throw his way, and it didn’t disappoint. Linn’s three 12,000-bushel grains bins are nearly full. All photos are the property of Syngenta or used with permission.

Illinois Corn Update: Ear Molds, Weeds & Yields

SyngentaAgronomy — Mon, 24 Oct 2016 19:59:58 +0000

ILLINOIS: The past three months saw above average temperatures and rainfall which usually has an effect on the corn crop. Experts are seeing lower than projected yields, ear molds and more weeds than expected. Here are the numbers according to the National Weather Service in St. Louis: July:

Rainfall was 8.37” total which is 4.26” above normal
Low temperature was 2.1 degrees above normal at 73.1 degrees
High temperature was .9 degrees above normal at 90.0 degrees
July 2016 was the fourth wettest on record and had 28 days where the low temperature was above 70 degrees

August:

Rainfall was 5.77” which is 2.78” above normal
Low temperature was 3.1 degrees above normal at 72.5 degrees
High temperature was 1 degree above normal at 88.9 degrees
August 2016 was the 11^th wettest on record and is tied with the 20^th warmest on record

September:

Rainfall so far has been 4.82” which is 2.22” above normal
Many areas have seen much more rain locally
The month finished with both high and low temperatures above normal, as well

So what do these numbers mean to a corn crop?

Above average night time temperatures are associated with higher respiration rates in the corn plants. Respiration uses sugars formed from photosynthesis during the day, leaving less sugars and energy available for grain fill. Additionally, higher temperatures speed up corn maturation leaving less time for grain fill. Cooler temperatures, especially nighttime temperatures, result in a longer grain fill period, less energy loss and higher yields.

Ear molds are always more likely to occur as a result of above average moisture during the grain fill process. During periods of high rainfall and humidity, heavy overnight dews are common and ear molds have excess moisture available for continued development. Insect feeding on the ear tips can worsen this condition. Sprouting of kernels is a common sight as well this year. More information about Diplodia ear mold can be found here.

Ample moisture and warm temperatures moved the corn crop along quickly. Nitrogen loss was also a factor in some fields. A severe infestation of Southern Rust was also present. Similar symptoms of nitrogen deficiency, disease and crop maturity caused green leaf tissue to disappear in August, more sunlight broke through the crop canopy reaching the soil.

Because of excessive moisture conditions, weeds were able to emerge giving fields a “weedy” appearance after harvest. Two key points to consider are how long the herbicides had been out in the field and the continual breakdown of those herbicides that occurred due to the above average rainfall and temperatures throughout the last 90 days. Usually plenty of moisture and warm temperatures are a good thing for corn crops, however during the summer of 2016, there were no real breaks in the weather pattern to offer any relief to the crop which forced it to use up more energy than normal in overnight recovery. Constant high moisture allowed ear molds to set in and cause damage and herbicides were tested to the extreme throughout the growing season.

Proven Reliability Earns NK Soybeans Brand Loyalty

SyngentaAgronomy — Mon, 24 Oct 2016 21:34:04 +0000

Erie, IL: Jerry Norman and his family have worked the same land since 1932, the first 60 years as tenants and the past 24 as owners. Of course, there have been many advancements in production tools and practices during that time span. “We can pull more crop out of one acre than they could in tens of acres. It’s just amazing how things have changed,” Norman said. Since the 1980s, however, at least one thing has remained constant: NK® Soybeans. “We’ve been growing them for about 30 years,” Norman said. “We’re really happy with the reliability (of the crops) and the input I get from the people at Syngenta to match the crop to my soil.” This is important considering the range of soil types found on his farm, which include light, irrigated sand; peat; and different combinations of the two. Jerry Norman continues to be happy with his decision to grow NK Soybeans, with no end in sight. “I will stay 100% with Syngenta products based on what I’ve seen this year,” he said. Beyond seed purchase considerations, Norman relies on his Golden Harvest® Seed Advisor™ and Syngenta sales representative to help him make decisions about seed treatments, too. That’s been particularly important in recent years, with soybean cyst nematodes on the rise. “We definitely have soybean cyst nematode problems (in the area). As the soil varies from one field to another, it shows up,” Norman said. “Clariva® Complete Beans seed treatment has definitely helped with that. It’s not even a concern of mine anymore.” The impact of treating seeds with Clariva Complete Beans, a combination of separately registered products, showed up in this year’s yields, with numbers about 10 bu/A higher than his yearly average. “I will stay 100% with Syngenta products based on what I’ve seen this year,” Norman said.

Selecting Hybrids by Soil Type Helped Illinois Yields

SyngentaAgronomy — Tue, 25 Oct 2016 17:00:11 +0000

Mounds, IL: Ryan Britton knows no two soil types are the same. At nearly 3,000 acres, his farm alone includes droughty, sandy and clay soil types. Given those conditions, Britton went into 2016 planting an array of Golden Harvest® Corn hybrids tailored for different soils. The approach worked: across his acres, he recorded average yields of 230 bu/A. Britton has been loyal to Golden Harvest since a competitive trial 12 years ago. “We compared against Pioneer®, DeKalb®, Southern FS® and Agrigold®,” Britton said. “The Golden Harvest products worked better for our operation.” This year’s standouts were Golden Harvest G14H66 and G12J11 brands, both of which are Agrisure Artesian® hybrids designed to withstand the test of unpredictable weather and stressed soil. Artesian™ hybrids maximize yield when it rains and increase yield when it doesn’t. Britton takes great pride in being an American farmer and helping others get the most out of their acres as a Golden Harvest Seed Advisor™. Active in his community, he works to take his desire to turn something small into something grand and pass it on to his children and those in his local 4-H Club and FFA chapter. “I enjoy taking something from a seed to a beautiful crop,” he said.

‘Best Beans in the Business’ Hold Off Diseases

SyngentaAgronomy — Tue, 25 Oct 2016 21:34:27 +0000

Avalon, WI: Sudden Death Syndrome (SDS) has grown to be a real challenge for growers across the U.S. In 2016, more than 50% of major soybean-producing states reported symptoms of the disease. Although the area in which Scott and Dustin McGinnis farm was affected, the performance of their NK® Soybeans remained remarkably steady. In fact, it has proven to be a solid soybean year for the McGinnises, who relied primarily on NK Soybeans S20-T6 brand, which offers strong resistance to SDS in addition to being an industry leader in Sclerotinia white mold resistance. Despite accounts of both SDS and white mold pressure in the area, the McGinnises’ yield monitor hit as high as 70 bu/A. That’s comparable to the previous year and high for the region, they noted. “Syngenta just has the best beans in the business,” Dustin McGinnis said. In addition to growing NK Soybeans, Dustin and Scott McGinnis (from left) serve as Golden Harvest® Seed Advisors™ in their area. All photos are the property of Syngenta or used with permission.

Bushels for the Grower, Enzymes for the Ethanol Plant

SyngentaAgronomy — Thu, 27 Oct 2016 13:19:59 +0000

Tomah, WI: Although Enogen® Corn may be known for its unique characteristics, to grower Arlen Simonson, it’s also simply a great crop. “No matter where we planted it, the Enogen corn just looks good,” Simonson said. “I love it.” Enogen corn enzyme technology is an in-seed innovation available exclusively from Syngenta, featuring the first biotech corn output trait designed to enhance ethanol production. It offers alpha amylase directly in the grain, eliminating the need for ethanol producers to source liquid amylase and keeping the dollars they would spend elsewhere in their local communities instead. Growers, meanwhile, are eligible to earn up to a 40-cent-per-bushel premium for Enogen grain delivered to participating ethanol plants. Simonson said he takes pride in being able to be an enzyme supplier for his ethanol plant and making a difference locally. The yields don’t hurt, either: Although it was still early in his harvest when the Harvest Chasers met with him, Simonson had already seen Enogen hybrid E092T4 brand yield 240 bu/A – a solid number in his book. Combining his fields on a sunny October day, Arlen Simonson recalled one of his grandfather’s favorite sayings: You can only grow one thing at a time – corn or weeds. “It would be awesome for him to see today’s yields,” Simonson said.

Beware of Bacterial Leaf Streak in 2017 Corn

SyngentaAgronomy — Thu, 27 Oct 2016 18:35:12 +0000

Delaware: Although bacterial leaf streak (BLS) has been detected in nine states, it has not been detected east of Illinois. Despite this, corn growers in Delaware should be on the lookout for this disease in 2017. According to the University of Delaware Extension, little is known about the disease cycle of BLS. Experts do know that the disease is caused by a bacterium, Xanthomonas vasicola pv. vasculorum. Based off this, they assume that the pathogen may overwinter in corn debris or volunteer corn and that the spread of the pathogen likely occurs through irrigation, flooding, and heavy rain/wind events.

Hunt for Innovation Drives Adoption of NK Soybeans

SyngentaAgronomy — Fri, 28 Oct 2016 13:12:38 +0000

Dahinda, IL: With each new year comes a unique new challenge – a challenge that Grant Strom always gladly accepts. “I enjoy competing against myself to push me to the best of my ability,” Strom said. “I take farming to heart.” One way that Strom continues to up his game is by seeking out innovation. It’s what led him to NK® Soybeans four years ago, and it’s what’s kept him growing it ever since. This year, his NK Soybeans S30-V6 brand yielded an average of 73 bu/A, exceeding even his own expectations. “The increase in soybean technology is incredible,” he said. Grower and Knox County (IL) Farm Bureau President Grant Strom has become a big proponent of NK Soybeans. After four years growing the brand, he is now convincing others in his area to try it, too. Strom attributes Clariva® Complete Beans seed treatment, a combination of separately registered products, to his success. In side-by-side trials on his farm, Strom found that soybeans treated with Clariva Complete Beans were less impacted by diseases such as Phytophthora, white mold and seedling blight. He also saw an increase in standability and yields. “There is no such thing as a perfect-standing bean, but the seed treatment is a form of insurance for us,” Strom added.

Agrisure Artesian Stands Out on SD Soils

SyngentaAgronomy — Mon, 31 Oct 2016 18:27:09 +0000

Britton, SD: For Lee Schneider, farming runs in the family. After graduating from South Dakota State University in 1980, Schneider joined his father on their century-old farm raising beef cattle, and growing corn and soybeans. “We have around 300 acres of corn, 600 acres of soybeans and 100 head of cattle, so I stay pretty busy,” Schneider said with a chuckle. Schneider has worked with his Golden Harvest® Seed Advisor™, Renny Tank, for 25 years. It all started with a single bag, but now he plants 100% Golden Harvest Corn and NK® Soybeans. He was still in the middle of harvest when the Harvest Chasers caught up with him, and while he didn’t have yield results yet, he was particularly impressed with his Agrisure Artesian® hybrids, which maximize yield when it rains and increase yield when it doesn’t. They appeared to have thrived despite a drought earlier in the season, even in some of his more difficult soils. “This is my second year with Artesian™ hybrids, and I definitely see a benefit to them,” Schneider said. “I’m a real promoter of them, especially for gumbo or salty ground.” Lee Schneider has been farming for more than three decades and today grows exclusively Golden Harvest Corn and NK Soybeans.

Careful Management Makes All the Difference at Harvest

SyngentaAgronomy — Wed, 02 Nov 2016 16:57:28 +0000

Seymour, WI: Harvest in many parts of Wisconsin has proven to be no easy task, but with the strengths of NK® Corn at full display, retailer Zac Soltvedt has been able to keep a positive perspective. “We have seen many of the NK Corn hybrids yielding top of the line with competitors,” Soltvedt said. The best results are coming from fields where growers closely manage their crops. Preventative maintenance, he said, can have a big impact on yields. With a range of soil types and microclimates in Wisconsin, Soltvedt said he advises his customers to make sure they really know their fields’ properties and local conditions when selecting seed. For example, growers who have fields with dense clay soils should be sure to plant hybrids with fibrous roots. NK Corn hybrids N31H-3000GT and N35T-3110 brands have been particularly effective in Wisconsin’s clay soils, he said. “This year’s yields are starting to stack up to be better than last year’s,” Soltvedt said. Taking a prescriptive approach to planting and careful management throughout the season can translate into better yields at harvest.

Grower Sees Strong Yields Despite Soaked Surroundings

SyngentaAgronomy — Thu, 03 Nov 2016 17:09:16 +0000

Zearing, IA: Growing conditions in central Iowa weren’t exactly ideal this season, and with saturated, wet soils from start to finish, harvest was no piece of cake. Despite this, Keith Frohwein was extremely pleased with his crops’ performance. “I’m really happy with the genetics of my Golden Harvest® Corn. It looked good all year,” he said. Frohwein had just finished harvesting Golden Harvest hybrid G02W74-3000GT brand, which averaged more than 200 bu/A with 15% drydown, when the Harvest Chasers caught up with him. He had a similarly positive experience with NK® Soybeans S20-T6 brand, which he protected with Clariva® Complete Beans seed treatment, a combination of separately registered products. With yields around 55 bu/A, Frohwein plans on continuing to treat his soybeans with Clariva Complete Beans next year as well. “The soybeans looked a little taller and a little bushier, and the yields were better,” Frohwein said. As a Golden Harvest Seed Advisor^™, Keith Frohwein applies his knowledge of corn hybrids and soybean varieties – plus his understanding of local soil and environmental conditions – to place the best-suited products that help his fellow growers succeed.

Problematic Winter Annual and Perennial Weeds are Germinating

SyngentaAgronomy — Mon, 07 Nov 2016 16:35:32 +0000

Missouri: Although it’s tough to look ahead to 2017 while the 2016 harvest is still wrapping up, it’s important to recall some problematic weeds from this past spring. Both marestail (horseweed) and curly dock (sour dock) have put herbicides and tillage equipment to the test, with many fields requiring separate in-field herbicide applications to try and regain control over these species. Now is the ideal time to control these two tap-root weeds, along with other winter annual weeds that are germinating strong with the recent moisture and above average temperatures, to simplify efforts next spring. When it comes to perennial plants like curly dock and dandelion, fall applications provide the ideal timing for systemic herbicides like glyphosate and 2,4-D/dicamba to pull down into the taproot as these plants move nutrients and carbohydrates into their roots for winter survival. Oftentimes, growers can attempt to kill these plants in the spring with contact products that kill above-ground plant tissue without actually killing the root; therefore, regrowth occurs. Since marestail will continue to germinate well into early spring, lack of control of the fall/winter germinated weeds can pose the biggest issues come a wet spring. Eliminating the first flush that’s in a rosette growth stage is advantageous versus battling spring bolting plants. Although it’s only November – don’t wait until right before frost for more weeds to emerge. It’s been observed time and time again that when rainfall occurs in the fall and fall applications don’t occur, it leads to a more challenging spring for controlling these weeds. A little added residual herbicide could go a long ways from now until winter. Check out the links below for more specific technical recommendations for fall marestail control in glyphosate-tolerant (GT) and LibertyLink soybeans:

Strong Roots Stand Up to Strong Winds

SyngentaAgronomy — Mon, 07 Nov 2016 22:50:21 +0000

Northern Knox County, IL: Looking around Tim Main’s acres, only a few things stood taller than his Golden Harvest® Corn: dozens of wind turbines. Driven by his battle against the bracing winds and strong storms that blow through his fields, Main is a strong proponent of technological advances. He is thankful for the way modern innovations, including advancements in genetics and breeding, have improved his ability to produce quality crops and increased yields to levels his grandfather would have never imagined. One innovation that helped to make his 2016 harvest a success was Golden Harvest hybrid G14R38. Its superb root strength and proven stalk strength serve conditions like Main’s quite well, and is built to withstand a range of insect pest pressures. The end result? Corn yields anywhere from 220 to 270 bu/A,” Main said, another good haul for a tough environment. Tim Main’s acres are nestled between rows of wind turbines – a visual reminder of the weather conditions he faces each year. All photos are either the property of Syngenta or used with permission.

NK Corn and Soybeans Overcome Consistently Wet Weather

SyngentaAgronomy — Tue, 08 Nov 2016 21:37:56 +0000

Appleton, WI: The fact that Ned Schwalbach had to seek shelter in his garage while meeting with the Harvest Chasers pretty much summed up his growing season. Some parts of Wisconsin saw rainfall in September that broke 20-year records. In Appleton, more than 5 inches of rain accumulated, exceeding the average by more than 2 inches. “We had rain from June 1 through the end of the season,” he said. “It just hasn’t stopped.” Seed selection is truly put to the test when dry days are scarce, and this season confirmed Schwalbach’s choice to grow NK® Corn. For example, NK hybrid N35T-3110 brand, a broadly adapted 95-day hybrid with superb stalk strength, ended up yielding as much as 225 bu/A on Schwalbach’s farm. Meanwhile, with its strong disease tolerance, his NK Soybeans S17-B3 brand were able to dodge some of the tougher diseases caused by this year’s moist conditions, yielding as high as 70 bu/A. While Schwalbach saw neighbors battle white mold, he was pleased to report his fields were not impacted by the fungal disease.

Weed Resistance: Looking Back on 2016

SyngentaAgronomy — Wed, 09 Nov 2016 14:47:54 +0000

This spring, researchers warned that weed presence and herbicide resistance were likely to be strong in 2016. With heavy rainfall in 2015 across the Midwest and some parts of the South, herbicide applications were often delayed or abandoned, and weed seeds were expected to spread to new areas as a result of flooding. The impending threat of herbicide-resistant weeds required an integrated management approach. This approach included employing both cultural practices and multiple herbicide modes of action to minimize the spread of weeds and resistance development. Trey Koger, a grower from Melzoni, MS, compares soybean production system to a 10-story building. Without a good pre-emergence herbicide to control weeds, he says growers will get stuck on the first or second floor. Koger was able to find success this summer despite the threat of glyphosate-resistant Palmer amaranth invading his fields. When Palmer amaranth came along, he started using Boundary^® herbicide as a pre-emergence herbicide and has been doing so for the last three years because of its good Palmer amaranth and annual grass control. Trey Koger on his farm in Belzoni, MS. This past season, it was vital for growers to stay vigilant by applying properly timed post-emergence herbicides to keep weed populations low. These proactive steps reduced weed seed bank buildup and delayed the onset of herbicide resistance for many growers across the Midwest and the South. Since waterhemp grows so fast, and it’s gained so much resistance, it’s hard to stop it once it’s taller than 3 to 4 inches. The residual component in Flexstar^® GT 3.5 herbicide helps hold waterhemp down. Using Boundary followed by Flexstar GT 3.5 delivers multiple modes of action for effective waterhemp management. Because herbicide-resistant weeds can become a serious problem soon after arriving in a field, an integrated weed resistance management approach is key. For next season, Syngenta and the United Soybean Board recommend:

Planting soybeans in narrow rows with higher seeding rates to help spread canopy coverage and shade out weeds.
Applying a pre-emergence residual herbicide. This helps young soybean plants to establish their full yield potential in a weed-free environment.
Applying a herbicide with two different modes of action that target the same species to help combat resistance and effectively manage weeds.
Being timely with post-emergence herbicide applications – weeds like Palmer amaranth grow rapidly, so there is a narrow window of opportunity to effectively treat the weed with a post-emergence herbicides.
Cleaning farm machinery to prevent the dispersal of weed seeds.
Minimizing the seed bank by keeping fields, ditches and turn rows clear of weeds that could go to seed.
Planting cover crops after harvest and use tillage, if necessary.

Weather Conditions and Yields Surprise WI Grower

SyngentaAgronomy — Wed, 09 Nov 2016 19:53:38 +0000

Greenville, WI: Harold Ellenbacher hoped 2016 would offer a dry growing season – but as soon as the summer hit, so did the rain. More than 6 inches of rain fell in June alone. “A lot of people’s crops flooded out,” Ellenbacher said. “Everyone thought that it was going to be a drought year, but Mother Nature proved us wrong.” Despite the heavy moisture, NK® Soybeans S20-T6 and S17-B3 brands offered a bright spot. In at least one field, the varieties got down to 14 percent moisture even with all the rain. With the strong standability and plant health that he saw this year, Ellenbacher noted, “It seems like the beans, year after year, are pretty consistent.” The performance of his NK Soybeans was a relief for the busy farmer, who in addition to growing row crops, also manages cattle. “We keep growing NK because we’re sold on the varieties and the company,” he said. “The service and the technologies help keep us around, too.” Harold Ellenbacher recounts his rainy, yet productive growing season with NK retailer Zac Soltvedt, NK sales rep John Crispin and the Harvest Chasers.

Developing Effective Corn Herbicides

SyngentaAgronomy — Thu, 10 Nov 2016 15:42:20 +0000

Developing effective corn herbicides starts with understanding growers’ needs. Weed control has long been a challenge across the Corn Belt, with weed resistance continually increasing. Anticipating needs is key to staying ahead of the challenges Mother Nature creates. Syngenta identified the need for a new weed control option in the early 2000s and started developing Acuron® and Acuron Flexi corn herbicides. Research is key to innovation. During the research phase of Acuron and Acuron Flexi, Syngenta’s team of 15 chemists were focused on finding a solution to deliver a greater level of weed control than other powerful herbicides such as Lexar® EZ and Lumax® EZ. Their best results combined mesotrione with bicyclopyrone, and after adding S-metolachlor and atrazine, the combination worked together as a pre-mix to control the toughest weeds in corn. The next step is to test the product. Lab tests and production trials helped ensure the Acuron would perform as growers expected. Then, the Acuron formulation was submitted to the EPA in September 2012. Syngenta’s focus then shifted to collaborating with universities and distributors to further test the herbicides under crop destruct protocols, beginning in 2013. To date, Syngenta has conducted 986 field trials on Acuron. Since receiving EPA registration on April 24, 2015, Acuron has delivered on its promise to control the toughest weeds in corn. Syngenta’s work didn’t stop with Acuron, though. They knew the importance of providing growers with options which led to the development of Acuron Flexi, a pre-mix of bicyclopyrone, mesotrione and S-metolachlor. It’s an excellent weed control solution in areas limited from using atrazine. Acuron Flexi received EPA registration on February 9, 2016. After 15 years, Syngenta spent about $300 million developing Acuron, and continues to invest nearly $4 million on global R&D every day to help deliver powerful solutions and help growers meet their greatest needs – year after year.

Couple Remains Committed to Golden Harvest After 30 Years

SyngentaAgronomy — Thu, 10 Nov 2016 21:01:42 +0000

Milton, WI: Jeff and Joan Shadel were counting down the days until they head to their winter home in Hawaii. With harvest in full swing, they knew those days would be plenty busy. To help them do their best, the Shadels rely on Golden Harvest® Corn. They’ve been doing so for about three decades, with solid results keeping them coming back year after year. “Golden Harvest Corn is a product that we have faith in,” he said. “It comes out of the ground well, has good seedling vigor, and in the end, it maximizes the value to our farm.” This season, the couple planted Golden Harvest hybrids G95D32-3110 and G98L17-3000GT brands, which Jeff Shadel predicted could hit 200 bu/A. Much to their delight, both hybrids performed even better. Golden Harvest hybrid G95D32-3110 brand came in at 243 bu/A and G98L17-3000GT brand yielded 220 bu/A on the Shadels’ farm. Jeff and Joan Shadel were gearing up to harvest their Golden Harvest hybrids when the Harvest Chasers visited their farm, which they said looked about as good as they ever have.

Wisconsin Farmer Chooses NK Soybeans Based on Performance, Price

SyngentaAgronomy — Fri, 11 Nov 2016 16:19:36 +0000

New Richmond, WI: Darren Dittman hasn’t always planted NK® Soybeans, but after watching how they performed for neighboring growers, it wasn’t a difficult decision to switch. “They were doing good in everyone else’s fields – and they were the best price,” Dittman said. For the first time in 2016, all of his soybean fields were NK. His change paid off. Their combination of best-in-class genetics and the latest traits have helped him yield well while withstanding pests and diseases like white mold, which threatened crops across his area. His current favorite is NK Soybeans S12-H2 brand, which features strong soybean cyst nematode (SCN) protection and solid Phytophthora root rot tolerance. SCN is a damaging pest that costs American soybean farmers 1.2 billion dollars annually, so it’s no wonder Dittman is intent on choosing varieties with built-in tolerance. “My NK Soybeans S12-H2 brand stood well this year, and just flew through the combine,” Dittman said. “I’m planning to plant all NK Soybeans again next year.” All photos are the property of Syngenta or used with permission.

Change Leads to Giant Ragweed Control

SyngentaAgronomy — Mon, 14 Nov 2016 15:13:53 +0000

Nebraska: Wet conditions around planting during the 2015 season made it difficult for Jeff Miller, a Clatonia, Nebraska-based grower, to make timely herbicide applications. Once he was able to apply, the giant ragweed control did not meet his expectations, leading to weed seed carryover and a field full of giant ragweed prior to planting in 2016. Looking for added application flexibility and improved control of giant ragweed in 2016, Jeff chose to apply Acuron® corn herbicide, a convenient premix with four active ingredients, three effective modes of action and a wide window of application – from 28 days pre-plant up to 12-inch corn. Here’s a visual recap of the field’s transformation after application: April 25, 2016: Clatonia, Nebraska: A mat of giant ragweed resulting from poor weed control with previous herbicides in 2015. June 2, 2016: The same field 37 days after a treatment of 2.7 qt/A of Acuron with 2, 4-D and Banvel® herbicides. June 16, 2016: A row in the field above 51 days after treatment.

Soybeans Yield Well in Arkansas Despite Drought Conditions

SyngentaAgronomy — Mon, 14 Nov 2016 16:02:28 +0000

McGehee, AR: For growers in southeast Arkansas, where hot, dry conditions are the norm, finding soybean varieties with the right genetics to withstand drought-prone weather can be a real game-maker. Layne Miles found his solution in NK® Soybeans. Particularly fond of NK Soybeans S47-K5 brand, Miles said he has seen the variety outperform and outyield the competition season after season. “I absolutely love my S47-K5s,” he said. “It has stood out each year we’ve had it.” Miles knew he had to try NK Soybeans on his own land after seeing his father hit up to 90 bu/A with them several years in a row. The average for the region is generally around 75-80 bu/A, and his whole field average this season was right on par. At some points, his monitor showed NK Soybeans S47-K5 brand yields reach as high as 100 bu/A in some locations. “The No. 1 important thing to me is yield,” Miles said. “That’s how a farm makes it.” All photos are the property of Syngenta or used with permission.

The Overlooked Connection between SDS and SCN

SyngentaAgronomy — Mon, 14 Nov 2016 16:11:10 +0000

Sudden death syndrome (SDS) showed up in multiple Midwestern states late this summer. Although the yellow, defoliating leaves can appear ‘suddenly,’ the fungus starts infecting the roots much earlier in the season. Cool and wet conditions typically favor SDS development, but weather isn’t not the only contributing factor. Soybean cyst nematode (SCN) causes extensive root damage, making plants more vulnerable to SDS infection, according to The Ohio State University Extension. With no mid-season treatment options available for either SDS or SCN, Syngenta advises growers to manage them together in 2017. A comprehensive preventive strategy includes planting resistant varieties and treating them for protection against both SDS and SCN. In addition to providing SCN resistance, SDS-resistant NK^® Soybean varieties offer the industry’s best SDS ratings when compared to competitors’ varieties. To enhance the performance of those varieties, Clariva^® Complete Beans seed treatment, a combination of separately registered products, offers season-long SCN protection and can help reduce the impact of both pathogens. The addition of Mertect^® 340-F fungicide applied with Clariva Complete Beans helps to further protect high-value seed with added SDS protection. Jason Bond, plant pathologist at Southern Illinois University, recommends treating resistant varieties to target both fungi and nematodes together because the two pests are attacking soybean roots at the same time. The seedling stage when roots are developing is a critical time to shield soybeans from such pests. Shawn Conley, professor at the University of Wisconsin-Madison, also discusses the importance of managing SDS and SCN together in this video. While weather is one factor that growers can’t control, making a proactive decision to protect soybeans from both SDS and SCN can help growers maximize their yield potential.

Missouri Farmer Reports Record Yields After Tough Season

SyngentaAgronomy — Mon, 14 Nov 2016 18:57:18 +0000

Bowling Green, MO: June was such a dry month that Clete Miller said it put his growing season on the brink of disaster. But with what he described as a “rock star” corn hybrid and “one of the best” soybean varieties on the market, he was able to not just hold on, but outperform expectations. His Golden Harvest® hybrid G16K01 brand yielded up to 190 bu/A in his fields, which he said was well above average in the area. In addition, NK® Soybeans S39-C4 brand hit a personal record of 85 bu/A in an area that typically averages around 40 bu/A. Solid genetics and the agronomic benefits they brought to these crops played a big role. “Even with the stress environment we had early on, Golden Harvest hybrid G16K01 brand carried right through until we got to later-season rainfall,” Miller said. “It emerged quickly, had early-season vigor and, once it came out of the ground, started growing and kept growing.” For his soybeans, built-in resistance to sudden death syndrome (SDS) helped greatly. The disease is a fixture in the region, but Miller said growers who tried NK Soybeans S39-C4 brand were able to stand up against it. “Almost all of my customers said NK Soybeans S39-C4 brand was one of the best beans they’ve ever had, and it was the same thing on our farm,” said Miller, who is also a Golden Harvest Seed Advisor™. “If you’re looking for yield, standability, tolerance to SDS and other diseases – this is good, or better, than anything on the market.” All photos are the property of Syngenta or are used with permission.

On-Farm Trials Reaffirm Seed Selection Decision at Harvest

SyngentaAgronomy — Tue, 15 Nov 2016 14:00:31 +0000

Rice, MN: When it comes to growing the best corn and soybeans, seeing is believing for Denny Popp. That’s why each year he conducts his own hybrid and variety comparison trials. The trials pit a range of corn and soybean seed brands against each other to compare factors such as yield, standability and emergence. It’s this approach that led him to try Syngenta seed brands, and it hasn’t let him down. “I first started growing NK® Soybeans 6 years ago. The varieties drew my attention in my plot results, and then I decided to try Golden Harvest® Corn, too,” Popp said. “The Golden Harvest Corn is awesome and the NK Soybeans are the best in the business. Other brands can’t compare.” Among the 12 hybrids in his 2016 corn strip, 9 of the top 10 performers were Golden Harvest. Among his 22 tested soybeans, “NK took all of the first 10 spots, and both Asgrow® and Pioneer® varieties were also in the trial.” Golden Harvest hybrid G95D32 brand was one of Popp’s top performers, with a peak yield of 287 bu/A. On the soybean side, NK Soybeans S14-A6 brand stole the show, yielding 73.8 bu/A. All of Popp’s NK Soybean varieties were protected by CruiserMaxx® Beans with Vibrance® fungicide/insecticide seed treatment, a combination of separately registered products, which offers best-in-class insect protection and delivers systemic root protection against certain seedborne, soilborne and foliar diseases. Denny Popp's NK Soybean varieties took home the best of the bean honors in his plot trials this season. All photos are the property of Syngenta or are used with permission.

Part 1: Multiple Modes of Action Control Tough Weeds

SyngentaAgronomy — Tue, 15 Nov 2016 14:42:33 +0000

Kansas and Nebraska: Tough, early-season weeds are the greatest threat to high-yielding corn. In a survey* of top corn growers, the top five weeds they identified as being difficult to control were waterhemp, marestail, Palmer amaranth, giant ragweed and morningglory. As these weeds, and others, have developed resistance, many current herbicide programs have lost their effectiveness – costing growers both time and money. Starting in June and concluding in August, growers in 10 of the top 11 corn-producing states who used Acuron® or Acuron Flexi corn herbicides, premixes with multiple effective modes of action and active ingredients, shared their results with each herbicide against the toughest weeds. Using a robust pre-emerge herbicide with multiple, effective modes of action to stop weeds before they emerge results in better control, prevents additional weed seed production, and helps manage herbicide resistance. Here’s a recap of growers’ experiences in Kansas and Nebraska: June 13, 2016: Girard, Kansas: Prior to using Acuron, grower Steve Murphy’s toughest weeds were cocklebur and velvetleaf. His pre-emerge application of Acuron at 2.5 qt/A made on March 24, 2016, showed good residual on both weeds 81 days after treatment. June 14, 2016: Sterling, Kansas: Grower Andy Zwick had populations of glyphosate-resistant marestail in his fields prior to treatment. Acuron applied in two passes, 1.25 qt/A pre-emerge with glyphosate on May 10, 2016, followed by Acuron at 1.25 qt/A when the corn was 12 inches tall. June 15, 2016: Dorchester, Nebraska: Grower Jayme Dick-Burkey’s field also had a history of glyphosate-resistant marestail. Acuron applied pre-emerge at the full labeled rate with glyphosate. June 16, 2016: Clatonia, Nebraska: Grower Jeff Miller’s field was covered in a mat of giant ragweed prior to planting. Acuron applied pre-emerge at 2.5 qt/A with 2, 4-D and Banvel® herbicides on April 10, 2016. Photo taken 51 days after treatment. See the before and after photos here. June 16, 2016: Lindsay, Nebraska: Grower Ken Kurtenbach applied Acuron pre-emerge at the full labeled rate on May 10, 2016. Photo shows control of giant ragweed 37 days after treatment. June 16, 2016: Lindsay, Nebraska: A planter skip in grower Glenn Beller’s field shows complete control of waterhemp. Acuron applied pre-emerge at the full labeled rate with Touchdown Total® on May 5, 2016. Photo taken 42 days after treatment.

Part 2: Multiple Modes of Action Control Tough Weeds

SyngentaAgronomy — Wed, 16 Nov 2016 14:00:48 +0000

As mentioned in the previous post, growers in top corn-producing states evaluated the performance of Acuron® and Acuron Flexi corn herbicides in their fields for this series of reports. In late June, growers in Wisconsin and Northern Illinois shared their results. Giant ragweed was the most problematic weed in the fields there, although weeds like lambsquarters and marestail were also concerns. While most growers in this area used Acuron, others applied Acuron Flexi to their fields. Tony Bomkamp, a grower from Muscoda, Wisconsin, who used both herbicides on his farm, shared that like Acuron, Acuron Flexi kept the tough weeds out with a single pre-emerge application. Although pre-emerge is the preferred timing for both Acuron and Acuron Flexi, conditions forced some growers to make post-emergence applications. Acuron has a wide application window, from 28 days pre-plant up to 12-inch corn, and Acuron Flexi can be applied 28 days pre-plant up to 30-inch corn. Here’s a recap: June 21, 2016: Baraboo, Wisconsin: Grower Tim Johnson had difficulty controlling giant ragweed and lambsquarters in previous seasons. Photo shows a pre-emerge application of Acuron at 3 qt/A in his field 42 days after treatment. June 22, 2016 Muscoda, Wisconsin: Grower Tony Bomkamp applied Acuron and Acuron Flexi in different fields on his farm. Both fields had a history of giant ragweed and lambsquarters pressure prior to treatment. (Left) Acuron applied immediately after planting at 3 qt/A on April 28, 2016. Photo taken 55 days after treatment. (Right) Acuron Flexi applied immediately after planting at 2.25 qt/A on April 22, 2016. Photo taken 61 days after treatment. June 22, 2016: DeSoto, Wisconsin: Joel and Rhiannon Kunert, a husband-and-wife team, also had fields with giant ragweed prior to treatment. Acuron applied post-emerge at 2.5 qt/A on May 20, 2016. Photo taken 33 days after treatment. June 23, 2016: Geneseo, Illinois: Acuron applied post-emerge at 2.75 qt/A with Touchdown Total® 14 fl oz and .5 lb atrazine shows control of giant ragweed and marestail in grower Rob DeFauw’s field 37 days after treatment.

Diversity is Key for Clean Soybean Fields

SyngentaAgronomy — Tue, 15 Nov 2016 15:35:42 +0000

More than 50 percent of the 82 to 83 million soybean acres in the U.S. have been infested with glyphosate-resistant weeds. Some of these weeds are also resistant to other herbicides, such as PPO- and ALS-inhibitors. Keeping fields clean throughout the season takes a little foresight and organization. To help with planning, consider the following:

The weed spectrum likely varies in each field. Know which weeds to target in order to apply herbicides that will be effective on those specific weeds.
A diverse and broad-spectrum weed management program can begin with a burndown application where dense weed populations or scattered, hard-to-control weeds exist.
For continued control, an effective pre-emergence herbicide will help reduce early-season weed competition.
Overlapping residuals help keep fields free of weeds longer while improving yields and resistance management practices. With unpredictable weather, a post-emergence herbicide with effective multiple modes of action offers growers a safety net for the difficult-to-control weeds.

In addition to a comprehensive portfolio of soybean herbicides to help you fight weed resistance in your field, Syngenta offers the Resistance Fighter^®program to help provide expertise and local weed management recommendations to growers and retailers.

Part 3: Multiple Modes of Action Control Tough Weeds

SyngentaAgronomy — Thu, 17 Nov 2016 14:00:11 +0000

Following results from Kansas and Nebraska, and Wisconsin and Northern Illinois, growers in Southern Illinois and Missouri share their evaluations of Acuron® and Acuron Flexi corn herbicides. In these areas, waterhemp was the biggest concern. Growers in Southern Illinois also named morningglory, pigweed and marestail as problematic weeds. Here’s a recap: June 27, 2016: New Florence, Missouri: Kent Hall’s field had a history of waterhemp pressure prior to treatment. Acuron applied at 1.5 qt/A for burndown in early April followed by 1.5 qt/A of Acuron in early June. June 28, 2016: Tamms, Illinois: Pigweeds were a problem in grower Joshua Miller’s field prior to treatment. Acuron applied at 3 qt/A with nitrogen in early April. June 28, 2016: Anna, Illinois: Prior to treatment, grower and retailer Brad Dodd had concerns about populations of marestail, morningglory and waterhemp in this field. Acuron applied at 3 qt/A in early April. Check the Know More, Grow More Digest to read about results in Ohio and Iowa. Explore our performance map to see how Acuron defeats tough weeds in your area.

Sample Now for Soybean Cyst Nematode

SyngentaAgronomy — Fri, 18 Nov 2016 14:00:43 +0000

Harvest is nearing completion, and fields are settling into the sweet spot for soil sampling. Extension services and agronomists recommend growers sample soil for soybean cyst nematode (SCN) this fall, after harvest but before a hard freeze or significant snowfall occurs. SCN presence has been expanding across the U.S. every year, yet many growers are still unaware of SCN presence on their farm. Not only will sampling in the fall provide timely results in preparation for next season, but it will deliver a more comprehensive image of SCN populations. Because SCN has multiple generations throughout one season, testing mid-season will not provide a complete picture of the severity of a grower’s SCN problem. While SCN-resistant soybean varieties have been a common tool for control, decreasing efficacy of the most common source of genetic resistance, PI88788, makes it critical to incorporate a broader management program. In addition to planting resistant varieties, growers are encouraged to practice crop rotation and plant varieties treated with a seed-applied nematicide. Once SCN is present, it cannot ever be entirely eliminated. To properly manage SCN, growers must use all the tools available. To help explain the severe threat SCN poses, Syngenta teamed up with university experts across the Midwest to create a series of videos. Available on ClarivaCompleteBeans.com, these videos explore the challenges and provide in-depth management recommendations. If soil samples test positive for SCN, it’s not too late. In addition to planting an SCN-resistant variety and practicing crop rotation, many universities now recommend incorporating a seed-applied nematicide like Clariva^® Complete Beans seed treatment, a combination of separately registered products, to help manage SCN populations – including those becoming resistant to SCN-resistant genetics. Clariva Complete Beans delivers lethal, season-long protection against SCN and enhances the performance of SCN-resistant varieties.

Bears Notwithstanding, Golden Harvest Hybrids Excel

SyngentaAgronomy — Wed, 16 Nov 2016 22:18:19 +0000

New Richmond, WI: Farmers often deal with troublesome critters in their cornfields: gophers, raccoons, deer and the like. Scott Johnston faces a bigger challenge – bears! “Sometimes when I’m combining off the road a ways, I’ll get into a patch where there’s an acre of downed corn. All the stalks are smashed down like you’d think a tornado went by,” Johnston said. “But it’s really bears. They lie there several days, eating stalk after stalk.” Wisconsin has a thriving black bear population estimated at more than 28,000 bears. According to the Wisconsin Department of Natural Resources, the black bear’s primary range is located in the far northern third of the state, but an abundant population and suitable bear habitat has facilitated the southerly movement of bears. That means Johnston is probably not the only Wisconsin grower battling black bears in their fields. Although the reasons are undoubtedly different, the bears appear to appreciate Golden Harvest® Corn hybrid G95D32 brand as much as Johnston does. “None of my corn acres have gone down against any winds. In fact, the Golden Harvest Corn stalks seem thicker than any other around,” Johnston said. “They stood straight through harvest, except when the bears got to them!” A grower for nearly three decades, this was Johnston’s fifth year planting Golden Harvest hybrids, and he plans on growing them again next year. “What really matters most to me is the germination rate,” he said. “I pay pretty close attention to ease of germination, and I feel the Golden Harvest Corn germination is really good. My yields are as good as or better than my neighbors.” This year, Johnston yielded a field average of 206 bu/A across his corn acres, all of which were planted with Golden Harvest. Along with germination, stalk and yield satisfaction, Johnston said he continues to grow Golden Harvest because of the customer service behind the hybrids. “My Golden Harvest Seed Advisor™ Doug Croes does a good job,” he said. “He’s easy to work with, and I respect how his family maximizes yield on their own acres.” All photos are the property of Syngenta or are used with permission.

Corn Hybrid Shows Resilience Throughout an Unpredictable Season

SyngentaAgronomy — Thu, 17 Nov 2016 15:11:40 +0000

Edgerton, MN: Corey Johnson and his NK® Corn have something in common: they both go the extra mile. While Johnson lives with his wife and four young children near Wisconsin, he regularly drives three hours west to farm with his dad, Dennis, near South Dakota. “I worked in the corporate world for seven years, but then I had the opportunity to come back to the family farm. I like being outside and seeing something you put in the ground grow,” Johnson said. “Farming gives you freedom. The challenges and decisions you make every day – it makes life interesting.” Part of Johnson’s formula for success is growing NK Corn hybrid N45P brand, an Agrisure Artesian® hybrid. He and his dad saw great results with the hybrid over the past two years, excelling even when the weather hasn’t fully cooperated. “About 40% of our seed was planted when we had to hold off for two weeks because it was so cold and wet. Still, the seed emerged evenly,” Johnson said. “It was impressive.” As an Artesian™ hybrid, N45P brand provides an extra form of insurance with its ability to maximize yield when it rains and increase yield when it doesn’t. “We had a hot spell in July, and the ears were still hanging on tough at harvest,” Johnson said, adding that they also withstood blustery conditions. “We had winds up to 30 mph, but we still had good-standing corn and no green snap. We’re grateful for that.” Johnson plans to plant NK Corn on 100% of his corn acres again next year and recommends the brand to other growers. “Give it a try and see. There’s plenty of NK Corn offerings for every farm. No matter your soil type and whether you have continuous corn or corn-on-soybean acres, you can find a corn hybrid that’s right for you,” he said.

Innovation, Half Century of Experience Combine for Successful Harvest

SyngentaAgronomy — Thu, 17 Nov 2016 15:18:35 +0000

Raymond, SD: Paul Waldner may have been farming for more than a half century, but his input decisions are still guided by the same principle: using the best products and using them early. It’s what led him to first try NK® Corn in 1957, and it’s what has kept him planting it every year since. “The yields are always there, and the service is good, too,” he said. 2016 reaffirmed his commitment to the brand. Despite a severe lack of rain in the latter half of the season, his NK Corn hybrids N49W, N50D and N42Z brands all produced good yields, together averaging 180-190 bu/A. In some spots, NK hybrid N50D brand yielded as high as 250 bu/A, he added. This year, Weldner tried two of the latest crop protection offerings from Syngenta: Acuron® herbicide, which features three modes of action to control the toughest weeds, and Trivapro® fungicide, which delivers long-lasting disease control and crop enhancement benefits. Yet again, his guiding principle didn’t let him down. “They worked well for us, and we’ll continue to use them,” he said. “Why would we change a good thing?” Paul Waldner has harvested NK Corn on his South Dakota farm for nearly 60 years.

Part 4: Multiple Modes of Action Control Tough Weeds

SyngentaAgronomy — Fri, 18 Nov 2016 14:03:04 +0000

In this edition, growers in Iowa and Minnesota share their experiences with Acuron® and Acuron Flexi corn herbicides in 2016. Iowa growers singled out waterhemp as their toughest weed to control, while Minnesota growers cited both waterhemp and giant ragweed. Extremely wet conditions in Minnesota in August made in-field photography impossible, but growers there were happy with the performance of both Acuron and Acuron Flexi. Mike Anders, a grower and retailer from Nerstrand, Minnesota, said the tank mix flexibility and geographic flexibility in Acuron Flexi are especially beneficial to him since the product does not contain atrazine. Here’s a recap: July 27, 2016: Reinbeck, Iowa: Matt Shoup’s field had a history of waterhemp pressure prior to treatment with Acuron. Acuron applied pre-emerge at 3 qt/A with nitrogen on April 18, 2016. Photo taken 100 days after treatment. June 27, 2016: Reinbeck, Iowa: Another field with a history of waterhemp pressure prior to treatment with Acuron. Acuron applied pre-emerge at 3 qt/A with 24 fl oz glyphosate and .5 lb atrazine on May 18, 2016. Photo taken 70 days after treatment. June 27, 2016: Traer, Iowa: Two views of the same row in a field that had waterhemp pressure prior to treatment with Acuron. Acuron applied pre-emerge at 3 qt/A on April 20, 2016. Photo taken 98 days after treatment. August 24, 2016: Hayward, Minnesota: Wet conditions prevented in-field photos, but grower and retailer Tim Westrum reported that Acuron performed well against his two toughest weeds: giant ragweed and waterhemp. A foundation rate of Acuron was applied pre-emerge and followed at a later date with an application of Halex® GT.

Part 5: Multiple Modes of Action Control Tough Weeds

SyngentaAgronomy — Mon, 21 Nov 2016 14:00:05 +0000

In this edition, growers in Ohio, Indiana and Michigan share their results controlling tough weeds with Acuron® corn herbicide in 2016. This is the final post in a series on Acuron and Acuron Flexi, which also covered:

Here’s a recap of growers’ experiences in the eastern Corn Belt: July 25, 2016: Urbana, Ohio: Paul McGuire’s field had a history of giant ragweed and pigweed pressure prior to treatment. Acuron applied pre-emerge at 2.5 qt/A with 1 qt/A atrazine on April 28, 2016. Photo taken 88 days after treatment. Although the field did not have Palmer amaranth, Paul reported that its presence in the area contributed to his decision to use Acuron. August 31, 2016: Albion, Indiana: Due to manure applications, Al Osterlund’s field had heavy populations of marestail, giant ragweed and pigweed prior to planting. Acuron applied post-emerge at 2.5 qt/A on April 20, 2016. Photo taken 133 days after treatment. August 31, 2016: Sturgis, Michigan: Chris Pueschel’s field had a history of Pennsylvania smartweed and yellow nutsedge pressure prior to treatment. Acuron applied post-emerge at 2.5 qt/A on April 20, 2016. Photo taken 133 days after treatment. Explore our performance map to see how Acuron defeats tough weeds in your area.

NK Brings High Yields in the Face of Drought

SyngentaAgronomy — Fri, 18 Nov 2016 19:08:12 +0000

Coleman, GA: There aren’t many farmers in Joe Shivers’ part of the country that haven’t been affected by the ongoing drought. Shivers certainly hasn’t been immune, either – especially since his soybean acres aren’t irrigated. Even so, his NK® Corn and Soybeans still performed better than others. “NK Corn hybrids N83D-3000GT and N78S-3111 brands were the best corn I had. They yielded approximately 265 bu/A, while my DeKalb® hybrids fell in the 220 to 230 bu/A range. My NK Soybeans yielded more than 15 bu/A better than competitors, on average, as well,” Shivers said. This is his second year growing NK Corn and his first with NK Soybeans. He first became interested in the NK product line because his local rep had such success with the hybrids and varieties. The previous season’s yields were also a deciding factor. “I always look at yield reports from the year before,” Shivers said. Based on that, “I’ll be planting more NK Corn and NK Soybeans.” All photos are the property of Syngenta or used with permission. Syngenta hereby disclaims liability for third party websites.

Trust in NK Runs in the Family

SyngentaAgronomy — Mon, 21 Nov 2016 19:25:06 +0000

Hayfield, MN: Tom and Mike Franke not only have a lifetime of experience farming, but a lifetime of experience farming together. The two brothers can still be found together on the family farm today, helping one another out and working as a team. Almost as strong as their loyalty to each other is their loyalty to NK® Soybeans. They’ve been planting the brand for more than 10 years and don’t intend to stop anytime soon. “Overall, NK Soybeans just have a complete package,” Tom Franke said. “You have to try other seed once in a while to see if there’s anything better out there, but we’ve just found over the years that NK has had the best varieties for our soil.” This season rewarded their loyalty yet again. Even in the face of unusually wet conditions, NK Soybeans S20-T6 brand, a high-performing variety with strong resistance to sudden death syndrome, delivered an average 73 bu/A. From right, Ian Franke has joined dad Mike and uncle Tom to support the family operation. All photos are the property of Syngenta or used with permission.

New Management Plan Reins in Weed Escapes

SyngentaAgronomy — Tue, 22 Nov 2016 14:00:20 +0000

Hamlin County, SD: Considering that early-season weeds rob yield and late-season weeds deposit thousands – even millions – of seeds into the weed seed bank to produce future threats, it’s no surprise that weed pressure is one of the top concerns for growers each season. The accumulation of so many seeds creates a challenge that is both expensive and difficult to manage in future seasons. On Jeremy Noem’s farm, waterhemp, kochia and marestail are the biggest threats to his NK® Corn hybrids, but through proactive management, he’s been able to keep them under control. When his previous herbicide program started having escapes, he took action to regain the upper hand. “Last year, we had spots where we had escapes,” Noem said. “This year, we applied Acuron® herbicide in one pass at 2.5 qt/A with glyphosate, and it worked well. We didn’t have weeds come up.” Acuron is a premix of four active ingredients and three effective modes of action that can be applied from 28 days pre-plant up to 12-inch tall corn. The cleaner fields helped Noem’s NK Corn hybrids N33W and N49W brands thrive, delivering an average 180-200 bu/A. “The yields are better this year and that’s always the goal,” he said. Introducing Acuron herbicide into his weed control program enabled, Jeremy Noem to bring his number of observed weed escapes this season down to zero.

Agronomics and Weed Control Deliver Positive Results

SyngentaAgronomy — Wed, 23 Nov 2016 14:30:20 +0000

Sacred Heart, MN: A soggy fall could have dampened Jeff Agre’s harvest expectations, but his Golden Harvest® Corn hybrids’ performance up to that point gave him plenty of hope. “I was impressed with the stalk strength, ear retention and overall plant health,” said Agre, who grew Golden Harvest hybrids G03A50 and G06N80 brands. “The drydown was also pretty good even with the late season rainfall.” The end result: yields that still averaged as high as 260 bu/A. Agre was able to keep high-threat weeds like waterhemp in check which certainly helped come harvest. He applied a full-rate, two-pass post-emergence application of Acuron® Flexi herbicide, which combines three active ingredients and two complementary modes of action to deliver a multi-targeted approach to weed control. “We didn’t see any waterhemp issues in the fields at all this fall,” Agre said. “On a scale of one to five, I would give Acuron Flexi five stars.” Genetics allowed Agre’s Golden Harvest hybrids to thrive despite a wet final stretch of the growing season.

Retailer Relationship Makes Big Impact at Harvest

SyngentaAgronomy — Wed, 23 Nov 2016 15:30:59 +0000

De Smet, SD: When it comes to choosing his hybrids and varieties, Greg Albrecht’s relationship with his retailer, Win Noem, is critical. He often relies on Noem to advise him before making his seed and herbicide decisions. “I’ve been planting NK® Corn and Soybeans for almost 20 years now, and I work mostly with Win,” Albrecht said. “And to tell you the truth, he handles the reins on our whole corn and soybean program. We have so much going on between crops and livestock that it’s good to work with him and have his expertise.” This trust has paid off. Noem’s suggestion to use CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products, on his soybeans made a difference in terms of controlling aphid pressure. “We’ve noticed that when we use it, we don’t have to spray for aphids nearly as early – or sometimes at all,” Albrecht said. “We had some dry spells this year, but even so, they still performed well,” he said. “My soybeans are yielding 10% to 20% higher than last year – across the board.” Greg Albrecht (left) relies on retailer Win Noem’s (right) expertise to help make his seed and crop protection decisions.

Switch in Brand Loyalty Pays Off in Yield

SyngentaAgronomy — Fri, 25 Nov 2016 15:00:44 +0000

New Richmond, WI: After graduating from the University of Wisconsin-River Falls a decade ago, Justin Gillis returned home to his Pioneer®-loyal family farm. It didn’t take long, though, for price and competitive performance to make Gillis consider something new. He introduced his family to NK® Soybeans seven years ago, and today, is as committed to NK as they come. “The stand of my NK Soybeans stays good – better than Pioneer. The Pioneer varieties were tougher to get through the combine,” Gillis said. The addition of Syngenta products like CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products, has only improved his opinion. “It seems soybeans either get off to a strong start or struggle from the beginning. My NK Soybeans came up really nice this year, probably because of the CruiserMaxx Beans with Vibrance seed treatment I used,” Gillis said. With the insecticide/fungicide seed treatment shielding his soybeans’ genetic potential, Gillis was able to get the most out of his acres while others struggled. “It was hard to reach 60 bu/A because it’s been wet – really wet – around here this season. But NK Soybeans S10-P9 brand did,” he said. NK Soybean S10-P9 brand is known for its great standability, solid stress tolerance and exceptional yields.

Top-of-the-Line Performance, Even After Dry Season

SyngentaAgronomy — Sat, 26 Nov 2016 15:00:06 +0000

Pandora, OH: Chuck Niese can get a bit competitive when it comes to his soybeans. He wants to know he’s growing the best crop in town, which is why he conducts regular field trials to see how he stacks up against the competition. And each year, the performance of his NK® Soybeans reassure him. “They are top of the line,” Niese said. “The Pioneer® varieties aren’t much competition, and though the Asgrow® soybeans are competitive, I don’t think they’ve ever won one of my plots.” Niese was especially impressed with the performance of his NK Soybeans this year, considering the lack of rain he received. His farm got off to a good start during planting and had a nice 3-inch rain in early June, but it virtually ended there. Until September, he didn’t get even 1/10 of an inch to shake out of his rain gauge. Even now, he said it’s still dry. “It was just dry, dry, dry this season,” said Niese, who is also a Golden Harvest® Seed Advisor™. Even so, his NK Soybeans S35-C3, S34-N3 and S56-M8 brands outlasted the drought with their advanced genetics. Together they averaged 60 bu/A – plenty to keep him hopeful about who will win next year’s field trials. “I like to plant fuller-season varieties because I feel I can get more yield out of them,” explained Niese. “I’m very happy with NK Soybeans. They’re second to none.” All photos are the property of Syngenta or are used with permission.

Where Others Failed, Golden Harvest Hybrid Shines

SyngentaAgronomy — Mon, 28 Nov 2016 21:16:08 +0000

Bogard, MO: Going into the season, Kyle Hawkins didn’t expect much out of the thinner soils on his farm. But with Golden Harvest® hybrid G11U58 brand, he experienced above average results. “With competitors, you might see some falloff from the good dirt to the bad dirt. It would shine on good dirt, then it would hit a weaker spot and just kill you. Golden Harvest, though, has better consistency,” Hawkins said. In addition to its drought tolerance and ear flex benefits, Golden Harvest hybrid G11U58 brand’s strong standability was key to its success – helping the hybrid withstand 65-mile-per-hour winds early in the season. Ultimately yielding above 200 bu/A an average, Hawkins said his investment in Golden Harvest Corn has been more than worthwhile. “I’m a believer,” he said.

First-time Golden Harvest Grower Ranks Hybrid Among ‘Best Ever’

SyngentaAgronomy — Tue, 29 Nov 2016 20:00:41 +0000

Buda, IL: For Doug Newman, owner-operator of Legacy Oaks Farms, farming has been a family profession for three generations. It’s a way of life that offers a level of independence that can’t be found anywhere else. As part of Newman’s independent streak, he is always trying new brands of hybrids. This year, he chose to plant Golden Harvest® Corn for the first time, a decision that has paid dividends. “We had some wind events come through in June and July, and we had some hybrids that went down. I’m happy to say that Golden Harvest wasn’t one of them,” Newman said. “As we start to harvest, all of the Golden Harvest hybrids have stood well and stalk quality looks good.” Golden Harvest hybrid G14R38 brand performed particularly well. “That hybrid was right there with the best we’ve ever seen,” Newman said. “We’re certainly happy with that.” Golden Harvest hybrid G107F23-3111 brand impressed him, too. It includes the Agrisure Viptera® trait, which offers the most comprehensive corn insect control for more, high-quality grain. “I couldn’t find any problems with that plant through the entire growing stage,” Newman said. “I would certainly be interested in planting more of that in the future.” As he evaluates hybrids for next season, Newman said it’s most important to him to consider:

How efficiently the hybrid used nitrogen and other nutrients
The yield it produced
Whether the hybrid needed extra inputs to perform well

After his first year planting Golden Harvest hybrids, Newman feels confident they will serve him well in the future. Grower Doug Newman (left) takes a break from harvest to speak to Kurt Varland, Seed Advisor Manager at Syngenta. Newman was a first-time Golden Harvest Corn grower in 2016 and plans to return for more in 2017. All photos are either the property of Syngenta or are used with permission.

Golden Harvest Delivers ‘Best Grain Crop We’ve Ever Had’

SyngentaAgronomy — Wed, 30 Nov 2016 14:00:52 +0000

Raymond, MN: It’s safe to say former Minnesota Corn Growers Association president Noah Hultgren knows a thing or two about corn. The fourth-generation farmer knows a good hybrid when he sees one – it’s what led him to Golden Harvest® Corn three years ago and has kept him coming back. With an 8,000-cow operation located just a few miles away from his farm, most of Hultgren’s corn is used for silage. “We’re paid on tonnage, and getting 25 tons is similar to 200 bu/A,” he said. “This year’s Golden Harvest Corn is the best grain crop we’ve ever had – we’ve never yielded more than 200 bu/A before, but we did this year.” Hultgren’s favorite for 2016 was Golden Harvest hybrid G01P52-3011A brand. An Agrisure Artesian® hybrid, G01P52-3011A brand converts water to grain more effectively than other hybrids. From emergence to harvest, he’s been impressed with his Golden Harvest hybrids’ standability. As a grower who sells his crop for tonnage, he it’s important for his corn to continue standing strong through November. “Overall, I’ve had a positive experience with Golden Harvest, so I’d say it’s worth giving it a shot,” Hultgren said. “They have a good variety of hybrids.” All photos are either the property of Syngenta or are used with permission.

Performance, Support Sell Grower on Golden Harvest Hybrids

SyngentaAgronomy — Thu, 01 Dec 2016 14:00:50 +0000

Annawan, IL: When it comes to choosing a seed brand, grower Rob DeFauw has found customer support to be as important as technology. That’s why he continues to choose Golden Harvest® Corn year in and year out. “If I have a question or concern, I can call, text or email, and the support team usually gets back to me within the hour,” DeFauw said. “They are there all year, and also help me walk fields, letting me know if they see a problem.” In addition to farming with his father-in-law, Rob DeFauw stays active as the Henry County (IL) Farm Bureau Director. Of course, it doesn’t hurt when the product performs as well as DeFauw’s Golden Harvest hybrids have, even in an up-and-down year like 2016. “We got in the fields 1 to 2 weeks earlier than last year, but we also had some gullywasher rains,” DeFauw said. “We were very impressed with the stalk quality. We haven’t had any ear rot or white mold disease issues, either.” Golden Harvest hybrid G07F23-3111 brand is a favorite of DeFauw’s. Because of its good drydown, DeFauw said he feels confident taking the 107-day hybrid straight from the field to his local ethanol plant without concern about getting docked for high moisture at the elevator. And because it’s equipped with the Agrisure Viptera® trait, he also had protection against above-ground insect pressure. “When we started using minimum- and strip-tillage practices, we also started using Agrisure Viptera so we wouldn’t worry about black cutworms or corn earworm,” DeFauw said. He further helped his corn reach its potential by applying Acuron® corn herbicide, which has four active ingredients and three modes of action for multi-targeted control of the toughest broadleaf weeds. “We were looking for something different this year, so we went with Acuron,” DeFauw said. “We want to keep our fields clean and stay ahead of (resistance) – and we were super happy with the herbicide.” All photos are the property of Syngenta or used with permission.

Grower Finds Great Yields and Value with NK Soybeans

SyngentaAgronomy — Tue, 29 Nov 2016 22:34:19 +0000

Janesville, MN: Yield may be a key driver for most seed, seed treatment and crop protection purchasing decisions, but Sean Mulcahey also measures products by another standard - value. In pursuit of a good-value soybean variety, Mulcahey found NK® Soybeans S20-T6 brand. “They’re lower cost than the competitors that I’ve found,” he said. “And they combine nicely.” Both qualities produce true value for Mulcahey, who also benefits from the variety’s industry-leading Sclerotinia white mold resistance, iron deficiency chlorosis tolerance and strong sudden death syndrome resistance. While the cost of this seed is lower than competitors, Mulcahey also says it yields as well or better than them. That’s why he has planted this variety in the past and plans to continue in the future. “NK Soybeans S20-T6 brand has been a nice, consistent high yielder. It yielded about 65-70 bu/A for me,” he said. “I’m probably going to plant all NK Soybeans next year.” Both yield and value are critically important to Sean Mulcahey, and he finds both in NK Soybeans S20-T6 brand.

Seeds Stand Up to Challenging Kansas Season

SyngentaAgronomy — Wed, 30 Nov 2016 14:49:05 +0000

Hepler, KS: This was hardly a textbook growing season for Wyatt Harris. May was cool and was followed by a dry June. Strong storms then threatened crop standability, and to top it all off, he faced late-season disease pressure including southern rust. 2016 put both his patience and his Golden Harvest® Corn and NK® Soybeans to the test, but fortunately, everything proved to be resilient. “This was probably the second best corn crop we ever raised,” Harris said. “It emerged wonderfully, and it handled the cooler weather well.” For Harris, this highlighted the benefit of planting hybrids and varieties best-suited for his acres. As a Golden Harvest Seed Advisor™, it’s something he places a particular focus on. Golden Harvest hybrids G07B39-3111A and G11U58-3220 brands were top performers, yielding up to 185 bu/A on average in some areas. This was approximately 10 bu/A higher than competitor products in the area, he said. On the soybean side, NK Soybeans S46-L2 brand yielded almost twice as much as other soybeans in the area, hitting 65 bu/A. “I believe they’re the best beans in the market,” Harris said, noting the many 4-bean pods he saw on his varieties this year. “The portfolio just works for us – if it didn’t, I wouldn’t be a dealer.” All photos are the property of Syngenta or used with permission.

Strong Yields and Premiums Help Improve ROI

SyngentaAgronomy — Thu, 01 Dec 2016 20:21:08 +0000

Pocahontas, IA: Like growers in many areas this season, Ryan Peterson faced the ever-present threat of yield loss from excessively wet conditions at planting and just before harvest. And yet, Peterson said his corn escaped the worst. Enogen® hybrid E106N8-3000GT brand proved to be a standout hybrid in his fields. It not only overcame the late-season leaf diseases that struck his area after the heavy rains, including anthracnose and Goss’s Wilt, but also dried down well. The result: 237 bu/A, which were 10-15 bu/A above the regional average. “Enogen has absolutely improved my ROI,” said Peterson, who is also a longtime Golden Harvest® Seed Advisor™. An in-seed innovation available exclusively from Syngenta, Enogen corn features the first biotech corn output trait designed to enhance ethanol production. By offering alpha amylase enzyme directly in the grain, Enogen hybrids eliminate the need for ethanol plants to source liquid amylase. Growers are eligible to earn up to a 40-cents-per-bushel premium for Enogen grain delivered to participating ethanol plants. "Our Enogen yields have been some of our highest since we started growing the product. When we take that plus the premium – in some cases, it’s doubled our return per acre,” Peterson said.

Trivapro Proves Beneficial With or Without Disease Pressure

SyngentaAgronomy — Fri, 02 Dec 2016 14:00:42 +0000

Albert Lea, MN: Richard Stadheim represents the 4th generation of a family steeped in farming. Needless to say, he has a wealth of experience that helps him appreciate when something simply works. This year, he really appreciated Trivapro® fungicide. “Disease pressure [in the area] wasn’t as evident this year as in the past, but where we used Trivapro fungicide on the corn, we definitely saw a positive result,” Stadheim said. With three active ingredients, Trivapro delivers long-lasting disease control and crop enhancement benefits like stronger stalks, healthier roots and bigger ears that maximize yield potential. Compared to those treated with other fungicides, Stadheim said his Golden Harvest® Corn protected by Trivapro not only looked better, it also yielded as much as 15 bu/A more than untreated areas of his farm. “I like that Trivapro has a longer activation window and a longer residual,” he said. “That was why I thought, well, if this has a longer time that it can work, then it can be yield positive.” With the results he saw, experience says Trivapro will be back on the farm in 2017. The Harvest Chasers caught up with grower Richard Stadheim on his Minnesota farm to learn how Trivapro fungicide performed this season.

Local Expertise Drives Local Success

SyngentaAgronomy — Fri, 02 Dec 2016 15:16:11 +0000

Byron Center, MI: For Golden Harvest® Seed Advisor™ Dan Heasley, relationships are everything. They were at the core of his grandfather’s seeds business, and they’re critical to how he and his father run their own business today – asking questions and learning about their customers’ lives, fields and preferences. It’s through these relationships and knowledge of local agronomic conditions that Heasley is able to help his customers make the best decisions for each of their fields. For example, knowing that the area has significant sudden death syndrome (SDS) pressure, Heasley regularly recommends a soybean variety that can stand up to it: NK® Soybeans S20-T6 brand. “We’re seeing fields with an average of 60 to 70 bu/A – and our area usually averages around the mid-40s,” Heasley said. “One of the reasons that we recommend S20-T6 brand soybeans to our growers is because of their strong disease package. They can be planted pretty much everywhere and they’re not going to fail you.” In addition to picking varieties with solid genetics, he suggests protecting investments with a seed treatment like Clariva® Complete Beans, a combination of separately registered products. Clariva Complete Beans provides superior protection against damaging insects and diseases during the critical early-growth stage, making a noticeable difference come harvest. “The guys that are using Clariva Complete Beans on their soybeans, they’re the ones that are getting the best yields,” Heasley said. “These are some of the best bean yields I’ve ever seen.” Golden Harvest Seed Advisor Dan Heasley recommends NK Soybeans S20-T6 brand, shown here in a customer’s field, for its ability to withstand SDS pressure.

First-generation Farmer is 100% Syngenta Loyal

SyngentaAgronomy — Sat, 03 Dec 2016 14:00:47 +0000

Francesville, IN: As a first-generation farmer, Ben Stoller may not have decades of family knowledge to lean on for advice on overcoming a cold, wet spring or beating back soybean cyst nematodes (SCN). Instead, he relies on the guidance and support of his Golden Harvest® Seed Advisors^™. It was Brian and Phil Huber, a father-son Seed Advisor team in Stoller’s area, who helped identify the hybrids and varieties with the highest likelihood of success in his fields. Now, 5 years after he first tried Golden Harvest Corn and NK® Soybeans, Stoller is a loyalist. “The products are good and reasonably priced, so I started using a little more each year,” he said. “Today, I plant 100% Golden Harvest Corn and NK Soybeans.” His decision has been validated during both easy and tough seasons. “I was a little concerned with the corn early on this year because it was a cold, wet spring, and the crop crusted over,” he said. “But I’m impressed – Golden Harvest hybrid G07F23 brand came through with a nice stand, and I saw yields over 200 bu/A. The moisture rate was under 20% for everything, so it was a blessing to not spend as much time drying.” On the soybean front, having his NK Soybean S39-C4 brand protected by Clariva® Complete Beans seed treatment, a combination of separately registered products including CruiserMaxx® Beans with Vibrance insecticide/fungicide seed treatment, has helped him overcome the threats of sudden death syndrome and SCN. “The seed treatments have such good disease packages, so my NK Soybeans stayed healthy and green all year,” Stoller said. “I had my best beans ever this year.” All photos are the property of Syngenta or are used with permission.

Hybrids Deliver Both Performance and Premiums at Harvest

SyngentaAgronomy — Sat, 03 Dec 2016 15:00:48 +0000

Havelock, IA: Brad Arnold wrapped up another successful harvest pleased with his corn’s performance this season – especially his Enogen® hybrids. The season started and ended with wet conditions, delivering approximately 10 inches of rain in Arnold’s region between Aug. 1 and Nov. 1. Even with the season’s challenges, Arnold said his Enogen corn stood perfect. “The crops dried down good,” he added, noting that his Enogen hybrid E109R3 brand ended up yielding 228 bu/A this season – approximately 20 bu/A higher than the regional average. Enogen corn is an in-seed innovation available exclusively from Syngenta, featuring the first biotech corn output trait designed to enhance ethanol production. It offers alpha-amylase enzyme directly in the grain, eliminating the need for ethanol producers to source liquid amylase and keeping the dollars they would spend elsewhere in their local communities instead. Enogen growers, meanwhile, are eligible to earn up to a 40-cents-per-bushel premium for Enogen grain delivered to participating ethanol plants. For Arnold, the combination of performance and improved return on investment has made Enogen corn a staple on his farm. “Enogen performs well – it yields right along with the other hybrids,” Arnold said. “I personally just don’t see any reason not to plant it.” All photos are the property of Syngenta or are used with permission.

Hurricane Proves No Match for NK Soybeans

SyngentaAgronomy — Thu, 01 Dec 2016 22:04:53 +0000

Bishopville, SC: Hurricane Matthew reached 160 mph at its peak this fall, but by the time the storm made it to South Carolina, the winds fortunately started to slow. Even so, Dean Elmore’s farm – nearly 100 miles off the coast – saw 50 to 60 mph winds. Elmore’s NK® Soybeans, however, held strong. “They leaned over a little bit, but that’s to be expected after a storm with winds like that for 12 to 14 hours,” Elmore said. “We were able to get our NK Soybeans back up, and harvested them just fine.” Elmore planted NK Soybeans S52-Y2 and S74-N3 brands, both of which were protected by Avicta® Complete Beans 500 nematicide/insecticide/fungicide seed treatment. Avicta Complete Beans 500 offers triple pest protection during the critical early growth stages to help maximize yield. “All of my NK Soybeans came out of the ground really well and together, they yielded well – about 65 bu/A,” Elmore said. “I also grew some competitor soybeans, but NK Soybeans had a yield edge on them.” Although Elmore doesn’t plan on planting soybean acres next season because of a 5-crop rotation plan that includes wheat, corn, peanuts and sorghum, 10 years of positive experiences with NK Soybeans mean he expects to come back to the brand in 2018 – hopefully without a hurricane to deal with.

Moisture No Match for Crop Protection Technologies

SyngentaAgronomy — Sun, 04 Dec 2016 14:01:44 +0000

Blooming Prairie, MN: A wet, saturated season created a real threat of disease for Ryan Larson’s NK® Soybeans – making it the perfect opportunity to test Trivapro® fungicide’s abilities. Featuring three active ingredients, Trivapro delivers long-lasting disease control and crop enhancement benefits to maximize yield potential – advantages that Larson ended up experiencing first-hand. “Trivapro did a very good job of keeping my soybeans clean and disease-free,” Larson said. “It was the right way to go, especially with the number of days of residual.” Studies show that Solatenol® fungicide, one of the active ingredients in Trivapro, is 10 times more potent than other SDHIs on the market and delivers longer-lasting control. Crop enhancement benefits maximize yield potential and harvest efficiency by promoting stronger stands, healthier roots and fuller pods. “We had a lot of wind throughout the growing season this year, and it seemed that Trivapro helped provide good standability,” he said. “I would definitely recommend it to other growers based on my experiences.” This year also left him impressed with another Syngenta crop protection product: Acuron® corn herbicide. After watching the impact of other herbicides slip over the past few years, the control from Acuron was refreshing. “Acuron has proven itself in the field against tough-to-kill weeds,” Larson said. “It’s very good on giant ragweed, waterhemp and lambsquarters, and the application flexibility is a good benefit to have.” In addition to growing his own crops, Ryan Larson works as a retailer with Central Farm Services in Blooming Prairie, MN.

‘It’s the Seed’: NK Soybean Yields Keep Rising

SyngentaAgronomy — Mon, 05 Dec 2016 21:25:47 +0000

Britton, SD: According to third-generation farmer Kevin Jones, weather was the biggest obstacle to producing good yields in 2016. A hotter-than-average summer combined with regular windstorms but only sporadic rains pushed Kevin Jones’ crops to their stress threshold. Even so, his corn and soybeans yielded strong – continuing a trend Jones has noticed over the past decade. “It’s the seed,” he said. “Our yields have steadily increased every year since I started farming.” Jones said NK® Soybeans S10-P9 and S14-J7 brands yielded about 12 bu/A higher than average, an outcome he partially attributed to their standability. “Our crops were stressed most of the season. If we didn’t get a windstorm in the morning, it was the afternoon,” Jones said. “But the health and stand of my NK Soybeans were stronger than others.” This type of performance makes him happy to be a grower. “I love farming and working with family every day. I get up early because I can’t wait to get at it!” he laughed. Kevin Jones is proud to be a grower. “It’s in my blood,” he said. “I’ve never done anything else and don’t desire to do anything else.” All photos are the property of Syngenta or used with permission.

MN Grower Finds Positive Yields Amid Flooded Fields

SyngentaAgronomy — Mon, 05 Dec 2016 21:35:15 +0000

McLeod County, MN: When some of your fields looks less like farmland and more like lakes (ducks and all), you know you’ve had a wet season. As Chad Doering slowly plotted his way through muddy fields in his combine, he did what he could to salvage his harvest. “Conditions were all over the place,” Doering said. “Some fields were wetter than others. Some had lakes in them; other fields were nice and dry.” Although field conditions were inconsistent, Doering said his Golden Harvest® Corn hybrids’ performance was not. The consistent standability and resulting yields offered a satisfying payoff, with his yield monitor averaging 180-185 bu/A. Doering suspected that his tires spinning in mud made this number lower than his true yields, which he estimated at 195 bu/A. “Golden Harvest has performed well,” Doering said. “We’re happy.” All photos are the property of Syngenta or used with permission.

Green Stem Disorder Affecting Midwest Soybeans

SyngentaAgronomy — Tue, 06 Dec 2016 14:00:46 +0000

Reports of green stem disorder sightings in Missouri have picked up as harvest wraps up. Green stem is present when stems that should otherwise be brittle and brown at the end of a growing season remain moist and green. According to the University of Illinois Extension, while pods mature and soybeans become ready for harvest, these green stems will not reach the same point of maturity. Green stem also makes it difficult to harvest soybeans in a timely manner. If mature seeds are left in the field, seed quality can decline and result in an unsellable product within just a few weeks. A disease that affects all soybean growing regions, green stem disorder is exceedingly difficult for growers to predict. According to the Iowa State University Extension, the cause of green stem disorder is unknown and might be due to a combination of factors, including:

Disease infection
Insect damage
Lower fall humidity levels and higher fall temperatures
Soil moisture stress

As researchers continue to work to diagnose the cause of green stem, the disorder is sometimes misdiagnosed as the strobilurin-greening effect brought on by the use of fungicides. Green stem disorder and the strobilurin-greening effect have drastically different effects on soybean yields. While green stem disorder can negatively impact soybean harvests, the strobilurin-greening effect extends the window for photosynthesis and can help plants produce larger beans, fuller pods and improve soybean retention. This benefit comes with using a fungicide containing strobilurin, such as Trivapro^® fungicide. Unfortunately, once green stem is found in a field, there is little that growers can do to mitigate its effects. But researchers continue to study this elusive disease and search for a treatment.

Florida: Why Herbicides Fail During Drought

SyngentaAgronomy — Mon, 12 Dec 2016 14:00:15 +0000

According to the University of Florida IFAS Extension, there are 2 main reasons why herbicides fail in drought situations:

Less herbicide absorption through the leaf surface
Slow/stopped translocation of the herbicide within the plant

This is normal, as a plant’s defense mechanism during drought is to close the stomata to reduce water evaporation and conserve resources. The weed may also protect itself even further by increasing the waxy layer covering the leaf surface to decrease water loss. Dr. Ramon Leon, University of Florida IFAS Weed Science Specialist, said ironically healthy weeds are needed for herbicides to be effective. When weeds are stressed by drought, herbicide uptake by leaves and roots, and herbicide movement within the weed are reduced, so it’s more difficult for the herbicide move within the plant to kill it.

Post-Harvest Weed Control Assessment is Critical

SyngentaAgronomy — Wed, 14 Dec 2016 14:00:46 +0000

Post-harvest is an important time to evaluate weed control in corn and soybean fields. When planning for 2017, be sure to look back at 2016 weed control failures and successes, and adjust weed management programs to win the battle against troublesome weeds. A season-long weed management battle plan is essential to protecting valuable crop investments. Deploy these tactics to avoid herbicide resistance and give your crops a leg up in 2017:

Use fully labeled herbicide rates
Diversify herbicide modes of action
Rotate crops in successive seasons
Overlap pre-emergence and post-emergence residual herbicides

Resistance management requires full-season attention. Plan early and use multiple modes of action in your 2017 herbicide program to control weeds, achieve higher yield and fight resistance all season long.

Fight Resistant Weeds in Wheat and Barley

SyngentaAgronomy — Wed, 07 Dec 2016 16:30:29 +0000

Yield-robbing weeds infest wheat and barley fields, compete with crops and can ultimately impact yield potential and crop quality. Resistant weeds can compound this problem for decades. Because of this, it’s important to be proactive and fight herbicide resistance to avoid weed resistance problems for years to come. To help combat this problem, Syngenta recently announced the federal registration of Talinor™ herbicide, a new option for wheat and barley growers to manage weed resistance and control damaging broadleaf weeds. Talinor:

Controls more than 45 troublesome broadleaf weeds, particularly those resistant to ALS-inhibitor, synthetic auxin and glyphosate herbicides
Combines 2 active ingredients (bicyclopyrone and bromoxynil) with 2 modes of action for effective weed control
Offers flexible crop rotation and a wide application window
Provides excellent tank-mix flexibility and is an ideal mix partner with Axial® brand herbicides for one-pass grass and broadleaf control
Is conveniently packaged with CoAct+™ additive to deliver optimum performance
Is an ideal fit for growers in the Northern Plains and the Pacific Northwest

Proactive practices can help minimize the evolution of herbicide resistance in wheat fields. Remember when applying herbicides that timing, using the full recommended rates and utilizing different modes of action will help fight herbicide resistance and ultimately help grow more wheat.

Once Harvest Ends, Negotiations and Planning Begin

SyngentaAgronomy — Fri, 09 Dec 2016 15:49:02 +0000

Charles City, IA: Rain may have delayed it, but harvest across the Midwest is essentially complete. Now growers are turning their attention to the next task at hand: the 2017 season. For many of those who depend on rental farmland, this will require negotiating with landlords. Growers enrolled in the AgriEdge Excelsior® program have precise, data-driven tools to carry with them into those discussions. Andy Johnson, a retailer and grower in Charles City, Iowa, depends on the program’s Land.db® software to map out everything he spends on his farming operation. “It’s an effective tool for showing my landlords what my actual costs are,” he said. “It breaks it down for them and shows exactly how much fertilizer I am putting on their farms, as well as the expense.” But the software’s usefulness in negotiations goes far beyond the landlord/tenant relationship. Johnson also employs Land.db data in discussions with his lender. “It’s great to be able to go to a banker with a printout in a professional format,” he said. Rent and lending data assist Johnson as he maps out a strategy for 2017. Right now, he is reviewing 2016 season – from fertilizer, herbicide and water inputs, to harvest, yield and land usage. The program also shows Johnson exactly which fields were the most profitable, and highlight any that lost money. When planing for 2017, consider current record-keeping processes. Talk to your Syngenta representative to see if enrolling in AgriEdge Excelsior could improve your record keeping, planning, negotiations and product selection.

Defend Against Alfalfa Diseases and Insects

SyngentaAgronomy — Fri, 16 Dec 2016 14:00:02 +0000

As the 2017 alfalfa season approaches, be sure to assess fields early for insects and diseases. Many insects, especially in the early stages, have similar appearances and can be easily confused with one another. Improper identification of insects can lead to improper management decisions, which can be a detriment to alfalfa crops. Likewise, alfalfa diseases can reduce yields, forage quality and stands. Creating a preventive management plan and protecting crops early is crucial to reaching higher, more stable yields and elevating overall performance. Utilizing alfalfa varieties with top-performing agronomic characteristics, as well as insecticides and fungicides, when necessary, can help alfalfa crops start strong and protect yield potential, ultimately maximizing return on investment.

Ohio: Are Your Wheat Plants Purple?

SyngentaAgronomy — Mon, 19 Dec 2016 14:00:33 +0000

Farmers in northwest Ohio have reported purple-reddish leaves on their wheat plants. What does this mean? According to the Ohio State University Extension, there 3 main factors that could contribute to this:

Environmental. The sudden shift to colder temperatures this year may have slowed plant growth and turned leaves purple.
Fertility. If plants have been purple for a longer period, phosphorus deficiency may be the cause.
Disease. Diseases such as barley yellow dwarf virus (BYDV) can also cause wheat plants to turn purple.

Georgia: Prepare for Kudzu Bugs in Soybean Fields

SyngentaAgronomy — Fri, 30 Dec 2016 14:00:39 +0000

According to the University of Georgia, Kudzu bugs have made their homes in soybean fields across the southeastern U.S. While they don’t cause damage every soybean season, when they do prevail they can cause yield losses between 20-60%. The University of Georgia recommends looking at Kudzu bugs as a cyclical pest. While we won’t see it every season, it’s still important to be ready if and when they do come back. Consider resistant soybean varieties when it’s time to select soybean varieties.

Soil Sampling for SCN Saves Soybeans

SyngentaAgronomy — Tue, 03 Jan 2017 15:01:20 +0000

Now that the 2016 soybean season is over, it’s easy to put the problems we encountered behind us. However, it’s important to remember the threats to future soybean fields, and prepare now to combat them. Unfortunately, the No. 1 soybean pest in the U.S. happens to be invisible to the unaided eye and does not show many, if any, visible symptoms. Soybean cyst nematode (SCN) attacks soybeans at the roots and quietly thwarts yields. Due to the absence of above-ground symptoms, oftentimes SCN yield damage is attributed to cultural or environmental conditions, according to the Iowa State University Extension. This can lead to a build-up of undetected SCN populations. This invisible damage means you could be unaware of your SCN problems. It’s important to submit soil samples to your local state extension to test for SCN presence. We also encourage you to develop a proactive management plan to protect soybean yields from SCN.

Stalk Quality and 2017 Corn Hybrids

SyngentaAgronomy — Thu, 05 Jan 2017 14:35:13 +0000

Thinking back to the 2016 harvest, how did corn hybrids perform when it came to stalk integrity and standability? If these topics were issues in your corn fields, here are some steps that can be taken immediately to help you in 2017:

Hybrid Selection: Hybrid selection is critical to helping seeds start strong. Choosing the right hybrid for your field’s soil types and environmental conditions can be the difference between good yields and great yields. This is especially true to help prevent deteriorated stalk health and to ensure crops reach their maximum potential. Check stalk strength ratings for hybrids using tools like the Golden Harvest® Corn product finder, and be on the lookout for hybrids with additional protection against below-ground insects like corn rootworm.
Crop Protection: Syngenta agronomists observed that crops where fungicides were used experienced fewer standability issues and performed better under pressure from diseases like northern corn leaf blight. When choosing a fungicide package for the upcoming growing season, it’s important to keep in mind that this added protection can help stalk health in the field.

How to Take Soil Samples for SCN

SyngentaAgronomy — Mon, 09 Jan 2017 14:00:31 +0000

We’ve mentioned before that soil sampling is key to saving soybean yields from soybean cyst nematode (SCN). But which method should you use, and when should you use them? Timing There are 2 recommendations for how often to perform soil sampling for SCN: either every 3-5 years or every second or third soybean crop cycle. About the only time not recommended for SCN sampling is when the soil is muddy, as this condition makes the process of egg extraction more difficult. Depending on what crop was grown previously, growers may want to consider a couple of different schemes for where to take samples from in the field:

If growing beans after beans, samples should be taken from directly within the harvested crop rows.
If the previous crop is a non-host, like alfalfa or corn, wait until after the fall tillage and sample irrespective of the row.

With either one of those schemes, sample the top 8 inches of soil. The more soil cores that are taken from an area, the more accurately the SCN level will be represented. Grid Sampling vs. Conventional Sampling SCN is not uniformly distributed and shows up in hot spots through fields; because of this, take sub-samples combined from across a field. There are 2 types of soil sampling that can help determine the level of infestation: grid sampling and conventional sampling. Grid sampling is performed based on the process already in place for soil fertility sampling. Since GPS has enabled much more targeted fertilizer applications, many soil cores are taken from a systematic grid pattern across a field to determine where soil is not as fertile and where it is very fertile. As those cores are pulled for fertility sampling, an extra core or 2 are pulled and kept in a separate bucket. The accumulation of those samples in a composite from across approximately 20 acres is the basis for the SCN sample. In conventional sampling, the grower would take 15-20 cores in a zigzag pattern from an area that represents about 20 acres or fewer, including areas near waterways, trees or any natural agronomic features of the land. The goal of each sampling method is to collect samples from many areas of the field. Where to Send Soil Cores for Testing Soil samples contain biological material, and for that reason, you may not ship soil or plant material across state lines without proper USDA phytosanitary permits. Samples should be sent to the home state's land-grant university nematode lab. We recommend that growers stick close with local lab recommendations. Nematode lab websites also contain useful information for growers on management and maintenance, along with sample submission forms for the nematode clinic or lab. You can visit the websites of nematode labs of land-grant universities at the following websites:

Spinach Growers: Downy Mildew Got You Down?

SyngentaAgronomy — Tue, 10 Jan 2017 14:10:36 +0000

You’re not alone. Downy mildew is the most damaging disease in spinach production almost everywhere spinach is grown. Because of the natural layered way spinach grows, and the added density of plants in most fields, conditions are ideal for this disease to spread rapidly. Therefore, it’s important to be proactive in management practices. The pathogen that causes downy mildew, Peronospora farinosa f. sp. spinaciae, thrives in wet, cool conditions, making cultural controls such as reducing leaf wetness a key preventive approach. Additionally, using a fungicide like Orondis® Ultra, currently sold as a multi-pack product combining Orondis Ultra A and Orondis Ultra B, offers excellent control of downy mildew in spinach. Orondis Ultra fungicide is currently approved for use in 46 states, with approvals pending in California and others. It combines 2 products, Orondis and Revus® fungicides, into a game-changing tool for control of downy mildew in spinach. To learn whether Orondis Ultra is approved for use in your area, visit this page. For more information, talk to your local Syngenta representative.

2016 Wheat Season Report

SyngentaAgronomy — Fri, 06 Jan 2017 16:29:50 +0000

The National Agriculture Statistics Services of the UDSA reported that U.S. growers produced the largest wheat crop since 2008/2009, with 2.31 billion bushels. This is a 13% increase from last year and 10% above the 5-year average yield. As winter and spring wheat harvest data continues to be finalized*, here is an overview of how growers described this past season in wheat fields across the Dakotas: Product Performance vs. Herbicide Resistance The biggest weed issue Dakota wheat growers saw was the increase of kochia in their fields. There are 2 sides to this weed control story – did growers try to save money upfront on their herbicide package (i.e. going from name brand herbicides to generic products/ALS-inhibitors), or did weeds develop a tolerance to the product? It could be either of these issues, but when it comes to herbicide resistance, remember to be proactive in order to maximize weed control. That includes knowing which product fits best and managing weed escapes. Rust on the Rise Stripe rust epidemics have been rare in the Dakotas, but we’ve seen increase in this disease since 2011. Stripe rust is not the type of disease that shows up and then goes away easily. In April, stripe rust was found in Miller, SD – only 100 miles away from the ND border, which made us rethink stripe rust’s overwintering patterns. To combat stripe rust, growers should purchase a fungicide package that contains triazoles, strobilurins or mixed modes of action. Then, when deciding to make a fungicide application, consider the growth stage, level of rust incidence in a field, and future weather conditions. Insecticide Effectiveness There were also reports of wheat streak mosaic virus in spring wheat. The unfortunate side of this is there are no chemicals currently on the market to manage the mite or virus directly. Because of this, it’s important that growers destroy all volunteer wheat plants and grassy weed hosts before planting a new wheat crop and that they plant at the recommended seeding dates. We continue to receive many questions on wheat stem sawfly as well. Unfortunately, there is no good way to control this insect. Growers should be wary of wheat stem sawfly because it bores into the joints of wheat straws which weakens and causes breakage. The best way to combat this insect is to plant a certified seed variety with tolerance to sawfly. Growers also saw wireworms in their fields. In the 2017 season, growers should continue to pay attention to this insect, as it is a multi-year pest. Having thiamethoxam in your seed treatment package helps suppress wireworm and other insect populations. High Levels of Vomitoxin ND recorded large levels of vomitoxin in durum and spring wheat in the northern part of the state. Some growers had fields that were completely burned to the ground. Growers who produced a wheat crop with vomitoxin saw a large price discount at local elevators, with some even being turned away. High humidity and moisture can create the perfect condition for this toxin. Fusarium, a disease that produces vomitoxin, may have also been a key player in the high levels reported in the state. To protect against Fusarium and vomitoxin, growers should choose a certified variety with this protection and also use a seed treatment with fludioxonil to protect against soilborne and seedborne diseases. It’s also important to scout fields regularly to track the presence of Fusarium and other diseases. As spring planting season approaches, it’s important to watch weather patterns and plan ahead to protect wheat fields from threats that diminish wheat quality and yield potential. Utilizing an integrated management approach helps boost crop productivity and grow profitable wheat.

Importance of Certified Wheat Seed vs. Saving Seed

SyngentaAgronomy — Wed, 11 Jan 2017 14:00:10 +0000

Certified seed is defined as seed that has passed an inspection and seed testing process regulated by government agencies, and meets those specified variety standards. Many farmers purchase certified seed for planting and then save harvested seed for 2 or more consecutive years before buying fresh seed. What’s the problem with this method? The further removed saved seed is from the original certified seed variety, the greater the risk of varietal impurities, poor seed germination, diseased seed, and volunteer crops and weeds. Although the initial cost of saving seed is lower than purchasing certified seed, doing so may lead to a need to buy more seed and/or apply more crop protection products if the saved seed doesn’t perform as well as expected. Growers who purchase certified seed are receiving a product that has gone through the rigors of the certification process, was sourced from clean production fields, has passed inspections for varietal purity and germination viability, and is free of weeds and other contaminants. Additionally, by running a seed producer’s harvested seed crop over sophisticated cleaners and gravity tables, seed houses can select for the largest, heaviest kernels, which typically contribute to more vigorous plants that can emerge faster and better handle early-season stresses. When a grower purchases certified seed, it comes with the guarantee that the seed is true to type. New advancements in seed technology, less risk of seedborne and soilborne disease infections and low germination rates are reasons growers should plant certified seed. If that’s not enough, the resulting investment helps increase yield and profit potential – more and more growers are beginning to recognize that enhancement. At the end of the day, it’s only about a couple of dollars per acre and considered a strategic part of a grower’s overall business plan. ¹ Source: Food and Agriculture Organization of the United Nations Submitted by Corey Dathe, AgriPro® wheat key account lead from Syngenta in the Northern Plains Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Winter Annual Weeds and SCN: A Problematic Pair

SyngentaAgronomy — Thu, 12 Jan 2017 21:09:49 +0000

Alone, winter annual weeds can cause a headache for soybean growers the following season by potentially leading to delayed planting, lower yields and increased seedbed preparation costs. Combined by acting as the overwintering host to soybean cyst nematode (SCN), the most economically damaging soybean pest in the U.S., these weeds may further lower soybean production. The Purdue University Extension identified 6 winter weeds that can serve as hosts for SCN:

Purple deadnettle
Henbit
Field pennycress
Shepherd’s purse
Small-flowered bittercrest
Common chickweed

SCN juveniles feed on the roots of these weeds. On some weeds, such as purple deadnettle (pictured above) and henbit, SCN can complete several life cycles before planting begins the following spring. Greenhouse studies ranked purple deadnettle and henbit as strong hosts because SCN reproduction on those 2 weeds either equaled or exceeded reproduction on SCN-susceptible soybeans. Controlling these 6 weeds should be an important goal within any farm’s SCN management program. Scout fields now for winter annual weeds and remove them prior to planting. As the next step in an effective SCN management program, growers should plant and enhance them with a seed-applied nematicide like Clariva^® Complete Beans seed treatment, a combination of separately registered products. Like most comprehensive crop protection programs, SCN management requires early action for better future yields.

Six Tips to Manage Herbicide Resistant Weeds in Soybeans

SyngentaAgronomy — Fri, 13 Jan 2017 16:17:03 +0000

A herbicide resistance problem doesn’t develop overnight. Usually, it’s the result of high selection pressure put on a weed population over the course of several years. By repeatedly applying the same herbicide or several herbicides that use only a single effective mode of action (MOA), or applying a herbicide at less than a labeled rate, growers can accidentally create that pressure. The results of herbicide resistance can be extremely costly. In the long run, taking a proactive approach to weed management is the most effective and economical way to tackle this challenge. To help manage herbicide resistant weeds, we recommend the following best management practices:

Plant in a seedbed free of problem weeds, especially where Palmer amaranth is the major issue. In this case, use tillage or chemical burndown with products like Gramoxone^® SL 2.0 herbicide (Geography: 100 mile radius (AR, West TN, Bootheel MO).
Use full rates of herbicides with different mechanisms or effective MOA prior to planting and throughout the growing season.
Optimize soybean growth environment with a combination of cultural and management practices that promote healthy vigorous plant growth such as CruiserMaxx® Beans with Vibrance® seed treatment, a combination of separately registered products, and appropriate nutrition.
Overlap residual herbicides from burndown to canopy-closure applications to ensure minimum escapes during the growing season. As demonstrated in the photo below, Boundary® 6.5 EC herbicide pre-emergence provides residual activity with 2 MOA and excellent activity on most problem grass and broadleaf weeds.
Use overlapping residuals by combining glyphosate post-emerge together with a product like Prefix® herbicide that has 2 MOA and is effective on most problem grass and broadleaf weeds.
Use registered formulations of Dicamba, if necessary, at the recommended rate to clean up escapes of weeds like Palmer amaranth before they exceed 2” in height.

Start Strong: Protect Potatoes from Pests

SyngentaAgronomy — Tue, 17 Jan 2017 14:00:12 +0000

According to Iowa State University, half of potatoes planted each spring are infected with some sort of plant disease. Diseases cut down stand, injure roots, and can disfigure the potato – all of which reduce yield and return on investment. To help protect potato crops from the moment of planting, we recommend using a seed treatment. Seed treatments can help increase yields, at only a small expense, according to experts at Iowa State University. CruiserMaxx® Vibrance® Potato insecticide/fungicide can help deliver comprehensive control against Rhizoctonia, Helminthosporium and Fusarium. Additionally, the insecticide component of CruiserMaxx Vibrance Potato provides exceptional protection against key insects, including Colorado potato beetles, aphids, potato leaf hopper and potato psyllid. It also delivers the Cruiser Vigor Effect, an increased level of plant vigor and health beyond the standard plant response to an insecticide. Since a strong root system is the foundation of plant vigor and good crop stand, it’s important to protect roots from the start.

Sudden death syndrome (SDS) has the potential to significantly reduce soybean yields. The majority of U.S. soybean growers are affected by SDS 1 in every 4 years; however, the actual impact will vary significantly per field and year. Fusarium virguliforme, a fungus that lives in the soil, causes SDS and can infect soybean roots soon after emergence. It develops in the roots and sometimes in the lower stem of the plant. The pathogen can survive in soybean debris and soil for many years, even with crop rotation. Early planting, cool soil temperatures and high moisture levels promote disease development. While management options are limited, there are measures you can take to proactively reduce the risk of SDS outbreaks:

Plant fields without a history of SDS first. Fields with a history of SDS should be planted later because young, slower growing plants are more susceptible to infection.
Reduce soil compaction.
Manage soybean cyst nematode (SCN) populations, which have the potential to limit SDS severity.

Using a soybean variety with tolerance to SDS can also help manage this disease. NK® Soybeans have proven tolerance to SCN, SDS and other pests and diseases. Another way to combat SDS is to use a seed treatment such as Clariva® Complete Beans, a combination of separately registered products, that offers season-long SCN protection and helps reduce damage from SCN-related diseases including SDS. Additionally, Mertect® 340-F seed treatment fungicide with direct activity on SDS provides a double mode of action to help manage the disease. When it comes to SDS, it’s important to utilize all the tools in your toolbox. Start the season strong – be proactive and have a disease management plan.

Unexpected Pests Can Eat Into Corn Profits

SyngentaAgronomy — Tue, 17 Jan 2017 19:41:03 +0000

Planting corn hybrids without insect control traits may seem like an easy cost-savings. However, pest pressure during the season is unpredictable and can become a costly problem. One pest that has been spreading and causing damage throughout the Midwest is Western bean cutworm (WBCW). Historically, WBCW was only a challenge for growers in the Western Corn Belt, but over the last few years, WBCW has progressively spread into other geographies. A recent WBCW outbreak was documented in a field in Shelton, Nebraska (pictured above). When left unchecked, the damage caused by WBCW can be substantial. The kernel damage caused by WBCW feeding can lead to the development of molds, which in turn can produce mycotoxins, including aflatoxin, which can reduce the quality of grain. Reduced grain quality can lead to lower prices at the elevator and for feed-on-farm operations, it can lead to decreased grain nutritional value, which can negatively impact livestock performance. To help protect corn hybrids against the effects of damaging pests like WBCW, it’s important to choose a high-performing insect control trait. The Agrisure Viptera® trait delivers the most comprehensive control of above-ground insects, including WBCW. The photos below show how effectively Agrisure Viptera hybrids stood up against WBCW pressure in the Shelton, Nebraska field. The corn ears from hybrids with the Agrisure Viptera trait have noticeably healthier ears with more kernels and less insect damage. Agrisure Viptera trait stacks are an effective tool to fight outbreaks of pests like WBCW that can eat into profits. Defend your hybrid investments by planting hybrids with the Agrisure Viptera trait for the most comprehensive corn insect control in the industry and for more, high-quality grain and increased profit potential.

Corn Weed Management Requires a Full-Season Plan

SyngentaAgronomy — Thu, 19 Jan 2017 14:24:07 +0000

Weeds depend on routine to survive. Weed management programs that rely on 1 herbicide increase the potential for herbicide-resistant weeds to develop. As a result, the herbicides used to control these weeds may become ineffective. When preparing for the 2017 growing season, keep these tactics in mind to avoid herbicide resistance:

Use fully labeled herbicide rates
Diversify herbicide modes of action
Rotate crops in successive seasons
Overlap pre-emergence and post-emergence residual herbicides

For best weed control, we recommend a 2-step herbicide program, including pre- and post-emergence products.

Acuron® and Acuron Flexi corn herbicides help put you back in control of tough weeds by delivering more residual control of more weeds with a single product.
Halex® GT post-emergence corn herbicide controls emerged weeds and delivers residual control of grass and broadleaf weeds until crop canopy.

Root Health is Key to Successful Wheat Crops

SyngentaAgronomy — Fri, 20 Jan 2017 14:00:01 +0000

Experts say that 80% of all plant problems start with soil and root damage caused by underground pests and diseases. Their effect often goes unnoticed until the end of the season, resulting in significant crop damage and yield loss. Lush and robust wheat fields start with durable, deep, fiberous and disease-free roots. These roots absorb important nutrients and moisture that produce healthier plants with stronger yield potential, which is why growers should keep their wheat’s root health top of mind when preparing for the season. But what does “root health” mean? Root health can be defined as:

A root system with very little disease infection
A root system that more efficiently takes up water and nutrients
A plant with stronger stems and foliage that better withstands environmental stress

Healthy roots help crops better cope with stress and build enough leaf area to produce higher yields. They also help winter cereals survive harsh weather conditions for a strong growth start in spring and provide optimal conditions for spring sown cereals to maximize yield in their short growing cycle. When thinking about the 2017 season, keep root heath at the top of mind. Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Pest Alert: Stripe Rust Confirmed on Nebraska Wheat

SyngentaAgronomy — Mon, 23 Jan 2017 14:00:21 +0000

NEBRASKA: According to the University of Nebraska Extension, stripe rust was confirmed this fall throughout wheat fields in the Nebraska Panhandle, specifically in Kimball and Banner counties. For the third year in a row, stripe rust has been identified on fall-planted wheat in the Panhandle. The previous 2 years, disease outbreaks occurred in numerous locations, suggesting that Nebraska could be at risk for another disease outbreak this season. Scouting for this disease will be crucial in the coming months. Be sure to stay particularly watchful during cool, wet periods, as this is when spore germination can occur rapidly, and when this disease thrives. Controlling the disease early is important for maintaining crop health for optimum yield potential. If stripe rust is found in your wheat, control measures should be taken before it spreads. We recommend applying Trivapro^® fungicide which provides long-lasting efficacy on stripe rust on wheat. One application of Trivapro exhibits greater residual control of stripe rust on wheat compared to other brands with 1-pass and 2-pass programs. It’s important to regularly scout fields to track the presence of stripe rust and other diseases. Being proactive about crop protection will help maximize profit potential and ultimately help grow more wheat.

Threats to Wheat Root Health

SyngentaAgronomy — Thu, 26 Jan 2017 14:00:40 +0000

We previously discussed how root health is key to a successful wheat crop. Let's take a deeper dive into the many factors that contribute to poor root health and decreased crop productivity:

Drought. In many regions around the world, cereals are grown in areas subject to short-term drought periods, which leads to troublesome yield inconsistencies.
Reduced tillage/zero tillage/irrigation. Good land practices favor the prevalence of root diseases.
Rhizoctonia quickly infects germinating seeds and young seedlings, and nibbles away at root tips.
Pythium can cause lesions around the root which leads to seedling collapse.
Fusarium infects the roots and eventually spreads to the crown.
Wireworms threaten crop yield and quality by attacking root systems.
Limited crop rotation impacts root health by creating a more hospitable soil environment for diseases and contributes to the “green bridge” effect.

This reinforces the need for strong and fast root development early-on to help ensure enhanced water and nutrient uptake. By incorporating preventive measures – including best management practices and seed treatment applications – growers can help ensure healthy root systems and get their crops started on the right foot.

The Watermelon Disease That Occurs Without Warning

SyngentaAgronomy — Mon, 30 Jan 2017 14:00:22 +0000

Gummy stem blight is a highly destructive, foliar fungal disease that can cause yield losses of more than 50% in watermelon crops. It’s caused by the fungus Didymella bryoniae which survives on seeds, weeds, volunteer cucurbits and plant debris from previously infected crops. According to the University of Florida IFAS Extension, the fungus can infect watermelons at any growth stage – from seeding to mature vine. Unlike other diseases, gummy stem blight is a major problem because it can occur without warning. The impact of gummy stem blight can be minimized if addressed in a timely manner that includes fungicide applications. For control of gummy stem blight in watermelon crops, we recommend a fungicide such as Aprovia® Top. Aprovia Top contains Solatenol® fungicide and the highly effective difenoconazole which provides excellent preventive activity and broad-spectrum control of gummy stem blight. In addition to utilizing a fungicide, it’s also important to implement a proactive management plan – from seed to storage.

Protect Your Return: Prevent Wheat Diseases Early

SyngentaAgronomy — Tue, 31 Jan 2017 14:03:34 +0000

With many threats to wheat root health, it important to be proactive in management decisions. Particularly, stopping damage caused by Rhizocotnia, Pythium and Fusarium as early as possible is critical to helping ensure optimum root health and maximum yield potential in cereals. To get ahead of these diseases and help crops develop with healthy, efficient root systems, we recommend the following to growers:

Plant certified seed. When available, select varieties with genetic tolerance.
Monitor soil fertility levels. Balanced soil fertility is extremely important to mitigate plant stress.
Rotate to a non-host crop to help break the disease cycle.
Plant into well-drained soils. Soilborne diseases thrive in wet conditions.
Destroy any green residue in fields at least 2 weeks before planting begins to eradicate the “green bridge” effect, break disease cycles and reduce chances of soilborne pathogens carrying over from past seasons.
Continuously scout fields for symptoms of soilborne pathogens to manage diseases early.
Apply a seed treatment to protect crops from the start. Fungicide and insecticide seed treatments help prevent the spread of plant diseases and keep insects at bay.

Choosing an early disease management plan, best variety and seed treatment is key to steering clear of soilborne pathogens and underground insects, which provides growers with the best chance for success. Following best practices, monitoring fields and speaking with area crop consultants, agronomists and retailers can help make sound decisions for getting your crop off to a solid start this season.

Which Leafroller Species is in Your Apple Orchard?

SyngentaAgronomy — Wed, 01 Feb 2017 21:36:52 +0000

According to Washington State University, there are 2 types of leafrollers commonly found in Washington apple orchards:

Pandemis leafroller (PLR)
Obliquebanded leafroller (OBLR)

If left uncontrolled, both chew through apple leaves and web together leaves and flowering parts of the buds. As larvae grow, they move to feed on the growing shoots, and sometimes continue to feed on the fruit – causing extensive damage and scabbing. Although they may seem similar at the egg and young larvae stages, it’s important to distinguish the differences between the 2 species so you can tailor your management plan appropriately. As larvae mature, the differences are more easily spotted. Here are some tips to scout for PLR and OBLR:

PLR larvae have a light green to light tan head and a light green thoracic shield
Mature OBLR larvae have a brown to black head capsule and a thoracic shield that varies from brown to dull green
The sides of the OBLR thoracic shield are dark brown to black and the leading edge is white or cream
AdultPLRs are a tan colored moth, 1/2 to 3/4 inches long with a banding pattern on the wing
OBLR moths are larger and darker than the PLR
The leading and trailing edges of the OBLR wing bands are darker than the rest of the wing, not lighter as on the PLR

According to Washington State University, the best strategy to manage leafrollers is to be proactive and control the larvae of the overwintering generation in spring. Experts recommend utilizing insecticide applications in the delayed-dormant period for apples to give the best control of PLR. Additional management tips can be found here for controlling PLR or OBLR as larvae or adults.

Seven Strategies for Second Year Soybeans

SyngentaAgronomy — Thu, 02 Feb 2017 14:00:44 +0000

Thinking about planting soybeans 2 years in a row? According to AgWeb and University of Wisconsin Extension researchers, this is not a recommended practice. However, if farmers choose this route, here are 7 tips they should adopt:

Switch up your varieties and choose strong disease resistance traits to match already known problems in your field
Test for soybean cyst nematode (SCN) and choose SCN-resistant varieties - SCN thrives in multi-year soybean rotations
Scout fields earlier and more intensely to stay ahead of disease problems
Lower seeding rates in fields where white mold has been a problem
Maximize the fungicide rates of your seed treatments
Use a pre-emergence herbicide, and multiple modes of action
Sample soil, and replace potassium if needed

Be Aware of Blueberry Gall Midge

SyngentaAgronomy — Fri, 03 Feb 2017 14:00:06 +0000

GEORGIA: According to the University of Georgia, reports of blueberry gall midge infestations have increased over the last couple of years. Although blueberry gall midge has historically been referred to as a rabbiteye problem, recently it has been a concern in southern highbush fields. Blueberry gall midge affects blueberries in major blueberry-growing states throughout the U.S. Capable of causing extensive damage, gall midge larvae feed on developing floral and vegetative buds in southern highbush blueberries. The infested buds appear dry and shriveled, and eventually disintegrate. Severe gall midge infestations can cause up to 80% crop loss if left uncontrolled. Timliness is key to managing gall midge infestations. Learn More >>> Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Mississippi: Control Italian Ryegrass in Corn before Planting

SyngentaAgronomy — Mon, 06 Feb 2017 19:20:56 +0000

Glyphosate-resistant Italian ryegrass has become a primary weed in corn fields in Mississippi. According to AgFax and Mississippi State University, it’s important to control the weed as early as possible with a targeted early burndown. A general rule of thumb is that if corn fields can be maintained weed free for the first 4 to 5 weeks after emergence, there will be no negative effects on yield due to weed competition. However, this rule applies only to weeds that emerge at the same time or immediately following corn - it doesn’t apply to glyphosate-resistant Italian ryegrass which is usually 12 to 24 inches tall during corn planting season in the Mississippi Delta. Research at the Mississippi State University Delta Research and Extension Center said that at least 2 herbicide applications are required for greater than 90% control of glyphosate-resistant Italian ryegrass.

Five Considerations for Planning Corn Weed Control Programs

SyngentaAgronomy — Tue, 07 Feb 2017 15:38:17 +0000

It might not look identical from state to state, town to town or even field to field, but weed pressure is just about everywhere. According to an Iowa State University Extension field agronomist, weeds are developing herbicide resistance faster than ever. Since no new herbicides are expected to solve these resistance issues in the near future, it’s important to use current options as effectively as possible. We recommend planning a comprehensive weed control program that includes cultural practices as well as herbicides. An Iowa State University Extension field agronomist suggests to consider the following when fighting weed resistance:

Use multiple modes of action
Select herbicides that are effective against your target weed
Use herbicides with residual control
Evaluate herbicide programs to determine that all products are used at effective rates
Plan for the long term

Season-long weed management is essential to keeping clean corn fields. Knowing that everyone has a unique set of challenges and that weed control can seem complicated, Syngenta offers the following herbicides to fight weed resistance:

Acuron® corn herbicide helps defeats tough weeds through its powerful combination of 4 active ingredients and 3 modes of action. Bicyclopyrone helps Acuron deliver a step change in weed management with greater consistency of control and broader spectrum control of weeds such as cocklebur, morningglory, ragweed and Russian thistle.
Lumax® EZ and Lexar® EZ corn herbicides contain 3 active ingredients and 3 modes of action and are also excellent choices for pre-emergence weed control in corn.
Halex® GT corn herbicide tank mixed with atrazine or dicamba helps controls grass and broadleaf weeds until crop canopy for total post-emergence weed control and long-lasting residual in glyphosate-tolerant corn.

Fight Herbicide Resistance in Soybeans

SyngentaAgronomy — Wed, 08 Feb 2017 16:02:04 +0000

From giant ragweed in Minnesota to Palmer pigweed in Mississippi, the reality is that there are a number of herbicide-resistant weeds in soybean fields across the U.S. Herbicide-resistant weed species can become a serious problem when a single herbicide or when multiple herbicides with similar modes of action are used repeatedly – this puts pressure on species to develop resistance. Uncontrolled weeds compete with crops for water, nutrients and sunlight, and have the potential to harbor insects and diseases, which can infest fields and negatively affect future crops. Because of the severity of this issue, creating a plan of action to build diversity into weed management programs is key to preventing further development of herbicide-resistant weeds. For optimal results in soybean fields, consider these approaches:

Identify the weed spectrum in each field.
Use herbicides with 2 different modes of action that target the same species to help combat resistance and effectively manage weeds.
Defend early soybean plants against weed competition by applying a pre-emergence residual herbicide that contains multiple modes of action.
Utilize a burndown application like Gramoxone® SL 0 where dense weed populations or scattered, hard-to-control weeds exist to help reduce early-season weed competition.
Use herbicides such as Boundary® and Prefix® for continued pre-emergence control. Each consists of 2 leading active ingredients and 2 non-glyphosate modes of action to provide fast and effective weed control.
Maximize herbicide diversity by following Boundary with Flexstar® GT 3.5 herbicide applied post-emergence over-the-top for continued weed control in glyphosate-tolerant soybeans.
Protect the PPO-inhibiting class of herbicides by using Flexstar GT 3.5 applied post-emergence to weeds 2 to 4 inches tall.

Combining cultural practices, such as crop rotation and tillage, with multiple, effective modes of action helps control weeds, reduce the weed seed bank, maximize diversity and fight herbicide resistance.

Southeast: Plan Early for Disease and Nematode Pressure

SyngentaAgronomy — Thu, 09 Feb 2017 14:00:13 +0000

Warm weather sets the stage for diseases and nematodes. With this winter’s mild La Niña and the resulting temperatures, growers can likely expect the extended the survival of “volunteer” crops and other factors to have a significant impact on diseases and nematodes for the upcoming season. Being proactive will be key. Pest Pressures: Whether it's nematodes, molds, or leaf spot diseases, warm weather helps pests thrive. According to the University of Georgia Extension and Southeast Farm Press, these are some of the insects, diseases and nematodes to look out for in the early 2017 season:

Thrips and tomato spotted wilt (peanuts)
Soybean cyst nematodes
White mold/stem rot (peanuts)
Northern and Southern corn leaf blights
Gray leaf spot (corn)
Fusarium (corn)
Diplodia ear rots (corn)
Frogeye leaf spot (soybean)
Anthracnose (soybean)
Southern root-knot nematodes (cotton)
Bacterial blight (cotton)
Leaf spot (peanuts)

How can you protect your crops from a plethora of pests? Variety selection plays an important part in a disease and nematode management program. Be aware of available disease and nematode resistant varieties and use an integrated management program that combines cultural practices, varieties with genetic resistance and fungicides:

Elatus^® fungicide provides excellent control of foliar and soilborne diseases in peanuts.
Avicta^®Elite Cotton Plus with Vibrance^® can help protect against early-season diseases, nematodes and difficult insects.
Trivapro^® fungicide helps protect corn and soybeans from diseases with preventative and curative activity.

Spring Wheat: Six Steps to Start Strong

SyngentaAgronomy — Mon, 13 Feb 2017 14:00:17 +0000

NORTH DAKOTA -- The first step toward growing more wheat is to start strong by choosing the best management practices and products to protect your investment. To help build the management plan that’s best for your field, consider the 6 steps below to get head of spring wheat problems and produce a more profitable crop:

1. 1. 1. Consult with your local agronomist to determine the ideal window for field preparation, planting and early-season scouting. Agronomists can also provide insight into how soil temperatures and current weather conditions may impact planting and early-season pest pressure.
    2. Implement an integrated crop management plan to ensure optimal stand establishment and protect against yield-robbing soilborne diseases.
    3. Clear fields of residual weeds. It’s important to establish a clean, weed-free field at least 2 weeks before planting wheat. If not, insects and diseases living in previous crop residue or remaining weeds can travel to newly emerging wheat and other spring crops. For optimum weed control, apply a quality burndown, preplant or preemergence herbicide to control a broad spectrum of broadleaf and grass weeds. Beginning the season with a clean field gives crops the best chance for a uniform start.
    4. Select fresh, clean, certified seed to address local challenges. Planting certified seed varieties helps ensure genetic purity, smoother plant-ability, seedling vigor and improved germination and emergence. Research shows that certified seed varieties consistently outperform saved seed in yield, quality and test weight.
    5. Protect the seed. Consider an insecticide seed treatment to provide protection against some of the most destructive wheat and barley insects, including wireworms, Hessian fly and aphids. As you consider an insecticide, you should also consider choosing a fungicide seed treatment, to protect against a broad range of seedborne and soilborne diseases, such as Rhizoctonia and Pythium.
    6. Scout early and often. Scouting is important at several stages of the growing season, and it’s best to start early. The first scouting trip should be to identify the pest species already present. After initial product applications, scout 2 to 3 weeks later to ensure good control has been achieved. Maintain consistent scouting practices throughout the season and increase the frequency as needed during times of high pest pressure.

By following these steps and being proactive, you can get ahead of problems and pests, and ultimately produce more profitable wheat. Submitted by Nathan Popiel, agronomic service representative.

Minnesota Grower Talks Agriculture, Consistency and Corn Herbicides

SyngentaAgronomy — Wed, 15 Feb 2017 15:45:34 +0000

Grower Todd Schwarz (Left) and Syngenta Rep Chris Schuler (Right) discuss the 2016 season. Over the years, we’ve seen a lot of changes across agriculture. From the curveballs Mother Nature throws our way, to pest outbreaks and the increasing development of herbicide resistance, there’s never a dull moment. We recently spoke with fourth-generation Minnesota grower and long-time Halex^®GT corn herbicide user Todd Schwarz during a short video exploring life on his Vernon Center, Minnesota, farm. The video offers a glimpse into a day in the life on Schwarz’s farm, the changes he’s witnessed since he began farming and the legacy he hopes to leave behind. For additional thoughts not included in the video, below is a Q&A taken from our recent interview with Schwarz: Q: How did you get started working in agriculture? Todd: I’ve been in agriculture my entire life. In high school I was in FFA. I even worked on the retail side for a while, helping farmers address their needs in that setting. Then I came to work my family farm and started being the one to actually produce crops. Q: What do you enjoy most about farming? Todd: I love being able to farm our family farm, work the land and have the independence of doing my own thing on a day-to-day basis. I would not enjoy being in an office from 8 to 5 on a daily basis. Q: What do you feel is the biggest stress in farming? Todd: For me, the biggest stress is weather. I don’t like having things outside of my control, but weather plays the biggest role in how our farm performs and what we’re able to do on a daily basis. Q: What made you want to partner with Halex GT on this video? Todd: I’m a man of few words, but when something works on my farm I tend to talk about it. Halex GT has helped control the grass and broadleaf weeds on my farm, and I use Halex GT over other brands because of the reliability and the consistency that it has given me. It is a no-brainer. You can put Halex GT out there and it goes and performs every season. It just works. Halex GT corn herbicide is for growers, like Todd, who are looking for reliable post-emergence plus residual control in glyphosate-tolerant corn. Halex GT controls emerged weeds and delivers residual control of grass and broadleaf weeds until crop canopy.

Soybean Aphid Predictions May Be Misleading to Growers

SyngentaAgronomy — Tue, 07 Mar 2017 14:00:35 +0000

Year after year, insects continue to threaten soybean yields. When it comes to soybean aphids, Midwest soybean growers should be prepared for anything this season. For many years, growers could safely predict soybean aphid populations using the every-other-year threshold model. With heavy soybean aphid pressure in 2016, growers might not expect aphids to become an issue in 2017. Yet, Dr. Kelley Tilmon, Associate Professor of Entomology at The Ohio State University says growers should be on guard. Based on 10 years of data, Tilmon shared in a recent Crop Life article where she says soybean aphids can in fact emerge every year given favorable conditions. In light of this research, growers should be prepared with the best management options. We recommend using Endigo^® ZC insecticide, providing quick knockdown and extended residual control of key foliar pest populations including soybean aphids. Using an insecticide treatment when soybean aphids reach the economic threshold is an essential component to improving yield potential to ultimately grow more soybeans.

Soil Fertility: The Basic Needs of the Plant

SyngentaAgronomy — Fri, 17 Feb 2017 14:00:42 +0000

Soil fertility is the foundation of all crop production. A successful crop is largely dependent on management of vital crop nutrients and successful fertility program starts with good planning. To start, it’s important to know that there are 16 essential elements that are needed by every plant to grow and reproduce. Each element must be present within a concentration range for optimal plant growth. If the concentration of an essential element in the root zone is too low, a nutrient deficiency occurs, which hurts plant growth. Micronutrients boron (B), manganese (Mn), zinc (Zn), copper (Cu) and iron (Fe), and secondary nutrients calcium (Ca), magnesium (Mg) and sulfur (S) are just as important to plants as macronutrients nitrogen (N), phosphorous (P) and potassium (K). They differ only in the total amounts taken into the plant. Environmental stresses such as cool temperatures, extremely dry soils and water-logged soils can result in reduced uptake and leaching of certain nutrients (N, S and B). In the spring of 2016, we collected soil samples from many of our research and agronomy plots across the U.S. and Canada, around the time of planting. This allowed us to see what our crops really had available at the start of the season. Knowing the nutrient availability at planting provides the opportunity to make a more informed decision on potential in-season fertility applications. As a result of our soil testing program, we noticed that many fields would benefit from the addition of several micronutrients, particularly S (67% of soil samples rated as low), B (91% of samples rated as low to very low) and Mg (48% of samples rated as low), which should come as no surprise given the rainfall events of last spring and their inherent leaching characteristics. Remember, that nitrate-N, S and B can leach as much as 5 inches in a silty clay loam soil. So, in planning for 2017, how do we maximize the yield potential of a grower’s field, knowing that we potentially have low to very low levels of S, B and Mg? The first step will be to conduct a soil test and/or an in-season tissue test. This could be the difference between making a profit or not. Now is the time to make plans for addressing macro and micronutrient deficiencies, which can be easily corrected prior to planting, or with in-season applications. Plus, don’t forget to apply lime as need to adjust pH levels. Finally, be sure to check with your local supplier for tank-mix compatibility of micronutrient products with herbicide and fungicide applications.

How Sulfur, Boron and Manganese Affect Corn and Soybeans

SyngentaAgronomy — Mon, 20 Feb 2017 14:00:08 +0000

We previously talked about how soil fertility is the foundation of all crop production. We also talked about how there are 16 essential elements that are needed by every plant to grow and reproduce, and how each element must be present within a concentration range for optimal plant growth. During our 2016 soil testing program, we found sulfur (S), boron (B) and manganese (Mg) were particularly low in fields. Low S, B and Mg can have a detrimental effect on crops. Let’s take a look at the key plant functions of S, B and Mg: Sulfur (secondary nutrient):

Needed for the conversion of nitrate into organic nitrogen and for protein synthesis.

Boron (micronutrient):

Needed for cell division (i.e. growth), cell wall synthesis and pollen germination.

Manganese (micronutrient):

Important for photosynthesis, nitrate assimilation and iron metabolism.

Let’s take a deeper dive into how deficiencies of S, B and Mg affect corn and soybeans: Sulfur:

Corn: Stunted, spindly plants with light green color. Upper leaves show light green color. Interveinal yellowing or striping of leaves.
Soybeans: New leaves remain pale yellow-green several days, then turn normal green.
Conditions favoring deficiency: Acid and sandy soils that are low in organic matter. Wet and cool soils.

Boron:

Corn: Light green-colored leaves. Slight yellowish stripe on upper leaves.
Soybeans: Interveinal yellowing of upper leaves and stunting. Interveinal yellowing of whole plant.
Conditions favoring deficiency: High soil pH and or organic matter. Depressed areas in fields. Organic sands, peats and mucks.

Manganese:

Corn: Light green-colored leaves. Slight yellowish stripe on upper leaves.
Soybeans: Interveinal yellowing of upper leaves and stunting. Interveinal yellowing of whole plant.
Conditions favoring deficiency: High soil pH and or organic matter. Depressed areas in fields. Organic sands, peats and mucks.

Managing micronutrients is essential for optimal plant growth.

Soil Fertility and Higher Alfalfa Yields

SyngentaAgronomy — Tue, 21 Feb 2017 15:46:57 +0000

Soil fertility fulfills the basic need of a plant – it’s the foundation of all crop production. A crop’s success is largely dependent on vital crop nutrients, such as boron, manganese, zinc, copper, iron, calcium, magnesium, sulfur, nitrogen, phosphorous and potassium. In relatively large amounts, the soil supplies important macronutrients including nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. According to Purdue University, to keeps plants healthy and give them the best chance to compete against insects, diseases and other stresses, a balance of these nutrients is essential. The proper amount of potassium is critical for growth and development, particularly for alfalfa. Potassium fosters higher-yielding and higher-quality alfalfa crops, helping maximize performance and profitability. Potassium also:

Helps regulates enzymatic processes in the plant.
Enhances root development and tolerance to temperature extremes.
Improves drought tolerance.
Minimizes susceptibility to disease.

Consider the plant’s needs before fertilizing: Be sure to test the soil for potassium levels and fertilize accordingly. Adequate nutrition maintains crop vigor and allows plants to better cope with stresses. Proper levels of nitrogen, phosphorus, sulfur and potassium help ensure high yields of quality forage, ultimately helping you grow more alfalfa.

What Does Herbicide Resistance Mean for Wheat?

SyngentaAgronomy — Wed, 22 Feb 2017 20:16:42 +0000

Weeds infest wheat fields, compete with crops and can impact yield and crop quality. Growers turn to herbicides to minimize these threats and to protect their wheat. But sometimes, even when everything has seemingly been done to protect wheat fields, growers still find areas where weeds have not been controlled. This could potentially mean a larger issue is developing: herbicide resistance. What is Herbicide Resistance? According to North Dakota State University, herbicide resistance occurs with repeated use of a specific herbicide or a combination of herbicides in an effort to control a population of weeds that contain some plants with resistant genes. According to The International Survey of Herbicide Resistant Weeds, there are 13 herbicide-resistant broadleaf and grass weed species found today in U.S. wheat crops. In particular, wheat growers have observed widespread occurrences of herbicide-resistant kochia and wild oat. Types of Resistance There are 2 broad categories of herbicide resistance – target site and metabolic. Target site resistance is more common and occurs when the weed population has changed and will no longer allow the herbicide to attach to the target site, making the chemical ineffective regardless of the rate used. Target site resistance is specific to a particular site of action, and one plant can carry multiple resistances. For example, a wild oat plant that has developed Group 1 target site resistance can also develop Group 2 target site resistance. Metabolic resistance occurs when the plant produces an enzyme that breaks down the chemical before it can kill the weed. When products are used below label rates, the risk of developing metabolic resistance will increase. For example, some ryegrass can be resistant to ACCase, ALS and photosystem II inhibitors. It’s extremely important to develop a management program to stay ahead of resistance. Always apply herbicides at the full, labeled rate and at the correct growth stage. This ensures the most effective control. Additionally, sound resistance management practices help to keep resistance at bay while maintaining yields and minimizing costs.

Maximizing Yields in a Soybean Surge

SyngentaAgronomy — Thu, 23 Feb 2017 15:43:22 +0000

Continued low corn prices are causing many growers to plant more soybeans this season. While a potentially profitable transition, Syngenta agronomists are reminding growers to adjust their management plans accordingly – whether they’re rotating their fields from corn to soybeans, or planting continuous soybean acres. If you’re rotating fields from corn to soybeans:

Select the right varieties: As growers are making last-minute seed decisions, they should be selective about which varieties they plant in which fields. The ability to properly match varieties to field conditions can make a difference all season long.
Start from the ground up: Paying attention to the soil can pay off. Use a soybean inoculant to increase the presence of soil bacteria rhizobia, which can help produce more nodulation and increase yield potential. Fields that have gone long periods without soybeans or that have non-optimal soil pH are often ideal candidates for applying a soybean inoculant.

If you’re planting continuous soybean acres:

Switch varieties from year to year: It’s important for growers to avoid planting the same soybean variety in the same field multiple years in a row. Ignore this recommendation, and growers run the risk of developing disease resistance in their fields.
Seek out varieties with strong genetics: Soybean-on-soybean fields are much more susceptible to diseases and pests such as Phytophthora root rot, Sclerotinia white mold and soybean cyst nematodes (SCN). Selecting a soybean variety with strong disease tolerance and resistance to SCN can help maximize yield potential.

California: Rain Brings Good Spirits and Root Rot Fears

SyngentaAgronomy — Fri, 24 Feb 2017 16:08:13 +0000

CALIFORNIA -- So far this year, Mother Nature has been relentless. Storms across California have dropped record amounts of precipitation on many tree nut, citrus and stone fruit acres. And because California soils are naturally infested with various species of Phytophthora, which thrive in these conditions, we’re looking at a high-risk Phytophthora season for tree nuts, citrus and stone fruit. Here are 5 situations where Phytophthora infection is most likely to occur, and the factors that make it such a devastating pathogen in permanent crops:

Wet weather in the spring. Major root flushes and leaf growth occur before and during spring bloom. Wet weather during this time can increase the activity of Phytophthora.
Saturated soils and/or standing water. This creates the perfect scenario for infection to occur and also limits needed oxygen within the root zone.
Good land practices. Years of drought may lend some to think root rot is not possible, but pulse irrigation, salty well water and micro irrigation magnify the issue even in summer or dry winters – often this can make it worse than times of ample surface water.
Permanent crops. In permanent crops, we have no ability to replant or correct mistakes that lead to root rot, so disease impact is much greater than in crops like tomatoes or vegetables. This also means permanent crop growers can deal with the devastating effects of root rot for years to come, especially if it is overlooked for some time.
Micro irrigation vs. flood irrigation. Let’s talk about this a little further. The movement to micro irrigation has made us very efficient in water use, but it has created a perfect scenario for root rot to flourish. Let’s compare:
- With flood irrigation, we irrigate with large amounts of water and then come back 2 or 3 weeks later with more water. This allows the soil to dry down, and free standing water is not present on a continual basis.
- With micro irrigation, we apply small amounts of water weekly with an irrigation often happening over 3 or 4 days. This means that every week we have water running for 3 or 4 days at a time, thus keeping the top 1 foot of soil (where 90% of the roots are) in a state of saturation. This creates perfect conditions for root rot to occur. We’ve become more efficient, but have brought Phytophthora back to the front line of damaging root health.

What can you do to prevent Phytophthora? Because strong, healthy root systems are essential to overall tree health and productivity, it’s important that growers establish an aggressive integrated management system for Phytophthora that includes:

Cultural practices such as providing favorable soil conditions, proper irrigation, using certified disease-free nursey stock and preventing soil/water movement from infested areas
Soil sampling and testing
Soil-applied fungicide during root flush (near bud break/leaf emergence) in the spring and fall

Ridomil Gold® SL fungicide offers long-lasting disease protection against crown rot, collar rot and root rot caused by several Phytophthora species. According to research results from a combined effort of both Dr. Jim Adaskaveg at the University of California Riverside and Syngenta, trees showed larger root mass, tree weight and tree diameter when using Ridomil Gold SL in a Phytophthora management program. Additionally, the Soil Pathogen Assessment (SPA) program from Syngenta helps make soil sampling easy and efficient.

Ten Tips to Combat Herbicide Resistance in Wheat

SyngentaAgronomy — Wed, 01 Mar 2017 14:00:31 +0000

We previously talked about what herbicide resistance means for wheat growers. Now let’s dive into how to approach herbicide resistance. Growers who wait for resistant weed populations to appear can expect herbicide resistance to quickly spread across an entire field. By employing comprehensive management techniques early and continuing them throughout the season, growers can fight the onset of resistance. This will help ensure quality, productive wheat fields with high yield potential at harvest. Tips to Combat Resistance:

Start with clean fields and apply a burndown herbicide to help control emerged weeds before planting.
Plant rotation crops to extend the range of available herbicides and agronomic practices.
Scout fields early and often to correctly identify weeds and select a product that addresses each field’s specific weed spectrum.
Employ multiple modes of action by using a tank mix at each application during the growing season. This will reduce the selection pressure caused by using a single mode of action.
Keep fields clean by using residual herbicides so young wheat plants can absorb sun, water and nutrients without competition from weeds.
Apply herbicides at full, labeled rates and at the correct growth stage for effective weed control.
Use effective adjuvants to improve herbicide efficacy.
Closely monitor problem fields, identifying difficult-to-control weed species and dense weed populations.
Clean equipment as machinery can easily spread seed from one field to another.
Evaluate weed management results at the end of each harvest to improve weed control for the next season.

Part 1: More Powerful Weed Control, More Often

SyngentaAgronomy — Mon, 27 Feb 2017 15:05:08 +0000

As weed resistance expands, growers are looking for solutions to deliver control of their toughest weeds and achieve high yields. Weed control starts with effective modes of action. And powerful weed control leads to high yields. To be effective, herbicides must deliver consistent, powerful control against tough weeds. Premix herbicides with 1 or 2 modes of action can lose effectiveness if weeds become resistant to a herbicide. As resistance develops to 1 mode of action in a premix, greater pressure is put on other modes of action to deliver effective control. Multiple effective modes of action are needed to control the toughest weeds in corn. With more effective modes of action, it is more difficult for weeds to develop resistance against an herbicide. A 2016 Syngenta trial highlights the benefits that multiple effective modes of action have on controlling tough weeds. Acuron® corn herbicide, SureStart® corn herbicide and their individual active ingredients were sprayed pre-emergence on 4-inch pots that were seeded with Palmer amaranth. Similar trials have been conducted to compare Acuron to Corvus® herbicide and Acuron to Verdict® herbicide. The results showed Acuron, with more modes of action, had more effective control, compared to other herbicides. Acuron outperforms competitor herbicides by providing more effective modes of action, longer residual control, greater application flexibility and more power, more often against tough broadleaf weeds.

Part 2: Greater Weed Control, Greater Yields

SyngentaAgronomy — Tue, 28 Feb 2017 14:00:49 +0000

In part 1, we discussed how more powerful control against tough weeds comes with more effective modes of action. Herbicides with more effective modes of action outperform other herbicides by helping growers achieve higher yields. Broadleaf weeds are a yield-robbing pest across the Corn Belt, and if left uncontrolled, broadleaf weeds can cut yields up to 50%*. Weeds can compete with corn for vital nutrients and can cause significant yield loss. Recent trials show how effective weed control leads to higher yields. Trial results from Ohio State University and Purdue University show that Acuron® corn herbicide, containing 4 active ingredients and 3 effective modes of action, delivers an average yield increase of 50 bu/A compared to Verdict® herbicide + AAtrex® 4L herbicide, and an average increase of 29 bu/A compared to Corvus® herbicide + AAtrex 4L. By providing more powerful weed control, Acuron outperforms competitors by delivering greater yields.

Warm Weather in the South Sets Stage for Diseases

SyngentaAgronomy — Mon, 27 Feb 2017 19:27:32 +0000

Warm weather helps diseases thrive, and with the mild winter in the south, growers should be prepared for significant disease pressure this season. Being proactive will be key. How can you protect your crops from diseases? Fungicides can play an important role in protecting your crop by helping to create a protective layer against damaging fungi. Be sure to use an integrated management program that combines:

Cultural practices
Varieties with genetic resistance
Fungicides

Trivapro® fungicide combines 3 modes of action for the hardest-working, longest-lasting, broad-spectrum disease control on the market with preventive and curative disease control that greatly minimizes the potential for resistance development.

Frost Risk for Almond Growers

SyngentaAgronomy — Fri, 03 Mar 2017 14:00:39 +0000

With temperatures forecasted to drop, there is a frost risk for almonds growers. Regardless of whether this forecast becomes reality or not, it’s important to always be ready to prevent frost damage. According to the University of California Cooperative Extension, there are a few things to keep in mind:

Types of frost.There are 2 major types of frost events that occur throughout California – advection frost and radiation frosts.
Almond susceptibility to frost.The further the tree advances out of dormancy, the more sensitive to frost it becomes.
Frost damage prevention. Growers can manage soil moisture and ground cover to help reduce frost damage from a radiation frost event. You can utilize active frost protection by introducing air movement or heat. The use of micro sprinklers and solid-set sprinklers also provide frost protection.

Additionally, the University of California Cooperative Extension recommends mowing cover crops or residual vegetation to allow radiant heat from the soil to move into the canopy, and using a sprinkler system to apply water to warm the orchard.

Kentucky: Freezing Temperatures and Winter Wheat Damage

SyngentaAgronomy — Wed, 08 Mar 2017 14:00:22 +0000

KENTUCKY – Recently, we’ve experience freezing temperatures. Depending on which growth stage your winter wheat is currently at, this may cause damage to the plant. According to the University of Kentucky Extension, here are tips to assess freeze damage:

Wait until high temperatures are at least 40°F for 5 to 7 days.

With high temperatures inthe forecase, assessing freeze damage soon will likely provide an accurate estimate.

Scout fields and look for yellow, chlorotic growing points/limp leaves.

There will likely be yellow leaf tips, but as long as the growing point is not affected, therewill be minimal to no damage.

Look out for heaving.

Heaving is another concern for wheat stands and yield potential. The extreme temperature changes we've been this winter could push wheat plantsout of the soil. This can result in reduced stands and ultimately affect yield if heaving occurs on a large percentage of the field.

Expect These Top Soybean Pests in 2017

SyngentaAgronomy — Thu, 09 Mar 2017 14:00:38 +0000

With record-shattering temperatures and the warmest February the South and Midwest have experienced in years, expect a season full of yield-robbing pests. Kelly Estes, agricultural pest survey coordinator with the University of Illinois, in a recent Prairie Farmer article, named top pests to pay extra attention to going into the 2017 growing season. One pest to be scouting for early on is the brown marmorated stink bug (BMSB), which could wreak havoc on soybeans. With mild winter temperatures, overwintering BMSB populations could be high. Estes also mentions to be on the lookout for Japanese beetles. They typically cause most harm beginning in June, but growers should be scouting before they reach an economic threshold. Purdue University warns that Japanese beetles are usually not uniformly distributed throughout a field, so sweeping multiple areas is crucial to an accurate diagnosis. To prevent BMSB and Japanese beetles from injuring soybeans early on, we recommending using Endigo^® ZC insecticide to provide quick knockdown and extended residual control. Using an insecticide treatment when pests reach economic threshold is an essential component of maximizing yield potential to grow more soybeans.

Managing Phytophthora Blight in Peppers

SyngentaAgronomy — Fri, 10 Mar 2017 16:20:54 +0000

According to Penn State University Extension, Phytophthora blight may be the worst disease vegetable growers can encounter. It can be bad enough that some growers consider selling their Phytophthora infested farms and moving to a ‘clean’ farm. When this disease sneaks into your fields, it settles in with the intentions of establishing a permanent home. According to the same article, Phytophthora blight can live in the soil for 7 or more years by setting up its own self-sustaining system underground. When the moisture begins to build, Phytophthora attacks and the decaying process starts in the stem at the ground level of the plant. If Phytophthora blight invades your fields, you’ll first notice wilting pepper plants and soon see the fruit that is touching the ground begin to rot. As the disease spreads through the stems and into the fruit, white mold will begin to build around the rotting areas of the fruit. Phytophthora can easily spread through water and soil. Here are some key ways to avoid the spread of the disease:

Clean farm equipment used in another before using in your field
Closely manage your irrigation system as water from an infected pond can infect your field
Dispose of infected fruit properly, away from your field
Use proper soil management practices
Use tolerant varieties

Syngenta offers varieties with genetic resistance to Phytophthora, including Paladin and Intruder. Both varieties are great fits for the eastern U.S., and produce high-yielding, large fruit of consistent quality. Soil application of a fungicide with activity on Phytophthora, including Orondis® Ridomil Gold® SL fungicide, can also help manage the disease to ensure uniform crop establishment. Fruit rot control may be enhanced if soil application of Orondis Ridomil Gold SL is followed by a foliar program.

Arkansas Rice: Phosphorous, Potassium and Lime Applications

SyngentaAgronomy — Tue, 14 Mar 2017 14:00:41 +0000

Although we’re still weeks away from rice being planted, we should start thinking about timing of phosphorous (P), potassium (K) and lime applications now. According to the University of Arkansas Research & Extension, properly timed application is key. What’s the general rule for timing? The closer to rice planting P and K are applied, the less likely these nutrients will be fixed or lost, which maximizes their direct benefit to the rice crop. Apply too early, however, and the University of Arkansas Research & Extension warns that the chances of P being held in forms not readily available to the plant and the likelihood of K leaching increases. Lime applications are usually not recommended going into planting rice, however, assess the pH levels in your fields to confirm. What can you do to determine if and when you should apply P, K and lime? The answer is soil testing.

Corn and Soybeans: Four Tips for Successful Planting

SyngentaAgronomy — Mon, 06 Mar 2017 14:48:17 +0000

It may not be spring just yet, but it won’t be long before it’s time to kick off the 2017 corn and soybean growing season. Maximizing yield potential begins at planting, so here are some things to keep in mind in the next few weeks:

Start with the right genetics. Although many growers have already selected their hybrids and varieties for the year, some are still weighing their options. Growers are advised to consider the unique needs of each of their fields and work with a local seed expert to identify the hybrids and varieties most likely to succeed where they farm. Golden Harvest® offers a wide-ranging portfolio with agronomic solutions to maximize yield on each field.
Adjust planter settings as needed. Growers should make adjustments to their planter between fields as needed, particularly if planting seeds that range in size.
Plant at the right depth. Depending on soil moisture and soil type, agronomists typically advise that growers plant corn hybrids at least 1.5” deep and soybean varieties 1” to 1.5” deep. Planting seeds too shallow can cause issues with secondary root development further down the road, which can ultimately lead to yield loss.
Start planting when the conditions are right – even if it’s not the “right” calendar date. While it may be easy to let the calendar dictate when exactly planting should start, growers shouldn’t begin planting until the conditions are right. When planting corn and/or soybeans, soil temperatures should be at or near 50 degrees with warmer weather on the way, and the soil should be dry enough to prevent problems with unclosed seed slots.

Pest Alert: Rust Strikes Wheat in Multiple Regions

SyngentaAgronomy — Mon, 13 Mar 2017 13:00:29 +0000

Wheat growers across the U.S. need to be prepared for stripe rust this season. Already having been identified in multiple regions, it’s important to be on the lookout for this disease, especially as temperatures get warmer. According to the University of Wisconsin, wheat growers should be prepared for continued stripe rust pressure throughout the Midwest this season. Since this disease has already been confirmed in Nebraska in late January, it’s likely that stripe rust will continue to be an issue in the Midwest, among other regions. According to the University of Delaware, stripe rust was also confirmed in Robeson County, NC, which increases the chances of pathogens spreading throughout the South, as well. In addition to stripe rust, Bob Hunger, Extension Wheat Pathologist at Oklahoma State University explains that leaf rust overwintered in Oklahoma wheat that was planted in mid-September, which has evidently spread to some of the newer leaves. It’s important to get ahead of pests, especially with conditions as unpredictable as they’ve been in much of the country. It’s also best to start early and scout at multiple stages of the growing season. When scouting for rust, look for bright yellow pustules on the flag leaves. If you find rust in your wheat, we recommend applying Trivapro^® fungicide, which provides long-lasting control of stripe rust and leaf rust in wheat. One application of Trivapro delivers stronger residual control compared to competitive 1-pass and 2-pass programs. Maintain consistent scouting practices throughout the season, and increase the frequency as needed during times of high pest pressure. It’s much easier to prevent diseases than try to control them once they are already present in the field.

Part 1: 2017 Plan of Action: Manage Resistance with Multiple MOA’s

SyngentaAgronomy — Wed, 15 Mar 2017 16:38:52 +0000

Weed resistance is expanding. According to market research*, more than 46% of farmers reported weed resistance to 1 herbicide group while more than 20% of growers reported weed resistance to 2 herbicide groups. Not only is resistance to several herbicide groups expanding geographically, concern about resistance to a few key herbicide groups is also increasing. The study shows that growers are more concerned about resistance to the following herbicides:

Group 2 (ALS inhibitors)
Group 4 (synthetic auxins)
Group 9 (glyphosate)
Group 27 (HPPD inhibitors)

Resistance to Group 14 (PPO inhibitors) is also a growing concern across the Midwest. It’s common to be concerned about resistance expanding when it’s already confirmed in the field. But growers without reported resistance are also concerned about resistance spreading. The study shows from 2014 to 2016, concern about Group 2 resistant weeds increased from about 15% to almost 19% of growers without Group 2 resistance. From choosing the right inputs to determining crop rotations, staying ahead of resistant weeds can feel challenging. With the number of resistant weeds growing, it’s driving a need for more powerful and effective management strategies to defeat these tough resistant weeds. The right weed management strategy can put growers’ minds at ease. Finding the best management strategy starts with understanding problem weeds in the field and incorporating good agronomic practices, such as narrow row spacing and increased plant population. We also recommend using herbicides with multiple effective modes of action early in the season to manage weed resistance. Herbicides like Acuron® and Acuron® Flexi for corn and BroadAxe® XC and Boundary® 6.5 EC for soybeans contain multiple effective modes of action and active ingredients that work together to control the toughest weeds before they emerge.

Ohio: Increased Stink Bug Scouting Needed in Soybeans

SyngentaAgronomy — Thu, 16 Mar 2017 18:15:00 +0000

OHIO - Dr. Kelley Tilmon, pest specialist at The Ohio State University Extension, is calling for increased stink bug scouting in soybean fields this season. In her recent webinar, “Insect Trends in 2016” Tilmon says the extension received an average number of stink bug reports during the 2016 season. However, at harvest, they began receiving an abundance of stink bug damaged soybean samples. Tilmon attributes this issue to ineffective scouting. With record-breaking mild temperatures this winter, overwintering stink bug populations could be high. Tilmon suggests scouting for stink bugs beginning at flowering and through pod-fill (R1-R6). Since stink bugs typically begin feeding on the outskirts of the field, she recommends starting at the edges and if stink bugs are found, working your way into the middle of the field. Tilmon defines the economic threshold as two or more stink bugs per 10 sweeps. Should stink bugs reach this threshold, we recommending using Endigo^® ZC insecticide to provide quick knockdown and extended residual control. Staying on top of scouting efforts and being prepared to use the right insecticide treatment before stink bug infestations get too large is an essential component of maximizing yield potential to grow more soybeans.

Texas Sorghum: Watch for Early-season Sugarcane Aphid

SyngentaAgronomy — Tue, 21 Mar 2017 13:00:54 +0000

TEXAS -- Sugarcane aphids are likely to return to Texas sorghum fields this season. To help you prepare for this pest, Texas A&M AgriLife Extension offers these management tips:

Let beneficial insects do some of the work. The abundance of beneficial insects early in the season this year will be important in protecting sorghum by preventing aphid movement from Johnsongrass to sorghum fields.
Plant early for less aphid pressure. The farther along sorghum plants are by the time aphids arrive, the better chance they have of surviving any damage. Younger plants are more susceptible to aphid damage.
Utilize seed treatments. Texas A&M AgriLife Extension recommends that neonicotinoid seed treatments be used on all sorghum.
Choose resistant or tolerant hybrids. There is a significant economic benefit to using resistant hybrids even though they still need to be sprayed at the normal threshold.

Part 2: Stay Ahead of Resistant Weeds in the Central Plains

SyngentaAgronomy — Fri, 17 Mar 2017 20:16:08 +0000

Weed resistance is expanding across the Midwest. When the same herbicides are overused, weeds become resistant to the herbicide, thus the herbicide loses effectiveness. It’s no surprise that farmers’ concern about resistance is also increasing. Experts recommend that using an herbicide with multiple effective modes of action is a powerful way to manage resistant weeds. Growers in the Central Plains shared why they use Acuron® corn herbicide to manage weed resistance in their fields. After failed attempts controlling marestail, pigweed and morningglory, Andy Zwick, a grower from Sterling, KS, was looking for a new solution for his tough glyphosate-resistant weeds. He found that Acuron provided the flexibility and control he was looking for. A lot of glyphosate-resistant weeds have come about in the last 6 years, and Zwick has had to use more modes of action to keep these weeds in check. Acuron took control of his glyphosate-resistant marestail. Glenn Beller from Lindsay, NE, also explains why he used Acuron to manage resistant weeds. When reflecting on fight against weed resistance in 2016, Beller believes it’s no longer a question of if or when resistance weeds will impact corn fields. Instead, it’s a question of how can he manage them? Because resistance continues to be a growing issue, it’s important to be proactive and look for the best solutions. Previously having problems with resistant waterhemp, an application of Acuron helped Glenn tackle his toughest weed.

Southeastern Watermelon Diseases to Watch for in 2017

SyngentaAgronomy — Mon, 20 Mar 2017 22:39:52 +0000

Gummy stem blight is the most common watermelon disease in the Southeast, according to the results of a Clemson University survey shared in a recent Growing Produce article. This disease produces large, target-shaped spots on leaves and cankers on stems of watermelon plants. Often overlooked by growers, powdery mildew is the second most common disease in watermelons. No resistant cultivars of watermelon are available, so fungicides are necessary to control this disease. Powdery mildew can spread quickly under favorable conditions, causing symptoms to appear within three days of infection. Clemson University Cooperative Extension advises that systematic fungicides are necessary to control these major diseases. This growing season, Syngenta recommends Orondis® Opti and Aprovia® Top fungicides as components of a season-long disease control program to protect crops and help maximize marketable yield.

Part 3: How to Stay Ahead of Resistant Weeds in the Midwest

SyngentaAgronomy — Wed, 22 Mar 2017 17:15:34 +0000

Weed resistance management is an important consideration when prepping for the growing season. Multiple modes of action used to be enough. But herbicides lose effectiveness when weeds become resistant to a mode of action in an herbicide, which puts more stress on the other modes of action in an herbicide to deliver effective control. Experts recommend that using an herbicide with multiple effective modes of action is a powerful way to manage resistant weeds. Some growers in the Midwest shared why they use Acuron® corn herbicide to manage weed resistance in their fields. After a disappointing 2015 season in his field, Rob DeFauw, a grower in Genesco, IL, wanted to try something new. So to help tackle his toughest weeds, giant ragweed and marestail, he decided to try Acuron in 2016. DeFauw knew that multiple effective modes of action were needed to control his tough weeds. And with 3 modes of action and 4 active ingredients, DeFauw was confident Acuron would get him ahead of the curve with weed management practices. Josh Miller, a grower from Tamms, IL, says that weed pressures have taken off in previous years. And with different types of resistance out there, weeds are getting harder and harder to defeat. To keep his weeds in check, he used Acuron to really help with the weed management issue in his fields. Better resistant management is key to a successful season.

Increased Leafspot Risk for Sugarbeet Growers in 2017

SyngentaAgronomy — Thu, 23 Mar 2017 15:00:56 +0000

MICHIGAN – 2016 was a rough year for sugarbeet growers, with uncontrollable factors such as weather and disease causing the lowest sugar content since 1986. Drought early in the season and extended warm weather in fall caused decreases in overall sugar content as sugarbeets continued to grow instead of store sugar. In addition, the late rain in August caused the perfect growing grounds for Cercospora, Alternaria and bacterial leafspot. This resulted in early defoliation of leaves and reduced tonnage. As the 2017 growing season begins, Michigan State University Extension reminds growers that there is an increased risk of leafspot and that they should take preventive measures to prevent leafspot in their sugarbeets. Syngenta recommends a fungicide like Inspire® XT, which has high intrinsic activity to control leafspot and powdery mildew.

Cotton Seed Treatment Considerations for 2017

SyngentaAgronomy — Fri, 24 Mar 2017 14:08:17 +0000

As cotton growers are preparing to plant, proper planning and management strategies are necessary for optimal stand establishment. Poor soil temperatures and moisture levels, as well as heavy insect pressure, will adversely affect plant population, and ultimately crop yield and quality. Scouting cotton in the early stages of development can help identify fields where plants may be under adverse stress. According to the Cotton Grower and entomologists at the Mississippi State University Extension, cotton seed treatments may be more important to utilize in 2017 with the threat of thrips looming. Severe thrips infestations can cause stunting, maturity delays and yield losses. Because the severity of thrips cannot be predicted, insecticide seed treatments and foliar insecticide applications are recommended to reduce the risk of thrips damage. Using a seed treatment like Avicta^® Elite Cotton Plus with Vibrance^® can help protect against early-season diseases, nematodes and difficult insects. An early foliar application of an insecticide with an alternate mode of action, from the neonicotinoid class of insecticides, at the one true leaf stage can also help. A proactive, season-long approach to weed management can help growers keep potential issues in check. With weeds exhibiting resistance to several chemistries, growers need to diversify their programs and include herbicides with different modes of action, like Dual Magnum^® and Caparol^®. Dual Magnum can be used pre-plant surface-applied, pre-plant incorporated or as a pre-emergence application, while Caparol provides foliar knockdown of emerged weeds and residual control of later-germinating weeds for even greater flexibility.

Controlling Late Blight in Potato Crops

SyngentaAgronomy — Tue, 28 Mar 2017 14:47:38 +0000

Potato growers know that preventive planning is a key aspect of protecting potatoes from yield-robbing diseases. With planting underway for some and just on the horizon for others, extension experts remind growers about the importance of starting each season with clean potato seed as a first line of defense against some key potato diseases, including late blight. Under favorable conditions, late blight can destroy a potato crop within a few days. The first symptoms of the disease are small, light to dark green, circular to irregular-shaped water-soaked spots. Lesions usually appear first on the lower leaves of potatoes. A white cottony mildew develops on and around foliar lesions. Late blight thrives under cool, wet weather, and the disease cycle may be interrupted during dry spells, but will progress when damp weather returns. In addition to leaves, stems and petioles, potato tubers are also susceptible to late blight. Syngenta recommends Orondis® Opti, a fungicide that offers reliable control, even under heavy disease pressure. A foliar fungicide that combines two active ingredients, oxathiapiprolin and chlorothalonil, Orondis Opti defends against late blight on potatoes by protecting the crop when it is most actively growing and by helping to maximize marketable yields.

Pest Alert: Root Rot Detected in Western Kansas

SyngentaAgronomy — Tue, 28 Mar 2017 18:48:15 +0000

Several samples of wheat from western Kansas have been infected with common root rot, according to a recent Kansas State early-season outlook for wheat disease report. Common root rot is present at low levels almost every year in Kansas and survives between seasons on crop residues and organic matter in the soil. In most years, the plants have enough healthy roots to compensate for the damage caused by the disease. The disease is caused by a soil-inhabiting fungus that survives as spores in the soil or on infected debris from previous crops. Infections can linger in cereal fields, causing numerous issues including seedling death in extreme cases. It is also commonly misidentified or undiagnosed. Visible symptoms can include:

Elongated brown spots or lesions
Plant breakoff that occurs easily near the ground
Roots of infected seedlings that are rotted and may be covered with white, gray or pink mold

If only part of the root system is involved, the plant does not tiller and sends up only a single stem with a small seed head. When root rot occurs, the plants have brown crowns and lower stems. As they approach maturity, ripening is premature and plants can die prematurely, often having a bleached appearance. Common root rot typically occurs after spells of hot weather following a period of cool weather. It is also most prevalent in fields where wheat is planted following corn. Syngenta recommends a seed treatment like CruiserMaxx® Vibrance Cereals, which helps protect seeds, seedlings and root systems from common root rot. Formulated to boost a crop’s RootingPower by delivering enhanced disease protection that leads to stronger root systems and improved crop performance, it acts as a barrier to protect the root system from the spores in the soil and lowers disease risk. Regularly scout fields to track the presence of common root rot and other diseases in your fields.

You’ve made your corn seed investment. Now what?

SyngentaAgronomy — Wed, 29 Mar 2017 13:52:26 +0000

The list of factors that can impact yield during the season is a long one, which is why it’s critical to begin with as much yield potential as possible. Careful preparation and planning now – before the seed hits the soil – will go a long way toward end-of-season success. With corn planting just around the corner, here are some key things to keep in mind:

Note the genetics. Growers should get to know their hybrids through and through, learning the soil types and other environmental and management conditions in which they’re most likely to thrive.
Map out which soil types are where. This will help decide which hybrids need to go into which fields. Factors such as soil texture, nutrient holding capacity and water-holding capacity can make a big difference in how a hybrid yields. For example, some hybrids thrive in fine soil, while others do better in coarse conditions.
Don’t forget to check drainage and soil pH. Help ensure that each hybrid is planted in an environment where it can succeed by being aware of how each field drains water and what the soil pH levels are.

To further explore how to best map out where your soil types are, watch as Product Development Agronomy Manager Doug Kirkbride demonstrates the differences between the three main soil types, and how that affects hybrid placement.

Defend Nebraska Yields Against Challenging Marestail

SyngentaAgronomy — Thu, 30 Mar 2017 19:19:33 +0000

While the Nebraska heartlands may be known as “The Good Life”, a pesky weed invasion has been making life more difficult for the state’s growers. Marestail, also known as horseweed or Canada fleabane, has thrived in no-till crop production systems over the last 20 years. A single marestail plant can produce up to 200,000 seeds, which can be easily dispersed, covering entire fields. To make matters worse, marestail is the first glyphosate-resistant weed reported in the U.S. and has been spotted in 25 states, including Nebraska. Therefore, implementing a proactive weed management plan is vital to protect yields. In a recent Nebraska study, Acuron® herbicide was put to the test against this challenging weed. In pre-emergence trials, Acuron knocked down marestail, producing more than 90% control. Post-emergence applications also provided about 70-85% control.

Sorghum, a Rotation Option for Cotton Growers in 2017

SyngentaAgronomy — Fri, 31 Mar 2017 20:33:06 +0000

Cotton growers considering new crop rotation options may want to consider sorghum. Sorghum residue helps minimize evaporation from soil and protects cotton seedlings from wind and sand-blasting. According to a recent article in Cotton Grower, Texas A&M AgriLife research has shown that cotton yields increased when grown in rotation with sorghum. During sorghum rotations, keep an eye out for the sugarcane aphid. Vigilant scouting is important and scouting once a week is recommended, as long as no aphids are identified. In addition, Syngenta recommends using tools like resistant varieties and seed treatments like CruiserMaxx® Sorghum, which can help growers manage this pest. The United Sorghum Checkoff Program recently released a video series on sugarcane aphid management for 2017. The videos summarize best practices for steps growers should take to defend against the sugarcane aphid. For more information, watch the videos on the Sorghum Checkoff YouTube channel.

Plan Ahead for High-Yielding Sugarbeet Crop

SyngentaAgronomy — Mon, 03 Apr 2017 17:59:59 +0000

Mild weather has growers itching to hit the fields and get a jump start on planting. University and extension researchers remind growers to use a cautious approach because of the unpredictability of weather and encourage growers to consider the risks of early planting. It’s also important to know the risks and best practices for late planting, in the event weather takes a turn. According to the Michigan State University Extension, taking advantage of early sugarbeet planting opportunities can pay good dividends when it comes to improving both crop yield and quality. Planting early can increase the length of the growing season and allows the sugarbeet plant to capture more sunlight that is converted and stored as sugar. Early planting will also bolster tonnage and can greatly improve recoverable white sugar per acre. To ensure growers are starting their crop off for a successful season, the most important thing they can do is to plant the right hybrid on the right field. Growers can choose the correct genetic package and seed treatment for each field’s individual needs, including hybrids that provide tolerance to pest issues they have faced in the past, especially if they are in an area with Pythium, Fusarium or Rhizoctonia. In addition, correct planting timing allows seedlings to become established making them less vulnerable to injury from insect pest feeding. Planting early also allows sugarbeet plants to establish healthy tap roots that can get a good start on penetrating deeper into the more moist zones of the soil profile. We’re excited to ring in the early spring planting season and help growers across the country tackle both their most pressing challenges and profit-maximizing opportunities to grow more sugar.

4 Winter Wheat Management Tips

SyngentaAgronomy — Wed, 05 Apr 2017 15:52:09 +0000

With areas of the country experiencing warmer weather earlier than normal, winter wheat is already breaking dormancy. If you are seeing this in your winter wheat fields, here are four areas to pay attention to as green-up continues:

Determine soil nutrients. Nitrogen is a key component to winter wheat. The Michigan State University Extension recommends answering two questions – Can N be delivered to the plant in a timely fashion? And, can opportunities for N loss be reduced without affecting N delivery to the plant? Depending on your response, it may or may not be the right time to apply N.
Look for freeze damage. Even with the warmer spring, there is still a chance for a few cold snaps, which can damage wheat heads and cause deformities. If temperatures fall below 30 degrees, Penn State Extension recommends keeping an eye on fields of wheat where jointing has begun.
Scout fields for disease. Look for common early-season diseases such as stripe rust, fungal leaf spots and powdery mildew.
Use proactive management for wheat diseases. It only takes a small amount of inoculum for a disease to develop and spread under favorable weather conditions. To prevent its spread, be proactive. Syngenta recommends a fungicide like Trivapro®, which delivers excellent, long-lasting disease control against rusts and leaf spot.

Prepare Sugarbeet Fields for a Strong Season

SyngentaAgronomy — Wed, 05 Apr 2017 20:03:09 +0000

While high-quality seed is strongly recommended for sugarbeet growers, seed quality alone may not be enough to ensure solid stand establishment. Growers must properly prepare their seedbed, plant and care for their beets in order to reap a harvest worth bragging about. According to the 2017 Sugarbeet Production Guide from the North Dakota State University, sugarbeets should be planted 1”-1.25” deep for maximum germination and emergence, and seed should be 3”-4” apart in 22” rows if they are to be thinned, or 4.5”-5” apart if planting to stand. While these general guidelines can be followed for most operations, each sugarbeet production region recommends different planting depths, widths and spacing. It is best to check with local extension services or co-op agronomists to determine the best depth and spacing. In addition, growers can visit the Syngenta Sugarbeet Planting Guide seed spacing calculator to determine seed quantity recommendations for nearly any row width. Seed contact with moist soil is also an essential criterion for good stand establishment. Sugarbeets are planted very shallow compared to other crops, so it’s absolutely critical to get them placed into moisture so it can get to the seed. Since the upper inch of the soil can dry out rapidly, good seed-to-soil contact is needed to allow the seed to imbibe water and take up nutrients for a strong start. Selecting quality seed and following best planting practices will certainly help build the foundation of a solid sugarbeet crop. However, to reach full yield potential, growers should consider several other factors to help spur growth and development while protecting plants.

Soybean Planting Tips to Start the Season Right

SyngentaAgronomy — Thu, 06 Apr 2017 22:20:57 +0000

With spring in sight, soybean planting is just around the corner. As growers begin planning for the season, they should consider these tips before getting out into the field:

Plant early: Typically, most soybeans are planted between late April and early May. In a Purdue University study, soybeans that were planted in early May consistently produced higher yields than those planted later, across all regions in Indiana. However, before planting, growers should make sure to check the recommended planting conditions for their area.
Plant in ideal soil conditions: Although planting early is typically the most beneficial, waiting for optimal soil temperature and conditions takes priority to timing. Planting when soils are too wet or too cold can reduce emergence and plant populations, and lead to reduced yields, according to the Iowa State University Extension.
Understand weed pressures: Many weed species have the ability to lay dormant over the winter. It’s important to be prepared with the right management strategies to protect soybeans from weeds from the start. Check out the Resistance Fighter^® program for localized weed resistance management tips.
Plant varieties that are resistant to SCN and SDS: When planting fields with confirmed soybean cyst nematode (SCN) presence or susceptibility to soybean sudden death syndrome (SDS), it’s important to plant varieties that are resistant to both. Growers should keep in mind that this alone is not enough to combat them and should prepare for SCN and SDS by also applying a seed treatment with proven activity on these pests. We recommend applying Clariva^® Complete Beans seed treatment, a combination of separately registered products, which kills SCN season long and reduces the damage from SCN-related diseases, including SDS. The addition of Mertect^® 340-F fungicide can further protect your high-value seed from SDS.

Multi-Herbicide Resistance Research Goes a Long Way

SyngentaAgronomy — Fri, 07 Apr 2017 17:06:51 +0000

An ounce of research is worth a ton of savings when it comes to weed resistance management, especially in a time where every input impacts the bottom line. This season, pigweed poses a serious problem to growers in the Midwest and South due to its easy spread, difficult identification and ability to develop resistance to multiple herbicides. In 2016, the University of Illinois Plant Clinic tested approximately 2,000 waterhemp and Palmer amaranth plants from 593 fields across 10 states. The following 5 states demonstrate the highest percent of waterhemp and/or Palmer amaranth field samples that tested positive for both glyphosate and PPO inhibitor resistance. Additionally, the University of Tennessee reported that 20% of sampled Palmer amaranth in TN showed resistance to PPO inhibitors. The impact of this relatively low figure can be magnified, if the weed’s seed bank is large. Herbicides should effectively control target weeds and help maximize yield potential, rather than potentially failing and letting resistant weeds go to seed. Before choosing an herbicide program that could result in a costly weed control failure, take the Resistance Fighter^® Weed IQ Quiz to test your weed resistance knowledge and boost your chances of outsmarting the weeds this season.

Warm Winter Brings White Mold Risk in Peanuts

SyngentaAgronomy — Mon, 10 Apr 2017 21:36:35 +0000

The subfreezing temperatures typically experienced during winter help act as nature’s defense against lurking diseases from one growing season to the next, but this year’s unusually warm winter has created prime conditions for disease pathogens and nematodes to thrive. In Peanut Grower, the University of Georgia Cooperative Extension urges growers to plan for the effects of a warm winter when determining peanut disease management programs for 2017. Warm weather can spark outbreaks of white mold early in the season. This disease threatens peanuts along the soil line and near the soil surface, leading to the death of limbs and crown, which results in the destruction of pegs and pods. Extreme cold usually kills these pathogens in the winter, but sustained warm weather has allowed them to build up in fields over time. Take extra precautions early in the growing season to prevent costly, yield-robbing infections of white mold. Syngenta recommends Elatus® fungicide for excellent white mold control in peanuts.

Prevent Mid-South Corn Yield Loss with Weed Control

SyngentaAgronomy — Tue, 11 Apr 2017 20:16:52 +0000

According to the University of Arkansas, weeds will rob corn yield regardless of how thick the infestation. Losses can range from 10-15% for light weed infestations to 50% for heavy infestations. For example, in a field that would normally produce a 180 bu/A yield, weed infestation could reduce yield by 18-90 bu/A. Weed management in corn across the Mid-South is critical. Researchers regard the first 6 weeks after planting as the most important for weed control. During this time, they speculate that corn plants may be able to detect the presence of weeds and alter their growth patterns to compensate. The next 3 weeks is another crucial time as this is when ear size is determined. In addition, controlling weeds early enables a corn plant to better compete with later emerging weeds. For optimum, season-long weed control, we recommend a two-pass program of Acuron^® herbicide pre-emergence followed by Halex^® GT post-emergence. The photos below from 2016 Syngenta trials at the Agri-Center in Memphis, TN, demonstrate the season-long control of treatments including Acuron and Halex GT. These bare-ground plots planted with weeds show a dramatic difference in weed control. Pre-emergence herbicides were applied on April 23 with post-emergence herbicides applied on May 28.

Resistant Cucurbit Varieties are Key to Anthracnose Management

SyngentaAgronomy — Wed, 12 Apr 2017 21:07:33 +0000

When it comes to destructive diseases to watch out for in cucurbit crops, growers should have Anthracnose at the top of their list, particularly during warm, moist seasons. Caused by the fungus Colletotrichum lagenarium, Anthracnose can inflict significant damage on watermelon crops. According to a University of Florida Extension article written for Growing Produce, all-above ground plants can be infected by Anthracnose. On watermelon foliage, symptoms begin as water-soaked leaf lesions that progress to dark brown or black spots. On fruit, circular, black, sunken cankers develop and may measure ¼”-½” in diameter, and up to ¼” in depth. Cankers lined with moisture will present a gelatinous mass of salmon-colored spores that cover the black center of the lesion. This visually striking symptom is unique to Anthracnose and can lead to significant reductions in marketable yield. Syngenta offers several seedless watermelon varieties with intermediate resistance to Anthracnose, including: Fascination

Attractive red, firm flesh
Excellent yield potential
Improved disease resistance

Knock Out Early-Season Weed Competition

SyngentaAgronomy — Thu, 13 Apr 2017 17:12:33 +0000

March’s above-average temperatures in the Midwest will continue into spring and early summer, according to the NOAA Climate Prediction Center. Summer annual weeds, such as kochia, giant ragweed, common ragweed and common lambsquarters, will likely take advantage of these favorable weather conditions and emerge earlier than normal. The Iowa State University Extension recommends that growers minimize the risk of early-season weed competition by using a pre-emergence residual herbicide to reduce the number of weeds and delay their emergence in relation to the crop. A timely post-emergence herbicide application before critical periods can help further protect crops from weed competition and yield loss. When determining an herbicide program for these early-emerging problem weeds, ensure it includes multiple effective modes of action. According to the United Soybean Board, kochia and common ragweed have shown resistance to four different modes of action while giant ragweed and common lambsquarters have shown resistance to two different modes of action. Take the Resistance Fighter^® Weed IQ Quiz to help boost your weed resistance knowledge and better prepare your fields for resistant weeds this season.

Manage Giant Ragweed Resistance in Corn

SyngentaAgronomy — Thu, 13 Apr 2017 22:07:53 +0000

West Bend, IA: Acuron 3 qt/A Pre (left) vs. neighbor’s field with heavy giant ragweed presence (right) Giant ragweed is a formidable, tough weed. One giant ragweed can grow up to 20’ tall, quickly diminishing yield potential by preventing sunlight from reaching shorter corn plants and consuming valuable nutrients for its own growth. Season-long competition from several giant ragweed plants has been shown to reduce corn yields by up to 13%* and thick groupings of the weed have been known to stop combines in their tracks, costing growers additional time and money. Despite its reputation as a tough weed and the spread of resistant populations, giant ragweed is manageable with a “start clean, stay clean” approach to weed control:

Start clean with tillage and/or a burndown herbicide application.
- Starting the season with clean fields allows corn to start strong and maximizes its potential.
Apply a pre-emergence residual herbicide like Acuron® or Acuron Flexi with multiple, effective modes of action at the full-labeled rate.
- Acuron and Acuron Flexi contain bicyclopyrone, a HPPD inhibitor shown to provide a high level of consistent control on tough weeds like giant ragweed, even resistant biotypes.

Cut-rate applications may not provide optimal weed control and put more pressure on post-emergence herbicide applications.
In a two-pass system, a foundation rate of Acuron or Acuron Flexi should be applied pre-emerge and then followed with the remaining rate post-emergence.

Scout corn fields often throughout the season and control escapes to prevent giant ragweed from going to seed.

Don’t Overlook These Corn and Soybean Weeds

SyngentaAgronomy — Fri, 14 Apr 2017 15:15:14 +0000

Weeds have the ability to lay dormant in corn and soybean fields during winter months. With the aggressive weed pressure seen in 2016, it’s especially important to prepare for the 2017 season with a plan of action in place. Growers can expect the following weeds to be problematic again this season:

Palmer amaranth: This weed produces 10,000 to 100,000 seeds per plant and can grow up to 8 feet tall. It thrives in no-tillage systems because it germinates close to the soil. Growing up to 3” per day, it easily overtakes a crop due to its rapid growth. When scouting, look for hairless, diamond-shaped leaves with stems as long as or longer than the leaf blade, varying in color from green to pink.

Waterhemp: Producing up to 1,000,000 seeds per plant, waterhemp typically grows 4’-5’ fall, but can grow up to 12’ at a rate of 1” per day. Pollen from the weed can travel half mile or farther because of its cross pollination. Throughout the season, scout for weeds with glossy, elongated leaves that are hairless with stem colors ranging from light green to dark red.

Giant ragweed: This weed can produce more than 5,000 seeds per plant and can grow up to 17’ tall, commonly growing 1’-5’ taller than the crop. Giant ragweed has an initial competitive advantage over crops due to its early emergence and rapid growth rate. Scout for large, serrated leaves with 3 to 5 lobes, and long, coarse, fuzzy stems that branch into multiple leaves.

Horseweed (marestail): Producing up to 200,000 highly mobile seeds per plant, this weed can grow 5’-6’ tall at a growth rate of 3” per day. It is one of the first glyphosate-resistant weeds identified in U.S. row crops. Unaffected by crop rotation, horseweed seeds spread rapidly and can germinate year-round, but most often in fall or spring.

Last year, due to unpredictable and inclement weather conditions, many growers waited until post-emergence to apply an herbicide – at that point, many weeds had already reached their full height. Managing aggressive weeds this year requires a two-pass system, including both a pre-emergence and post-emergence herbicide application with multiple effective modes of action. Learn more about how to manage weeds with Resistance Fighter^® program from Syngenta, which provides education, local recommendations and a comprehensive herbicide portfolio to help growers and retailers effectively manage resistant weeds in their area.

Early-season Considerations for Cotton Growers

SyngentaAgronomy — Tue, 18 Apr 2017 22:03:30 +0000

As spring gets underway, so does the cotton planting season in key cotton-growing states. In a recent Cotton Farming magazine article, experts from across the Southeast, Arizona, and Texas weighed in on early-season planting considerations and disease and pest management programs. Sustained warm weather across many growing regions has led some growers to begin planting, but others have held off due to cool temperatures at night. Beyond soil temperature, there are other risks to consider when planting, including disease pressure and pests. Cool soil temperatures result in slow germination and increased susceptibility to seedling diseases caused by soil-borne fungi. Pathogens such as Rhizoctonia may cause seedling diseases. For excellent Rhizoctonia control, Syngenta recommends using Avicta® Elite Cotton Plus with Vibrance® seed treatment to protect against disease pressures early in the season. Post-emergence, turn to Quadris® fungicide to control leaf spot, blight, and other diseases.

Protect Your Soybeans from Invasive Nematode Damage

SyngentaAgronomy — Wed, 19 Apr 2017 21:23:41 +0000

With soybean planting beginning soon in many areas, it’s already time to prepare for the risks associated with the early growth stages - a critical time in soybean development. One such risk is the various nematode species that are present in the South:

Root knot nematode: This nematode is one of the most economically damaging plant-parasitic nematodes. Root knot nematodes can move freely in the soil and can also be easily transported by machinery, surface water or irrigation. Moisture or heat stress can increase soybean damage levels from root knot nematodes. Soybeans infested with root knot nematodes will exhibit signs of nutrient deficiency, including stunted growth and wilted leaves.
Reniform nematode: Each female reniform nematode can lay 40–70 eggs during her lifespan, which can lead to quick reproduction. According to the University of Arkansas, these nematodes typically disperse themselves across a field, rather than in hot spots, making them particularly difficult to control. Being proactive about management against reniform nematodes gives growers the best chances of control.
Lesion nematode: These nematodes have the ability to suppress root growth, causing an overall stunted soybean plant, which contributes to yield loss. Some lesion nematode symptoms include dark lesions and browning on the soybean plant; however, symptoms typically go unnoticed.

According to the University of Alabama, symptoms caused by nematodes are not usually specific enough to permit diagnosis by examination, so it’s important to sample soils and roots in order to understand what nematode pressures are affecting an operation. For the most accurate results, Syngenta recommends soil sampling in the late summer or fall. However, sampling in the spring to know what nematode pressures are an issue can help growers to plan accordingly, giving their soybeans a better chance to start strong. For protection against a wide variety of damaging nematode species, Syngenta recommends applying Avicta^® Complete Beans 500 seed treatment nematicide/insecticide/fungicide with Vibrance^® fungicide seed treatment. It offers proven, comprehensive protection, increases root health and helps to boost yields.

New Fungicide Options for Increasing Chickpea Acreage

SyngentaAgronomy — Thu, 20 Apr 2017 19:20:02 +0000

Growers in the U.S. are preparing to plant more acres of chickpeas than ever before. Many northern growers, looking for more profitable alternatives to wheat, are taking advantage of the growing chickpea market. Chickpea acreage is expected to increase by more than 50% this year, thanks in large part to a growing demand for gluten-free products. While increasing crop options is good news to growers, expanded acreage also means increased disease risk. There are a multitude of diseases that growers must face, but fortunately Aprovia® Top, a fungicide recommended by Syngenta, is active against many of them. By preventing sporangial infection and stopping fungal growth in leaf infections, Aprovia Top helps chickpea growers manage Ascochyta blight, powdery mildew, Alternaria blight, Asian soybean rust, Cercospera leaf spot and Mycosphaerella blight. Aprovia Top contains two active ingredients, Solatenol® fungicide and difenoconazole, to provide a measure of resistance management. Solatenol’s unique chemical structure increases its affinity to pathogens’ receptor sites and helps provide better disease control many other fungicides. It also binds tightly to the waxy layers of crop leaves, lengthening its residual disease activity. If you’re expanding your operation to include chickpeas or expanding your existing chickpea acreage, consider expanding your fungicide arsenal as well.

A Repeat Offender in Potato and Vegetable Fields

SyngentaAgronomy — Fri, 21 Apr 2017 19:42:48 +0000

When it comes to white mold, history tends to repeat itself. So the best way to control its cause, Sclerotinia sclerotiorum, is to avoid spreading it to uninfected fields and preventing germination in those where inoculum is present. According to a University of Florida Extension article for Growing Produce, the presence of small, black sclerotia and white, cottony-like mycelium are both indicators of white mold infection. The disease usually starts when the plant contacts infected soil or plant debris. In potatoes and fruiting vegetables, white mold symptoms first appear at flowering as water-soaked spots. As the disease progresses, it invades the stem causing girdling and eventual death of the upper part. Large portions of the field may become diseased, producing large, circular areas of dead plants. Control measures are most effective early in the season and can reduce the severity of infection as well as the potential carryover of sclerotia to the following season. Integrated management employing cultural, biological, and chemical control is essential for the successful management of disease. Syngenta offers several fungicide options to assist growers in their battle against Sclerotinia diseases. Omega® Top MP fungicide combines the power of fluazinam and difenoconazole to deliver long-lasting, broad-spectrum white mold disease control and proven performance for resistance management in potatoes. Quadris® fungicide offers optimal disease control to help vegetable growers effectively manage Sclerotinia diseases and maximize return on investment.

Pest Management: Scout Now for Wheat Diseases

SyngentaAgronomy — Mon, 24 Apr 2017 18:54:01 +0000

With this year’s mild winter, spring wheat is off to an early start. If favorable weather conditions occur this spring, wheat diseases could reach damaging levels. The University of Nebraska warns growers to begin monitoring the following wheat diseases:

Stripe rust: This disease has already been confirmed in numerous states throughout the country. When scouting, growers should look for yellow rust pustules in the upper and lower canopy. It’s important to remember that stripes typically don’t form until the disease is further developed, so looking for these pustules is key to an early diagnosis.
Leaf spots: Growers should be aware of tan spot and Septoria leaf blotch this season. In the early stages, symptoms for both diseases are similar. Growers should scout for spots with brown necrotic centers surrounded by yellow halos, beginning on the lower leaves before moving up the plant.
Powdery mildew: This disease is most likely to progress in humid conditions, typically developing on the lower leaves where humidity is highest. Growers should scout the lower canopy for white patches on the plant surface. These patches can turn to gray or brown later on.

Syngenta encourages growers to scout diligently and regularly throughout the season, increasing frequency as disease pressure grows. It’s important that growers get ahead of these diseases by identifying early symptoms and applying a fungicide in a timely manner. If growers find rusts, leaf spots or powdery mildew in their wheat fields, Syngenta recommends applying Trivapro^® fungicide, which provides long-lasting control of these key diseases. Trivapro delivers better residual control compared to competitive fungicide programs.

Be Ready for Early-Season Soybean Insects and Diseases

SyngentaAgronomy — Tue, 25 Apr 2017 19:48:50 +0000

With soybean planting kicking off, it’s important for growers to protect their plants from the start of the critical early-growth stages. Two of the biggest early-season threats to soybeans are insects and disease. Early-season insects:

Bean leaf beetle: This pest tends to emerge early, often at the beginning of May. According to Kansas State University, the bean leaf beetle is one of the most economically harmful soybean insects in the nation. Most of the damage is caused by foliage- and pod-feeding adults, which can significantly reduce seed quality and yield
Wireworm: This is another pest that tends to emerge early in the season. According to Purdue University, wireworms have the ability to completely hollow out a soybean seed. They can also cut off small roots or tunnel into the underground portions of young soybean plants.

Early-season diseases:

Fusarium spp.: This disease is especially harmful to soybeans during the germination period and can weaken plants, making them vulnerable to other pathogens as well. Fusarium species can cause the lateral roots to die and decompose, eventually leading to stunted and discolored leaves.
Rhizoctonia: This disease is most harmful to young soybean seedlings. According to the University of Minnesota Extension, high Rhizoctonia pressure can reduce soybean stands by more than 50 percent.

Syngenta recommends CruiserMaxx^® Vibrance^® Beans seed treatment, a combination of separately registered products, to help growers start their season strong by protecting vulnerable plants against yield-robbing early-season insects and diseases. With its proven performance, this fungicide/insecticide seed treatment reduces the risk of soybean stand establishment problems via the Cruiser Vigor Effect and allows soybeans to achieve a consistent yield advantage. This treatment can also help protect growers’ seed investment and avoid the need for costly replanting.

Subsurface Drip Irrigation for Row Crops

SyngentaAgronomy — Wed, 26 Apr 2017 20:51:54 +0000

Subsurface drip irrigation (SDI) is the most efficient method of delivering irrigation water directly to the crop root zone, according to the Clemson Cooperative Extension. In row crops such as cotton, yield can be increased or the same yield can be produced with less water. Installing an SDI system requires investment, but there are numerous benefits of subsurface irrigation that can help cotton crops. The positive effects of SDI on cotton yields are well-documented. In a three-year cotton study in South Carolina, SDI increased lint yield by an average of 65% — increasing revenue by almost $400 per acre per year. SDI can help reduce weed problems by keeping the soil surface dry. The systems are incredibly efficient, eliminating the risk of runoff and erosion as all water stays below the surface of the ground. Fertilizers can be fed directly to plants, and herbicide applications may be lessened due to less weed problems. In addition to using techniques like subsurface drip irrigation to maximize cotton yield, we recommend that you consider the available range of crop protection options from Syngenta. Avicta® Elite Cotton Plus with Vibrance® seed treatment provides best-in-class Rhizoctonia protection as well as broad-spectrum control of seed, soil and foliar insects. Besiege® insecticide, Gramoxone® SL 2.0 herbicide, and Quadris® fungicide control insects, weeds and diseases with proven performance.

Sudden Death Syndrome Could Strike Early-Planted Soybeans

SyngentaAgronomy — Thu, 27 Apr 2017 20:05:32 +0000

Soybeans infected with SDS Sudden death syndrome (SDS) is one of the most destructive soybean diseases, affecting the majority of soybean-growing areas. SDS is often found in fields also infested with soybean cyst nematode (SCN), because SCN feeding causes root damage and creates gateways for this pathogen to infect the plant. SDS is caused by the soil-dwelling fungus Fusarium virguliforme and flourishes in cool, moist conditions, putting early-planted soybeans at risk. Although early-planted soybean fields typically produce higher yields, the University of Nebraska advises growers to avoid early planting in fields with a history of severe SDS. Another way to reduce the chances of SDS infection is to avoid planting soybeans back to back, says the University of Missouri. Since there are no in-season treatment options for SCN or SDS, Syngenta encourages growers to take the necessary steps to control both of these pests during planting. Syngenta recommends growers plant NK^® Soybean varieties with resistance to both SCN and SDS. This preventive strategy will provide soybeans with a foundation of protection from these pests. For an added level of season-long protection against SCN, growers can apply Clariva^® Complete Beans seed treatment, a combination of separately registered products. Adding Mertect^® 340-F fungicide to this application will help further protect seeds from SDS during the early stages of development.

High-Risk Pests on Southeast Peanuts

SyngentaAgronomy — Fri, 28 Apr 2017 20:22:34 +0000

This peanut planting season, taking the necessary precautions against invasive species is a must. According to the University of Georgia Extension, growers should pay special attention to emerging seedlings as the next few weeks are regarded as a high-risk period for thrips. During the early stages of growth, plants are especially susceptible to the damaging effects of thrips. This can lead to a potential yield loss and opens the door to other viruses and diseases. In an attempt to manage these pests early, start with monitoring and scouting fields regularly. A thrips infestation will cause leaves to become distorted and covered in course stippling, and can cause them to also turn brown and die. In an effort to combat the effects of these tiny insects, remember to give plants adequate room to avoid overcrowding and provide proper irrigation and fertilization. To get ahead of the problem, Syngenta recommends treating peanut seed with CruiserMaxx® Peanuts insecticide/fungicide seed treatment, which offers growers more robust and vigorous crops and protection against chewing and sucking insects.

Pest Management: Winning the Battle Against Wheat Weeds

SyngentaAgronomy — Mon, 01 May 2017 22:06:34 +0000

Caption: Kochia The season-long battle between growers and annual weeds is only just beginning. However, taking an integrated approach to pest management can provide the necessary layers of control that will set the season up for success. Weeds are one of the top players that decrease wheat yields each year. Growers should be looking out for lamsquarters, ragweed, foxtail, Palmer amaranth, kochia, Russian thistle, mayweed chamomile and wild oat. Scouting & management tips:

Regularly scout fields to identify and control weeds early.
Document the presence of weed species before and after making product applications.
Keep an eye out for dead weeds near still-growing weeds within the same species. This can often be an indicator of developing resistance.
Rotate herbicides with different modes of action to help avoid resistance.
Incorporate an herbicide with multiple modes of action and chemical classes into your weed-management plan.
Always apply herbicides at the full, labeled rate and at the correct growth state to ensure the most effective control.
Consider implementing cultural practices such as tillage and crop rotation to extend the range of available herbicides and agronomic practices.

To control some of the toughest weeds, Syngenta recommends applying Talinor™ , a post-emergence herbicide that delivers excellent standalone control to broadleaf weeds, helping to protect yield and profit potential. Growers can also tank-mix Talinor with Axial^® XL or Axial Star to control grass and broadleaf weeds in a complete, efficient one-pass weed control. Incorporating weed control into pest management plans will provide wheat growers with a necessary level of protection to control weeds and help manage resistance to ultimately grow more wheat.

Facing Fears: What Flooded Fields Mean for Cotton

SyngentaAgronomy — Tue, 02 May 2017 22:25:12 +0000

With heavy rain and wind hitting parts of the Mid-South this past weekend, worries are sprouting up about potential damage to cotton fields. With signs of significant flooding, growers are fearful of losing usable acreage and already planted seeds. While there are ways to lower the risk for planted crops, combating these effects relies mostly on the decisions of Mother Nature. If fields are flooded, work toward bailing out water as quickly as possible. While some cotton may be able to survive, the risk of damage increases as water and low temperatures overwhelm the plant. With prevailing cool temperatures and more rain in the forecast, growers would be wise to hold off on planting during the next week or so. Cotton planted later in good conditions can catch up with already planted fields that were hit with cold temperatures. Once the weather remains consistently warm for 10-14 days, growers can begin to feel more confident that planting conditions are being met.

What All This Moisture Means for Corn

SyngentaAgronomy — Wed, 03 May 2017 16:34:44 +0000

If you feel like you haven’t seen consistently sunny skies in a while, you’re not alone. It’s been a wet few weeks throughout the U.S., reducing drought areas to record lows. While that may be good news overall, with extra moisture also comes flooding and standing water in fields. For corn growers who have already finished planting, flooding in fields poses a danger to root development that can make crops more susceptible to later-season drought. Early season disease likelihood also increases and plant growth can be stunted because of depleted oxygen in the soil, resulting in bare patches and poor stands. To minimize the impact of the recent weather to their hybrids, growers should consider the following:

Evaluate fields following rain: After rain stops, allow the field to dry for about 3 to 5 days before evaluating conditions.
- If corn has not emerged, check seeds for discoloration, a water-soaked appearance, and/or a rotting odor.
- If plants have emerged, split the stems and find the growing point of the plant, which should be below ground until around the V5/V6 stage.
  - Healthy growing point should be whitish in color and tissue should be firm.
  - Brownish, discolored tissue indicates damage.
- Continue to scout fields, flag a few suspect plants, and check for new leaf growth 4 to 5 days following the rain. Taking before and after pictures of plants can help determine if plants are growing properly.
Consider replanting: For fields where the rain’s impact was severe, consider whether a replant is necessary.
Scout flooded areas of the field throughout the year: These areas will most likely be the first to show signs of stalk rots, nutrient deficiencies, and possible other diseases. Conduct stand counts in both affected and unaffected areas to compare and estimate yield potential.

April Showers Bring … Corn Diseases?

SyngentaAgronomy — Thu, 04 May 2017 20:02:32 +0000

With scattered wet conditions greeting planters across the Delta, it might be difficult to think further into the season about what this means to your crops. But if you’re gazing at your planter through raindrops, now is the time to make a disease management plan. Proactively monitoring for and controlling key diseases throughout the season has lasting effects that can help your bottom line, even in times of tight commodity prices. Disease infection can severely damage a crop. It causes plants to focus on defense rather than growth. This can impact stalk strength, ear size and kernel production. Disease destroys green tissue, restricting the plants’ ability to convert sunlight into energy and thus die prematurely. We saw last season the dramatic implications of lack of disease control. In Kentucky, an application of Trivapro^® fungicide at R1 kept disease at bay to help the crop stay greener longer, as evidenced in the photo below. By protecting the green leaf tissue of the plant, Trivapro allowed the crop to put more energy toward producing yield instead of fighting disease. The added protection from Trivapro led to a yield increase of 60 bu/A.¹ Similar results were seen across the Delta – from 23 bu/A yield bump over untreated in Arkansas to longer-lasting disease control that preserved green leaf tissue in Louisiana. See these results here. Then check out the “Not Afraid To Work” landing page to see how Trivapro performed on other crops and across other areas in regards to:

Stronger stalks
Higher yield performance
Better crop health
Enhanced grain quality

Evaluating Corn Conditions during Stand Counts

SyngentaAgronomy — Mon, 08 May 2017 21:23:27 +0000

Planting is underway across the Midwest, and corn growers are eagerly awaiting the first signs of emergence. Once seedlings have reared their heads and produced 3-4 leaves, it’ll be time to conduct early-season stand counts to identify potential concerns with population and spacing. These stand counts are a great way to take note of a crop’s condition so far, especially considering the wet conditions that many growers have experienced this spring. It’s also a way to determine if additional management practices are necessary. A few of the key challenges that agronomists recommend growers evaluate during stand counts include:

Planter issues: Skips and gaps within the rows may be a sign that there was an issue with the planter. Although replanting at this stage might not be an option, this is great information for growers to keep in mind when conducting maintenance on their planter the following season. It’s important to note that the impact on yield will vary depending on the severity of the issue. Skips, for instance, will have more of a negative impact on yield than doubles.

Early-season pest pressure: It may be early, but pests such as cutworms and wireworms may already have begun feeding on seedlings, destroying yield potential down the road. Growers should monitor for any insect activity in their fields.

Field nutrition needs: Crops may need additional nutrients early in the season to thrive. When conducting stand counts, growers should watch for symptoms of common challenges like phosphorus, sulfur, and/or zinc deficiencies. In particular, soils that are sandy or have high pH will need closer inspection. Some early season nutrient deficiencies may be a sign of rooting restrictions resulting from cool weather conditions or sidewall compaction, rather than soil fertility.

Take Steps to Control Apple Scab

SyngentaAgronomy — Fri, 05 May 2017 19:44:51 +0000

If not controlled, apple scab can cause 70% or greater losses where humid, cool weather occurs during the spring months. In a recent article Kari Peter, assistant professor of plant pathology at Penn State University, warns that the dispersal of overwintering apple scab spores can cause outbreaks of the disease in apple trees around the region. She urges growers to scout and control apple scab early in the season. Open blossoms on apple trees can lead to the release of apple scab spores, increasing disease pressure. It is vital to apply fungicides to prevent these spores from causing new infections. For resistance management, apply no more than 2 complete sprays (4 half sprays) of products containing FRAC Group 7. Syngenta recommends a management program including Aprovia® fungicide for excellent control of apple scab and other diseases.

Saturated Soils Pose High Soybean Disease Risk

SyngentaAgronomy — Mon, 08 May 2017 22:57:35 +0000

Growers assessing wet conditions in Southern Illinois soybean fields. It’s wet. Across the Midwest and South, soggy soybean fields are slowing growers down at an ideal time for planting. With this wet weather not only comes delays in everyday operations, but it also leads to more long-term concerns: Am I going to experience runoff? Are my soybeans going to emerge healthy? Are my soybeans going to emerge at all? Am I ever going to get back in the fields? However, one of the biggest threats still to come is that of soybean seedling disease. The University of Minnesota Extension says seedling infections can cause damage that will persist throughout the growing season. Saturated soil conditions are favorable to the development and spread of disease, such as Phytophthora, Pythium and Fusarium. Although all growers should be closely scouting to stay on top of potential disease presence in the coming weeks, those who used a fungicide seed treatment can consider their soybeans at a lower risk for infection than those who did not. Syngenta recommends using CruiserMaxx^® Vibrance^® Beans seed treatment, a combination of separately registered products, to mitigate potential disease risk and improve yields. CruiserMaxx Vibrance Beans provides effective protection against major fungal diseases by creating healthier, more robust root systems. Through the Cruiser Vigor Effect, soybeans will emerge quicker, furthering the reduction of seedling disease risk and providing better yield performance and stability. With unpredictable weather each season, having an insurance policy like a seed treatment can be a crucial component to protecting yield. Investing in one can provide security to your soybeans all season long. Sign up for the Know More, Grow More Digest to receive twice monthly agronomic e-mail updates pertinent to your area.

Overwintered Aphids Active Early in Wheat

SyngentaAgronomy — Tue, 09 May 2017 19:21:42 +0000

The unusually warm winter may prompt aphids to emerge in larger numbers and earlier in the season, compared to previous years. While aphids don’t always pose a problem if they remain below the determined threshold, they can transmit barley yellow dwarf virus (BYDV), the most widespread and economically important virus disease of wheat. According to Ohio State University, BYDV infections cause the most damage in fields with overwintered aphids. The virus can reduce tillering, cause sterility and damage kernels. Growers often overlook the early symptoms of BYDV, such as yellowish-green leaf blotches, because those symptoms are often mistaken for mineral deficiencies. Sometimes, symptoms appear 2-3 weeks after aphids are gone, resulting in a failure to associate BYDV with aphids. Syngenta management solution

Protect your crop from the start with a seed treatment.
Scout fields early in an “X” or “Z” pattern for pests.
Note any predator insects, such as lady beetles, which can help control aphids.
Apply an insecticide at locally established thresholds to keep populations to a minimum.

Syngenta recommends choosing a seed treatment like Cruiser^®5FS seed treatment insecticide, which protects wheat and barley crops from fall aphid attacks and serves as a first line of defense against BYDV. With Cruiser, protection is in place from the moment seeds are planted, and it works systemically to protect young plants as they grow. High yields begin with a strong start when your crop needs the most help. Understanding your field history can help you tailor a crop protection program that will be most effective against yield-robbing pests.

Protect Corn, Soybean Yields with Post-Emergence Herbicides

SyngentaAgronomy — Tue, 16 May 2017 18:30:30 +0000

It might not look identical from state to state, town to town or even field to field, but weed pressure is everywhere. Growers can’t afford to let weed competition threaten yield potential – that’s why season-long weed management is essential. What to do? Weeds depend on routine to survive. Growers need to build diversity into their weed management programs to prevent further development of herbicide-resistant weeds. Weed management programs that rely on one herbicide increase the potential for herbicide-resistant weeds to develop. As a result, the herbicides used to control these weeds may become ineffective. Syngenta has a strong lineup of post-emergence corn and soybean herbicides:

Corn: Halex® GT tank-mixed with dicamba or atrazine helps maintain clean fields throughout the season. Halex GT can be applied as a post-emergence only treatment. Halex GT can also be used following Acuron®, Acuron Flexi, Lumax® EZ or Lexar® EZ herbicides for season-long control of annual grass and broadleaf weeds, helping your customers grow more corn.

Chart caption: Halex GT can be applied up to 30-inch corn, but when growers apply Halex GT to weeds under 4 inches tall, they can see a 12 bu/A yield advantage.

Soybeans: Flexstar® GT 3.5 herbicide offers post-emergence control of weeds that are difficult to control with glyphosate alone. Using Flexstar GT 3.5 after Boundary® 6.5 EC herbicide or BroadAxe® XC herbicides helps control stubborn weeds all season long.

Caption: Untreated (Left) vs. Boundary 6.5 EC followed by Flexstar GT (Right). Controlling weeds requires full-season attention. Growers who scout early and use multiple modes of action in their post-emergence herbicide program can prevent weeds overtaking their corn and soybean fields, fight resistance all season long and achieve higher yield.

Corn Herbicide Flexibility Matters in Cool, Wet Conditions

SyngentaAgronomy — Tue, 09 May 2017 21:13:54 +0000

Caption: Pana, IL: A rain gauge shows just over 5” of rainfall from April 26 through May 2, 2017. Even the best plans can be thwarted by bad weather. Wet and cold weather can make the corn herbicide application window smaller, and in many cases growers can completely miss it if the crop exceeds the planned herbicide’s application window. It’s important to have a herbicide that delivers flexibility and crop safety* regardless of weather conditions. The application flexibility Acuron® corn herbicide provides allows growers to apply their herbicide even with bad weather conditions. Acuron delivers broad-spectrum control of 70 plus tough broadleaf weeds and grasses, and can be applied 28 days pre-plant up to 12-inch corn. Acuron Flexi corn herbicide provides additional flexibility, particularly in areas where atrazine use is limited. By allowing for application from 28 days pre-plant up to 30-inch corn, Acuron Flexi provides the flexibility growers need to best suit their fields and control tough weeds. It’s important to be prepared for the unexpected. By selecting a herbicide with application flexibility, growers can worry less about adverse weather conditions and focus on growing more corn.

Scouting Sheath Blight in Rice

SyngentaAgronomy — Wed, 10 May 2017 22:07:05 +0000

If your rice crop has reached or is past green ring (internode elongation), it’s time to start scouting for sheath blight. Favored by warm temperature and high humidity, sheath blight can cause significant yield loss in susceptible cultivars if left unchecked. Conditions that favor sheath blight are susceptible cultivars, high N rates, dense stands with thick canopies, and field history of sheath blight or aerial blight. As summer approaches and temperatures rise, take steps to prevent and treat sheath blight in your rice crop. It is important to begin scouting for sheath blight immediately, to head off the disease before it can take hold. The lesions start small, developing from greenish gray to dark brown. Fungicides should be applied when levels of sheath blight go beyond the recommended threshold. Syngenta recommends Quadris® fungicide for proven performance in controlling sheath blight and other harmful diseases.

Top 10 Weed Resistance Management Stewardship Principles

SyngentaAgronomy — Thu, 11 May 2017 19:46:15 +0000

Dicamba, the new tool in the soybean weed management toolbox, will improve control of certain weed species. But, it won’t revive the days of a post-emergence-only weed control program. Those days are history, and from them, growers have learned an important lesson: Misusing technology will result in an early expiration date. To prolong the efficacy of existing herbicides – like dicamba – for future generations of growers, keep these resistance management principles in mind:

Do not rely solely on post-emergence herbicides.
Start clean, utilizing tillage or an effective burndown PLUS a pre-emergence residual herbicide application.
Apply full rates of pre-emergence herbicides with recommended adjuvants.
Use multiple effective modes of action with efficacy on target weeds.
Avoid allowing weeds to go to seed.
Use diversified management programs, incorporating mechanical weed control and crop rotation.
Remove any escapes early: Hand weed, spray or cut out patches.
Utilize good agronomic practices: narrow rows, increased plant populations, and other practices that promote crop growth and competitive ability.
Clean tillage, seeding and harvest equipment when leaving fields that are infested with herbicide-resistant weeds.
Use a two-pass pre- and post-emergence system, incorporating the principles above.

Weed resistance to existing and new herbicides is just a matter of time, but growers have the power to decide when that will happen in their fields.

Disease Alert: Strawberry Fruit Infection Risk High in Southeast

SyngentaAgronomy — Thu, 11 May 2017 20:53:14 +0000

Infection risk for Botrytis rot, commonly known as gray mold, is high this week in the North Carolina per the Strawberry Fruit Infection Risk Tool. With rain in the forecast, NC State Extension recommends a fungicide application if flowers and/or fruit are present and the last fungicide applications was more than 7 days ago. Botrytis rot is a serious disease in all strawberry production areas that can cause problems not only in the field, but also during storage, transport, and marketing of strawberry fruit. The symptom most commonly observed is rotted fruit with growth of a velvety gray mold. In Fungicide Selection for Botrytis and Anthracnose Fruit Rot Management 2017, growers are encouraged to implement a program including Switch fungicide for effective Botrytis rot control. Switch^® fungicide is a prepack mixture fungicide that combines two highly effective active ingredients that offer outstanding control of gray mold (Botrytis) and other important diseases in strawberry crops. Switch attacks disease pathogens at four different stages in the pathogen life cycle to provide long-lasting control at low use rates.

Grow More Wheat With Early-season Weed Control

SyngentaAgronomy — Thu, 11 May 2017 21:14:15 +0000

When weeds compete, wheat yields suffer. Early-season competition from weeds like kochia, wild oat, marestail and Russian thistle reduces moisture and nutrient uptake, limiting grain fill, while late-season pressure offers its own set of unique pitfalls:

Heavy infestations of weeds at harvest can slow or even stop combines in their tracks
Depending on the species, weeds that go to seed deposit anywhere from a few hundred to one million seeds per plant into the seed bank, ensuring weeds are a persistent problem for years to come
Resistance can quickly spread if a resistant weed goes to seed
Combines can carry weed seeds into previously unaffected fields

Minimize the risk of yield loss and late-season weed pressure by employing a start clean, stay clean approach to wheat. We recommend starting clean with a burndown application followed by a post-emergence application of Talinor^TM cereals herbicide for season-long broadleaf weed control. Talinor combines two modes of action (groups 6 and 27) and controls more than 45 broadleaf weeds, including those with resistance to ALS-inhibitor, synthetic auxin and glyphosate herbicides. When combined with Axial® XL (group 1) or Axial Star (groups 1 and 4), multiple modes of action provide one-pass broadleaf weed and grass control.

Take Frogeye Leaf Spot Seriously this Season

SyngentaAgronomy — Fri, 12 May 2017 20:46:16 +0000

According to University of Nebraska, frogeye leaf spot (FELS) contributed to an estimated yield loss of 30% across the country last year. It’s primarily an issue in Southern states, but it has been known to impact soybean fields in other regions as well. When scouting for FELS, Purdue University advises growers to inspect leaves for small, yellow spots that can be up to ¼ inch in size. These lesions are gray to brown in the center, surrounded by violet-red margins. Since this disease is residue-borne, it becomes most severe when soybeans are planted in succession in the same field, so it’s best to rotate crops in fields that have been infected with frogeye leaf spot when possible. Syngenta encourages growers to scout diligently and regularly throughout the season, increasing frequency as disease pressure grows. Growers who stay on top of FELS by identifying symptoms as soon as they appear will have a better chance against this disease. If growers find FELS in their soybean fields, Syngenta recommends applying Trivapro^® fungicide, which provides long-lasting, preventive and curative disease control and delivers crop enhancement benefits to help produce fuller pods.

Get Ahead of Phytophthora Root Rot

SyngentaAgronomy — Mon, 15 May 2017 22:26:14 +0000

With several years of drought affecting the West, fruit and nut growers are now facing an underground issue. With Phytophthora root rot infecting the tissue of plants, issues like poor vegetative growth, long-term orchard decline, and possible tree death begin to increase. Magnified by irrigation changes, the recent wet winter, and salty water, Phytophthora is making its way through the soil of California. The best way to detect for infection is by digging up roots and getting tissue tested for the presence of a specific Phytophthora protein. Not treating the disease can have a significant impact on yield. Syngenta offers the Soil Pathogen Assessment (SPA), a free program that assesses Phytophthora infections on a field-by-field basis. Contact your Syngenta representative to learn more about soil sampling through the SPA program: www.Syngenta-US.com/rep-finder. To combat this disease, water management is key. Make sure the soil is not too saturated, as this can allow the Phytophthora mold room to live and grow. In addition, consider applying a fungicide like Ridomil Gold® SL. By applying Ridomil Gold SL, growers can expect to see improved stand, root health and crop vigor to help maximize return on investment.

Managing Resistance in Wheat With Multiple Modes of Action

SyngentaAgronomy — Wed, 17 May 2017 19:20:33 +0000

Caption: Foxtail in a wheat field. There are many factors that result in poor weed control in wheat and barley: a thin crop stand, extreme weather conditions, plugged nozzles, improper application of herbicides, generic formulations, ill-advised tank mix partners or some combination of these factors. The one factor impacting even the most seasoned growers though, is tough, resistant weeds. As weed resistance has spread, many current weed control programs have shown diminished effectiveness, threatening farm profitability and farm legacy for future generations. The first step in managing resistant weeds is evaluating the previous year’s herbicide program to determine what worked well and what areas need improvement. In particular, take note of problematic fields and the weed species within those fields that were difficult to control. Then implement a new weed control program that uses multiple, effective modes of action*. We recommend tank mixing Talinor^TM herbicide with Axial® XL or Axial Star herbicide for efficient, one-pass grass and broadleaf weed control. Talinor has two effective modes of action (groups 6 and 27) and controls more than 45 tough broadleaf weeds, even those with known resistance to ALS-inhibitor, synthetic auxin and glyphosate herbicides. Axial XL (group 1) or Axial Star (groups 1 and 4) can be mixed with Talinor to add grass control, with Axial Star also providing enhanced control of Kochia. *It’s also important to remember that proper application timing and using full, labeled rates helps fight the development of herbicide resistance and will ultimately help grow more wheat.

Early-Season Bean Leaf Beetles Have Arrived

SyngentaAgronomy — Thu, 18 May 2017 21:55:32 +0000

Caption: Bean leaf beetle In light of the mild winter and wet spring, University of Arkansas extension entomologist Gus Lorenz predicts 2017 will be a “bug year.” Lorenz told Syngenta Pest Patrol that he’s already seen multiple reports of bean leaf beetles in young soybean fields across the Mid-South. One report was from Angus Catchot, extension entomologist at Mississippi State University - he tweeted that bean leaf beetle populations have already reached the economic threshold in his area. According to The Ohio State University, late-planted soybeans typically miss first-generation bean leaf beetles; but, may experience second-generation pressure during their early, vulnerable stages of development. Purdue University highlights some of the damage caused by bean leaf beetles:

Overwintering adults feed on stems and leaves of early-emerging soybeans - stand losses are possible at this stage of growth.
Once maturing leaves become less attractive, beetles feed on the green tissue of pods, leaving a thin membrane over the seed.
During pod maturation, the pod membrane often cracks, leaving an entry hole for airborne plant pathogens, resulting in discolored, moldy, shriveled, and/or diseased beans.

Lorenz advises growers to begin scouting for bean leaf beetles now, before they contribute to damage and yield loss. Once bean leaf beetles and other insect pests reach the economic threshold specific to each region, growers should consider applying Endigo^® ZC insecticide for quick knockdown and extended residual control to grow more soybeans and maximize profit potential.

Increased Risk for Powdery Mildew in San Joaquin Valley Vineyards

SyngentaAgronomy — Fri, 19 May 2017 17:21:36 +0000

Because of severe powdery mildew pressure last year and heavy winter rains, Western Farm Press suggests growers in the San Joaquin Valley prepare for increased disease risk in grapes this year. University of California Extension reports powdery mildew is best managed through early reduction of inoculum and maintaining a suitable treatment regimen. Chlorotic spots on the upper leaf surface are the first signs of powdery mildew, followed by white mycelium on the lower leaf surface. When spore production begins, the areas infected by the pathogen begin to take on the powdery white appearance from which the disease gets its name. Syngenta offers fungicides that help control powdery mildew in grapes, such as Inspire Super® and Quadris Top® fungicides. Both Inspire Super and Quadris Top possess preventive and curative properties and offer rapid uptake into plant tissues with systemic and translaminar movement. As with most diseases, it is easier to use preventive treatment than to try and rescue grapes from established infections.

Mid-Season Tough Weed: Kochia

SyngentaAgronomy — Mon, 22 May 2017 19:26:03 +0000

All the hard work put into planting can go to waste if the crop faces unchecked competition from tough weeds like kochia. North Dakota State University warns that kochia is extremely competitive and, if left uncontrolled, can result in severe yield loss. At maturity, this weed breaks off at the stem, allowing it to tumble across fields and disperse its seed. One kochia plant can produce as many as 50,000 seeds, so it’s important to recognize and manage this weed before it goes to seed. Identification:

Leaves are thin, 1-2 inches long, fuzzy and gray-green in color
Stems are highly branched, yellowish-green to green and often turn red with maturity

To stay on top of kochia, scout fields thoroughly and treat the weed before it reaches 4 inches in height. Always remember to use full labeled rates and stay up-to-date on the latest herbicide resistance developments. A post-emergence application of a robust herbicide, like Acuron^®, Acuron^® Flexi or Halex^® GT in corn, and glyphosate in soybeans, should contain differing modes of action from residual products. By treating kochia with multiple effective modes of action and using cultural weed removal practices, you can help avoid a weed infestation the following season and help manage resistance in your field.

Three Things to Consider When Replanting Corn

SyngentaAgronomy — Mon, 22 May 2017 19:51:06 +0000

Wet conditions during corn planting have growers facing a tough decision: replant or hold firm. We recommend growers choosing to replant consider the following:

Start clean…again: Ensure the original corn crop is eradicated before replanting. If it’s allowed to emerge after replanting, it will rob water and nutrients from the replanted corn. We recommend shallow tillage, as this will eradicate the first corn crop without burying your pre-emergence herbicide application so deep that it loses effectiveness.

Do not reapply: For growers that started clean with an application of Acuron® or Acuron Flexi corn herbicide, reapplication is not necessary. Acuron and Acuron Flexi will remain in place unless there has been significant movement of soil across the field.

Scout: Scouting is critical. We recommend scouting early and often, especially around the V3 and V4 stages. If you applied a full rate of Acuron (groups 5, 15 and 27) or Acuron Flexi (groups 15 and 27) pre-emerge you shouldn’t have to respray, but should scout just to be sure. If you planned a two-pass herbicide application, both Acuron and Acuron Flexi offer application flexibility – up to 12” corn for Acuron and up to 30” corn for Acuron Flexi. A two-pass system can also utilize a post-emergence application of Halex® GT corn herbicide (groups 9, 15 and 27) for an additional mode of action. Halex GT offers application flexibility from post-emergence up to 30” corn.

Armyworms Begin to Forage Soybeans

SyngentaAgronomy — Tue, 23 May 2017 22:03:37 +0000

Caption: Fall armyworm As many entomologists predicted, the mild winter and wet spring have created perfect conditions for early pressure from insects this season. Recent entomologist reports indicate that some insect populations are already approaching economic thresholds in the Mid-South. Gus Lorenz, extension entomologist at University of Arkansas, told Syngenta Pest Patrol that he’s already received reports of a complex of armyworms, up 5 to 6 per row foot, feeding on soybean seedlings. According to Alabama Cooperative Extension System, armyworm damage often appears suddenly. They typically feed at night undetected, but they can also feed early in the morning or during the day. When not feeding, they can be found in the debris at the base of plants or slightly under the soil. Lorenz advises growers to scout particularly well this year due to the heavy pest pressures appearing so early in the season. Once armyworms and other lepidopteran insects reach the state-determined economic threshold, growers should consider applying Besiege^® insecticide for quick knockdown and extended residual control to grow more soybeans and maximize profit potential.

The Pigweeds Prone to Escape

SyngentaAgronomy — Tue, 23 May 2017 21:06:38 +0000

Sound the alarm: The University of Illinois urges growers in the Midwest to rethink their waterhemp and Palmer amaranth management plans. If waterhemp and Palmer amaranth aren’t controlled early in the season, they risk going to seed and passing their herbicide-resistance genes to new generations. Waterhemp has already demonstrated resistance to 6 different herbicide groups. Waterhemp In 2016, the University of Missouri identified a Palmer amaranth population with resistance to both glyphosate and PPO inhibitors. A major weed of concern in the South, Palmer amaranth is quickly spreading across the Midwest and was identified in Minnesota for the first time in 2016. Palmer amaranth If left unchecked, Palmer amaranth has the potential to completely wipe out yield, and its relative, waterhemp, can rob growers of between 42 - 48% of their yield. Because these pigweeds can germinate throughout the season, managing them requires:

Extensive scouting
A two-pass pre-emergence and post-emergence herbicide program
Multiple effective modes of action
Mechanical weed removal practices

To tell the two apart, examine the shapes of their seedling leaves and the length of the petioles. The seedling leaves of Palmer amaranth are egg-shaped, with the petiole often longer than the leaf blade, while the waterhemp plants have narrow, lanceolate-shaped leaves. The first step in managing Palmer amaranth and waterhemp and delaying resistance in your field is boosting your resistant weed knowledge: Take the Weed IQ Quiz and see how you score as a Resistance Fighter^®.

Protecting Against the Colorado Potato Beetle in Potatoes

SyngentaAgronomy — Wed, 24 May 2017 21:11:44 +0000

The Colorado potato beetle can cause significant losses in potato crops. In Growing Produce, University of Wisconsin-Madison Professor and Vegetables Extension Specialist Russell Groves provides some tips to help potato growers manage Colorado potato beetle populations. Growers can roughly predict the emergence of the Colorado potato beetle with the aid of degree day models, because the pest overwinters near places where potatoes were planted in the year prior. Because the newly emerged beetles are not heavy feeders, it is best to apply insecticide treatments at the first and second instar stages of the first generation. Good crop rotation practices are also an important management method. For excellent control of Colorado Potato beetle and other harmful potato pests, Syngenta recommends Minecto® Pro insecticide, a broad-spectrum, foliar insecticide that harnesses the power of two complementary active ingredients.

Protecting Cotton Herbicides

SyngentaAgronomy — Thu, 25 May 2017 16:12:40 +0000

In the herbicide world, sticking only with what works today may render it useless tomorrow. This is true for new herbicide tools and those already in use. Several articles published by Delta Farm Press focused on information presented at Pigposium 3, a recent herbicide resistance meeting in Forrest City, AR. Weed scientists addressed the audience about a variety of topics surrounding the challenges of weed resistance, including how rapidly resistance can develop, the threat of weeds with multiple resistance and what should be done to protect the herbicide tools that are available. To protect the chemistries that are available, it is important to mix them up. If a herbicide is working, then don’t rely on it exclusively. Gramoxone® SL 2.0 herbicide delivers excellent early weed control bringing convenience, flexibility and dependability. It even works in cool, wet weather and is compatible with water of various qualities and nitrogen fertilizers containing calcium. In the ongoing battle against weed resistance, this versatile burndown and pre-plant solution is one more tool in a much needed kit.

Mid-Season Tough Weed: Horseweed (Marestail)

SyngentaAgronomy — Tue, 30 May 2017 22:03:45 +0000

Caption: Horseweed (marestail) As young corn and soybean plants continue to grow, growers should look out for horseweed (marestail). This annual weed typically germinates in the fall or spring but also has the unique ability to do so year-round. Purdue University says that crop rotation doesn’t affect horseweed, so knocking down this weed before its highly mobile seeds spread throughout the field offers the best chance of control. Horseweed is often misidentified as whitlowgrass or a member of the fleabane species, so paying special attention to its characteristics is the key to an accurate diagnosis. Identification

Forms a rosette soon after emergence
Can grow up to 6 feet tall
Leaves decrease in size toward the top of the weed

At this point in the season, applying a post-emergence herbicide can help control horseweed and prevent future seed dispersal. With the increasing threat of herbicide resistance, the University of Nebraska-Lincoln reminds growers to consider choosing a herbicide containing multiple effective modes of action. Acuron^®, Acuron^® Flexi or Halex^® GT herbicides for corn, and Flexstar^® GT 3.5 herbicide for soybeans can help control horseweed and other tough weeds, while also helping manage resistance to herbicides in future seasons.

Frogeye leaf spot: Learn to Combat This Soybean infection

SyngentaAgronomy — Wed, 07 Jun 2017 17:55:49 +0000

With predicted rain and warm weather moving through the South this summer, the risk of humidity increases. These are perfect conditions for spreading a disease like frogeye leaf spot. As the weather patterns move it is only a matter of time before frogeye leaf spot reaches the Midwest. With the potential to damage crop yield and revenue, now is the time for growers to pay special attention for signs of this disease. Frogeye leaf spot causes dark, irregular lesions on the leaves, causing them to wilt or drop prematurely. When the disease attacks the soybean pods, reddish-brown spots appear, with the fungus traveling through the outside wall and infecting the mature seeds. If the infection is severe enough, yields can significantly decrease. If untreated, the disease can survive through winter and return to attack the plants next growing season. To combat frogeye leaf spot, Syngenta suggests applying Quadris Top^® SBX fungicide. This fungicide offers soybean growers the most robust formulation for broad-spectrum preventive and curative disease control, and can help increase yields and deliver a potential higher return on investment. Quadris Top SBX also provides:

Increased periods of photosynthesis for more plant growth and higher yield potential
Improved plant health for larger beans, fuller pods and improved pod retention

Tips to Prevent This Spinach Virus

SyngentaAgronomy — Wed, 31 May 2017 19:06:09 +0000

As explained in an article from University of Arizona Cooperative Extension, curly top disease in spinach can be caused by two viruses in the Curtovirus group, the beet curly top virus and the spinach curly top virus. Both are transmitted from infected to uninfected plants by the same vector, the beet leafhopper. The beet leafhoppers will leave drying vegetation in the fall to feed on new growth in agricultural fields. Those nymphs that aren’t infected will soon get the disease by feeding on weeds and infected plants. When a spinach crop is infected, you’ll notice stunted growth and leaf discoloration and distortion. There are a few ways to help prevent the infection and spread of curly top virus:

Late plantings are helpful to avoid the beet leafhopper migration. Not only are leafhoppers more likely feed on other vegetation before your plants, but because the temperatures are dropping, their feeding frequency will decrease.
Scout your fields and remove plants that you know are infected with the disease. Eventually the disease will take over the plant and it will no longer produce. While it may be hard to detect these insects, if there are large populations on a plant, a quick shake of the plant will reveal their location.
Because weeds are a great location for beet leafhoppers to set up residence, a program to help control weeds is a good start to keeping these pests away.

Weeds to Watch in Barley and Wheat: Kochia, Wild Oat

SyngentaAgronomy — Thu, 01 Jun 2017 21:25:23 +0000

Caption: Wild oat in a wheat field. Kochia and wild oat are two of the toughest, yield-robbing weeds in barley and wheat and require effective management. Listen as Brent Lackey, Syngenta product lead, herbicides, explains why each is a weed to watch out for: [audio mp3="http://www.knowmoregrowmore.com/wp-content/uploads/2017/06/Brent-L-Audio-for-KMGM.mp3"][/audio]

	Weed: Kochia	An erect (0.3-1.5 m tall) profusely bushy branched annual with fine textured foliage. Seedlings are often, but not always, pink underneath. The seedling forms as a rosette and have long hairs on the surface. As plants grow, they are blue-green to gray-green in color but take on a reddish or purplish coloration later in the season. The flowers of kochia lack petals and instead, have 5-winged sepals that are green in color.
	Weed: Wild Oat	Roots are extensive and fibrous. Stems are smooth, stout, about 2’-3’ tall and in bunches of 3-5 hollow stems. Leaves are long and thin, about 2.5”-8” long and about ¼”-¾”wide.

For effective control of kochia and wild oat, we recommend an application of Talinor^TM herbicide tank mixed with either Axial® XL or Axial Star herbicide. Talinor combines two modes of action (groups 6 & 27) and effectively controls kochia and 44 other problematic broadleaf weeds. Combining Talinor with Axial XL (group 1) adds control of grasses like wild oat. Axial Star (groups 1 and 4) contains two modes of action for grass / wild oat control and additional activity against kochia. ^Audio“Wild Oats.” Manitoba Agriculture, Food and Rural Initiatives.

Predicted Wet Summer Favorable for Frogeye Leaf Spot

SyngentaAgronomy — Fri, 02 Jun 2017 13:41:47 +0000

The Climate Prediction Center predicts above-average rainfall over the next three months in the Central and Northern Plains. High rainfall and warm summer temperatures favor frogeye leaf spot (FELS) development in soybeans. The University of Nebraska-Lincoln adds that rain, in addition to wind, can also help disperse FELS spores, spreading the infection. Untreated (top) and Trivapro R3 (bottom) Source: Joe Wuerffel, R&D. *Based on 9 large plot trials in the U.S. in 2016 FELS infection is most visible in the younger, more vulnerable leaves of the upper canopy. Initially, symptoms appear as small, dark spots on the leaves and eventually enlarge and become gray to brown with a reddish purple border. With strobilurin resistance on the rise, treating FELS at the R3 growth stage with a fungicide that contains multiple modes of action is an effective management option. In addition to providing preventive and curative FELS control, Trivapro fungicide contains three proven modes of action and has crop enhancement benefits that help plants produce stronger pods with larger beans. Ryan Larson, a grower and retailer in Blooming Prairie, MN, states that with the wet, saturated conditions we had, Trivapro did a good job of keeping the soybeans clean and free of frogeye leaf spot.

Pest Alert: Citrus Greening and Asian Citrus Psyllid Found in Florida Panhandle

SyngentaAgronomy — Fri, 02 Jun 2017 21:39:08 +0000

The Huanglongbing (HLB) disease, also known as yellow shoot or citrus greening, is a fast-spreading disease that is on the rise in the U.S. According to a report from the University of Florida Extension, there are newly confirmed cases of the disease on citrus trees in the Panhandle of Florida. The carrier of the disease, Asian citrus psyllid (ACP), has also been reported in the area. And where you have ACP, you will likely find HLB. The first sign of infection is the yellowing and thickening of leaves and the corky appearance of veins. The fruit will also appear small, discolored and uneven in growth; the taste may be extra sour. When trees are severely infected, sometimes the only course of action is to dig up the tree altogether. While the majority of mature, fruit-bearing trees in Florida groves are assumed infected, there are still opportunities to help prevent disease proliferation. In the case of young, new plantings that are not yet infected, curtailing psyllid populations is priority number one. The adult insect is winged with black coloration on the tips of the wings, and feeds from a vertical position, with wings rising into the air. Nymphs have a flat, yellow body and leave behind white honeydew and distorted leaves as they feed. Controlling its vector, ACP, is a primary tactic in managing HLB and slowing its spread. Minecto® Pro insecticide, the premix formulation of cyantraniliprole and abamectin, offers long-lasting residual control of a broad-spectrum of key citrus pests, including ACP, citrus rust mites and citrus leafminers.

Mid-Season Tough Weed: Palmer Amaranth

SyngentaAgronomy — Mon, 05 Jun 2017 23:15:48 +0000

Caption: Palmer Amaranth Out of a number of problematic weeds to watch for, Palmer amaranth remains a top threat across most soybean- and corn-producing regions. Purdue University characterizes Palmer amaranth as a particularly problematic weed because of its ability to produce 100,000 to 1/2 million seeds per plant, easily disperse its seeds and compete aggressively with crops by growing 2 to 3 inches per day. Palmer amaranth is unpredictable – it can emerge at any point in the season. Because of its erratic nature, growers should begin scouting for this weed now and continuously to do so throughout the season. Identifiers:

Diamond-shaped leaves varying from green to pink
Seed heads grow up to 30 inches long
Could have white, V-shaped markings on the leaves

Palmer amaranth is best controlled before it reaches 4 inches in height. Because of its ability to quickly adapt and spread herbicide-resistant genes, it is essential that growers select a proven treatment containing multiple modes of action. Syngenta recommends growers consider using herbicides, such as Acuron^®, Acuron^® Flexi or Halex^® GT for corn. For soybeans, growers should apply Flexstar^® GT 3.5 herbicide to takedown an aggressive weed like Palmer amaranth. In preparation for scouting, take the Resistance Fighter^® Weed IQ Quiz to test your weed identification knowledge.

In recent years, Northern corn leaf blight (NCLB) has become a more prevalent disease within the Corn Belt, and growers should be aware this season. According to Purdue University, the NCLB fungus survives through the winter on infected corn residue at the soil’s surface. As temperatures rise in the spring and early summer, the fungus produces spores on this residue, which are then splashed or wind-blown onto leaves of emerging corn. With a mild winter and wet spring, NCLB will likely be an issue this year if we see a warm, humid summer. NCLB can cause significant yield loss if it develops prior to or during silking. The earlier NCLB infects a plant, the higher the potential for yield loss. Identifiers:

Olive green or black fungal spores
Long, narrow lesions down the leaf
Oblong lesions on the leaf tissue

Although scouting is a crucial component to maximizing yield, plants can be infected up to 12 days before symptoms begin to show. Syngenta encourages growers to treat proactively in regions that have been effected by NCLB in past years. Applying a fungicide before NCLB develops is the most effective way to avoid damage that could hinder photosynthesis. Syngenta recommends growers apply Trivapro^® fungicide for preventive and curative disease control to maximize yield and profit potential this season.

What’s In a Herbicide?

SyngentaAgronomy — Wed, 07 Jun 2017 20:56:53 +0000

As discussed in the post, Part 1: More Powerful Weed Control, More Often, it’s important to know the facts about what components are in your herbicides and how effective each component is on weeds in your area. As more mesotrione-containing premixes enter the market, it’s important to ask yourself, “Am I getting the same active ingredients in any mesotrione premix?” The answer? No. While many herbicides contain mesotrione, the other active ingredients used are also important for weed control. And only Acuron® and Acuron® Flexi corn herbicides have bicyclopyrone, which gives them unrivaled, consistent control of tough broadleaf weeds. Bicyclopyrone was designed to complement mesotrione, so both HPPD-inhibitors work together to deliver powerful weed control. Even on its own or in combination with other active ingredients like atrazine, bicyclopyrone helps the Acuron brands deliver powerful control. Below is a comparison of bicyclopyrone compared to clopyralid (better known as Stinger®), one of the active ingredients in Resicore®. Bicyclopyrone (with or without atrazine) provides greater control of waterhemp 14 days after treatment (DAT) than Stinger (alone or with atrazine).

Don’t Let Phytophthora Ruin Soybean Fields

SyngentaAgronomy — Thu, 08 Jun 2017 14:46:20 +0000

Conditions in many parts of the Corn Belt have been just warm and wet enough for Phytophthora root rot to crop up in many soybean fields. The pathogen, which has more than 50 genetic forms in North America, often initially presents itself in seedlings, but it can stay for the long haul, wreaking havoc from the beginning to the end of the growing season. Knowing what to look for and how to prevent the disease can help minimize damage in soybean fields.

What to look for: Scouting throughout the season can help for future years. University of Minnesota Extension recommends looking for the following symptoms at each stage of the season:
- Early season: Seedlings and plants at later vegetative stages that have infected stems will likely appear bruised with yellowing leaves.
- Mid- to late season: Brown lesions may start to appear on the roots as they begin to rot. Leaves will continue to yellow and wilt, staying attached to the plant even after it begins to die.
How to prevent it: Growers can get ahead of Phytophthora root rot by taking the following management steps:
- Increase drainage and avoid soil compaction to create a field environment that reduces the likelihood of saturated soils.
- Plant soybean varieties with built-in genetic tolerance. Phytophthora is more likely to affect fields that have had a history of the disease in the past.
- Maintain records of fields that have had a history of Phytophthora and evaluate the effectiveness of the resistant genes planted.

Protect Corn Now Before Gray Leaf Spot Strikes

SyngentaAgronomy — Fri, 09 Jun 2017 19:28:33 +0000

Gray leaf spot (GLS) has become one of the most yield-limiting diseases for corn in multiple regions across the U.S. GLS pathogens are known for overwintering in crop residue - it only takes a combination of warm and humid weather for GLS to spread and infect a new plant. When scouting, Purdue University advises growers to check corn leaves for small, pinpoint lesions surrounded by yellow halos. Further along in development, lesions become long, narrow and rectangular, and can vary from brown to gray in color. Although scouting is a crucial part of disease diagnosis, the incubation period for gray leaf spot can be 27 days or more, so crops can be infected for a long period of time before lesions appear. This can lead to significant, unexpected yield loss. Syngenta encourages growers to make proactive disease management decisions this season and treat corn fields before GLS hits to minimize the risk of damage and yield loss. This is the most effective way to avoid damage that could hinder photosynthesis. Syngenta recommends applying Trivapro^® fungicide for preventive and curative disease control to maximize yield and profit potential this season.

Mid-Season Tough Weed: Waterhemp

SyngentaAgronomy — Mon, 12 Jun 2017 17:16:38 +0000

In addition to soybean and corn seedlings, keep an eye out for one of the toughest weeds out there: waterhemp. While late-emerging waterhemp doesn’t pose as big of an immediate threat to yield as it does earlier in the season, it can deposit up to 1 million seeds in the soil bank, contributing to future problems. Identification

Absence of hair
Glossy and elongated leaves
Stem color varies from light green to dark red

After applying a pre-emergence herbicide, the next step is to apply a timely post-emergence herbicide with residual components to manage waterhemp before it reaches 4 inches. The University of Illinois reminds growers to use multiple effective modes of action on target weeds in a post-emergence application. Using the recommended rate of a post-emergence herbicide like Acuron^®, Acuron^® Flexi or Halex^® GT herbicides in corn, and Flexstar^® GT 3.5 herbicide in soybeans is an effective approach in managing waterhemp. Because waterhemp has developed resistance to many different herbicide classes, scout your fields throughout the season to determine the effectiveness of your herbicide applications. Also, consider complementing your herbicide program with mechanical control methods and/or hand removal to avoid waterhemp escapes from going to seed.

Early Insect Pressure May Spell Trouble for Delta Fields

SyngentaAgronomy — Mon, 12 Jun 2017 22:16:41 +0000

Extreme weather across the Mid-South may have growers focused on replanting and clean-up. To add to their woes, growers will need to be on alert for insects as entomologists are noticing heavier-than-expected insect pressure in some areas. This makes scouting and keeping a pulse on moth flights especially important to be able to stay ahead of leps later this summer. Integrated pest management is a comprehensive approach for controlling insects. Here are a few tips:

Scout on a regular schedule
Monitor moth flights
Observe field borders
Apply insecticides when needed

We suggest Besiege®, a broad spectrum insecticide that fights off destructive lepidopteran pests across a broad range of crops. To keep tabs on insects that may be invading fields, we also recommend signing up for state-specific updates via text message through our Pest Patrol program. University experts report on which pests they’re seeing in states across the South. Syngenta hereby disclaims liability for third-party websites.

Cotton Beware: Plant Bugs, Stink Bugs Preparing to Invade

SyngentaAgronomy — Mon, 12 Jun 2017 22:33:12 +0000

As flowering weed hosts begin to die down, watch for plant bugs to move into cotton fields. Stink bugs are another pest to monitor. Both insect pests have piercing, sucking mouthparts they use to penetrate cotton bolls and feed on seeds. This damages lint quality and can even cause bolls to abort. Stink bugs can also transmit disease pathogens that lead to boll rot. While these pests don’t pose as much of a threat to young cotton, they do require attention as cotton begins setting because of the damage they do to bolls. There are several methods to monitor presence of and damage from these pests, including sweep nets, drop cloths and visual inspection of bolls. Treatment thresholds vary across geographies, so it’s a good idea to connect with a local entomologist or consultant. If treatment is warranted, we recommend using an insecticide like Centric®. This foliar insecticide provides a rotational resistance management tool that helps manage pests, such as plant bugs and stink bugs, to help preserve cotton quality.

Focus on Weed Spectrum

SyngentaAgronomy — Tue, 13 Jun 2017 22:27:40 +0000

Herbicide resistance can cause pesky weeds to grow in your fields. Developing a management plan based on a field’s weed spectrum ensures weeds are controlled with the right herbicide so the soybean crop can capitalize on nutrients and moisture in the soil. Timing is also critical to maximizing control. A herbicide like Flexstar® GT 3.5 will help keep weeds out of soybean fields. Flexstar GT 3.5 is a post-emergence herbicide with two modes of action designed to control weeds that are resistant to glyphosate alone. In order to preserve the efficacy of the post-emergence treatment and prevent selection pressure, Flexstar GT 3.5 should be applied to weeds that are 2 to 4 inches tall.

Summer Brings Threat of Insect Pressure to Area Crops

SyngentaAgronomy — Tue, 13 Jun 2017 23:09:12 +0000

From tree fruits to vegetables to row crops, the East Coast features a multitude of crops, which means a variety of insect challenges. Regardless, there are common practices to monitor for insects as we move into summer months when these pests become a major concern. A few integrated pest management principles include:

Scouting to identify the presence and infestation level of insects: Each crop will have different recommendations for properly accomplishing this – from using sweep nets to drop cloths to pheromone traps.
Noting presence of beneficial insects: These good bugs can play a role in managing certain damaging insects, so it’s important to take note of any beneficials, such as lady bugs, green lacewing, minute pirate bug and assassin bug.
Identifying treatment thresholds: Your extension entomologist or crop consultant can help identify the infestation level that warrants an insecticide treatment.

When an insecticide treatment is called for, we recommend Besiege® insecticide to manage a broad spectrum of lepidopteran, sucking and chewing insects across a wide range of crops. It provides both rapid knockdown and long-lasting residual control using dual modes of action that deliver control through contact, ingestion and ovicidal activity.

Lowering Risk of Disease in Soybean and Corn

SyngentaAgronomy — Tue, 13 Jun 2017 23:16:41 +0000

As we head into summer, soybean and corn crops may face diseases such as northern corn leaf blight (NCLB), gray leaf spot (GLS) and Frogeye Leaf Spot (FLS). These diseases can be particularly destructive. NCLB

Yield losses may be has high as 30-50% if the disease becomes established before tasseling

GLS

Up to 50% yield loss

FLS

Up to 30% yield loss with extensive leaf blighting

In regions where the disease has been reported, yield losses ranged from 10-90%. When looking for a fungicide that can take care of these and a broad-spectrum of other diseases in corn and soybeans, we recommend Trivapro® fungicide. This harder-working, longer-lasting fungicide features three active ingredients that deliver residual disease control and crop enhancement benefits to help maximize yield potential.

It’s Time to Keep Insects out of Almond Orchards

SyngentaAgronomy — Tue, 13 Jun 2017 23:16:43 +0000

Insects pose significant threats to almond quality and yield. One of the keys to maximizing yield potential is minimizing the threat to your crop by sucking and chewing insects like navel orangeworm, peach twig borer and leaffooted plant bugs.

Damage from navel orangeworm ranges from larvae in the nutmeat, consumption of the nut, webbing and frass, and fungal infections. Proper sanitation and cleaning can prevent navel orangeworm in almonds, but insecticides should be used if pest invasion continues.
According to University of California Agriculture and Natural Resources, peach twig borers create shallow channels and surface grooves on the nutmeat.
Leaffooted plant bugs have historically moved to pistachios mid-June; however, an extended stay in almond crops is a possibility.

Protecting almond crops from these pests will prevent lower crop yields. To control navel orangeworm, peach twig borer and leaffooted plant bugs, we recommend using Besiege ®, a foliar insecticide providing both rapid knockdown and long-lasting residual control against sucking and chewing pests.

Keep Flea Beetles, Stink Bugs, Other Insects out of CA Tomatoes

SyngentaAgronomy — Tue, 13 Jun 2017 23:34:43 +0000

Recognizing which pests tomatoes are most vulnerable to at each stage of plant development is extremely important. Seedling tomatoes are especially vulnerable to flea beetles, while stink bugs do most of their damage to fruit. Lepidopteran pests can defoliate and interfere with photosynthesis. Flea beetles are common pests in tomato crops. Most damage occurs in fields previously planted with tomatoes, so it is best to rotate with a nonhost crop. Flea beetles typically appear at field borders in fields not previously planted with tomatoes, so careful scouting of field edges is important. Treatments should be considered when small holes are detected on leaves, transplants or seedlings. Stink bugs cause surface discoloration and decay. Early treatment will be most effective in protecting tomato crops from stink bugs, as newly hatched nymphs are the most easily controlled. Larvae from lepidopteran pests feed on the fruit and can cause significant damage to tomato crops. To help prevent these insects from infesting fields, Syngenta offers Besiege ® insecticide, which provides fast knockdown and controls a wide range of tomato insect pests.

Careful Scouting Crucial for Insect Management in Alfalfa

SyngentaAgronomy — Wed, 14 Jun 2017 00:00:16 +0000

Successful alfalfa production can be considerably hindered by various pest threats. As such, continuous monitoring and scouting are essential to effective insect management. Alfalfa growers in the Pacific Southwest need to have an insect management plan in place before pests reach damaging levels. Pests to watch: Be on the lookout in June for looper and armyworms. If populations are detected, consider early harvesting to prevent yield loss. If early harvesting is not an option, treat alfalfa with an insecticide. Aphids can severely reduce yields and call for weekly monitoring. If aphids pose a threat to alfalfa, insecticides should be applied. Besiege® insecticide provides consistent performance under a variety of conditions. With active ingredients chlorantraniliprole and lambda-cyhalothrin, Besiege provides fast knockdown and long-lasting control of a wide range of insect pests including weevils.

CA Grape Disease Control Made More Complex with Winter Rains

SyngentaAgronomy — Wed, 14 Jun 2017 00:02:28 +0000

Heavy powdery mildew last year and rains this year suggest more disease pressure from powdery mildew can be expected in this season’s grapes. According to University of California Integrated Pest Management Program, powdery mildew can survive from season to season, in rain and humid weather, and causes splitting of the fruit and reduced growth for grape crops. Botrytis bunch rot is another disease likely to be problematic in California due to the heavy winter rains. Humidity in the summer months only adds to the likelihood of this disease impacting fields. Once infected, grapes split and spread spores to surrounding berries. Thorough fungicide coverage before rain can help prevent infections. Syngenta offers Inspire Super® fungicide to aid in powdery mildew and Botrytis management. Featuring a combination of two fungicides for resistance management, it provides excellent rainfastness and flexible application options.

Manage Disease to Help Produce Tomato Fruit

SyngentaAgronomy — Wed, 14 Jun 2017 15:13:41 +0000

Diseases like powdery mildew and black mold impact tomato crops by destroying leaf tissue and reducing energy that could otherwise be used in fruit development. In addition, the loss of foliage leaves fruit more susceptible to sun damage. Fungicide applications can help control disease and can be applied preventatively or early on in the infection. According to University of California Agriculture and Natural Resources, tomato crops can have black mold 4 to 5 days after a period of heavy rain and humidity. Tomatoes should be harvested once they have ripened because delay can increase the likelihood of black mold. A fungicide treatment, Quadris Top® fungicide, should be used to control disease and is especially important in this rainy year. Through a combination of azoxystrobin and difenoconazole, Quadris Top helps control key tomato diseases.

Managing Fungi and Disease can be the Key to Healthy Vegetable Crops

SyngentaAgronomy — Wed, 14 Jun 2017 15:25:57 +0000

Managing fungi and diseases across vegetable crops is a continuous challenge. Blights, mildews and molds are especially destructive to leaf tissue and crop quality and are common in the Western region.

Broccoli, cauliflower and other vegetables are susceptible to downy mildew.
Late blight hosts include tomatoes and potatoes and cause lesions on leaves and stems that expand and become darker in color. Spores may be observed on the leaves and stems, as well. Affected fruit remains firm or can decay.
Blue mold appears on vegetables like onion and garlic during harvesting. Water-soaked areas appear on the surface and green to blue-green powdery mold is visible. Invasion usually occurs through crop wounds and insect damage.

These fungi and diseases can all be controlled using Revus® fungicide. Revus is an excellent rotation partner for oomycete management. The fungicide provides rainfastness and long-lasting residual control. Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Keep Phytophthora out of Citrus Groves

SyngentaAgronomy — Wed, 14 Jun 2017 20:39:23 +0000

Phytophthora is a particularly damaging pathogen in citrus groves. It attacks root systems, trunks and fruit, causing foliage to yellow, leaves to fall, twigs to die, and fruit size and yield to decrease. Just like many other disease pathogens, early detection can help protect citrus trees. Dig up roots to test the tissue for the presence of a specific Phytopthora protein. If it is present, there are several cultural methods to help manage the pathogen:

Irrigate early or midday
Avoid overwatering
Provide adequate soil drainage

In addition, an application of Ridomil Gold® SL fungicide can deliver improved stand, root health and crop vigor to help maximize return on investment.

Amaranth Family Leads Top Weed Concerns Among Southeast Growers

SyngentaAgronomy — Thu, 15 Jun 2017 21:00:48 +0000

The Amaranth family, laying claim to nearly 75 different species, is a force to be reckoned with. Palmer amaranth and waterhemp rank among the top 5 most troublesome weeds, according to a survey by the Weed Science Society of America. Southeast growers are all too familiar with the challenges these weeds pose in their soybean and cotton crops, in particular. As small-seeded, annual plants, amaranth species grow quickly in open areas with full sun and undisturbed soils, producing from tens of thousands to hundreds of thousands of seeds per plant.

Due to rapid growth, aggressive competition, prolific seed production and germination throughout the season, Palmer amaranth, also known as pigweed, can reduce crop production and even hinder harvesting efforts.
Waterhemp can produce more than 1 million seeds per plant. Just a few untreated weeds in a field can lead to a major infestation. With a germination period that lasts several months, waterhemp can grow in a variety of climates, as evidenced by its presence in 40 states. Waterhemp is identified by a lack of hair on its stems and leaves that give the weed a bright, glossy appearance.

The most effective control can be obtained when post-emergence herbicides like Flexstar® GT 3.5 are applied before weeds reach 4 inches tall. Using two different modes of action and containing Isolink® II Technology, Flexstar GT 3.5 optimizes the systematic activity of glyphosate and contact activity of fomesafen to help protect yield potential.

Watch for Cotton Bollworm, Stink Bugs, Plant Bugs in TX Cotton

SyngentaAgronomy — Thu, 15 Jun 2017 21:05:20 +0000

Reports over the past month on Pest Patrol from Texas researchers Dr. David Kerns and Mr. Stephen Biles indicate cotton bollworm, stink bugs and plant bugs will soon become pests of concern for Texas cotton growers. Dr. Kerns reported last month that corn earworm is present in corn, so it’s important to keep an eye out for the pest in cotton as well. Mr. Biles noted that cotton fleahoppers remain a concern in cotton up to bloom. After bloom, bollworms, stink bugs and plant bugs become a primary concern. He advises the following thresholds for the Coastal Bend region:

Bollworm populations of 5,000-10,000/A when scouting bolls
Stink bugs and plant bug populations of more than 20% in 1” bolls

Syngenta recommends Besiege® insecticide to control lepidopteran pests, stink bugs and plant bugs, as well as cotton fleahoppers. This broad-spectrum insecticide uses contact, ingestion, and ovicidal action to control lepidopteran pests. To keep tabs on insects that may be invading fields, we also recommend signing up for state-specific updates via text message through our Pest Patrol program. University experts like Dr. Kerns and Mr. Biles report on which pests they’re seeing in states across the South. Syngenta hereby disclaims liability for third-party websites.

Watch for Blight and Leaf Spot Diseases in Corn Across Southern Great Plains

SyngentaAgronomy — Thu, 15 Jun 2017 21:10:31 +0000

With areas of the Southern Great Plains experiencing dramatic weather events, we must remain vigilant in protecting corn from additional stress by monitoring for potential disease infections, such as Northern corn leaf blight (NCLB) and gray leaf spot (GLS). Some common identifiers for NCLB and GLS include: NCLB

Gray and elliptical shaped lesions that gradually turn tan

GLS

Small, brown or tan spots surrounded by a yellow halo
Elongated, rectangular shaped spots
Fuzzy, gray fungal spores on the underside of leaves

We recommend using a fungicide, such as Trivapro®, to control these and other diseases. With three active ingredients Trivapro delivers harder-working and longer-lasting control of key diseases and provides crop enhancement benefits to protect crops from multiple sources of stress. Trivapro allows the plant to maximize grain-fill by putting more energy toward producing yield instead of fighting disease, and results in stronger stalks, healthier roots, and fuller ears.

Stripe Rust Continues to Threaten Wheat

SyngentaAgronomy — Thu, 15 Jun 2017 21:10:26 +0000

The stripe rust that threatened our winter wheat will continue to affect our spring wheat in the Pacific Northwest. Characterized by the yellow orange pustules located linearly between leaf veins, stripe rust survives between seasons and can be spread by wind. Increase in water loss and decrease in green leaf tissue due to infections may reduce wheat yield. Responsible for past wheat epidemics in the Pacific Northwest, stripe rust can be a real threat to wheat growers’ profitability. Growers can take a proactive approach to controlling stripe rust this spring by scouting their fields early and often. We also suggest applying a foliar fungicide. Compared with other programs, Trivapro® fungicide provided superior control of stripe rust in winter wheat and will provide the same harder working, longer lasting protection in spring wheat. Trivapro helped boost yields on average by 13 bu/A and also offers:

Long-lasting preventive and curative disease control
Improved crop enhancement

Manage Disease and Protect Your Potatoes This Summer

SyngentaAgronomy — Thu, 15 Jun 2017 21:15:06 +0000

Prevalent in Idaho and the Pacific Northwest, white mold develops in areas with dense canopy growth and moist conditions. Lesions begin to form between the stem and branches, 2 to 3 weeks after row closure, and white cottony growth spreads. Foliage wilt, bacterial stem rot and plant death result from white mold. Crop rotation with nonhosts, managing canopy growth and density, and proper irrigation reduce the risk of white mold affecting potato crops. Omega® fungicide is an additional tool for white mold management in potato crops. The fungicide is a flexible option for growers that offers a multi-site mode of action to attack pathogens, low use rates, various application methods and quick rainfastness.

Take Control of Colorado Potato Beetles in Potatoes

SyngentaAgronomy — Thu, 15 Jun 2017 21:20:12 +0000

The Colorado potato beetle can cause significant losses in potato crops. The Pacific Northwest Pest Management Handbooks provide tips to help potato growers manage Colorado potato beetle populations. Due to the pests’ tendency to overwinter near places where potatoes were planted in the year prior, growers can generally predict the emergence of the Colorado potato beetle with the aid of degree day models. Because the newly emerged beetles are not heavy feeders, it is best to apply insecticide treatments at the first and second instar stages of the first generation. Good crop rotation practices are also an important management method. For excellent control of Colorado Potato beetle and other harmful potato pests, Syngenta recommends Minecto® Pro insecticide, a broad-spectrum, foliar insecticide that harnesses the power of two complementary active ingredients.

Identify Rust Early to Protect Corn Yield

SyngentaAgronomy — Wed, 14 Jun 2017 22:32:35 +0000

Every season, rust appears in corn fields throughout the South and, in more recent years, the Midwest. Although rusts don’t survive Midwest winters, pathogens typically travel northward from Southern states each spring and summer. Common rust does not frequently cause significant yield loss, but according to Purdue University, Southern rust has become more significant in Southern states, routinely reducing yields as much as 25 bu/A on susceptible hybrids that do not receive a fungicide application. In the Midwest, Southern rust has the greatest potential to damage corn fields if it spreads at a critical point in the growing season. It’s important for growers to be able to identify the difference between these two types of rust in order to best determine whether a treatment plan is necessary. Identifiers: Southern rust:

Pustules on the upper leaves
Orange to light brown and round
Densely packed on the leaf surface
Can cause significant yield loss in Southern states and has become more problematic in the Midwest

Common rust:

Pustules on upper and lower leaf surfaces
Reddish and elongated
Scattered on the leaf surfaces
Typically does not lead to significant yield loss

Growers should frequently check the Integrated Pest Management Southern corn rust tracker to stay on top of this disease’s path. If rust spreads to neighboring regions, Syngenta advises growers to treat proactively before rust hits their county. Syngenta offers Trivapro^® fungicide for best-in-class preventive and curative control of rust and other difficult-to-control disease. Trivapro also delivers crop enhancement benefits that help maximize grain fill, produce stronger stalks and reduce lodging.

Strobilurin-Resistant Frogeye Leaf Spot Threatens Late-Planted Soybeans

SyngentaAgronomy — Fri, 16 Jun 2017 15:18:41 +0000

With heavy spring rains, many growers had no choice but to plant their soybeans late this season. The Ohio State University research shows later planted soybeans have a higher chance of being infected earlier in the season with frogeye leaf spot (FELS) and could experience yield losses of 5 bushels per acre (bu/A) if infected before the R3 growth stage. Late planted soybeans have an increased risk of damage from FELS, and especially strobilurin-resistant FELS – a disease that has been confirmed in recent years in 11 different states across the South and Midwest. Strobilurin-resistant FELS is often difficult to control. Syngenta advises growers to treat for strobilurin-resistant FELS proactively with multiple modes of action, particularly in fields that have had confirmations of this disease in the past. Syngenta offers Quadris Top^® SBX fungicide, which contains difenoconazole for preventive and curative disease control and azoxystrobin for crop enhancement benefits, promoting root strength and pod fill.

Pest Alert: Asian Citrus Psyllid Control in Texas

SyngentaAgronomy — Tue, 20 Jun 2017 23:07:29 +0000

It’s a tiny insect, but its potential for damage is so great that citrus in entire counties and states are quarantined. The pest is Asian citrus psyllid, or ACP, and, aside from the damage ACP can do to new growth, such as burned tips and twisted leaves, it can carry Huanglongbing (HLB) disease. According to the USDA, HLB, also known as yellow shoot or citrus greening disease, is one of the most serious citrus plant diseases in the world. In states like Florida, most mature trees are assumed to be infected with HLB, but Texas citrus is still considered largely uninfected. For growers in this state, controlling the pest that transmits the disease is key to stopping its spread. Scouting for ACP early and often and treating appropriately can help prevent infestation and help curtail pest populations. The University of Florida Extension provides multiple methods for scouting ACP. When scouting, look for winged adult insects that feed from a vertical position with black-tipped wings rising into the air, as well as flat, yellow-bodied nymphs that leave behind white honeydew and distorted leaves as they feed. If you suspect that trees have been fed upon by ACP, quickly quarantine the trees to prevent the spread of possible HLB infection. In order to preserve fruit quality, do not mix fruit harvested from the presumably infected tree with that of uninfected trees. Avoid runoff from irrigation that passes from the presumably infected to uninfected trees. Controlling its vector, ACP, is a primary tactic in managing HLB and slowing its spread. Minecto® Pro insecticide, the premix formulation of cyantraniliprole and abamectin, offers long-lasting residual control of a broad-spectrum of key citrus pests, including ACP, citrus rust mites and citrus leafminers. ©2017 Syngenta.

Establish a Pollinator Habitat on Your Farm

SyngentaAgronomy — Wed, 21 Jun 2017 16:43:38 +0000

June 19-25 marks National Pollinator Week, a great time to consider growing a pollinator habitat on your property and start planning ahead to planting wildflower seeds this fall. Converting unused or marginal land to pollinator habitats can have several benefits, such as reducing soil erosion and helping to protect valuable water resources. Interested in establishing a pollinator habitat on your property? Here are some tips to help you get started and maintain your site.

Site Selection

When picking a site, think about the variables that will help it be successful. For example, selecting a site on the upside of prevailing winds will help protect the area from potential pesticide drift. Locations with full sun are best for wildflowers and grasses to thrive, and locations beside or within natural areas are best for bees and butterflies.

Seed Mixture Selection

You can have the best-prepared site in the world, but if you don’t use the right seed mixture for your site, you will not achieve the desired result. Use native plant seeds when possible, but when cost and/or availability don’t allow for that, select adapted species that are non-invasive and rich in nectar and pollen. Wildflower mixtures should include plants that flower from spring to fall, to provide a long season of pollen and nectar for pollinators.

Site Establishment

Proper site preparation, including clearing the ground and minimizing the presence of weeds and other plants, is critical for good results. Small areas can be seeded by hand or with the use of a drop or cyclone spreader. Seeds should be raked in lightly or dragged before firming with a cultipacker to maximize seed-to-soil contact. Avoid burying your seed. If seeds are planted too deeply, the plants will emerge poorly.

Site Maintenance

Without control of fast-growing annual weeds, plant seedlings can quickly be covered by a canopy of weeds. Mowing at a height of at least 4 inches, whenever the weeds reach 12‒18 inches, will effectively control weeds in the first growing season without harming the slower-growing wildflowers. After emergence of desired plants, weeds can also be pulled by hand, spot-sprayed with a non-selective, non-residual herbicide, or cut off with a weed eater. If no native grasses have been seeded, a selective grass herbicide may be used. When the use of herbicides is indicated, check with your County or State Extension Service or local Syngenta representative for recommendations. Patience is needed – it will take 2‒3 years for the root systems of new perennial plants to crowd out other plants that have grown there in the past. But over time, your pollinator habitat will require less maintenance than your crops.

Match Roots, Seeds and Soils to Increase Corn Yield

SyngentaAgronomy — Fri, 23 Jun 2017 19:01:39 +0000

What’s going on beneath the soil often dictates how a crop looks above ground. In corn fields, that translates directly to root quality. When a hybrid’s root type is paired properly with soil type, the two agronomic characteristics team up to help maximize yields. Although corn roots typically grow 2 feet to 7 feet deep – generally however deep it takes to find moisture – roots are traditionally characterized into 1 of 3 classes, one of which is more fitting for your field:

Fibrous (pictured left above): Identified by shallower feeder roots and finer hairs, these roots are ideal for coarse soils because they absorb more nutrients and soil.
Penetrating (pictured right above): Classified by deeper roots that push further down into the soil, these structures are ideal for compact layers.
Modified (pictured center above): Labelled as a combination of fibrous and penetrating root types, these structures contain finer hairs that dig deeper into the soil.

When corn roots develop their full yield potential, increased branching enables plants to digest water and nutrients more efficiently. Keep in mind a bigger root system doesn’t necessarily mean a better root system. This is because larger roots require greater resources to maintain, which in turn takes energy away from yield production. To learn more about matching seed and soil type to maximize yield, watch Product Development Agronomist Doug Kirkbride’s roots demonstration here.

Scout Early for Cotton Pests to Manage Infestations

SyngentaAgronomy — Tue, 27 Jun 2017 22:57:31 +0000

A recent article in AgFax underscores the importance of scouting cotton for plant bugs from the first square until the last harvestable boll. When scouting, be sure to check along the edges and through the middle of your field. Plant bugs can distribute unevenly and may move through the day, so thoroughly checking plants throughout the field is necessary. Data shows that leaving plant bugs untreated hurts yield, so when they reach treatable levels insecticide applications need to begin early and may be needed multiple times. At this point in the season, a full-labelled rate of a neonicotinoid, such as Centric® foliar insecticide, is a good option. Using neonicotinoids initially allows for rotation to pyrethroids later in the season, which is a great way to practice insecticide resistance management.

If You Aren’t Ready for Downy Mildew, Get Ready

SyngentaAgronomy — Wed, 28 Jun 2017 23:23:25 +0000

Downy mildew has been reported in southern Ontario and MSU Extension is letting growers know that if they haven’t already, it’s time to prepare for the disease. Caused by Oomycete parasites, downy mildew gets its name from the fluffy sporulation that usually appears on the bottom of infected leaves as the pathogen completes its disease cycle. The spores can germinate and spread the disease to healthy plant tissues. The initial symptoms are chlorotic lesions, which later become brown and necrotic. Cool, wet conditions with high humidity favor disease development. Though downy mildew affects many crops, cucurbits are particularly susceptible. Syngenta recommends preventive applications of Orondis® Opti fungicide for excellent control of downy mildew and as a resistance management tool.

Five Tips for Integrated SCN Management

SyngentaAgronomy — Fri, 30 Jun 2017 20:01:43 +0000

During our Seedcare™ Showcase at the Slater, IA Grow More™ Experience site this month, we advised that growers use an integrated management program to protect crops. Here are 5 management recommendations that together can help prevent SCN infestations:

Sample soils: Depending on the previously planted crops, growers may want to consider sampling their soils. If planting soybeans followed by soybeans, sampling is best done immediately following harvest; however, if a grower is planting soybeans following a non-host crop such as corn or alfalfa, they can wait until after fall tillage.
Plant SCN-resistant varieties: Growers should consider planting NK® Soybeans with built-in resistance to SCN for added protection.
Use a seed-applied nematicide: Clariva Complete Beans® seed treatment, a combination of separately registered products, provides season-long, lethal activity against SCN and complements resistant varieties.
Non-host crop rotation: Rotating between soybeans and non-host crops can also reduce the likelihood of SCN for future seasons.

Get Ahead of Southern Rust

SyngentaAgronomy — Fri, 30 Jun 2017 20:34:27 +0000

Although not yet a problem, Syngenta agronomists recommend corn growers in eastern IA to consider the likelihood of Southern rust this season, especially if the heat continues. The pathogen, which is currently showing up in the southern part of the country, has the ability to travel long distances in the wind and spread in corn fields. Agronomists from the Slater, IA Grow More™ Experience site are keeping an eye out for the disease on their trial acres, and are advising growers to take precautions to avoid yield loss down the road:

Scouting corn fields: Getting into the fields and scouting is one of the most effective ways to watch out for the disease. Southern rust will cause symptoms such as pustules on the upper leaves, pathogens densely packed on the leaf surface and leaves to turn orange/light brown.
Apply a fungicide: Trivapro® fungicide provides preventive and curative control of Southern rust. Not only does Trivapro provide disease control, but it also delivers crop enhancement benefits including protecting green leaf tissue to maximize grain fill and improving stalk quality and strength for reduced lodging which leads to higher yields and return on investment.

Growers can check the Integrated Pest Management website to see where Southern rust is being spotted across the country.

First There was Rain, Then There Were Weeds

SyngentaAgronomy — Mon, 03 Jul 2017 19:31:44 +0000

For one grower in Missouri, the 2017 growing season began with a bumpy start. Having used competitive products for years, his field was experiencing high grass pressure so he made the switch to Acuron® corn herbicide. Since Acuron provides the most consistent control, this grower anticipated an easier growing season. What the grower did not expect was smooth crabgrass appearing 21 days after Acuron had been applied. Two Syngenta reps assessed the situation in the field and quickly found the problem: the weather was inconsistent, so there hadn’t been an activating rain event for two weeks after the product had been applied. Moisture is critical for any herbicide to activate. And since Acuron wasn’t able to be activated with rainfall, it couldn’t do its job. But what it lacked in the beginning, it more than made up for a week later when it rained 3 inches. From that point on, the grower not only observed the unique, broad-spectrum control Acuron has to offer, but he also got to witness it reaching-back to destroy all pre-existing weeds. As you can see in the pictures below, Acuron was quickly able to eliminate the grower’s crabgrass infestation. From left to right: Smooth crabgrass emerged before Acuron activation. After Acuron activation, crabgrass numbers start to diminish. Acuron, fully activated, reached back and killed off remaining crabgrass. The season may have had a bumpy start, but it is back on track now. This grower, and his 3,000+ acres, is looking forward to a successful year with Acuron.

Thirty-Year Battle Won with Acuron

SyngentaAgronomy — Wed, 05 Jul 2017 22:23:01 +0000

Minndeman’s clean field after using Acuron. Wisconsin: For 30 years, Aric Minndeman and his family have run their family farm. And for much of that time, they have fought the same tough weed – the giant ragweed. Growers across the country can relate to Minndeman’s problem. Giant ragweed is one of the most common weeds in the U.S., and one of the most troublesome. With its rapid growth rate, both in size and in numbers, and its yield robbing potential, Minndeman wanted giant ragweed gone. So in 2016, he turned to Acuron® corn herbicide. Minndeman used Acuron last year in hopes that a one-pass treatment on his corn would do the trick. By switching to Acuron, Minndeman was able to rid his land of the persistent weed. The Acuron formulation is specifically designed to fight tough weeds like the giant ragweed. With four active ingredients and three effective modes of action, Acuron delivers the most consistent weed control on the market. Additionally, the multi-targeted approach offers built-in corn weed resistance management and season-long residual control. For growers like Minndeman, this means higher yields and greater profitability. Minndeman explains that for 30 years it was a challenge to find a product that offered residual control all season. He’s really happy with how Acuron had performed last year and looks forward to another exciting season with Acuron this year.

New Experimental Fungicide Protects Against Powdery Mildew

SyngentaAgronomy — Thu, 06 Jul 2017 20:16:57 +0000

At our wine grape fungicide trial in Hickman, CA, our team is evaluating the efficacy of our fungicides against powdery mildew. Because chardonnay grapes are so susceptible to disease, this grape variety was chosen for the trial. Powdery mildew is an early to mid-season disease that does its damage to both the leaves and the grapes. We’ve already begun to see it spread on the untreated areas, as you can see in the photo above. It begins to damage the leaves, affecting its ability to photosynthesize. From there, the grape clusters will have trouble fully developing, affecting yield and flavor. Getting in early applications of fungicide will help to greatly reduce the risk of powdery mildew. At Hickman, we are testing the efficacy of a new experimental fungicide, followed by an application of a fungicide with a different FRAC group (see photo above). We have set up 2 time-lapse cameras in the field, one on the untreated and the other on the treated so we can see how this new application protects against powdery mildew over the course of the growing season. Stay tuned for more information on the progression of powdery mildew in this trial and the continued protection against diseases throughout the season, such as botrytis.

Use Multiple, Effective Modes of Action to Control Waterhemp

SyngentaAgronomy — Fri, 07 Jul 2017 15:19:08 +0000

Caption: Pana, IL: Clean Acuron® corn herbicide rows (left) vs. atrazine-only rows with heavy waterhemp pressure (right) 45 days after application on June 13, 2017. Waterhemp is a difficult-to-control weed throughout the Midwest. Several factors that make it problematic are its immense seed production and ease of mobility. A single waterhemp produces up to 1 million seeds, and its pollen travels up to one-half mile. Left untreated, waterhemp can easily overtake a field and deposit millions of seeds into the weed seed bank. At the Pana, IL, Grow More Experience site, a corn herbicide trial demonstrated the value of using herbicides with multiple, effective modes of action to control difficult weeds like waterhemp. One side of a small demo plot received a treatment of Acuron at 3 qt/A and 1 lb/A atrazine while the other half was only treated with 1 lb/A atrazine. After 45 days, the atrazine-only side showed significant waterhemp pressure while the Acuron-treated side remained clean because Acuron contains three effective modes of action. Contact your Syngenta representative to visit the Pana, IL, Grow More Experience site in July or August. July is the optimal time to view the site’s herbicide demonstrations while August is the best timing for the fungicide demonstrations.

Choose Resistant Varieties to Reduce Fusarium Wilt in Lettuce

SyngentaAgronomy — Fri, 07 Jul 2017 18:27:45 +0000

Fusarium wilt disease of lettuce (FWOL) is a growing threat to lettuce growers’ crops. A soil-borne pathogen, FWOL can ruin crisphead (iceberg) and romaine lettuces, causing plants to collapse, wilt or die. Fusarium wilt causes significant economic impact across lettuce-growing regions. According to a recent article in Western FarmPress, choosing varieties with some resistance is one way growers can manage this disease. Many other soil borne lettuce diseases are treatable, but Fusarium wilt is not. However, there are strategies to prevent and manage the disease, including being aware of field history, planting pathogen-free seed and selecting varieties with the most resistance. Syngenta is committed to breeding resistant varieties in Fusarium wilt and other key lettuce diseases. In romaine, Syngenta recommends planting Duquesne variety lettuce.

Protect Corn Yields from Southern Rust Now

SyngentaAgronomy — Mon, 10 Jul 2017 23:03:24 +0000

Last year Southern corn rust effected 11 different corn-growing states. This year, Southern rust has already been confirmed in Arkansas, Mississippi, Texas, Alabama, Florida and Georgia. Under favorable weather conditions, Southern rust has been known to reduce yields up to 25 bu/A on susceptible hybrids that do not receive a fungicide application. According to North Carolina State University, the disease can be especially detrimental to late-planted corn. Since this year’s wet spring delayed planting for many corn-growers nationwide and tropical storms are already impacting the South, there is potential for Southern rust to spread to the Midwest this season. Growers should stay informed about Southern rust’s path and can check the Integrated Pest Management tracker for updates. To prevent the yield-reducing effects of Southern rust, Syngenta advises growers to treat their corn at the R1 growth stage before rust hits their county. Syngenta offers Trivapro^® fungicide for harder-working, longer-lasting preventive and curative control of rust and other difficult-to-control diseases. Trivapro also delivers plant health benefits that help maximize grain fill and produce stronger stalks for reduced lodging and volunteer corn plants, resulting in maximum return on investment.

Scout Soybeans Now for Kudzu Bugs

SyngentaAgronomy — Wed, 12 Jul 2017 01:48:21 +0000

Jeremy Greene, entomologist at Clemson University, reports that nearly every soybean field he’s scouted in South Carolina has kudzu bugs. He recommends growers throughout the South actively scout and those in the Midwest begin monitoring for this pest. Kudzu bugs can contribute to up to 75% yield loss, according to the University of North Carolina, so it is important for growers to be extremely vigilant in scouting efforts in order to save soybean yields and profit this year. Greene is encouraging growers throughout the South to utilize a sweep net before soybeans begin to bloom, to determine whether or not they are causing damage and reproducing. Kudzu bug scouting tips:

Round bodies
Dark green with brown specs
Plate on the center of their backs

Should kudzu bugs reach local thresholds, Syngenta recommends Endigo^® ZC insecticide, a proven solution to prevent soybean damage from a wide range of pests for higher yield potential.

Don’t Underestimate Corn Rootworm

SyngentaAgronomy — Thu, 13 Jul 2017 20:22:16 +0000

Photo caption: CRW larvae on corn roots You may have noticed lower corn rootworm (CRW) pressure in recent years, but CRW pressures can vary from year to year and location to location. This resilient pest is highly adaptable and can wreak havoc even when least expected. Root damage from CRW is not evident until late in the season, often when it’s too late to fight the pest. If you’re thinking, “Why are you telling me this now when it’s too late to use an insecticide?”, it’s because you can take action this season to help maximize next year’s crop. How? It’s simple. This summer, monitor and document your insect pressure. Where you have adult corn rootworm beetles will be a good indicator for pressure next year since the beetles will likely go into the ground in that field to lay their larvae. This information will help you determine your management plan for next season. Using a robust soil-applied corn insecticide is an effective way to consistently minimize the risk of CRW damage from season to season. Force® Evo, a new liquid corn insecticide that will be available for the 2018 season, is designed for growers looking for performance year after year. Containing the trusted active ingredient, tefluthrin, Force Evo consistently outperforms other insecticides for control of CRW and other early-season pests, leading to improved root growth, better nutrient uptake and improved yields. When used on top of CRW traits, trials show Force brands deliver an average yield increase of 10 bu/A. And even in the absence of CRW, Force brands help increase yield because early-season pests like wireworms, white grubs and seedcorn maggots can cause more destruction than meets the eye. Bottom line, Force Evo is a risk management decision for peace of mind on every acre.

Wheat Harvest: A Series of Solutions

SyngentaAgronomy — Fri, 14 Jul 2017 20:20:30 +0000

Knowledge is a powerful tool and the more you know, the more wheat you can grow. In the frenzy of harvest, it’s easy to overlook clues that will help take the guesswork out of next season’s management. In the first of a 3 part series, we share some tips to keep in mind this wheat harvest: Scouting Scouting arms you with the information you need to identify the right herbicide, fungicide and seed treatment inputs for your wheat fields next year – whether that’s confirming that what you’re using now is working or deciding it’s time for a change. Fall is the best time to scout for, and manage, winter annual weeds such as downy brome, tansy mustard and absinthe wormwood. You should also keep an eye out for Fusarium head scab and other diseases. If disease severity is higher than expected, consider a seed treatment tailored to the diseases present and/or apply a fungicide sooner. Last, but certainly not least, check for insect pressure. Yield‐robbing damage from diseases and pests, like wireworm, can be prevented with the right seed treatment. Not all treatments are created equal. Make sure to check the active ingredient load when comparing products.

Wheat Harvest: The Next Step in Solution Management

SyngentaAgronomy — Mon, 17 Jul 2017 19:53:20 +0000

Knowledge is a powerful tool and the more you know, the more wheat you can grow. Scouting during harvest is a smart way to set you up for future success in wheat, or any crop for that matter. In part 2 of our 3 part series, here are some weed management tips to keep in mind during wheat harvest: Weed Escapes When weeds compete with crops, yield can suffer dramatically. Weeds negatively impact yield potential and quality by competing with wheat crops for nutrient uptake and water efficiency. Running a combine through weedy fields increases the risk of spreading weed seeds into previously clean fields. Take note of weed species that escape herbicide applications and reference them when considering herbicide inputs for 2018. If you see signs of weed pressure, it may be time to explore other grass or broadleaf herbicides than can control tough weeds your current product may be missing. It’s important to target difficult‐to‐control weeds, like kochia, and herbicide‐resistant species with multiple, effective modes of action. When faced with weeds, Syngenta recommends Talinor™ herbicide, which provides quicker, more efficient knockdown of tough broadleaf weeds.

Now's Not the Time to Relax About Downy Mildew

SyngentaAgronomy — Tue, 18 Jul 2017 21:02:07 +0000

Plenty of heat and rain in southeast Michigan has set the stage for various crop diseases. MSU Extension is reminding growers that this type of weather highlights the importance of preventative fungicide applications, even as it makes maintaining spray schedules difficult. MSU Extension also points out that while cucumber harvest is already underway and reports indicate a good crop, a confirmation of mature downy mildew in Monroe Country suggests now is not the time to neglect your fungicide program or lessen your vigilance for the disease. Syngenta recommends preventive applications of Orondis® Opti fungicide for excellent control of downy mildew and as a resistance management tool. Cucumber leaf showing symptoms of downy mildew.

Wheat Harvest: The Third Solution to Keep in Mind

SyngentaAgronomy — Tue, 18 Jul 2017 20:45:49 +0000

Knowledge is a powerful tool and the more you know, the more wheat you can grow. Checking plants for signs of physical damage can provide information on what’s happening beneath the soil. In the final post of our 3 part series, we suggest careful examination this wheat harvest season. Plant Physiology What you see above ground while scouting can provide clues about what was happening below ground during the season. If you notice the crop has less developed foliage, delayed heading, or reduced stand, you should consider using a seed treatment next season that offers comprehensive disease and insect protection to protect roots. Root health is critical for wheat plants to achieve their maximum yield potential because strong, healthy roots establish excellent plant stand and penetrate deeper into the soil to ensure maximum water and nutrient uptake in dry or wet conditions. Studies show a robust fungicide seed treatment can yield four bushels higher than a base fungicide seed treatment. When considering seed treatments, make sure to check the active ingredient load when comparing products. Ask questions like, “Has the seed treatment been tested for compatibility?” and “Is there agronomic data or seed safety data on your rates of the active ingredients that you can show me?” Syngenta recommends CruiserMaxx^® Vibrance^® Cereals, a seed treatment product for protection against damage from certain insects and diseases of cereals.

Stay On Top of CRW With a Proactive Management Strategy

SyngentaAgronomy — Wed, 19 Jul 2017 19:28:02 +0000

With corn rootworm pressure (CRW) varying from year to year, it can appear when least expected. Even though pressure has been lower in recent years, CRW tends to bounce back. Some CRW populations can lay dormant for nearly two years waiting for corn to return to the field. With the unpredictable nature of CRW, it is important for you to be observant. There are no instant solutions for managing CRW, so it's important to prepare for a possible outbreak prior to planting with a combination of effective, powerful traits and a sound multi-year management strategy. When working with a field that has experienced low levels of CRW pressure at any time in the past, it's likely that in any given season, it will experience that pressure again. For a field with a history of low corn rootworm pressure, Syngenta recommends a trait stack with 1 or 2 modes of action for CRW control or a soil insecticide. Consider trait stacks with dual modes of action like Agrisure® 3122 E-Z Refuge®, Agrisure Duracade® 5122 E-Z Refuge® or Agrisure Duracade® 5222 E-Z Refuge®. For those interested in using a single CRW trait stack, Agrisure® 3000GT or Agrisure Viptera® 3111 are 2 available choices. For a field that has experienced high corn rootworm pressure in the past, if crop rotation is not an option, consider a management program that includes a trait stack with one or two modes of action against CRW with a soil- or foliar-applied insecticide as needed for additional control.

The Branded Fungicides Advantage

SyngentaAgronomy — Wed, 19 Jul 2017 20:03:31 +0000

You may be tempted to treat your soybean fields with a generic fungicide versus a name-brand product to save on input costs. While the cost is worth considering, return on investment is the more important factor of the equation. What you may not realize is that many generic fungicides have slightly different formulations and can sometimes be less concentrated than name-brands, which makes all the difference in the product’s efficacy and impact on yield. Researchers with the University of Nebraska highlight some of the potential benefits you may receive from using a brand-name fungicide over a generic:

Quality of the product
Efficacy of the product
Dealer and manufacturer service
Ease of mixing
Product confidence

My experience in developing fungicides has taught me that formulation chemistry is both a science and an art, and Syngenta does it better than anybody else. Here’s what I mean:

Most active ingredients don’t like water. So we can add a surfactant that makes them like water better.
Then they go to the bottom (still not good). So we add suspension agents to keep the active ingredients distributed in the mix.
Water freezes and formulations have water so we have to add antifreezes.
Bacteria like to eat fungicidal active ingredients so we add anti-microbials.
Formulations with all these things added tend to foam, so we add anti-foams.
What happens when it rains after you apply a generic fungicide? They wash off. That is why we build formulations that have better rain tenacity and disperse more effectively across leaves for better coverage.

You can see how it is a science and an art. Now, do you think generic companies do all of this? They do not. Also, when you choose to use a single generic active ingredient – such as generic azoxystrobin to prevent frogeye leaf spot and other diseases – you miss out on the benefits of additional modes of action available in premium premixes. Syngenta offers Quadris Top^® SBX fungicide, which contains the strobilurin ingredient, azoxystrobin, plus difenoconazole, part of the azole chemical class. These multiple modes of action have greater efficacy on diseases such as strobilurin-resistant frogeye leaf spot than generic azoxystrobin alone. Contact your local Syngenta representative for more information about Quadris Top SBX and how to get the best return on investment from your fungicide each season.

Scouting Tips for Black Cutworm in Sweet Corn

SyngentaAgronomy — Thu, 20 Jul 2017 20:14:43 +0000

Michigan State University Extension cautions of increased risk of black cutworm damage in sweet corn fields across Michigan this year. Michigan sweet corn growers should scout for black cutworm damage if black cutworm moth flights have occurred in their areas. Wet weather throughout the spring and recent storms created prime conditions for these pests to thrive. Following egg hatch, fields should be scouted weekly until sweet corn has more than 6 leaves. To scout, inspect 100 plants in 3 locations throughout the field. If damage is present, treat for black cutworms with a pyrethroid insecticide. Bt corn with the Vip3A trait also provides protection. To prevent black cutworm damage, Syngenta recommends Attribute® and Attribute® II trait stacks. The combination of Vip3A with Cry1Ab, the protein found in Attribute varieties, offer excellent control of key yield-robbing insects.

Timing Herbicide Application

SyngentaAgronomy — Fri, 21 Jul 2017 21:47:23 +0000

An effective weed control program depends heavily on well-timed herbicide applications, in addition to cultural practices. Failing to apply a herbicide at the right time could result in wasted input costs, weed infestations and reduced yield. Factors determining the timing of post-emergence herbicide applications:

Crop growth stage: Follow labels to avoid crop injury.
Weed growth stage: Scout fields regularly and treat weeds before they reach 4” in height.
Weather: Pay attention to weather, and refer to labels for required application conditions.

Overlapping residuals can help keep driver weeds, such as waterhemp and Palmer amaranth, down. As waterhemp grows, it develops multiple points of growth, which become increasingly hard to control with a herbicide. Scout fields regularly after herbicide applications to ensure that all points of growth on each weed are treated. The University of Illinois also reminds growers to use herbicides with multiple, effective modes of action on target weeds. Growers using a two-pass system in corn can follow their foundation rate of Acuron^® (groups 5, 15 & 27) or Acuron Flexi (groups 15, 27) corn herbicide with the remaining rate. Halex^®GT corn herbicide (groups 9, 15 & 27) can also be applied post-emergence and brings an additional mode of action to the table. Soybean growers can follow their pre-emergence herbicide applications with Prefix^® (groups 14, 15) residual herbicide and/or Flexstar^® GT 3.5 (groups 9, 14) herbicide for a robust two-pass herbicide program.

Japanese Beetles Wreaking Havoc on Midwest Soybeans

SyngentaAgronomy — Mon, 24 Jul 2017 16:19:31 +0000

After hearing late June reports of Japanese beetles beginning to show up in soybean fields of eastern Nebraska and Illinois, we’re now seeing their presence in significant numbers. Donald Lewis, Entomology Professor at Iowa State University, says 2017 will be remembered as one of the worst years in recent memory for Japanese beetles in Iowa. When scouting for Japanese beetles, University of Illinois says to look for:

Metallic, green bodies
Half inch long
Bronze-colored wing covers
Six small tufts of white hairs along the side of their bodies

Should Japanese beetles reach the local thresholds in soybean fields for your state, Syngenta recommends treating them with Endigo^® ZC insecticide, a proven solution to prevent soybean damage from a wide range of pests for higher yield potential.

Soybean Aphids Reaching Economic Thresholds

SyngentaAgronomy — Tue, 25 Jul 2017 22:05:36 +0000

In a recent Twitter poll, 48% of respondents voted soybean aphids as the most concerning soybean insect this season. In another Twitter poll, 55% of respondents said soybean aphids are the biggest yield robbers. These concerns are warranted: Purdue University estimates that damage from soybean aphids can cause 10-15% yield loss each season. The North Dakota State University Extension said soybean aphids have reached economic thresholds in Grand Forks and Walsh counties in North Dakota. Although soybean aphid populations are still below threshold in many other regions of the state, the university states the aphids are slowly increasing in numbers. Recently, the University of Minnesota Extension reported soybean aphids are being found in most fields throughout the state, and populations have reached economic threshold in some fields in northwest Minnesota. Many of these fields have required insecticide applications to protect soybean yields. When scouting for soybean aphids through the end of August, look for:

1/16“ in size
Yellow bodies
Black cornicles
Often found under soybean leaves

If soybean aphids reach thresholds in your region, we recommend using Endigo^® ZC insecticide, which contains two active ingredients and provides quick knockdown and extended residual control of key foliar pest populations, including soybean aphids. Using an insecticide treatment when soybean aphids reach the economic threshold is an essential part of maximizing yield potential.

Be On the Lookout for Bollworms in Soybeans

SyngentaAgronomy — Wed, 26 Jul 2017 23:04:23 +0000

This summer, concerns are high about bollworm (also known as corn earworm) infestations. Diligent scouting and monitoring is a must, as spotting pests early increases your chances of protecting soybean yields. Monitoring With large populations of bollworms infiltrating fields, recognizing threshold levels can help save your crop from further injury. These pests can be challenging to find, making it difficult to get an accurate sample. The drop cloth threshold may be 3 per foot of row, but this technique can sometimes be impossible to use between narrow rows of soybeans, forcing farmers to bend the plants over and visually examine them. This can cause confusion and tarnished information. According to Mississippi State University, using a recently developed economic threshold indicator has been proven effective at predicting accurate levels. By looking at price points and control costs, the pests-per-sweep method becomes easier to utilize. Once levels have been reached, it is time to take bollworms down. Syngenta recommends Besiege®, a broad-spectrum insecticide providing both rapid knockdown and long-lasting residual control of lepidopteran, sucking and chewing insect pests.

Tips to Identify Top Insect Pests in Mid-South Soybeans

SyngentaAgronomy — Thu, 27 Jul 2017 02:24:22 +0000

With summer reaching its peak, growers still need to be on alert for insect pressure, as entomologists are noticing heavier-than-expected populations in some areas. As we head toward harvest, this makes pest recognition especially important. Here are some tips for identifying insects of top concern this summer: Corn Earworm

Pale yellow-brown in color
Irregular wing markings
Wingspan of 1.5 inches

Bean Leaf Beetle

Red to yellow in color
Quarter-inch long
Four black spots on back

Stink Bugs

Redbanded stink bug: Green with red and yellow bands across the back.
Green stink bug: Bright green with black bands on their antennae.
Southern green stink bug: Green with rounded spine between hind legs.
Brown stink bugs: brown with yellow to light-green undersides.

Integrated pest management is a comprehensive approach for controlling insects. Remember to scout regularly, while observing field borders and monitoring moth flights. When pests reach threshold levels, we suggest Besiege®, a broad-spectrum insecticide that fights off destructive lepidopteran pests like corn earworm and bean leaf beetle across a broad range of crops. For stink bug control, regardless of species, we recommend Endigo® ZC insecticide, for quick knockdown and extended residual control of key foliar insect pests in soybeans.

Tips for Managing Late-Planted Soybeans to Maximize Profit

SyngentaAgronomy — Thu, 27 Jul 2017 16:47:14 +0000

With diseases becoming more apparent in soybean fields at this point of the season, it’s important to be thinking about the benefits of applying a fungicide before it’s too late. Late-planted soybeans are more vulnerable to diseases like frogeye leaf spot (FELS), as they have a higher chance of being infected at earlier growth stages. In a recent Syngenta Twitter poll, 67 percent of respondents agreed: With heavy spring rains delaying planting in several regions earlier this year, we recommend growers apply Quadris Top^® SBX fungicide, which contains difenoconazole for preventive and curative control of strobilurin-resistant and susceptible FELS. Quadris Top SBX also contains azoxystrobin, which delivers plant health benefits to promote root strength and pod fill. In field trials with high disease pressure, Quadris Top SBX plots yielded up to 23 bushels per acre (bu/A) over untreated soybeans.

Dry, Hot Climate Increases Whitefly Populations in Florida

SyngentaAgronomy — Fri, 28 Jul 2017 20:30:59 +0000

Warmer temperatures this past winter and spring, accompanied by the recent Florida droughts, created ideal conditions for whiteflies across the southeast. The hot, dry conditions this summer have left some vegetable growers with heavy pest pressure. In regions where whiteflies have been identified or are known to invade, Minecto® Pro broad-spectrum, foliar insecticide offers growers another tool to help manage this pest. With two complementary modes of action, Minecto Pro will control multiple pest populations that overlap or occur at the same time. When it comes to managing whiteflies in future crops, getting ahead of the population is key. Field hygiene is critical and should be integrated into an overall management program. Hygiene practices, such as crop destruction immediately following final harvest, will help manage existing populations. In addition, controlling weeds that attract whiteflies and act as potential hosts during the pre-plant period can help reduce infestation risk as well.

California Almond Trials Focus on Blossom Blight, Naval Orangeworm

SyngentaAgronomy — Fri, 28 Jul 2017 21:19:30 +0000

In our almond disease management trial at the Hickman, CA, Grow More Experience site, we are testing the efficacy of a wide range of fungicides against early- and late-season diseases. We are already seeing instances of shothole and brown rot blossom blight. There is a clear distinction between the trees that are untreated versus those that have been treated with a fungicide. Shothole Blossom blight is one of the most devastating diseases an almond tree might encounter because it can kill an entire stem. In order to get ahead of this disease, the first recommended fungicide application should be just before bloom in the pink bud stage. Vangard® fungicide will reduce the risk of blossom blight. Blossom blight As the season progresses, we expect that diseases such as alternaria, anthracnose, green fruit rot, rust and scab will begin to spread. Manage Insects to Protect Nuts Our almond insect management trial focuses on protection against navel orangeworm and mites. We are currently evaluating May sprays of Minecto® Pro insecticide. So far, it shows excellent early-season control of navel orangeworm and spider mites. As almond hull split begins, apply products like Besiege® insecticide (recently registered for use on almonds) to prevent navel orangeworm from laying eggs in the hull. Stay tuned for more information about the progression of and protection against diseases and insects in this trial throughout the season.

California Wine Grape Growers: Begin Mealybug Monitoring

SyngentaAgronomy — Fri, 28 Jul 2017 21:55:44 +0000

At the Hickman, CA, Grow More Experience site, we have begun to see increased activity from mealybugs, a common insect in wine grapes in this area of California. When mealybugs feed on wine grapes, they damage the grape and leave behind a sticky honeydew residue that causes mold to grow and attracts ants. In a few places at the Hickman site, ants were beginning to infest the area where mealybugs had damaged the grapes on the vine. It’s important to check your vines often for any signs of mealybugs. Look for groupings of the insects around vines and grapes. You’ll notice them clustering up in colonies. To help protect the grapes from mealybug damage, consider Platinum® 75SG insecticide to keep mealybugs from beginning to feed on the grapes.

Battling Late Blight in Potatoes

SyngentaAgronomy — Wed, 02 Aug 2017 23:00:56 +0000

Preventive planning is a key aspect of protecting potatoes from yield-robbing disease like late blight. This disease thrives under cool, wet weather, and the disease cycle may be interrupted during dry spells, but will progress when damp weather returns. In addition to leaves, stems and petioles, potato tubers are also susceptible to late blight.

The first symptoms of the disease are small, light to dark green, circular to irregular-shaped water-soaked spots. Lesions usually appear first on the lower leaves of potatoes. A white cottony mildew develops on and around foliar lesions.

With harvest approaching, it is important to look ahead to next year’s growing season. Extension experts remind growers about the importance of starting each season with clean potato seed as a first line of defense against some key potato diseases, including late blight.

Syngenta recommends Orondis® Opti, a fungicide that offers reliable control, even under heavy disease pressure. A foliar fungicide that combines two active ingredients, oxathiapiprolin and chlorothalonil, Orondis Opti defends against late blight on potatoes by protecting the crop when it is most actively growing and by helping to maximize marketable yields.

See What’s Bugging Iowa Soybean Growers

SyngentaAgronomy — Thu, 03 Aug 2017 20:41:49 +0000

One pest issue that is no stranger to Iowa soybean growers is the Japanese beetle. This insect defoliates soybean plants by chewing tissue between the leaf veins, creating webbed-looking leaves. Japanese beetles can reduce yield potential by clipping silks and damaging leaf tissue and pods on soybean plants. According to Syngenta agronomists at the Slater, IA, Grow More Experience site, Japanese beetles have been a common issue across much of Iowa this year. To protect against Japanese beetle, growers can follow 2 management steps:

Scout soybean fields often. Japanese beetles will primarily feed on the upper leaves, so check the top leaves for their presence or look for a web-like leaf appearance. While damage will primarily be on the upper leaves, evaluate the entire canopy for defoliation to determine the extent of the damage.
If beetle damage has removed 30% of the leaf area before pod set or 20% or more of the leaf area after pod set, growers can use a foliar insecticide to knock down further damage before yield loss occurs.

For Japanese beetle control, Syngenta recommends an insecticide like Endigo® ZC, which helps provide quick knockdown and extended residual control of key foliar insect pests in soybeans.

Expert Declares It’s Stink Bug Scouting Time

SyngentaAgronomy — Fri, 04 Aug 2017 21:40:01 +0000

Dr. Kelley Tilmon, pest specialist at the Ohio State University Extension, says now is the time to scout for stink bugs. With soybean plants reaching pod development, it’s an important time to monitor the stink bug pressure that lives within your fields. Tilmon’s research indicates many soybeans in 2016 had significant stink bug damage that went unnoticed until harvest - damage often stays undetected because pods usually hold their shape regardless of injury. Growers can prevent pod damage by scouting and treating fields at appropriate threshold levels. Tilmon recommends scouting for several species of stink bugs, including green, brown, red-shouldered and brown marmorated stink bugs. If stink bugs reach the recommended local threshold in your fields, we recommend using Endigo^® ZC insecticide to provide quick knockdown and extended residual control. Staying on top of scouting efforts and being prepared with an effective insecticide treatment are essential components of maximizing yield potential.

Common Rust Arrives in Pana, Illinois

SyngentaAgronomy — Mon, 07 Aug 2017 18:50:36 +0000

Caption: Pana, IL: Common rust spores on the surface of a corn leaf. Common rust arrived at the Pana, IL, Grow More Experience site mid-July, and there are concerns the more destructive southern rust may not be far behind. Southern rust has already been confirmed just to the south in Arkansas and thrives in the hot, dry conditions that have plagued southern Illinois for the past month. Of the two rust diseases, southern rust poses the greatest threat to yield potential. However, both common and southern rust can be treated with a properly-timed fungicide application. Scout early and often to identify either disease before they negatively impact yield potential. Syngenta offers Trivapro® fungicide for best-in-class preventive and curative control of rust and other difficult-to-control diseases. Trivapro also delivers plant health benefits such as stronger stalks, healthier roots and bigger ears for maximum return on investment.

Photo taken July 20, 2017. A June update from the Pana, IL, Grow More Experience site highlighted the importance of using multiple, effective herbicide modes of action to control waterhemp. Just over a month later, the same plot revealed the importance of residual control. Rows treated with Acuron corn herbicide (left) showed residual weed control through canopy, allowing corn to go into the grain-fill stage without having to compete for nutrients, water and sunlight. Meanwhile, rows that received only a pre-emerge application of atrazine (right) showed stunted growth because of early-season waterhemp pressure.

Two-spotted Spider Mites Persist in Soybeans

SyngentaAgronomy — Tue, 08 Aug 2017 21:44:47 +0000

Despite recent rainfall, two-spotted spider mite (TSM) pressure continues in soybeans. The Iowa University Extension recently received reports of high TSM numbers across several counties in southeast and south central Iowa. The University of Delaware Extension says TSM populations have also withstood the recent rain events in the state. When scouting for TSM, keep the following things in mind:

The pests gather underneath leaves.
Feeding leads to a speckled pattern on the upper leaf surface.
Severe damage leads to yellow or bronze areas in the field.
They typically move around field edges.

The University of Delaware Extension says preliminary results of Agri-Mek^® SC insecticide show excellent control of TSM. Once TSM levels reach the state-determined economic threshold, we recommend applying Agri-Mek SC for extended residual control. Agri-Mek SC can also be easily tank mixed with Endigo^® ZC insecticide for control of soybean aphids, Japanese beetles, and stinkbugs.

Last Chance to Protect Against Northern Corn Leaf Blight

SyngentaAgronomy — Wed, 09 Aug 2017 15:54:21 +0000

Growers in the Midwest recently reported on Twitter that they’ve seen northern corn leaf blight (NCLB) in their fields, with the University of Wisconsin-Extension recently confirming disease presence in the southern part of the state. NCLB can cause significant yield loss if it develops prior to or during silking. Identifiers:

Olive green or black fungal spores
Long, narrow lesions down the leaf
Oblong lesions on the leaf tissue

Damon L. Smith, extension field crops pathologist at the University of Wisconsin, says fungicides should be applied at the early onset of the disease and only if the epidemic is expected to get worse. While fields in some regions have reached or surpassed the recommended R1 fungicide application timing, it’s also important to survey today’s disease pressure to help plan for next season. For those who have corn approaching R1, you still have the opportunity to combat harmful and yield-limiting foliar diseases such as NCLB. For protection against this disease, Syngenta recommends growers apply Trivapro^® fungicide for harder-working, longer-lasting preventive and curative disease control to maximize yield and profit potential this season.

Preventative Disease Management in Squash

SyngentaAgronomy — Fri, 11 Aug 2017 21:23:15 +0000

When diseases like powdery mildew strike cucurbit crops, they can reduce yields and plant quality. First appearing as pale yellow spots, powdery mildew slowly covers the surface of the plant while producing spores that give the surface a powdery white coating. The University of California offers a few tips for managing the disease. Planting resistant varieties is a good way to help prevent powdery mildew infections. Resistance breeding is a priority for Syngenta, as evidenced with the introduction of new varieties like Grandprize squash and Spineless Supreme zucchini. Both varieties offer enhanced resistance packages to diseases like powdery mildew. Learn more about Syngenta squash varieties and disease resistances here.

Three Tips for Effective Weed Management in Iowa

SyngentaAgronomy — Fri, 11 Aug 2017 22:08:46 +0000

When you come up against prolific seed producers like waterhemp and Palmer amaranth, you can have problems not just this year, but for years to come. At the Traer, Iowa, Grow More^TM Experience site, we have been conducting a variety of corn and soybean trials to show you effective tools to manage these yield-robbing weed issues. Based on this year’s weed pressures, there are 3 main takeaways for consideration as you begin planning your 2018 weed management strategies in corn and soybeans:

Use full herbicide rates. Apply PRE and POST herbicides at full, labeled rates and at the correct growth stage for effective control. Lower than recommended application rates can lead to weed outbreaks and eventual resistance.
Strategically plan herbicide timing. Reports this year show growers struggling with their application timing. A common mistake is that they wait for “all” the weeds to emerge before they apply herbicides, which can be a costly decision. Herbicide application must happen before the weed is 4 inches tall or the possibility of control is slim-to-none. The earlier the timing, the better control you will see throughout the growing season. Although the chart below is from a study in Tennessee with Flexstar® herbicide, it’s a good visual for Iowans, too. The chart demonstrates management of Palmer amaranth at various growth stages, showing the importance of getting your herbicides down early.

3. Plan for a 2-pass system rather than a 1-pass system. An effective weed management program depends heavily on well-timed herbicide applications in addition to cultural practices. Failing to apply a herbicide at the right time could result in wasted input costs, weed infestations and reduced yield. Growers are reminded to implement a 2-pass system that uses herbicides with multiple,effective modes of action. We recommend Acuron® herbicide followed by Halex® GT herbicide in GT corn and Boundary® 6.5 EC herbicide followed by Prefix® plus glyphosate herbicide in GT soybeans. By planning ahead and following recommended weed management practices, Iowa corn and soybean growers should see a decrease in weed pressure and overall stronger yield results in 2018.

Corn Earworm: Voted Most Harmful Southern Soybean Insect

SyngentaAgronomy — Tue, 15 Aug 2017 19:21:43 +0000

In a recent Syngenta Twitter poll, 37% of respondents voted corn earworm as the most harmful soybean insect. In his Syngenta Pest Patrol Alert, Scott Stewart, entomologist with the University of Tennessee, cautioned growers along the Mississippi River to watch out for corn earworm, especially in later-planted beans as they get closer to flowering. Growers should scout now and use their sweep nets to assess corn earworm pressure, particularly in open-canopy soybeans where the insect usually gravitates to first. Corn earworms are usually a problem beginning at first bloom through R3. When scouting, growers should look for insects that are yellow, green, brown or black in color, with markings on their backs. He defines the treatment threshold as 7-9 worms on 25 sweeps. Once corn earworms reach the state-determined economic threshold, growers should consider applying Besiege^® insecticide for quick knockdown and extended residual control to help maximize yield and profit potential. Stewart says reports of Besiege insecticide corn earworm control have been good so far.

Southern Rust Confirmed Across Midwestern Corn Fields

SyngentaAgronomy — Wed, 16 Aug 2017 18:33:25 +0000

Map updated August 14, 2017 The recent update of the Integrated Pest Information Platform map shows Southern rust has spread northward throughout the Midwest. In northern Illinois specifically, Southern rust and common rust do not have the ability to overwinter, but can move north with wind currents. Common rust thrives in cooler temperatures while Southern rust develops in warmer weather. Although northern Illinois has been cooler this year, neighboring regions have been warmer and drier than normal, making corn in these regions more susceptible to rust this season. If neighboring regions have confirmed Southern rust, it’s best to treat fields proactively - it’s easier to prevent corn rust than to treat for the disease once damage is noticeable. If fields are nearing or close to R1 growth stage, there’s still time to apply a fungicide to shut down disease and protect yield. Syngenta offers Trivapro^® fungicide for harder-working, longer-lasting preventive and curative control of rust and other difficult-to-control diseases. Trivapro also delivers plant health benefits that help maximize grain fill and produce stronger stalks for reduced lodging and volunteer corn, resulting in maximum yield and return on investment.

Southern Corn Rust a Danger to Untreated Arkansas Corn

SyngentaAgronomy — Thu, 17 Aug 2017 15:51:38 +0000

Bay, AR. Trivapro treated corn (left) vs untreated corn (right). Southern corn rust present. Bay, AR, situated outside Jonesboro in Northeast Arkansas, experiences pressure from southern corn rust most years. This one is no exception. Under favorable weather conditions, yield loss from southern corn rust can be severe, reducing yields by as much as 25 bu/A on susceptible hybrids. This disease prefers damp and warm field conditions. Although the beginning of the season was cooler than usual in Arkansas, it was extremely wet. When it did heat up, that moisture aided in the development of the disease, which can seriously damage the crop. The best solution is to prevent infection by applying a foliar fungicide like Trivapro®. At our Grow More Experience site in Bay, AR, our agronomy team and visitors have been impressed by the Trivapro treated corn. The photo above demonstrates why. Corn treated with Trivapro is disease free and still green so that the leaves continue to feed the ears for maximum grain fill. The untreated corn is covered in disease and dying back, which means less grain fill. When dealing with diseases like southern corn rust and other late-season diseases, Syngenta encourages growers to time fungicide sprays at the VT/R1 stage before late-season diseases strike. The longer-lasting residual of Trivapro will keep rust and other difficult to control diseases under control.

Protect Your Wheat Fields from Toppling Over

SyngentaAgronomy — Fri, 18 Aug 2017 19:40:27 +0000

Regardless of geography, one of the biggest threats to yield that all wheat growers can face is wheat lodging. Wheat lodging can be caused by excessive early nitrogen, application overlaps and residual nitrogen build-up from manure. According to the University of Kentucky extension, the higher a grower’s individual yield goal, the more important nitrogen management becomes. The timing of nitrogen is as important as the amount of nitrogen applied. Excessive early nitrogen can cause wheat to grow too quickly, increasing stem height and reducing stem thickness. When combined with heavy wind or rain, standability becomes difficult for weak stalks. In extreme situations, this can cause yield losses of up to 40% – a disaster for growers. Applying a plant growth regulator like Palisade^® EC can mean the difference between strong yield results and devastating losses. A plant growth regulator can help ease lodging challenges caused by weather or higher nitrogen levels. By strengthening the stem and shortening plants, lodging is reduced and standability is improved, as demonstrated in the chart below. Consider adding a plant growth regulator like Palisade EC to your wheat management plan to help improve stalk strength and protect your yields from toppling over.

Spider Mites Infesting Michigan Soybeans

SyngentaAgronomy — Mon, 21 Aug 2017 21:11:55 +0000

The University of Michigan Extension reports spider mites are beginning to infest soybean fields in different areas of the state. Last week was the first report of spider mites in Kalamazoo-area fields. Though much of Michigan has been wet this summer, there have been areas throughout southwest and south central Michigan that have been hot and dry, which are conditions conducive to a spider mite presence. Spider mite scouting tips:

Pull up some of the affected plants, shake them over a white piece of paper and wait for about 30 seconds.
If spider mites are present, you will see what looks like small grains of sand start to move on the paper.

The Michigan State University Extension defines the following thresholds (based on percent yellowing) for spider mite treatment:

Pre-bloom = 40%
Bloom R1 to pod fill R5 = 15%
R5 to early maturity R7 = 25%
After R7 = do not spray, as damage at this point has little impact on yield

If weather remains hot and dry, spider mite populations are more likely to thrive. Once spider mite levels reach the economic threshold, we recommend applying Agri-Mek^® SC insecticide for extended residual control. Additionally, Agri-Mek SC can be easily tank mixed with Endigo^® ZC insecticide for control of soybean aphids, Japanese beetles and stinkbugs.

Pest Watch for 2017 Winter Wheat Planting

SyngentaAgronomy — Mon, 21 Aug 2017 22:09:35 +0000

According to The National Weather Service, meteorologists are predicting above-average temperatures for the southern and eastern United States and above-average precipitation in parts of the south from September to November this year – just in time for winter wheat planting. Warm and wet weather combined with newly-planted wheat seed can create ideal disease and insect conditions. These pests can attack wheat seedlings early, long before growers know what’s lurking below the soil. Damage from pests can lead to late emergence, poor establishment and weak seedling vigor. For the 2017-2018 winter wheat season, growers should look out for the following pests:

Pythium - One of the most prevalent disease pathogens attacking cereal crops, Pythium can cause delayed emergence, damping off, stunted growth, and thin plant stands. Research from Washington State University indicates that wheat seeds left unprotected are likely to become infected by Pythium within the first 24 to 48 hours after planting in moist soils.
Fusarium - Fusarium attacks the outside of the seed and the seed embryo. If infected with Fusarium, the seed may die, germinate poorly or encounter seedling blight as it germinates.
Rhizoctonia - Rhizoctonia lives as a fungus in soil, infecting seeds and young seedlings after water absorption. Capable of causing 20 to 40% yield loss, Rhizoctonia can cause germination failure, stunted crops, and reduced nutrient absorption and vigor.
Aphids - Some species of aphids, including greenbugs, transmit barley yellow dwarf virus (BYDV), which can cause underdeveloped root structure, delayed maturity, nutritional disorder and reduced grain quality and yield. Fall infections of BYDV are worse than the spring infections, but it can be difficult to tell when infection occurred because growers may not see symptoms of the disease until spring.

Planning early with a seed treatment like CruiserMaxx® Vibrance® Cereals insecticide/fungicide or Vibrance® Extreme fungicide can help young seedlings thrive through the most challenging conditions. Our seed treatment line-up can provide seed protection that stimulates quality root systems to deliver better emergence, stand establishment, nutrient uptake and stress tolerance to help plants overwinter better.

From stripe rust in North Carolina and Virginia to powdery mildew in Kentucky and Oklahoma to tan spot in Oklahoma, winter wheat fields faced many challenges because of earlier warm and wet weather patterns. The key to a successful 2017-2018 winter wheat season is to get ahead with a proactive disease management plan. Follow these 3 tips to help knock out diseases:

Know your opponent. Since disease pressure in wheat is closely tied to weather, it can be unpredictable. Some diseases, like stem rust, favor warm temperatures and strike later in the season. Others, like stripe rust, prefer cooler temperatures and start in southern states before spreading north. Being able to use environmental “tells” can help growers predict when diseases may hit their fields.
Scout regularly. To stay ahead, growers should scout early and at multiple stages of the growing season, increasing intensity during potential outbreaks.
Plan for a fungicide spray. It only takes a small amount of inoculum for a disease to develop and spread under favorable weather conditions. To prevent its spread, be proactive and apply a fungicide like Trivapro^® for longer-lasting control of key foliar diseases. When diseases are controlled, like in the photo above, leaves remain green to help fill out wheat heads and deliver higher yields.

Control Corn Rootworm with Added Convenience

SyngentaAgronomy — Wed, 23 Aug 2017 19:19:00 +0000

Corn rootworm (CRW) is a tiny pest that can take a big bite out of a farm’s bottom line. Each year, it is estimated to cost U.S. corn growers more than $1 billion, so it’s important to have highly effective insecticides to control the pest before it damages corn. Using a robust soil-applied insecticide is an effective way to manage the risk of CRW damage year after year. Growers looking for that superior control of CRW and other early-season pests will have access to Force® Evo liquid corn insecticide starting in the 2018 growing season. This enhanced formulation contains the same trusted active ingredient, tefluthrin, as other Force brand insecticides to deliver performance and convenience. Among the three farmers from across the Midwest who were able to trial Force Evo this season was Michael Guerts of Marshall, MN. Guerts is excited to use Force Evo in his fields during the 2018 season thanks to the ease of mixing with liquid starter fertilizer. He’s trusted Force for years thanks to its insect protection, but believes that Force Evo will give him the convenience he needs. The formulation benefits – including better cold tolerance, less viscosity, greater starter fertilizer compatibility and easier equipment cleanout – will result in increased at-plant efficiency. And thanks to its easy-to-load packaging, growers can expect to speed the planting process with fewer delays. We made the Force Evo formulation less viscous so you will have hassle-free planting without delays. This photo shows the superior flowability of Force Evo (left) compared to the thicker Force® CS formulation (right).

Six Ways to Boost Your Crop's RootingPower

SyngentaAgronomy — Fri, 25 Aug 2017 21:32:27 +0000

Growers should keep root health at the top of their mind when preparing for next season. Lush and robust wheat fields start with durable, deep and disease-free roots. These roots are better able to absorb important nutrients and moisture that produce healthy plants and increase yield potential. As a part of an ongoing commitment to root health and pest defense, Syngenta Seedcare scientists analyzed the interactions between roots, disease, moisture efficiency and nutrient utilization and found that sedaxane, the active ingredient in Vibrance®, boosts each plants RootingPower™ from the start. By incorporating preventive measures now – including best management practices and seed treatment applications – growers can get their crops started on the right foot. Below are the 6 benefits of Vibrance RootingPower:

Vibrance protects seeds and emerging seedlings from Rhizoctonia by creating a “halo of protection” around the seed and root system.
RootingPower is the link between strong roots and increased yield. The built-in RootingPower of Vibrance leads to more powerful, healthier roots.
Robust root systems efficiently absorb and utilize moisture and nutrients, improving crop performance.
Enables plants to withstand environmental stresses.
Allows faster germination and emergence, improving stand establishment.
Greater stands leads to maximum yield potential year after year.

Order of Burndown and Vertical Tillage Critical for Weed Control

SyngentaAgronomy — Mon, 28 Aug 2017 20:22:48 +0000

Caption: Pana, IL: Agronomy Service Representative Nate Prater talks to growers about the importance of applying a burndown herbicide application before using vertical tillage in soybean fields. A demonstration plot at an Aug. 16 Grow More Experience event in Pana, IL, highlighted the importance of burndown timing when using vertical tillage. A burndown application of 3pt/A Gramoxone® SL 2.0 herbicide was applied on two plots, and the only difference was application timing. One plot was treated with Gramoxone SL 2.0 before vertical tillage and the other was treated with Gramoxone SL 2.0 after vertical tillage. Both plots also received an application of 2 pt/A Boundary® 6.5 EC herbicide to simulate a pre-emergence application of a residual herbicide. The results showed a clear difference in weed control: Caption: Bare ground treated with Gramoxone SL 2.0 before vertical tillage (Bottom) vs. bare ground treated with Gramoxone SL 2.0 after using vertical tillage (Top) shows a clear difference in weed pressure. Start clean and stay clean in 2018 with a burndown application before vertical tillage. This gives you the chance to incorporate another mode of action into your weed management program. Then before planting, make a pre-emergence application of a residual herbicide with additional modes of action to provide extended weed control until post-emergence timing.

Alert: Pests Spotted in Arkansas

SyngentaAgronomy — Mon, 28 Aug 2017 22:13:30 +0000

Arkansas – According to entomologist Dr. Gus Lorenz, in rice and soybeans there have been sightings of:

Red banded stink bugs
Soybean loopers

Red banded stink bugs continue to be an issue. Some behavioral differences have been noticed between red banded and other varieties of stink bugs. On cool mornings, red banded stink bugs will travel to the base of the plant and onto the soil to capture radiant heat coming off the ground. Because of this movement, growers scouting for pests early in the morning might miss these insects, so make sure to wait until later in the day. To hear more about pests and management solutions, listen to Dr. Lorenz’s Pest Patrol update. For fields that have reached threshold levels, consider Syngenta insecticides like Besiege®.

Soybeans treated with CruiserMaxx Vibrance Beans seed treatment. With harvest coming up across the country, it’s hard not to look forward to seeing how well your full soybean management programs performed. While you look back at your herbicide programs, soybean variety choices and this season’s weather, one important aspect may be overlooked: seed treatments. While most use a soybean seed treatment of some kind, all too often the importance of selecting the right seed treatment is overlooked. Although the color of different seed treatments may be the same, the performance isn’t. And with lower commodity prices, you may be looking at discount seed treatments as a potential opportunity to cut costs. We will be doing a series on the importance of the right soybean seed treatment, and the differences between seed treatment choices available today. Over the coming weeks we will cover the following topics:

Generic seed treatments – the increasingly common generic soybean seed treatments and the risks that surround them.
Branded seed treatments – branded seed treatment options on the market such as Acceleron^® Standard and Valent Intego^® Suite.
CruiserMaxx^® Vibrance^® Beans seed treatment – the market-leading insecticide/fungicide seed treatment from Syngenta and what it provides.
An overall look at the options growers have and what they need to consider as they make seed treatment decisions for the 2018 season.

This series will highlight the importance of investing in your seed treatment and focusing more on ROI than upfront costs. It will educate on the importance of your soybean seed treatment choice and how to best prepare for next year. What’s on your seed? Ask your retailer or seed treater today.

Use Harvest to Evaluate Corn Rootworm and Plan Defense

SyngentaAgronomy — Fri, 01 Sep 2017 22:14:05 +0000

Although corn rootworm (CRW) pressure has been low in many areas this season, there’s no guarantee how long that will last, nor that it holds true for all cropping situations. Corn-on-corn and certain soil textures tend to be more conducive to CRW. Historically, CRW is the most destructive corn pest in the United States, costing growers more than $1 billion annually in reduced grain yield and control measures. Damage from CRW includes underdeveloped root systems, weak brace roots, reduced nutrient uptake, poor ear fill, and lodged or fallen corn. Beetles feed on new silks and stunt pollination. Feeding sites serve as points of entry for disease and further crop damage. Ultimately this results in fields that are tough to harvest, with low yields and reduced profits. And if left uncontrolled, they lay eggs to introduce the cycle again the following season. Test plot in Princeton, IL: Non-trait hybrid (left) vs. competitive hybrid (middle) vs. Agrisure Duracade 5222 E-Z Refuge (right). As you evaluate your corn crop performance this season, pay attention to symptoms and presence of CRW. Then as you plan for 2018, assess your fields’ risk factors to help choose appropriate hybrids. Agrisure Duracade trait stacks provide season-long CRW control, helping protect against CRW damage throughout the pest’s lifecycle by limiting beetle emergence. For fields battling both CRW and other above-ground pests, the Agrisure Duracade 5222 E-Z Refuge® trait stack delivers that ultimate level of protection. This trait stack combines the CRW control of the Agrisure Duracade trait with the above-ground insect control from the Agrisure Viptera® trait. Visit the Agrisure Duracade webpage to learn more.

Alert: Pests Spotted in Mississippi

SyngentaAgronomy — Wed, 06 Sep 2017 18:43:53 +0000

Mississippi – According to entomologist Dr. Angus Catchot, in soybeans there have been sightings of:

Soybean loopers

Despite a high percentage of insects, Catchot believes fields may remain safe. Cool weather can help foster viruses, and with low temperatures predicted over the next few days, the possibility of looper virus increases. These diseases have the capability of spreading through fields quickly, destroying large populations of loopers. To hear more about pests and management solutions, listen to Dr. Catchot’s Pest Patrol update. For fields that have reached threshold levels, consider Syngenta insecticides like Besiege®.

Considerations for Generic Soybean Seed Treatments

SyngentaAgronomy — Thu, 07 Sep 2017 17:18:15 +0000

Dust-off from a generic seed treatment This is the second post in our ongoing soybean seed treatment series: What’s on Your Seed? Low commodity prices for soybeans may have you scaling back and making tough decisions about your inputs. By no coincidence, generic seed treatments, which are cheaper than branded options, are becoming more common. So what can you expect to get out of these unbranded, custom blends? Although these generic treatments are generally red in color and look similar to CruiserMaxx^® Vibrance^® Beans seed treatment, they are not the same. The lower cost of these generic seed treatments comes with increased risks. Here are some considerations that you need to prepare for if you choose generic seed treatments:

Dust off: Generic seed treatments often do not stick to the seed as well. This dust off means less of the treatment makes it on the seed, leading to a loss of effectiveness. Additionally, dust off can experience off-target movement according to the Penn State Extension.
Equipment clogging: Generic treatments are not tested as thoroughly and have a higher likelihood of not only clogging up the treater’s equipment, but on-farm equipment as well.
Incompatible mixtures and product separation: The active ingredients in generic treatments are not optimized for proper mixing and are more likely to separate like oil and water, as seen in the video below. This leads to seeds receiving inconsistent proportions of the ingredients. This means some seeds don’t receive enough of certain active ingredients, leaving them vulnerable to insects and diseases.

As you consider inputs for next year, remember that your seed treatment is an investment. Although generic seed treatments are cheaper, the performance is not a sure thing. When you are making your seed treatment decision, you cannot predict what the conditions will be when you plant – buying a generic seed treatment is a gamble. What’s on your seed?

Leaf Disease Strikes Again in Eastern Iowa

SyngentaAgronomy — Fri, 15 Sep 2017 21:11:01 +0000

Gray leaf spot can cause blocky lesions along the leaf. Throughout eastern IA, we’ve been seeing the effects of corn leaf diseases such as gray leaf spot and northern corn leaf blight (NCLB). At our Traer, IA, Grow More™ Experience site, Syngenta Agronomist Dean Grossnickle explained how to identify these diseases in your field. Gray leaf spot usually has blocky, gray/tan lesions along the plant’s leaf with symptoms starting to show up before tasseling. NCLB is known for long, elliptical cigar-shaped lesions, particularly if conditions are moist. It’s still important to pay attention to disease pressure in your fields this year so you can address those needs when making 2018 management plans, which can include:

Rotating your crops: Rotating corn fields with a non-host crop will help future corn crops be less susceptible since these diseases both overwinter.
Managing corn residue: Baling corn stalks or plowing down infected corn residue into the ground in the fall can help to prevent this from impacting yield potential in 2018. According to Grossnickle, future crops can become infected by corn debris left in the soil, if conditions allow for it.
Selecting hybrids for genetic protection: Think about selecting NK® Corn hybrids that are rated high for NCLB and gray leaf spot tolerance to give your field genetic protection against the disease.

Resisting the Yield-Robbing Effects of White Mold

SyngentaAgronomy — Tue, 19 Sep 2017 20:04:57 +0000

August and September are when you may see certain diseases manifest in your fields. Diseases like sudden death syndrome, brown stem rot and white mold can infect crops earlier in the season but don’t start to show visual symptoms until later in the summer, explains Dean Grossnickle, a Syngenta agronomist for the Slater, IA, Grow More™ Experience site. With this in mind, now is when you should be on the lookout for Sclerotinia stem rot (white mold) in soybeans. Following a cool, wet spring in 2017, conditions in the Upper Midwest and northern IA fields were right for the germination of sclerotia, allowing for susceptible plants to be infected by the disease. White mold can significantly decrease yield and spread to more fields if not managed properly. Visual white mold symptoms in soybean fields include a fluffy, white growth and black sclerotia along the stem or bean pods. To get ahead of the disease, consider the following steps:

Evaluate your fields for damage: According to Grossnickle, white mold typically causes the tops of soybean plants to start to turn yellow or brown. This is often one of the first visual indicators that the disease is in the field.
Fungicide use: If you’re using a fungicide, it needs to be timed perfectly to get the desired results, requiring intense scouting and monitoring of the weather. Cultural controls are usually more effective.
Select varieties that are rated high for white mold resistance: Many NK® Soybean varieties have built-in tolerance to white mold. NK Soybeans S20-J5X brand, S20-T6 brand and S22-J4X brand, which have excellent yield potential and outstanding tolerance to the disease, have had proven performance in areas affected by white mold throughout the Upper Midwest and northern IA. Talk to your local NK retailer if you’d like to add these varieties to your lineup.
Rotate to a non-host crop: Consider rotating to a non-host crop like corn for a period of time following recent infection in a field. This will help to mitigate the risk of white mold when returning to soybeans down the road

Get Ahead of Pest Problems in Winter Wheat

SyngentaAgronomy — Thu, 21 Sep 2017 16:20:48 +0000

Meteorologists are predicting above-average temperatures and variable precipitation for the Pacific Northwest from September to November this year – just in time for winter wheat planting. Warm and wet weather combined with newly-planted wheat seed can create ideal disease and insect conditions. These pests can attack wheat seedlings early, long before growers know what’s lurking below the soil. Damage from pests can lead to late emergence, poor establishment and weak seedling vigor. For the 2017-2018 winter wheat season, growers should look out for the following pests:

Rhizoctonia - Rhizoctonia lives as a fungus in soil, infecting seeds and young seedlings after water absorption. Capable of causing 20 to 40% yield loss, Rhizoctonia can cause germination failure, stunted crops, and reduced nutrient absorption and vigor.
Pythium - One of the most prevalent disease pathogens attacking cereal crops, Pythium can cause delayed emergence, damping off, stunted growth, and thin plant stands. Research from Washington State University indicates that wheat seeds left unprotected are likely to become infected by Pythium within the first 24 to 48 hours after planting in moist soils.
Fusarium - Fusarium attacks the outside of the seed and the seed embryo. If infected with Fusarium, the seed may die, germinate poorly or encounter seedling blight as it germinates.
Wireworms – These insects can damage wheat crops, increase weed pressure and reduce stands and yields. Wireworms feed on germinating seeds and young seedlings, but crop damage isn’t detected until after planting. Scouting for these pests prior to planting is crucial.

Planning early with a seed treatment like CruiserMaxx® Vibrance® Cereals insecticide/fungicide can help young seedlings thrive through the most challenging conditions. Our seed treatment line-up can provide seed protection that stimulates quality root systems to deliver better emergence, stand establishment, nutrient uptake and stress tolerance to help plants overwinter better.

Plan Ahead to Tackle Soybean Challenges

SyngentaAgronomy — Thu, 21 Sep 2017 17:09:43 +0000

With forces like weather, temperature, insects and disease as constant threats, protecting soybean crops at an early stage is crucial. Knowing the challenges you’ll face during the growing season is a must, as it helps provide the necessary tools to eliminate these issues. Some common problems can include:

Nutrient and fertility loss.
Fungal diseases like Rhizoctonia, Phytophthora, and Fusarium.

To provide your soybean crop with broad-spectrum control, we recommend CruiserMaxx® Vibrance® Beans insecticide/fungicide seed treatment. This treatment contains three fungicides for the broadest spectrum of control and maximum performance, and offers best-in-class insect protection and systemic root protection.

Protect Your Pulse Crops from Fast-Spreading Disease

SyngentaAgronomy — Thu, 21 Sep 2017 17:42:02 +0000

With the 2017 season drawing to a close, there’s no time like the present to start looking ahead to 2018. No season is perfect, so starting to consider adjustments for next year’s crops will help you realize new ways to plan for disease protection. Crop protection starts with identifying potential issues. One major disease of concern is seedborne ascochyta. In pulse crops, the disease can have a highly damaging effect on yield. When ascochyta attacks the seed, it leaves no symptoms. It is not until late vegetative stages or bloom initiation that symptoms appear. These include:

Tan and brown lesions.
Infection on leaves, stems and pods.
Discolored, shriveled seeds.

With a tendency to reach epidemic levels quickly combined with diseased pods often failing to produce seed, finding ascochyta in your field could be disastrous. To head off this disease before it takes hold, we recommend Vibrance® Maxx fungicide seed treatment. It offers protection against soilborne, seedborne and seedling diseases on crops like dry peas and beans, chickpeas and lentils.

Manage Fall Weeds in CA Orchards

SyngentaAgronomy — Thu, 21 Sep 2017 17:57:59 +0000

Aggressive weeds are becoming more and more difficult to control in California tree fruit and nut crops. With waning effectiveness of some post-emergence herbicides, dealing with these threats becomes increasingly important and challenging. As Broadworks® herbicide is the only group 27 herbicide in trees, it is a good rotation choice for resistance management. Two weeds that are particularly difficult to control are hairy fleabane and marestail. Both can grow in similar situations and look alike, especially as seedlings. These weeds directly compete with young trees for soil nutrients, water and sunlight. They interfere with harvesting, host insects, and reduce tree height and vigor. All these factors can lead to yield loss. When facing these weeds, we recommend Broadworks in a tank mix with another efficacious residual herbicide. As discussed in our previous post, this pre- and post-emergence herbicide controls glyphosate-resistant weeds like marestail and hairy fleabane, while also providing broad spectrum control of broadleaf species.

Protect Tree Roots from Phytophthora

SyngentaAgronomy — Mon, 25 Sep 2017 18:00:22 +0000

As the growing season moves into harvest, now is a good time to consider the next steps in orchard management, including protecting roots from soil diseases. If left unchecked, these diseases can overwinter and cause tree death. A major infection that can occur is Phytophthora. This water mold can cause root rot and occurs when the soil is oversaturated or left with standing water. When it comes to preventing infection, water management is key. Once infected, trees can begin to see poor vegetative growth, low fruit set, and orchard decline. The best way to check for this disease is by digging up roots and checking tissue and soil samples. Syngenta offers the Soil Pathogen Assessment (SPA), a free program that assesses Phytophthora infections on an orchard-by-orchard basis. Contact your Syngenta representative to learn more about soil sampling through the SPA program: www.Syngenta-US.com/rep-finder. In addition to field testing, consider using Ridomil Gold® SL fungicide, which offers long-lasting protection against soilborne diseases, including crown rot, collar rot and root rot caused by several Phytophthora species.

Protect Vegetable Crops from Chewing Pests

SyngentaAgronomy — Mon, 25 Sep 2017 19:10:35 +0000

With a wide variety of insects in Arizona and California, vegetable crops are constantly susceptible to attack. With yield and crop-quality in danger, make a pest management plan to protect fields. When addressing pests, it’s important to recognize what you’re up against. Some common insects found in vegetables include:

Blister beetles
Corn earworm
Grasshoppers
Tomato hornworms
Thrips

Combatting these lepidopteran and chewing insects can be difficult. When faced with these bugs, we recommend Besiege® insecticide. With two modes of action, Beisege is a broad-spectrum foliar insecticide that provides fast knockdown and long-lasting residual control of a wide range of pests.

Manage Spring Wheat Pests

SyngentaAgronomy — Tue, 26 Sep 2017 18:10:18 +0000

Starting your season with a strong crop management plan is the best way to protect your investment. It’s important to know and understand the disease and insect issues you’ll face in your fields. These pests can attack wheat seedlings early, long before you know what’s lurking below the soil. Damage from pests can lead to late emergence, poor establishment and weak seedling vigor. For the 2018 spring wheat season, growers should look out for the following pests:

Pythium - One of the most prevalent disease pathogens attacking cereal crops, Pythium can cause delayed emergence, damping off, stunted growth, and thin plant stands. Research from Washington State University indicates that wheat seeds left unprotected are likely to become infected by Pythium within the first 24 to 48 hours after planting in moist soils.
Fusarium - Fusarium attacks the outside of the seed and the seed embryo. If infected with Fusarium, the seed may die, germinate poorly or encounter seedling blight as it germinates.
Rhizoctonia - Rhizoctonia lives as a fungus in soil, infecting seeds and young seedlings after water absorption. Capable of causing 20 to 40% yield loss, Rhizoctonia can cause germination failure, stunted crops, and reduced nutrient absorption and vigor.
Aphids - Some species of aphids, including greenbugs, transmit barley yellow dwarf virus (BYDV), which can cause underdeveloped root structure, delayed maturity, nutritional disorders, and reduced grain quality and yield. Fall infections of BYDV are worse than the spring infections, but it can be difficult to tell when infection occurred because growers may not see symptoms of the disease until spring.

Planning early with a seed treatment like CruiserMaxx® Vibrance® Cereals insecticide/fungicide can help young seedlings thrive through the most challenging conditions.

This is the fifth post in our ongoing soybean seed treatment series: What’s on Your Seed? No matter your soybean yields this year, you’ll want next year’s yields to be even better. Start your 2018 season strong by purchasing the right seed treatment. As the first line of defense against early-season pests and diseases, such as Rhizoctonia, seed treatments are worth extra attention. While they may look the same on the surface, remember that not all seed treatments are created equal. Here are some key differentiators to keep in mind:

Generic seed treatments – often offered at a cheaper price but a gamble when it comes to application and performance.
Most branded and custom blend seed treatments – do not include the unique RootingPower of Vibrance^® fungicide or the Cruiser^® Vigor Effect of CruiserMaxx^® Vibrance^® Beans seed treatment, a combination of separately registered products, which keeps roots vigorous and healthy even in the absence of insect and disease pressures.
CruiserMaxx Vibrance Beans – delivers minimal application challenges, a market-leading field performance and an industry-leading ROI.

Keep Your Corn Ears From Tipping Back

SyngentaAgronomy — Thu, 28 Sep 2017 22:34:19 +0000

Missing kernels at the end of corn ears are often referred to as “tip back.” Tip back can often be associated with poor pollination, but it can also be a symptom of many different things occurring at different points in time. Though it is hard to determine exactly what causes tip back, agronomists usually associate it with stress. According to the University of Illinois, drought, loss of leaf area or lack of nitrogen can result in stress that lowers photosynthesis and in turn, decreases the sugar supply. This decrease in available sugars due to one or more infield stresses often results in kernels being aborted. While drought and/or reduced available nitrogen from a wet spring can’t always be avoided, artificial stress from planting too high of a seeding rate can be managed with good knowledge of how hybrids respond to high and low populations. It’s also important to understand that some hybrids naturally tip back more than others, so don’t always jump to the conclusion that you have a problem that may need to be fixed. Obviously there is nothing you can do to restore your missing kernels this year, but don’t beat yourself up. Even successful fields can experience varying amounts of tip back. Be sure to ask your Syngenta representative or NK^® Retailer for recommendations on how to choose the best population for your hybrid as well as minimize other stress on your hybrids in order to increase your kernel count.

The Newest Force in the Fight Against SCN

SyngentaAgronomy — Fri, 29 Sep 2017 20:48:17 +0000

Soybean cyst nematode (SCN), the silent yield robber, continues to take big bites out of yield every year. While SCN-resistant varieties have been a common tool in managing SCN in the past, the varieties utilizing the PI88788 gene are no longer as effective as they used to be. Iowa State University experts recommend that you enhance the performance of your SCN-resistant varieties with a nematode protectant seed treatment. However, not all nematicides are fit for the role. Because SCN reproduces exponentially throughout the season, you need a seed treatment that deals lethal blows to SCN all season long. Syngenta now offers Clariva^® Elite Beans seed treatment, the only seed-applied nematicide on the market that provides season-long activity against SCN. Clariva Elite Beans is an engineered premix formulation of the proven Clariva® pn seed treatment nematicide and CruiserMaxx^® Vibrance^® Beans seed treatment. Advantages of Clariva Elite Beans

Offers the only season-long lethal SCN activity
- Competitor seed treatments offer just early-season activity against SCN
Contains the unique RootingPower of Vibrance fungicide and the Cruiser^® Vigor Effect for optimized root health and plant vigor
Delivers an attractive return on investment (ROI) with an average yield increase of 2.7 bu/A, according to Syngenta trials
- In some fields, yield increases of more than 10 bu/A have been achieved

If left untreated, a single nematode can produce over 1 billion eggs in a season, infesting your fields for years to come. Think about your seed treatment as an investment in the future yield potential of your field. The convenience of Clariva Elite Beans combined with its unique season-long activity against SCN can help put you at ease from planting to harvest.

Prepare Management Plan for Rhizoctonia in Potatoes

SyngentaAgronomy — Fri, 06 Oct 2017 19:35:50 +0000

As we head into fall harvest, you may be thinking about next year’s planting. With the unpredictability of spring weather, growers should be prepared for diseases that sprout up during periods of low temperature. At the top of this list is Rhizoctonia, a pathogen that prefers cool, moist conditions and leads to poor stands and stunted plants. Rhizoctonia overwinters on infected tubers, in plant residue and infested soils. Black scurf is the most noticeable sign of infection, and causes black patches along the tuber. Stem cankers, however, are the most damaging, attacking and killing germinating sprouts. Understanding correct management techniques is crucial for protection. Following these essential tips will help alleviate disease pressure:

Avoid over-irrigating: Cool, damp soil can cause slow plant emergence and encourage fungal development.
Plant strategically: Encourage more rapid emergence through shallow planting.
Harvest timely: Potatoes should be harvested as soon as skin is set. The percent of infected tubers increases as the interval between vine kill and harvest increases.

For additional preventative support, we recommend CruiserMaxx® Vibrance® Potato insecticide/fungicide seed treatment. CruiserMaxx Vibrance Potato combines the power of three industry-leading fungicides to deliver comprehensive control of Helminthosporium, Fusarium and Rhizoctonia, while providing protection against key insects.

Control Perennial Weeds This Fall

SyngentaAgronomy — Fri, 06 Oct 2017 22:06:02 +0000

Many vegetable fields have problems with perennial weeds. The Michigan State University Extension encourages checking and treating for these weeds in the fall, so now is the time to control them before next growing season. Some of the most common perennial weeds are yellow nutsedge, quackgrass, pokeweed, milkweed and field bindweed. These weeds have perennial roots and annual tops, so they can go undetected before they emergence. Shorter days and cooler nights in the fall cause “shoot-to-root” movement in weeds as the plants carry carbohydrates into the roots. This movement can also carry systemic herbicides into the roots, providing protection that carries through to the next season. Checking and treating perennial weeds now can help ensure that herbicides are effective in the coming season. Applying a systemic herbicide is a good way to treat for perennial weeds to prevent problems from occurring next year. With proactive planning and season-long management, perennial weeds can be controlled with lower cost and fewer headaches.

Corn Rootworm Beetle On The Rise in Illinois

SyngentaAgronomy — Mon, 09 Oct 2017 15:11:19 +0000

After several years of low corn rootworm pressure (CRW), adult populations of this insect were reported to be on the rise in Illinois. Data collected in August by the University of Illinois reports a large number of adult Western CRW beetles in corn fields. Higher populations were observed primarily in the northeast and West, with results showing much higher adult beetle counts than the 6 year average. The 2 species to look out for are Western and Northern CRW beetles. Looking ahead, some things to keep in mind about these insects include:

Eggs are laid in mid-to-late summer and overwinter.
Eggs hatch from mid-May to early June
Larvae start feeding within 3-4 hours of hatching

Larvae Western Southern With a high number of beetles spotted in August, what does this mean for the 2018 season? While factors like temperature and weather over the next few months can affect the larval survival rate, it is still important to recognize the rising population and prepare accordingly. We suggest an insecticide like Force® Evo or Force® 3G that helps protect developing corn root systems against insects. For more information, please contact your local Syngenta Sales Representative.

It’s The Season for SCN Soil Sampling

SyngentaAgronomy — Thu, 12 Oct 2017 20:41:16 +0000

Soybean cyst nematode (SCN) is the top soybean pest in the U.S., contributing to yield losses as high as 30%. An effective SCN management program starts with a reliable way to detect SCN: soil sampling. Here are some tips on how to get the best results from your soil sampling efforts.

Avoid sampling in wet, muddy soils
Plan to sample in a zig-zag pattern
Collect many soil cores to cover spatially-scattered SCN populations
Probe or dig roughly 8 inches deep
Store your collected samples in a cooler and fridge
Ship them overnight to a lab during the week

Soil sampling should be done in the fall every 2-3 soybean seasons so that you can monitor SCN levels over time. After harvest, but before the first frost, is the most effective time to sample for SCN because the population density will be at its peak. Researchers with the Iowa State University Extension encourage fall soil sampling because it can explain if SCN is responsible for the most recent season’s low yields and if you need to develop a SCN management plan for next season. University experts say the best way to handle SCN is with an integrated and diverse management program. In addition to planting SCN-resistant soybean varieties and rotating them with non-host crops, like corn or alfalfa, you can use a seed-applied nematicide to protect soybean yield potential. Syngenta recommends growers plant seed treated with Clariva® Elite Beans seed treatment, an easy-to-handle premix of Clariva® pn nematicide and CruiserMaxx® Vibrance® seed treatment, which provides lethal activity against SCN all season long Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Tips to Maximize Your Soybean Harvest

SyngentaAgronomy — Tue, 17 Oct 2017 23:46:09 +0000

The weather is getting cooler and soybean pods have turned to their mature tan color. Here are several tips to keep in mind:

Monitor moisture levels: According to North Dakota State University, the ideal seed moisture to harvest soybeans is 13%. If you harvest when the moisture is too low, you can lose percentages of your yield and your bottom line. Growers should begin harvesting at 14 or 15% moisture level.
Check combine settings frequently and change as needed to specific field characteristics: Iowa State University Extension says proper combine settings will maximize quality while minimizing machine field losses. Take time to adjust the settings one by one to change things like the cleaning fan speed, sieve openings and cylinder speed.
Harvest when the weather is optimum: Be aware of varying moisture levels, which can increase or decrease based on the weather and time of day, such as overnight dew or high wind conditions. It’s also best to avoid harvesting during a hot afternoon when the beans are driest, to reduce shattering loss.
Use a harvest aid when appropriate: Using a herbicide like Gramoxone^® SL 2.0 can help increase combine efficiency and speed, while decreasing equipment wear and tear. Gramoxone SL 2.0 keeps the combine running smoothly by reducing foreign matter and controlling weeds, and it also stays effective in cool, wet conditions.

Harvest Report: Six-Generation Farm Thrives with Proactive Southern Rust Control

SyngentaAgronomy — Wed, 18 Oct 2017 21:48:01 +0000

Patrick Daugherty, Banock Farms (Morgantown, KY) KENTUCKY – Banock Farms, established in 1875 by Van Buren Daugherty - the great grandson of an Irish immigrant - has been passed down 6 generations. Current owner, Patrick Daugherty, has continued to adopt the latest crop protection innovations to continue the farm’s success. Located in the river bottoms of Morgantown, KY, and consistently dealing with excessive moisture, the farm’s corn regularly experiences heavy disease, and means fungicide choice can make or break their yields. This season, when Daugherty heard reports of Southern rust in a nearby county, he immediately applied Trivapro® fungicide – at tassel - before the disease had time to spread to his farm. Trivapro also prevented diseases like gray leaf spot from infecting his corn crop this season. Daugherty shared he has become a true fungicide believer. Although he is only a quarter of the way through harvest, he has already seen an average yield bump of 15 to 17 bu/A with Trivapro. Daugherty plans to stick to using Trivapro on all of his corn acres next year. The performance has proved to pay back all of his fungicide input costs, and then some. Daugherty said he knows hard work when he sees it, and Trivapro has proven to work hard for him, helping to grow Banock Farm’s legacy of success.

Modern Corn Roots Bred to Meet Soil Needs

SyngentaAgronomy — Wed, 18 Oct 2017 22:40:25 +0000

NK has classified its corn germplasm pool into three distinct root systems due to the genetic diversity within the NK seed lineup. These three types are classified as penetrating, fibrous and modified roots, and when placed in the correct environment, can maximize hybrid performance. Here are several examples of how to properly align root and soil structures:

A poorly drained soil combined with a corn-on-corn rotation would benefit from a hybrid that has a penetrating to modified root type. Penetrating roots are able to move further through the depths of the plate-like soil structure.
In comparison, a coarser soil that doesn’t hold water as well may benefit from the fibrous to modified root type. This is because fibrous root types consume nutrients and moisture near the soil surface to provide a broader footprint under the corn plant that helps maximize water and nutrient uptake.
The modified root structure brings the best qualities of the penetrating and fibrous root types together, as pictured above at the Stanton, MN, Grow More™ Experience site.

Historically, Minnesota growers plant modified to penetrating root types in the higher organic matter soils across the northwestern Red River Valley, central and southern parts of the state. More modified to fibrous root types are typically placed in the north and eastern parts of the state where soils may be coarser in texture. This is a bit contradictory to the general pattern of the U.S. where penetrating roots are traditionally planted the eastern half of the U.S. due to poor soil drainage, and fibrous roots are often planted in western, drier states for faster water consumption when it does rain. Ideally, root structures would penetrate the soil while also having fibrous characteristics that enable enough space for water and nutrient consumption. That’s why modern corn hybrids are being bred to contain properties from both fibrous and penetrating root types, to help meet evolving hybrid needs. To find out which root structures are right for your fields’ soil types, contact your Syngenta representative or NK^® Retailer with questions or for additional agronomic insights.

Tips for Delayed Winter Wheat Planting

SyngentaAgronomy — Fri, 27 Oct 2017 15:20:55 +0000

For many growers in the western High Plains, dry conditions followed by excessive rain has delayed wheat planting. Planting after optimum planting dates can lead to delayed plant establishment heading into winter and less tiller development into spring. Despite the risks of postponed planting, wheat growers can still increase their chance of a successful season by utilizing the appropriate management strategies:

Seeding rate adjustments: Increase seed rates by 10% overall, or by 1% for each day after the optimum planting date with a maximum 20% increase.
Fertility: Band phosphorus fertilizer with the seed when planting in cooler, wetter soils. This helps wheat become established as soon as possible and results in quicker emergence and growth.
Seed depth: Plant the seed at an appropriate depth to help protect it from cold and desiccation in the winter. Planting at a depth of 1.5-2” allows the crown to establish at the desired 1” below the soil line.

AgriPro brand winter wheat variety SY Monument has a high tillering ability and compensates for less heads per acre In addition to these planting guidelines, growers should consider their variety selection. AgriPro® brand winter wheat variety SY Monument is an ideal variety for delayed planting. SY Monument features good winter hardiness, which can help smaller seedlings make it through winter, and the ability to produce tillers late into the spring. In thinner stands, SY Monument can also increase the number of spikes per head, seeds per spike and weight per seed.

Beware of Caterpillars in Brassica Crops

SyngentaAgronomy — Fri, 27 Oct 2017 22:30:27 +0000

As growers start planting brassica crops, understanding pest pressures becomes increasingly important. Caterpillars can cause significant damage to brassica, so knowing what to look out for and how to handle these insects is a must this season. When looking for caterpillars, some common species include:

Ear armyworms
Cabbage loopers
Cabbage white butterflies

When these species feed, crops can become overrun. These pests come from moths, so it is important to recognize control options that deter them from laying eggs. Using a pest exclusion system like a lightweight fabric can lock moths out of crops, lessening their ability to reproduce and grow caterpillar populations. If looking for an insecticide as a solution, we recommend Besiege®, a broad-spectrum foliar insecticide that provides control against lepidopteran, sucking and chewing pests.

Monitor Western Bean Cutworm Levels: The Insect Overwinters

SyngentaAgronomy — Wed, 01 Nov 2017 17:21:19 +0000

Three of the most overlooked broad lepidopteran insects Minnesota farmers might face in a season are corn earworm, black cutworm and Western bean cutworm, which caused the damage pictured above. The reason these pests “might” be a problem is because corn earworms and black cutworms make their way from the southern U.S. states and don’t always reach a treatment threshold. Unlike corn earworm and black cutworm, Western bean cutworm overwinters in the Minnesota soil, and therefore the pest may be a developing threat to a corn crop. So if you’re trying to determine whether planting an insect-traited hybrid is a valuable investment, consider how much insect pressure your field faced this season. If Western bean cutworm was prevalent, unfortunately it’s likely the insect will cause more problems in 2018. If that’s the case, planting a traited hybrid would most likely be a worthwhile investment. The Stanton Grow More^™ Experience site conducts annual trials to determine the yield difference between a non-insect traited hybrid and one with the Agrisure Viptera^® trait. Trait stacks with Agrisure Viptera control up to 16 above- and below-ground insects, including Western bean cutworm, black cutworm and earworm. Stanton trials showed up to a 22 bu/A yield difference between the conventional hybrid and Agrisure Viptera traited hybrid, while the average increase was 5-6 bu/A. Reducing insect-caused ear damage that can lead to mold and mycotoxins also leads to higher-quality grain and peace of mind. Consider planting a traited hybrid in 2018 if Western bean cutworm affects 5% or more of your crop, because it’s likely the insect will overwinter and cause more problems next season. To learn more about hybrids available with Agrisure Viptera trait stacks, speak with your NK^® sales representative or NK retailer.

Learn to Combat Cotton Defoliation

SyngentaAgronomy — Fri, 03 Nov 2017 21:15:56 +0000

Wet conditions in October accelerated the spread of late-season disease, specifically alternaria leaf spot, in Texas cotton. The disease causes browning or bronzing of the leaves and can lead to premature defoliation. While cotton fields in the High Plains and Rolling Plains may appear to be in bad shape due to these symptoms, Texas A&M AgriLife Extension Service experts say that the mature state of the crop in affected areas should help limit affect to yield. However, if the epidemic would have occurred earlier in the season, growers may have observed greater yield loss. Therefore, growers are encouraged to monitor and keep record of the problem areas within fields so preventive measures can be put into place next season. Preventive measures include:

Incorporate cotton residue and/or rotate to alternate crops
Ensure proper soil fertility, especially potassium
Reduce plant stress through adequate drainage and other cultural practices
Minimize rank vine growth to help prevent excessive humidity in the crop canopy
Implement a preventive disease management program

To complete your arsenal, we suggest Quadris® fungicide, which offers broad-spectrum control of foliar cotton diseases, including alternaria leaf spot. Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Control Your Toughest Weeds With a Tough Herbicide

SyngentaAgronomy — Tue, 07 Nov 2017 22:56:25 +0000

Caption: A side-by-side comparison of active ingredients at the Traer, IA, Grow More Experience site shows a difference in residual control. Foxtail, lambsquarters, waterhemp and marestail are some of the most common weeds found in IA, and also the most difficult to control. Growers hunt each year for the next great solution against these tough weeds. And while growers may find a herbicide that provides control, not all herbicides provide effective, season-long control. A Grow More™ Experience site located in Traer, IA, conducted a study on the importance of using multiple, effective herbicide modes of action. The result? Herbicides with more effective modes of action deliver greater control of tough weeds, while herbicides with fewer effective modes of action can lead to escapes and more problems with resistant weeds. Acuron® corn herbicide and Resicore® herbicide both contain 3 modes of action. But these modes of action have different levels of effectiveness depending on the target weed they’re trying to control. When compared to clopyralid, an active ingredient in Resicore, bicyclopyrone, an active ingredient in Acuron, delivers more powerful control of large-seeded broadleaf weeds. Want to see for yourself?

Knock Out Soybean Weeds Before They Reach 4 Inches

SyngentaAgronomy — Tue, 07 Nov 2017 23:20:00 +0000

Caption: Control weeds in your soybean fields before they reach 4 inches – a height even shorter than most cell phones. Weeds like waterhemp and Palmer amaranth can grow up to 1 inch per day. This rapid growth rate makes post-emergence herbicide application timing crucial. If you spray a weed taller than 4 inches, it’s more likely to survive the herbicide application and continue growing. This leads to resistance to that herbicide and/or its active ingredients. The University of Minnesota Extension says post-emergence herbicides are most effective when applied to small weeds that are actively growing. Application to larger weeds may result in poor weed control and increased crop injury. Virginia Tech University says to spray before weeds reach 4 inches in height because dealing with larger weeds will accelerate the development of herbicide resistance, resulting in less weed control and decreased yield potential. Applying a post-emergence herbicide, such as Flexstar^® GT 3.5, before weeds can hit 4 inches can help preserve the efficacy of the herbicide application and reduce the chance of resistance building to the active ingredients.

Tough Weeds Need Effective Solutions

SyngentaAgronomy — Wed, 08 Nov 2017 23:17:14 +0000

Caption: A full rate of Acuron applied to bare ground at the DeKalb, IL, Grow More Experience site. Growers know that weeds rob corn yields and threaten the vitality of any farming operation. And while growers search for the next great weed management solution each year, few solutions seem to effectively manage tough weeds like giant ragweed, Palmer amaranth and waterhemp. But it isn’t always about finding the “next great” management solution. Often, it’s about choosing the right management solution customized to defeat the toughest weeds in your field. Our agronomist at two Grow More™ Experience sites, located in DeKalb and Pontiac, IL, recently conducted trials to show the importance of using multiple effective modes of action on two of Illinois’ most notorious weeds: giant ragweed and waterhemp. Weeds like these need a tough solution containing bicyclopyrone, the newest herbicidal active ingredient on the market, to deliver effective control. Bicyclopyrone was designed to complement mesotrione, and these two HPPD-inhibitors work together to deliver even more powerful weed control. After more than 60 days, Acuron® corn herbicide delivered greater, longer-lasting residual control compared to other herbicides, including Resicore® herbicide.

Protect Your Corn Hybrids From Western Bean Cutworm

SyngentaAgronomy — Thu, 09 Nov 2017 16:23:53 +0000

Western bean cutworm (WBC) is a growing threat that creates challenges for growers across the Corn Belt. Growers may find it arduous to scout for WBC as infestations may be difficult to predict and egg masses can be hard to find. Once WBC larvae hatch, treatments must be accurately timed in the narrow window available before larvae enter the ear. Infestations can occur in multiple areas of a field over the span of several weeks and require several scouting visits and treatments. Moths lay masses of up to 200 eggs in the upper leaves of corn plants. The eggs mature quickly, turning from white to tan and then purple before hatching within a few days. The hatched larvae feed on tassels, pollen, and silks before they chew holes through the ear husk and devour developing kernels. Once the larvae have entered the ear, insecticide treatments can’t easily penetrate the corn husk to reach the insect. In addition to yield reductions, kernels damaged by insect feeding are left vulnerable to mold and mycotoxin development (including aflatoxin and fumonisins), leading to decreased grain quality, lower profits, and potential harm if fed to livestock. Damaged grain with mycotoxins such as aflatoxin or fumonisins may result in dockage when marketing grain, resulting in less income for growers. Agrisure Viptera® is the only trait on the market that effectively helps control WBC, reducing feeding damage to ears and can minimize the resulting mold and mycotoxin development that would have entered insect-damaged kernels. Agrisure Viptera trait stacks offer growers better crop stand and lower levels of disease, helping to increase yield and profit potential. Caption: Agrisure Viptera performs under WBC pressure all season long Trait stacks available with Agrisure Viptera include Agrisure Duracade® 5222 E-Z Refuge®, Agrisure Viptera 3220 E-Z Refuge, Agrisure Viptera 3111, and Agrisure Viptera 3110.

Three Factors for Successful Corn Seed Selection

SyngentaAgronomy — Fri, 10 Nov 2017 00:34:14 +0000

A successful season starts with the seed selection process. With a wide choice of hybrid and trait options available, narrowing them down can be a difficult task. However, selecting the right hybrids for your farm and fields is not a decision a grower can take lightly and sets the performance potential for the entire growing season. To find the best fit for your field, consider these 3 factors when selecting hybrids:

Look for stability: You should select consistent, high performing hybrids that provide agronomic stability and withstand the rigors of a growing season. Keep an eye out for hybrids that consistently perform well across different locations. Hybrids with broad adaptability will likely reflect that consistent performance in your fields.
Consider yield ratings: Next, finding a high-yielding hybrid is key. Bob Nielson, Purdue University Extension agronomist, recommends searching for hybrids that yield 5% above the average yield. For example, if the average yield in your area is 175 bu/A, you would look for hybrids yielding a minimum of approximately 184 bu/A. Nielson also recommends selecting hybrids that consistently yield at least 90% of the highest yield in a trial. Narrowing your selection to a group of stable, high-yielding performers will have a direct correlation on your fields’ performance results.
Determine appropriate trait stacks: Trait stacks can address a wide array of problems, offering insect control, water optimization, herbicide tolerance and more. Selecting traited hybrids that fight against issues you’ve seen in your fields can help your corn thrive. While no 2 seasons are the same, identifying hybrids with the right traits for your fields can have a huge impact on your long-term success, and peace of mind.

The overall goal when selecting seed is to find a consistently high-yielding hybrid that fits your field’s needs. For recommendations on the best seed for your fields, contact your local NK^® sales representative or NK retailer.

Tackle Weeds with Powerful Control

SyngentaAgronomy — Fri, 10 Nov 2017 00:52:20 +0000

Caption: Acuron followed by Acuron at the Morgan, MN, Grow More Experience site. Many household products list a slew of chemicals that may not offer much meaning to the consumer. The same goes for a herbicide’s list of active ingredients. Thiencarbazone, clopyralid, flumetsulam: each of these active ingredients is listed in several corn herbicides -- but do you really know what’s in your herbicide and how it performs in your field? Individual active ingredients in a herbicide work together to deliver weed control. But not all active ingredients work together to deliver long-lasting residual weed control. Bicyclopyrone, mesotrione, S-metolachlor and atrazine: these four active ingredients contain unique physical properties that work together in a premix called Acuron® corn herbicide. Physical properties, including water solubility and soil absorption, are key factors that determine a herbicide’s effectiveness. Bicyclopyrone, the newest herbicidal active ingredient on the market, is particularly unique. Under extreme conditions, bicyclopyrone is readily available for the weed to uptake because of its water solubility. And with its good soil absorption, bicyclopyrone holds on to soil and organic matter so weeds can uptake Acuron. At a Grow More™ Experience site, located in Morgan, MN, the active ingredients in Acuron were tested against the active ingredients in other herbicides to show the efficacy of each active ingredient. The result? More powerful weed control with Acuron and its individual active ingredients.

Pair Soybean Traits with Your Weed Control Plan

SyngentaAgronomy — Fri, 10 Nov 2017 01:20:50 +0000

When it comes to selecting soybean varieties, growers are faced with more choices than ever. Advanced genetics contain more options for managing weeds, and NK varieties offer Roundup Ready 2 Yield^®, Roundup Ready 2 Xtend^® and LibertyLink^® traits. To help determine which traits are the strongest fit for your fields, consider the weed pressure on your farm and your plan for managing weeds. If your weed pressure is manageable with pre- and post-emergence residual herbicides, the Roundup Ready 2 Yield system may be the best option because it provides a foundation for success to control challenging and late emerging weeds. Along with consistent weed management, Roundup Ready 2 Yield varieties offer proven genetics, strong agronomic characteristics and varietal placement knowledge. In situations with difficult to control to control glyphosate-resistant weeds where pre- and post-emergence residual herbicides are lacking effectiveness, the Roundup Ready 2 Xtend and LibertyLink varieties offer different modes of action that may be a more effective weed management route. With Roundup Ready 2 Xtend soybeans, you can incorporate approved dicamba formulations into your weed control program. Roundup Ready 2 Xtend soybeans contain the Roundup Ready 2 Yield trait technology stacked with a trait that provides tolerance to dicamba. The LibertyLink system is a unique market alternative to glyphosate-tolerant systems. It combines Libertyherbicide and the LibertyLink trait as the only nonselective soybean weed control. Liberty herbicide controls over 120 broadleaf weeds and grasses, including ALS- and glyphosate-resistant weeds. So far, there hasn’t been any documented weed resistance to Liberty. For more details, the chart below summarizes the technology of all three trait systems: Being equipped with additional herbicide tolerance modes of action offers improved control over resistant and other tough-to-control weeds.

Identify Field Disease History Before Choosing Soybean Varieties

SyngentaAgronomy — Tue, 14 Nov 2017 00:21:03 +0000

With the end of harvest in sight, it’s time to review this season’s crop performance to help decide what to plant next year. The disease pressure your soybeans experienced in 2017 should be a key indicator for selecting the varieties that will perform their best on your farm in 2018. If your soybeans battled sudden death syndrome (SDS), they’re not alone. This common threat attacks the roots and stems of the plant, causing significant yield reduction. Because it is difficult to detect the disease until after the beginning of flowering, it’s important to know which fields were previously affected. If the soil is compromised, the disease can spread far and wide. Another common soybean disease is frogeye leaf spot. The disease leaves reddish brown spots on affected soybean pods, with the fungus traveling through the outside wall and infecting the mature seeds. If the infection is severe enough, yields can decrease. Seed selection can go a long way toward protecting your yield. Two varieties that performed particularly well against these diseases this season were NK® soybeans S43-V3X and S48-R2X brands, with the former averaging nearly 5 bu/A more than Asgrow® brands across 36 trials throughout the Delta and Southern Plains. Both varieties yield well across various soil types and exhibit solid SDS and frogeye leaf spot tolerance.

Four Tips for Choosing Your Wheat Seed

SyngentaAgronomy — Thu, 16 Nov 2017 00:41:24 +0000

As fall harvest wraps up, now is a good time to review the successes and struggles of this past season to determine how to improve in the season to come. When looking at seed selection, choosing a strong wheat variety can increase both yield potential and stability, leading to a potentially better harvest. There are several things to consider when choosing your preferred seed:

While high yield is a factor, choosing stable varieties that can perform consistently in different environments throughout the years is important.
Look at summarized data of the past few years, which can help you understand the risks and benefits of your selected seed.
Choose the variety that, on average, performs the best at locations near your farm during the past several years.
If planting is delayed past optimum planting dates, consider a variety that will offer strong winter hardiness and the ability to produce tillers late into the spring.

AgriPro® brand wheat varieties are strong performers that consistently rank in the top yield group in every region in North America. These varieties offer best-in-class disease packages, leading agronomics, outstanding yields and high end-use quality. To learn more or to find a local AgriPro Associate, visit www.agriprowheat.com.

Practices to Avoid When Dealing with Lodged Corn

SyngentaAgronomy — Fri, 17 Nov 2017 00:23:27 +0000

Stalk rot vs. healthy stalk. From challenging weather to unwanted pests and disease, conditions this season have led to stalk lodging for many corn growers. Severely lodged corn can put yield potential at risk, so it is important to be mindful when harvesting lodged corn. To help you get the most out of every row, here are several common mistakes to avoid:

Waiting too long: Lodged corn should be harvested first, as delaying harvest leaves the crop at risk for worsening stalk rot.
Not testing the field: Take the time to properly assess your situation and measure potential losses. Combine through a lodged area and note the number of ears left behind the combine. If ear loss is extreme, walk through a similar unharvested area and count the number of ears already on the ground. These ears are not likely to get picked up regardless of head adjustment.
Speeding through harvest: Rushing quickly through your fields is inefficient for lodged corn. Slow your combine speed to reduce the risk of missed ears, and be sure to go against the grain to diminish loss.
Neglecting safety: Iowa State University Extension warns that when dealing with lodged corn, harvest is not business as usual. It’s easy to get frustrated with the time and effort required, but proper safety practices are mission critical. Rushing through harvest can be dangerous and counterproductive.

Still Harvesting? Here’s the Risk

SyngentaAgronomy — Fri, 17 Nov 2017 19:55:17 +0000

Although rarely within our control, delays in corn harvest can have a serious effect on yield potential. When left in fields past mid-November, crops become increasingly exposed to unfavorable weather conditions, not to mention wildlife and the threat of disease damage. Corn hybrids with weak plant integrity face a particularly high chance of sustaining losses through stalk lodging and ear rot, affecting marketable yield. Understanding the variables around corn harvest is important for maximizing return on investment. An Ohio State University Extension study of harvest delays offered several key insights:

Harvest delays that occurred beyond mid-November accounted for nearly 90% of yield loss.
Increase in stalk rot appeared between harvest dates in October and November. By comparison, increases in stalk lodging occurred primarily after early to mid-November.
Hybrids with lower stalk strength ratings exhibited greater stalk rot, lodging and yield loss when harvest was delayed.

While we can’t stop weather from causing delayed harvests, these findings show that selecting corn hybrids with certain agronomic characteristics – like the higher stalk strength ratings found in the NK® corn portfolio – can help to minimize its overall impact.

How Plant Population Impacts Yield

SyngentaAgronomy — Fri, 17 Nov 2017 20:35:35 +0000

Caption: Stress wheel demonstrates different row spacing at the Syngenta Grow More™ Experience site in Stanton, MN. Growers are always working to maximize yield - experimenting with different hybrids, traits and management practices to find what best suits fields. Often, increasing plant populations is a method growers use, with the idea being more seeds per acre means more plants with harvestable ears and consequently more yield. This can be true for some hybrids, but not all. Each hybrid has a different response to population density. To display the effects of density on hybrids, the Syngenta Grow More™ Experience site in Stanton, MN, featured a “stress wheel” in 2017. This demonstration is a hand-planted plot of different hybrids at altered plant populations and row spacings. The plant populations ranged from 28,000 to 50,000 kernels per acre. Planting hybrids at varying row spacing demonstrates how population can affect stalk quality, ear retention, lodging, roots and ultimately, yield. It was clear from the stress wheel results that not all hybrids are equipped to handle high populations. As population increased, some hybrids, particularly determinant ear types, faced weakened stalk strength and standability. When using these products, be cautious when increasing plant population. In general, yield increases resulting from higher plant populations are primarily due to more plants per acre capturing sunlight during the growing season. If plants become too crowded, they have smaller root systems and smaller stalks, resulting in poor standability and lower yields. On the other hand, some hybrids respond well to higher planting populations. Such hybrids held ear size fairly well and maintained ear count. For hybrids that respond well to increased population densities, traditionally ear flex products, planting higher populations can help you reach higher yields. When planning planting populations that are right for your fields and management style in 2018, contact your Syngenta representative or NK^® retailer with questions or for additional agronomic insights. Population recommendations are provided for all NK hybrids. Sign up for the Know More, Grow More Digest to receive twice monthly agronomic e-mail updates pertinent to your area.

Corn Hybrids Offer Improved Feedlot and Dairy Operations

SyngentaAgronomy — Mon, 20 Nov 2017 19:30:07 +0000

When growing corn to be fed on-farm for a beef or dairy operation, selecting a hybrid that provides value in the field and in feed is a simple way to improve profit potential. Energy is key to maximizing beef or dairy production and corn is an important energy source for cattle because it supplies starch, which is converted to sugar during digestion. Enogen® Feed hybrids help convert starch to sugar more efficiently and more rapidly during digestion, resulting in more available energy for cattle and ultimately greater profit potential for feedlot and dairy operations. In the field, Enogen Feed corn performs equal to or better than other high-performing corn hybrids¹, with no additional agronomic management challenges², unlike some silage-specific hybrids. Additionally, it offers producers the flexibility to chop for silage or harvest for grain. Incorporating these hybrids into your operation is as easy as replacing the corn or silage you currently grow and feed. Enogen Feed hybrids represent a step-change in starch and sugar availability.

Burndowns Can’t Always Withstand Cold Temperatures

SyngentaAgronomy — Wed, 22 Nov 2017 18:34:11 +0000

As harvest wraps up, prepare for next season with a burndown herbicide. As you start to plan ahead for planting next season, you’ll also need to prepare for pre-season weed control. While burndown herbicides will clear weeds already in your fields, winter temperatures can affect the efficacy of fall burndown herbicide applications. The effect of cool weather on weed control can vary depending on the target weed, herbicide used and rate of application. For weeds like waterhemp and Palmer amaranth, a fall application will not help with control, as these weeds do not emerge until May. For marestail, a fall application may be critical for optimum weed control. The University of Nebraska Extension says most marestail in Nebraska is fall-emerging and is better controlled in the fall when the weed is still young. The ideal temperature for applying most post-emergence herbicides is 65 to 85 degrees Fahrenheit. Herbicides can still be effective when applied at 40 to 60 degrees, but they will take longer to work as the cooler weather slows down the absorption rate. If it is below 40 degrees or cloudy for a period of time after the application, weed control will most likely be reduced. Frost can also impact the efficiency of burndown herbicides. Frost damage puts weeds under stress, which makes them poor targets for herbicide application. After frost, you should wait a few days for active growth and new leaf tissue to begin applying the burndown herbicide. According to the Purdue University Extension, winter weeds, like purple deadnettle, can serve as an alternate host to soybean cyst nematode, the top U.S. soybean pest. Scout fields now for winter annual weeds and remove them prior to planting. Sign up for the Know More, Grow More Digest to receive twice-monthly agronomic e-mail updates pertinent to your area.

Three Tips To Consider For Controlling Weeds In Winter Wheat

SyngentaAgronomy — Wed, 22 Nov 2017 19:22:39 +0000

Growers who plant winter wheat must consider several factors that could prevent them from a successful harvest in the spring. From less-than-ideal weather conditions to weed resistance, staying ahead of potential problems is key to protecting yields. Here are 3 tips to consider when planning an herbicide program for winter wheat:

Plan ahead for difficult weeds: To fight against resistant weeds, it’s essential to use herbicides with multiple effective modes of action. Growers should consider Talinor™ herbicide for post–emergent weed control. It contains bicyclopyrone (group 27) and bromoxynil (group 6) which are proven to be effective in controlling difficult broadleaf weeds.
Consider tank mixing: An appropriate tank mix can save growers time and labor costs. Talinor is an excellent tank-mix partner with Axial® XL or Axial® Star herbicides for additional modes of action and one-pass control of yield-robbing broadleaf and grass weeds.
Outsmart unpredictable weather: Growers know that weather has a huge impact on yields and crop quality. Choosing a herbicide with a wide application window and superior rainfastness gives growers application flexibility. Talinor is formulated to allow it to be quickly and thoroughly absorbed by plant tissues before irrigation or rain can cause product loss.

Continue to Maximize ROI After Harvest Ends

SyngentaAgronomy — Tue, 28 Nov 2017 18:42:56 +0000

It can be tempting to think of the season as complete after the combines are done rolling, but post-harvest grain management is almost as important as harvest itself. Proper grain drying, cooling and storage will all help to preserve and protect return on investment. Here are a couple of key considerations:

Make sure grain is completely dried to an appropriate moisture level: Regardless of whether you air dry or use a dryer, it’s crucial to dry grain quickly and thoroughly to prevent mold development. Dryer temperatures can vary, so it’s important to monitor moisture levels to help ensure that grain dries evenly. Wet corn above 15.5% moisture stored in a grain bin without aeration can lead to molding or hot spots within the bin if not monitored periodically.
Closely monitor grain temperature: This is key for maintaining grain quality. Once stored, check grain at least every 2 weeks, aerating every so often to match grain and air temperatures. Lower grain temperature gradually in the fall, and keep it cold in the spring.

Improper drying and/or storage can lead to the development of mycotoxins such as aflatoxin that can ultimately decrease the quality and shelf life of grain.

Fighting Back: Managing Resistant Broadleaf Weeds in Cereals

SyngentaAgronomy — Fri, 01 Dec 2017 20:38:42 +0000

With weed resistance continuing to sweep across U.S. wheat and barley fields, growers must find new ways to combat weeds that rob their yields and profits. Growers are finding that particularly troublesome broadleaf weeds are showing resistance to ALS-inhibitor, synthetic auxin and glyphosate herbicides. Growers should plan their 2018 herbicide programs knowing that weed resistance will be an ongoing issue. It is key to plan on using a herbicide that can be counted on for superior control of resistant broadleaf weeds. Talinor (front) controlled weeds in a North Dakota field where Huskie Complete (back right) failed to suppress kochia. After a strong first year on the market, Talinor™ herbicide has proven itself consistently effective against broadleaf weed biotypes that show resistance to other herbicides, with some growers finding that it outperformed competitors like Huskie® Complete. In 2017, Talinor was tested in 34 R&D trials and at 7 Grow More Experience sites across the U.S. that demonstrated excellent performance on broadleaf weeds such as lambsquarters, redroot pigweed, Russian thistle and hairy nightshade. Retailers and crop consultants reported excellent control of problem weeds like kochia, wild buckwheat and annual sowthistle.

Protect Corn Hybrids from Harmful Mycotoxins

SyngentaAgronomy — Mon, 04 Dec 2017 21:45:36 +0000

Insect management is key to a successful season, but scouting and treatment can be time-consuming and costly tasks. Without proper management, common pests like corn earworm or western bean cutworm can feed on corn ears, injuring corn kernels and allowing spores of ear molds to enter into the developing grain. These exposed areas leave the plant vulnerable to the invasion of ear molds and the development of aflatoxin and fumonisins, two very concerning mycotoxins. These mycotoxins can reduce the price received for grain at market or be potentially harmful to livestock if fed as silage, grain or DDGs. Aflatoxin is a known carcinogen, so the FDA mandates that levels cannot exceed certain limits, measured in parts per billion (ppb) depending on the intended use of the corn. The FDA has also set standards to regulate acceptable levels of fumonisin, which can be highly toxic to livestock and humans. Corn hybrid with Agrisure Viptera trait (left) vs. non-Agrisure Viptera hybrid (right) Fortunately, there’s an easy solution to help protect grain quality and profitability. Independent research has proven that the Agrisure Viptera® trait limits damage caused by insects, reducing mold growth and the formation of mycotoxins, helping you maximize yield potential and protect your bottom line. No other trait in the industry provides better or more complete control of more insects.

Early-season Showers Highlight Herbicide Value

SyngentaAgronomy — Fri, 08 Dec 2017 20:19:29 +0000

Ohio City, Ohio: Heavy, unexpected rainfall during 2017 planting made timing herbicide applications stressful, and the weed pressures that followed didn’t help either. Our Syngenta agronomists helped area growers overcome these challenges. Below are two of those stories. Grower Mark Keber attributed the early giant ragweed and marestail pressure in his fields to the unusually wet conditions, which delayed herbicide application past the recommended pre-emergence timing. Unable to apply his herbicide pre-emergence, Keber had to wait until post-emergence. By then, giant ragweed and marestail were already up and gaining a foothold in his fields. Caption: Acuron 3 qts/A with 32 fl oz/A glyphosate in grower Mark Keber’s field. Photo taken 43 days after application on June 30, 2017. Just down the road, grower Dave Allmandinger’s concerns revolved around residual control. Allmandinger applied his herbicide following the planter but had to replant some of his popcorn up to 4 times. He worried that the residual would not control the cocklebur, velvetleaf and grasses in the later-planted fields until canopy. Caption: Acuron 3 qts/A in grower Dave Allmandinger’s field. Photo taken 63 days after application on June 30, 2017. Both Keber and Allmandinger applied Acuron® corn herbicide in their fields and had noticeably clean fields after application and through canopy. Acuron combines 4 active ingredients and 3 effective modes of action (Groups 5, 15 and 27) for long-lasting residual control and built-in weed resistance management. A wide window of application, from 28 days pre-plant up to 12-inch corn, also provides flexibility when early-season rains delay planting and herbicide application.

Soybean Seed Treatment: A Necessity in 2018

SyngentaAgronomy — Mon, 11 Dec 2017 17:46:43 +0000

As you begin making plans to put your soybeans into the ground, there is a lot to take into consideration: What type of disease pressures could impact my soybean crop this season? Is this likely to be a wet or dry year? Should I even consider using a seed treatment at all? When thinking about seed treatments, consider the facts:

A University of Iowa study revealed that fungicide seed treatments allow you to plant earlier in the season when soil may be cool and damp, while still avoiding early-season damping-off diseases, such as Pythium. Researchers have found that early planting can contribute to increased yield.
A 10-year study conducted by scientists at 4 universities found that soybeans treated with neonicotinoids boosted yields by 3 to 5%. This class of insecticides can control insects like soybean aphid, bean leaf beetle, grape colaspis and leafhopper.
The University of Wisconsin found that treated seeds could yield $17 per acre more profit than untreated seeds.

Since not all seed treatments are created equal, it’s not enough to treat your seeds with just any treatment – it’s important to select the right one. We recommend using a treatment with multiple active ingredients because of the diverse set of pathogens in the soil. CruiserMaxx^® Vibrance^® Beans seed treatment, a combination of separately registered products, helps optimize root health, provides stress tolerance, and improves plant vigor for better emergence to maximize yield potential each season.

Four Questions to Ask Yourself When Selecting Soybeans

SyngentaAgronomy — Tue, 12 Dec 2017 21:38:13 +0000

Most seasons start with a simple goal: make a profit. As you look back on 2017 to determine which of your decisions were profitable for your operation and which weren’t, start by considering the seed. Finding the best fit for your fields can go a long way toward maximizing end-of-season results. If you’re a soybean grower in the thick of making 2018 seed selections, be sure to ask yourself these questions:

What soil type(s) do I have on my farm?

Not only are soil types different from region to region and farm to farm, they can differ from field to field. Variety performance can be impacted greatly by the soil type, so make sure you know what textures, pH levels, etc. you’re working with before deciding on your seed varieties.

Am I doing enough to combat disease?

If your soybean fields have suffered from back-to-back years of yield robbers like sudden death syndrome or white mold, it may be time to consider switching to varieties with better built-in disease tolerance. Syngenta agronomists recommend looking at the most recent 3-5 years of a field’s disease history, then seeking out varieties rated highly against the diseases you’ve repeatedly encountered. Many NK® soybean varieties offer high tolerance ratings against a range of critical diseases.

Will I be ready for Mother Nature?

Weather is unpredictable – that’s a given every season. Fortunately, you can minimize its impact and maximize yield potential by spreading risk. Diversify your seed portfolio and include varieties that will perform well even with water or weather stress. Also make sure to look for varieties with relative maturities that are right for your local environment.

What is my management plan for next season?

Don’t forget that factors like planting population, crop rotation and fungicide applications can all influence which varieties are best for your fields.

Indiana: It’s not unusual to find a variety of tough, herbicide-resistant weeds in southern IN. The White River continually carries weed seeds from northern IN into southern IN corn fields via its east and west forks, complicating efforts to fight resistance. Caption: Vallonia, IN: A foundation rate of 1.25 qts/A Acuron and 1 qt/A atrazine applied at planting on April 13 followed by the remaining 1.25 qts/A Acuron and 1 qt/A glyphosate in the middle of May. Photo taken June 29, 2017. In Vallonia, IN, 2 of the toughest weeds growers encountered in 2017 were marestail and Palmer amaranth. Further south in Charlestown, IN, growers saw a mixture of giant ragweed, marestail and Palmer amaranth. All 3 weeds aggressively compete with corn for nutrients, sunlight and water, making it vitally important to control them before they reduce yield potential.

Waterhemp Beware: Multiple Modes of Action Deliver Control

SyngentaAgronomy — Thu, 14 Dec 2017 23:52:25 +0000

Missouri: Growers in Clarksdale and Pattonsburg, MO, named waterhemp as one of their toughest weeds in corn. Waterhemp is difficult to control because it:

Germinates throughout the season
Grows up to one inch per day
Produces up to one million seeds per plant

Left uncontrolled, a few waterhemp plants can easily become hundreds or thousands of waterhemp plants in subsequent seasons. Caption: Clarksdale, MO: Acuron 2.5 qts/A with atrazine and glyphosate applied 17 days after planting on May 9. Photo taken 34 days after application on June 12, 2017. Managing difficult weeds like waterhemp requires herbicides with multiple, effective modes of action. Multiple, effective modes of action ensure that corn fields stay clean and remain clean throughout the season, protecting yield and the long-term viability and profitability of your farm. Caption: Pattonsburg, MO: Acuron 3 qts/A with atrazine and glyphosate applied eight days after planting on May 17. Photo taken 26 days after application on June 12, 2017.

Conquer the War Against Corn and Soybean Weeds

SyngentaAgronomy — Mon, 18 Dec 2017 18:51:54 +0000

Giant ragweed is one of the earliest emerging annual summer weeds If you were hoping for even a slight break after harvest… think again. You should already be thinking about what you can do next season to win the war against corn and soybean weeds. Syngenta recommends a threefold battle strategy:

Start clean: You should have already applied a fall burndown to wipe your fields clean. You may also need to apply a burndown in the spring to kill off any winter weeds, such as marestail. Early-emerging summer weeds, including giant ragweed, can also come up around this time if there was a warm winter.
Overlap residuals: If you think you need to wait until weeds appear to use herbicides, then the weeds are winning the war. Use a pre-emergence herbicide to fight weeds before they have a chance to emerge. Then, use an overlapping post-emergence herbicide to extend the length of control. If any weed escapes can be seen in your field, apply your post-emergence herbicide prior to any of them reaching 4” tall.
Utilize multiple effective modes of action: A study from the University of Minnesota found that continuous use of a product for over 2 years could develop an herbicide resistance problem. That’s why Iowa State University recommends utilizing multiple herbicide groups that are effective against specific problem weeds in the field.

The 4 Levels of Nitrogen Response Ratings

SyngentaAgronomy — Wed, 20 Dec 2017 20:27:54 +0000

Since not all corn plants respond equally to nitrogen, the amount needed to produce a healthy crop can vary greatly by hybrid. The NK^® agronomy team provides Hybrid Nitrogen Response Ratings as a resource to evaluate each hybrid, helping you understand what will work for your environment and management style. The 4 ratings for how hybrids respond to nitrogen are:

High: The hybrid responds to increased nitrogen better than most other hybrids, with a higher economic payback for the nitrogen investment made.
Moderate: The hybrid responds to increased nitrogen similarly to most other hybrids, so applying extra nitrogen or sidedressing should result in a noticeable yield difference.
Low: The hybrid responds to increased nitrogen less than most other hybrids, so making nitrogen investments wouldn’t deliver nearly as high of an ROI as the high or moderate ratings.
Very low: The hybrid responds considerably less than most other hybrids, so making additional or sidedress nitrogen applications would have very little economic benefit.

Soil type is another factor that can influence the availability and uptake of nitrogen by hybrids. Coarse textured soils have poor water and nutrient holding capacity, specifically nitrogen. This also means that cornfields planted on coarse-textured soils will typically experience a yield increase from adding additional nitrogen than fine-textured soils. Adding nitrogen or sidedressing a hybrid with a high nitrogen response rating would likely be recommended after a wet spring or particularly rainy spell. When choosing a hybrid for the 2018 growing season, keep in mind the nitrogen hybrid ratings, soil types and other management needs specific to your farm.

Identify Verticillium Wilt to Prevent Potato Early Dying

SyngentaAgronomy — Fri, 22 Dec 2017 16:28:01 +0000

Verticillium wilt is a disease caused by the soilborne Verticillium dahlia fungus, and is a major cause of potato early death. Identifying the fungus early can help ensure healthy fields and a high-yielding potato crop. The disease causes wilt, stunted plants, necrosis, and crop loss, but early identification can help growers avoid damaged crops in subsequent years. V. dahlia can live in soil for up to 15 years, with its effects worsening over time. Once the fungus is in a field, it is very difficult to control, so take preventive measures, such as planting resistant varieties. Controlling other host plants, planting clean seeds, and treating with fungicides can also help prevent Verticillium wilt. Elatus® fungicide can now be used under a 2ee recommendation to aid growers in the fight against Verticillium wilt. As the only in-furrow technology that contains a proven strobilurin and third generation SDHI fungicide, Elatus provides built-in resistance management. The disease control offered by Elatus can help improve emergence, establish a more uniform crop stand, enhance crop health, and optimize distribution of tuber size.

Start Clean in 2018: Manage Winter Weeds

SyngentaAgronomy — Fri, 22 Dec 2017 17:10:27 +0000

Marestail From crop establishment to seedling diseases and pests, there are several aspects of crop production that winter weeds impact each year. Controlling these difficult weeds is the first step in ensuring the best possible start for top yields. Some growers have moved away from pre-emergence residual herbicides and have eliminated tillage from their weed management programs. As a result, they may struggle to control winter weeds at planting. These weeds include marestail, common chickweed, field pennycress and more. One of the biggest issues with unmanaged winter weeds is their effect on timely planting. Purdue University researchers say weeds can also increase the likelihood of insect infestations and disease, like black cutworm and soybean cyst nematode. Fortunately, there are a number of cultural practices and management options that can help combat winter weeds:

Weed scouting and identification during harvest gives no-till producers a head start on combatting weeds.
In order to target the most vulnerable growth stage of winter annuals, University of Nebraska experts advise that growers should plan on a fall application of a pre-emergence herbicide.
Crop rotation reduces the likelihood that specific weed species will become adapted to the system, while aggressive tillage operations bury weed seeds, thwarting germination and emergence. Additionally, a spring burndown program provides effective weed control to prepare for planting.

Treat Your Soybeans for Higher Yields

SyngentaAgronomy — Thu, 04 Jan 2018 16:54:55 +0000

Many factors contribute to strong emergence and stand establishment in soybeans, but it begins with protecting your soybeans with a seed treatment. In order to reach the highest yield potential each season, soybeans need a layer of defense against early-season diseases and insects. If plants are infected or damaged at an early growth stage, the chance for good emergence and stand establishment decreases. The Iowa State University Extension says there are many benefits to planting treated soybeans. In order to turn a profit, planting high-quality seed is essential. After that, seed treatments can provide additional protection from major early-season diseases and insects, such as bean leaf beetles, Phytophthora and seed borne rot. Planting treated soybeans and good management are crucial for keeping these and other pests out of fields. The University of Minnesota conducted field crop trials and found that treated soybeans saw less disease incidence than untreated soybeans, and were therefore able to reach greater yields. This was the first year farmers were allowed to plant treated soybeans during the trial. For protection against damaging early-season insects and diseases, we recommend using CruiserMaxx^®Vibrance^®Beans seed treatment, a combination of separately registered products, and the only seed treatment that offers the unique RootingPower™ of Vibrance fungicide and the Cruiser^® Vigor Effect. Syngenta also offers Clariva^® Elite Beans seed treatment, an easy-to-handle premix of Clariva® pn nematicide and CruiserMaxx Vibrance seed treatment, and the only product on the market that provides season-long activity against soybean cyst nematode.

Watch for Marestail (Horseweed) In Corn and Soybeans

SyngentaAgronomy — Fri, 01 Dec 2017 22:41:08 +0000

Marestail Marestail, also known as horseweed, is a small-seeded broadleaf weed that typically emerges in the fall, although it can emerge in the spring and summer months. Like other small-seeded broadleaf weeds, marestail is a prolific seed producer. Since its seeds are small and light, they are easily transferred by wind, animals, human clothing and equipment that is not thoroughly cleaned. While marestail seeds thrive close to the soil surface in reduced-, minimum- and no-till situations, and are susceptible to herbicide applications, the number and mobility with which the seeds spread makes marestail a formidable, tough weed. In addition, marestail can cross-pollinate, further complicating efforts to stop resistance from spreading. Marestail facts:

One of the first glyphosate-resistant weeds identified in U.S. row crops
Produces up to 200,000 seeds per plant
Seeds are highly mobile and easily spread to new areas
Grows up to 6’ tall

Start clean and stay clean throughout the growing season with an application of Acuron^® or Acuron Flexi corn herbicides. Acuron has 3 effective modes of action (Groups 5, 15 and 27) and Acuron Flexi has 2 (Groups 15 and 27). Both herbicides contain bicyclopyrone, which is designed to complement the other active ingredients in the premix to deliver broader spectrum, more consistent control of tough weeds other products are missing. For soybean growers, Syngenta offers effective weed control programs that can start with Boundary^® 6.5 EC herbicide (Groups 5 and 15) for pre-emergence marestail control and long-lasting residual.

Gain Control of Morningglory

SyngentaAgronomy — Fri, 01 Dec 2017 23:30:11 +0000

Morningglory From robbing corn and soybean yields to remaining viable in soil for more than 50 years, morningglory is one of the toughest weeds to control. As with other large-seeded broadleaves, morningglory seeds are relatively large and when the plant emerges, it is often bigger than small-seeded broadleaf weeds. If left to compete all season, just 1 morningglory plant per foot of row can reduce soybean yields by 50%. Although there aren’t confirmed cases of herbicide resistance in morningglory, it is still difficult to control due to its large seed size and seed coat, its ability to germinate late in the season and its tolerance of glyphosate. Facts about Morningglory:

It favors warmer climates and is typically found in the South and central U.S.
It germinates in early summer and favors day temperatures around 85 degrees Fahrenheit
It can produce anywhere from 5,000 seeds per plant to more than 15,000
Its leaves are heart-shaped or lobed and range from 2 to 5” in length and 1.5 to 4” wide
They are a vining plants and have tendrils for climbing
The flowers are funnel-shaped and typically blue, purple or white

Syngenta offers best-in-class herbicides that provide effective multiple modes of action to control morningglory in both corn and soybeans. Acuron^® corn herbicide has 4 active ingredients and 3 effective modes of action (Groups 5, 15, and 27). Its atrazine-free counterpart, Acuron Flexi corn herbicide, has 3 active ingredients and 2 effective modes of action (Groups 15 and 27). Both contain the active ingredient bicyclopyrone, which complements the other active ingredients to deliver more effective and more consistent waterhemp control than competitive products. For optimal control, these brands should be applied before morningglory emerges. Acuron and Acuron Flexi can be applied alone or pre-emergence followed by a post-emergence application of Halex^® GT corn herbicide (Groups 9, 15 and 27). For soybeans, Syngenta recommends a pre-emergence herbicide application of BroadAxe^® XC herbicide (Groups 14 and 15) for early-season weed management and long-lasting residual control. For post-emergence control, Flexstar^® GT 3.5 delivers 2 different modes of action (Groups 9 and 14).

Know the Difference Between Waterhemp and Palmer Amaranth

SyngentaAgronomy — Sat, 02 Dec 2017 01:30:15 +0000

PPO-resistant waterhemp and Palmer amaranth are 2 of the biggest challenges corn and soybean growers face during the growing season. But when looking at these weeds, some would think they’re identical twins. Joe Wuerffel, research and development scientist at Syngenta, provides insight on how to tell the difference between them:

Waterhemp is primarily a Northern weed, while Palmer amaranth dominates the South.
Petiole length is key. Waterhemp has shorter petioles, the portion that connects the leaf to the main stem, while Palmer amaranth petioles are generally longer.
When looking down at the plant, Palmer amaranth leaves tend to fill out and cover the ground more so than waterhemp.
Waterhemp does not intercept as much light as Palmer amaranth, therefore, doesn’t grow as aggressively.
The flowers on waterhemp are best measured in inches, while the Palmer amaranth flowers and seed head are best measured in feet.
Unlike waterhemp, the female seed head on a Palmer amaranth plant is rough and has spikes that hurt to the touch.
At times, Palmer amaranth develops a watermark on its leaves.

Palmer amaranth is on the left, waterhemp is on the right. The best way to prevent pressure from both weed species is to implement an effective weed management strategy that includes pre- and post-emergence herbicides with multiple modes of action. Acuron^® corn herbicide has 4 active ingredients and 3 effective modes of action (Groups 5, 15 and 27). Its atrazine-free counterpart, Acuron Flexi corn herbicide, has 3 active ingredients and 2 effective modes of action (Groups 15 and 27). Both contain the active ingredient bicyclopyrone, which complements the other active ingredients to deliver more effective, more consistent weed control than competitive products. For optimal control, these brands should be applied before each weed emerges. Acuron and Acuron Flexi can be applied alone or pre-emergence followed by a post-emergence application of Halex^® GT corn herbicide (Groups 9, 15 and 27) plus AAtrex^® corn herbicide (Group 5). Syngenta also offers an effective soybean weed control program that starts with pre-emergence, long-last residual control from BroadAxe^® XC (Groups 14 and 15) or Boundary^® 6.5 EC (Groups 5 and 15) herbicide. In addition, a post-emergence application of Flexstar^® GT 3.5 delivers two different modes of action (Groups 9 and 14) to control resistant broadleaf weeds.

Sample Soil to Make Better Seed Decisions

SyngentaAgronomy — Fri, 05 Jan 2018 19:18:46 +0000

Before selecting 2018 hybrids and varieties, growers are encouraged to first conduct soil analysis tests. Knowing the pH levels of your fields is key to adjusting soil composition and starting strong before the season ever begins. That’s why for nearly 2 decades, Syngenta breeders have tested hybrid and variety responses to different pH levels. pH measures relative acidity or alkalinity of the soil, and soils typically range on a scale from 3.5 to 10, with the optimum target being from 6 to 7. Nutrients such as phosphorus, manganese and zinc become less available when pH exceeds 7.5. Here are the 3 different pH levels and what you can do about your test results:

Low pH: Soil acidity increases as pH drops below 7 (neutral pH), so if you see field results below 5.5, you may want to consider a lime application.
High pH: Soil alkalinity increases as pH rises above 7 (neutral pH), so in instances of field results above 7.8, usiing the proper combination and placement nutrients is important to aid in plant uptake. Varietal selection tolerant to high pH in both corn and soybeans is critical to a successful crop.
Ideal pH: Levels between 6 and 7 are optimum, so when your fields test within this window, you’re right where you should be.

Standardized testing is conducted in Nebraska 4 times a year on a 10-acre plot before NK® corn and soybeans are categorized for a particular pH level. All NK hybrids and varieties are measured alongside competitor products such as those from DeKalb and Pioneer. The 4 stages at which hybrids and varieties are measured for pH include: emergence, V5-V6 and twice during the reproductive stages. NK corn and soybeans are closely evaluated for target pH levels to help ensure the best product placement in your fields, which helps optimize plant health and yield. As for managing the pH levels on your own operation, collect soil samples from a depth of 6 to 8 inches every 2 to 4 years. Sampling soil 3 to 6 months before planting the next crop allows enough time to develop a nutrient plan to address what your pH might demand. Late fall or early winter is a great time to discover what is going on beneath the surface. As a rule of thumb, obtain 15 to 20 soil cores for an area of 20 acres or less, and clean your sampling instruments to avoid contamination as you go from one field location to another. Having an accurate overview of your fields’ pH levels will not only get you off to a strong start at planting, but also help you get through the season.

Extend the Life of SCN-Resistant Soybean Varieties

SyngentaAgronomy — Wed, 10 Jan 2018 17:57:45 +0000

Caption: Use nematicide seed treatments and crop rotation in addition to planting SCN-resistant varieties to control SCN. Soybean cyst nematode (SCN) is the most economically damaging soybean pest in the U.S., leading to yield losses as high as 30%. SCN causes extensive root damage, making plants more vulnerable to diseases such as sudden death syndrome (SDS).To protect your soybean fields from SCN, it’s important to manage it in multiple ways. Iowa State University says there are more than 1,000 varieties of SCN-resistant soybean seeds on the market, but there is little diversity within the genes. A whopping 97% of all varieties contain the same source of resistance – PI88788. This means only 29 out of those 1,000+ varieties have resistance from another source. Repeatedly growing soybean varieties with the same SCN resistance genes will increase the chances that SCN in your field will adapt to that gene. Researchers warn that PI88788 is becoming increasingly ineffective against SCN. To better manage SCN and extend the life of SCN-resistant seed genetics, an effective management program combines growing SCN-resistant soybean varieties with cultural practices, such as crop rotation, along with using a nematicide seed treatment. By rotating with non-host crops like corn, you disrupt the pest’s lifecycle, which decreases the amount of SCN in the field. Additionally, recent Iowa State University research supports adding a nematicide to your SCN management plans to further protect seeds from SCN. Syngenta recommends using Clariva Elite^® Beans seed treatment, an easy-to-handle premix of Clariva® pn nematicide and CruiserMaxx^® Vibrance^® seed treatment. Clariva Elite Beans is the only seed treatment on the market that provides season-long, lethal activity and broad-spectrum protection against SCN. By combining SCN-resistant varieties with traditional management practices, like crop rotation, and an effective seed treatment, like Clariva Elite Beans, you can protect your soybeans from SCN this season and into the future.

Systemic Fungicides Enhance Gummy Stem Blight Control

SyngentaAgronomy — Thu, 11 Jan 2018 20:27:50 +0000

Gummy stem blight control is known to cause yield loss of 30-40% if not properly managed. Researchers in key melon regions adjusted management recommendations for this disease during 2017 that growers can use to prepare for 2018. In a media release issued by Clemson announcing their release of the 2017 guide, researchers pointed out a major change to recommendations which now emphasize the importance of systemic fungicides to gummy stem blight management. Data discussed in the release demonstrated that the use of systemic fungicides reduced disease severity and also inhibited the formation of fungal spores to a greater extent than protectant fungicides. Per Clemson University Cooperative Extension Watermelon Spray Guide, Inspire Super® fungicide and Switch® fungicide are recommended for gummy stem blight management in a rotation program with fungicides from other FRAC groups. Inspire Super combines 2 active ingredients for broad-spectrum control of watermelon diseases via its translaminar and xylem-mobile systemic activity. Switch attacks disease pathogens at 4 different stages in the pathogen life cycle to provide long-lasting control.

Manage Resistant Weeds with these Key Strategies

SyngentaAgronomy — Wed, 17 Jan 2018 22:59:48 +0000

Caption: Marestail seeds As herbicide resistance becomes a greater issue in many key corn- and soybean-growing regions, it’s important to be thinking about the things you can do to face the problem head-on. University and industry research has cast doubt on common assumptions about managing resistant weeds and is rewriting some of the “rules” as a result. Use multiple, effective modes of action: Weed scientists conducted a study and found that consistent use of multiple, effective herbicide modes of action (MOAs) were effective in delaying the development of resistance. A field that received an average of 2.5 MOAs per application from 2004 to 2006 was 83 times less likely to produce glyphosate-resistant waterhemp seeds than a field that received 1.5 different MOAs per application. Don’t rely on herbicide rotation alone: Weed seeds carrying resistance can lie dormant, then germinate after 2 years and face the same herbicide that failed to control their parent weeds. If you’re using just one MOA in those years, it’s more likely that a resistant population will develop. A strong herbicide program should include pre-emergence and post-emergence herbicides, both with multiple effective MOAs. For control of resistant weeds in soybeans, we recommend starting with Boundary^® 6.5 EC (Groups 5 and 15), BroadAxe^® XC (Groups 14 and 15) or Prefix^® (Groups 14 and 15), followed by Flexstar^® GT 3.5 (Groups 9 and 14), each containing 2 MOA’s. When combined, a full pre- and post-emergence program using these products will contain 3 to 4 different effective modes of action. For control of resistant weeds in corn, we suggest using Acuron^® or Acuron Flexi corn herbicide. Acuron combines 4 active ingredients and has 3 effective MOAs (Groups 5, 15 and 27) while Acuron Flexi combines 3 active ingredients and has 2 effective MOAs (Groups 15 and 27). Both herbicides offer application flexibility, from 28 days pre-plant up to 12” corn for Acuron and 28 days pre-plant up to 30” corn for Acuron Flexi, and work well in 1 or 2-pass systems. A 2-pass system can also include a post-emergence application of Halex^® GT corn herbicide (Groups 9, 15 and 27) for an additional mode of action.

Preparing for Black Shank in Tobacco

SyngentaAgronomy — Thu, 18 Jan 2018 23:41:23 +0000

Tobacco stem cut, exposing blackened necrotic pith. Before black shank garners notoriety for damage to tobacco fields in 2018, growers should follow the advice shared by NC State Extension in 2017 and take preventive steps to lessen the severity of disease. Black shank is a soilborne fungal disease that can affect all stages of plant development. It infects plants through root tips and wounds, causing root and crown rots. Symptoms above ground include wilting, chlorosis and necrosis of leaves, necrotic girdling of the lower stem, and plant death. Disease symptoms are also expressed as necrotic girdling of the lower part of the stem. Because the pathogen that causes black shank overwinters in the soil and can survive for at least 4 years, it is important to factor field history into your management plan. Crop rotation, bedding fields and fumigation all contribute to a cleaner field. Orondis® Gold fungicide is another tool that can help you manage black shank. It combines the proven performance of mefenoxam with the latest active ingredient, oxathiapiprolin, for reliable protection and built-in resistance management. It also provides application flexibility, as it can be used at transplanting, at cultivation, or at lay-by.

The Dirt on Large-seeded Broadleaf Weeds

SyngentaAgronomy — Fri, 19 Jan 2018 21:14:06 +0000

Caption: Urbana, Ohio: Acuron applied pre-emergence at 2.5 qt/A with 1 qt/A atrazine in a field with a history of giant ragweed pressure. Application made on May 28, 2016. Photo taken 88 days after treatment. Cocklebur, giant ragweed and morningglory are often referred to as “large-seeded” broadleaf weeds because they produce larger seeds than their small-seeded counterparts: lambsquarters, marestail and waterhemp. While large-seeded broadleaf weeds tend to produce fewer seeds, the seeds are heartier and often remain viable in the soil for decades. Due to their larger size, the seeds often emerge from deep within the soil profile and present a larger plant mass when they appear, making them more established and difficult to control. To complicate matters, they often appear in flushes, which makes choosing a herbicide with strong residual control a must. The best approach to large-seeded broadleaf weed control in corn is to start clean with a burndown application or a burndown application followed by an application of Acuron® or Acuron Flexi corn herbicide. Both Acuron brands contain multiple, effective modes of actions including bicyclopyrone (group 27), which was developed to complement Callisto® herbicide (group 27) and provides improved control of large-seeded broadleaves. Since large-seeded broadleaves often come in flushes and residual is important to maintain season-long control, we recommend applying Acuron or Acuron Flexi in a 2-pass system: a foundation rate of Acuron or Acuron Flexi followed later by the remaining rate. This approach incorporates multiple, effective modes of action and helps ensure long-lasting residual control. Visit Acuron-Herbicide.com or talk to your local Syngenta retailer to learn more.

Include a Pre- and Post-Emergence Application in Your Herbicide Program

SyngentaAgronomy — Wed, 24 Jan 2018 19:34:51 +0000

Utilize pre- and post-emergence herbicide applications for the best control of resistant weeds like waterhemp. Because herbicide resistance is becoming so widespread, it’s important to apply both a pre-emergence and a post-emergence herbicide in order to protect your yield potential and prevent further development of resistance. In a weed management program, pre-emergence and post-emergence residual herbicides both serve important purposes and don’t usually provide sufficient control on their own. Pre-emergence herbicides are vital for effectively managing weeds that are beginning to germinate and keeping fields clean at planting time. Applying a pre-emergence residual will reduce the number of weeds in your field and provide long-term control. However, the University of Missouri says there will usually be some resistant weeds that escape the initial herbicide application. To avoid escape weeds, growers should follow their pre-emergence residual herbicide application with a post-emergence application. A post-emergence herbicide with a different mode of action (MOA) will help control weeds and prevent resistance. Purdue University says selecting effective residual herbicides and overlapping them is the best way to protect yield potential. Combining different MOAs in pre-emergence and post-emergence herbicides will overcome weeds that are resistant to multiple herbicides and create the best environment for your soybeans to grow. Syngenta offers a soybean herbicide portfolio filled with strong solutions to maximize herbicide diversity, fight resistance and increase yield. Boundary^® 6.5 EC and BroadAxe^® XC pre-emergence herbicides provide long-lasting, early-season residual control against weeds. Boundary or BroadAxe XC can be followed by Flexstar^® GT 3.5 post-emergence herbicide for overlapping protection against the most difficult weeds. Prefix^® herbicide is another convenient and effective pre-emergence option that can also be applied early post-emergence in a system preceding Boundary. By combining pre- and post-emergence herbicide applications, you can fight resistance and get the best protection against soybean weeds this spring and in the years to come.

Managing Tough-to-control Giant Ragweed

SyngentaAgronomy — Wed, 21 Feb 2018 20:59:02 +0000

Giant ragweed Giant ragweed is a large-seeded broadleaf weed that lives up to its name. It grows fast and can reach colossal heights of up to 20‘, pilfering water, nutrients and sunlight from surrounding corn and soybean plants as it grows. Its height and voracious appetite for resources aside, giant ragweed – like other large-seeded broadleaf weeds – is difficult to control because its seeds germinate deep within the soil profile where they are shielded from herbicide applications. While herbicide active ingredients are easily applied to weed seeds on or near the soil surface, they may not always reach deeper seeds or reach them at reduced rates. To complicate matters, the deeper germination depth means giant ragweed emerges with more plant mass, making it harder to control with post-emergence herbicide applications. Giant ragweed facts:

Can produce more than 5,000 seeds per plant
Is often 1 to 5 feet taller than the crop with which it is competing
Season-long competition from just 2 giant ragweed plants per 110 square feet can reduce corn yield by up to 13%

Learn how to identify and manage giant ragweed in this video with Joe Wuerffel, research and development scientist at Syngenta. Syngenta recommends controlling giant ragweed with Acuron^® or Acuron Flexi corn herbicides. Acuron has 4 active ingredients and 3 effective modes of action (Groups 5, 15 and 27), and Acuron Flexi has 3 active ingredients and 2 effective modes of action (Groups 15 and 27). Both herbicides contain the active ingredient bicyclopyrone (Group 27), which was developed to complement Callisto^® herbicide (Group 27) and provide improved control of large-seeded broadleaf weeds like giant ragweed. For soybeans, a pre-emergence herbicide applied prior to the weed reaching 4’’ in height is recommended. A post-emergence herbicide, such as Flexstar^® GT 3.5 that delivers 2 different modes of action (Groups 9 and 14), can help control glyphosate- and ALS-resistant giant ragweed. Backed by decades of research and development, Syngenta has been at the forefront of introducing herbicides with multiple effective modes of action to help fight resistance. The Syngenta Resistance Fighter^® program provides education, local recommendations, and a comprehensive herbicide portfolio to help growers and retailers effectively manage resistant weeds in their area.

Identify and Manage Kochia

SyngentaAgronomy — Tue, 27 Feb 2018 18:32:18 +0000

Kochia A number of key characteristics of kochia can make it especially difficult to control. The United Soybean Board reports kochia is tolerant to hot, dry conditions and soils with high salinity. It can produce up to 30,000 seeds per plant, its roots can extend down 15’ and measure 21’ in diameter and the weed itself can grow up to 6’ high. In addition, herbicide-resistant kochia rapidly evolves due to short seed life, high genetic diversity and heavy reliance on herbicides for control in minimum- and no-till cropping systems. Kochia facts:

It is an early-germinating summer-annual broadleaf weed species
It can be found in crop fields throughout the Midwest
It is capable of self- or cross-pollination, making it likely that glyphosate resistance could spread via gene flow
After the plant has matured, kochia will break off at the ground and roll in the wind or in the direction of a slope
As it rolls, seed is deposited in new areas, spreading the genetics from a single plant over great distances

Learn how to identify and manage kochia in this educational video with Joe Wuerffel, Ph.D., research and development scientist at Syngenta. Manage and prevent kochia throughout the growing season with an application of Acuron^® or Acuron Flexi corn herbicides. Acuron has 3 effective modes of action (Groups 5, 15 and 27) and Acuron Flexi has 2 (Groups 15 and 27). Both herbicides contain bicyclopyrone, which is designed to complement the other active ingredients in the premix to deliver broader spectrum, more consistent control of tough weeds other products are missing For soybean growers, Syngenta offers effective weed control programs that can start with BroadAxe^® XC herbicide (Groups 14 and 15) for pre-emergence, long-lasting residual control of kochia. Syngenta recommends an application of Talinor^™ herbicide for cereals, as it combines 2 active ingredients with 2 different modes of action for effective weed control (Group 27 and 6).

Tips For Managing Waterhemp

SyngentaAgronomy — Fri, 16 Feb 2018 22:28:43 +0000

Waterhemp Waterhemp is a small-seeded broadleaf weed and one of the most common weeds found in corn and soybean fields. Like other small-seeded weeds (marestail, Palmer amaranth), waterhemp is a prolific seed producer. Its small, lightweight seeds tend to thrive in minimum and no-till situations where they can easily germinate near the soil surface or in crop residue. Unlike large-seeded broadleaf weeds, waterhemp emerges with less plant mass and its close proximity to the soil surface makes it more susceptible to herbicide applications. The sheer number of seeds it produces however, makes it difficult to control. Waterhemp plants that are left to go to seed can quickly populate the soil seedbank with millions of seedlings, spreading resistance and ensuring it remains a costly problem for years to come. Waterhemp facts:

- Produces up to 1 million seeds per plant
- Can grow as much as 1” per day and up to 4 to 5’ in height, with some weeds reaching up to 12’
- Pollen can travel a half-mile or more, cross-pollinating other waterhemp plants and spreading resistance
- Early-season competition can reduce corn yield up to 15% by the time weeds are just 6” tall

Learn how to identify and manage waterhemp in this video with Joe Wuerffel, research and development scientist at Syngenta. Growers can control waterhemp and protect corn yields by employing multiple, effective modes of action that provide residual control and a start-clean, stay-clean approach to weed control. Acuron^® corn herbicide has 4 active ingredients and 3 effective modes of action (Groups 5, 15, and 27). Its atrazine-free counterpart, Acuron Flexi corn herbicide, has 3 active ingredients and 2 effective modes of action (Groups 15 and 27). Both contain the active ingredient bicyclopyrone, which complements the other active ingredients to deliver more effective and more consistent waterhemp control than competitive products. For optimal control, these brands should be applied before waterhemp emerges. Acuron and Acuron Flexi can be applied alone or pre-emergence followed by a post-emergence application of Halex^® GT corn herbicide (Groups 9, 15 and 27) plus AAtrex^® corn herbicide (Group 5). Syngenta also offers an effective soybean weed control program that starts with pre-emergence, long-last residual control from Boundary^® 6.5 EC herbicide (Groups 5 and 15) or BroadAxe^® XC (Groups 14 and 15). In addition, a post-emergence application of Flexstar^® GT 3.5 delivers 2 different modes of action (Groups 9 and 14) to control glyphosate- and ALS-resistant waterhemp.

Flexibility Matters When Working With Mother Nature

SyngentaAgronomy — Fri, 26 Jan 2018 17:15:52 +0000

Mother Nature is a tough business partner; she’s not forgiving, not flexible, and doesn’t always work with the wellbeing of the farm in mind. Variable weather conditions during planting can easily shrink the corn herbicide application window, making it tough to achieve timely herbicide applications and start with clean, weed-free fields. Corn herbicides with flexible application windows help alleviate the stress of variable conditions and make it easier to make timely applications. Acuron® corn herbicide can be applied 28 days pre-plant up to 12” corn, and Acuron Flexi can be applied just as early and up to 30” corn. Both herbicides combine multiple, effective modes of action and a corn safener to provide safe, consistent control of tough broadleaf weeds and annual grasses, even resistant biotypes.

Control Diamondback Moth Population to Protect Brassica Crops

SyngentaAgronomy — Mon, 29 Jan 2018 16:42:21 +0000

Diamondback moth caterpillar When left unchecked, diamondback moth infestations can cause severe stunting in brassica crops. Per the University of California extension, diamondback moths can damage the crowns or growing points of young plants, stunting growth and resulting in financial loss for growers. Diamondback moth populations tend to increase in the spring and early summer, so now is the time to consider management options. Insecticides are an effective way to manage diamondback moths. During the seedling stage, start checking crops for larvae, checking again at the thinning and heading stages. If larvae or moths are spotted, be sure to check adjacent border rows as infestations can spread from field to field via the adult moths. Once infestation is confirmed, apply insecticide as directed. To protect brassica crops, Syngenta recommends Besiege® insecticide, a broad-spectrum foliar insecticide providing fast knockdown and long-lasting residual control of diamondback moth, cabbage looper, and other key pests.

What to Expect from Resistant Weeds in 2018

SyngentaAgronomy — Fri, 02 Feb 2018 19:03:47 +0000

Young waterhemp that survived an ineffective herbicide application. Weed management is always a major concern for growers throughout the U.S., and last year’s weed escapes will have left seeds in the soil for growers to contend with this season. This problem, combined with the growing issue of herbicide-resistant weeds, makes weed management a big concern in 2018. Growers can expect resistant weeds to continue to spread across key corn and soybean growing regions in 2018. A recent Iowa State University report said Palmer amaranth was identified in many new counties in Iowa, and will likely be found in every Iowa county this year. Michigan State University reported that resistant weeds, like marestail, spread to new counties last season, and glyphosate-resistant giant ragweed was also discovered for the first time in the state. This year, it’s not enough to rely on 1 herbicide and trust it to knock out every weed in the field. In order to protect yields in 2018 and in the future, growers need to diversify their weed management programs by implementing traditional cultural practices, like tillage and the use of cover crops, in addition to applying herbicides with multiple effective modes of action. This combination of strategies can significantly extend the life of herbicides treatments and delay the spread of resistance for years to come. Growers are encouraged to visit www.ResistanceFighter.com or talk to their local Syngenta sales representative to learn more about receiving a customized herbicide program to efficiently control the weeds in their fields.

Fight Weeds with a Faster Speed-to-Canopy

SyngentaAgronomy — Fri, 09 Feb 2018 00:51:25 +0000

Young soybean plants. With weeds being such a large threat to soybeans, it’s important to start managing them before they begin to grow. Weeds usually germinate with the soybean plant, which makes it difficult for the soybean plant to outgrow the weed. When weeds are present, they compete with your soybean plants for nutrients, which can ultimately lead to decreased yields. In addition to using an effective herbicide program, planting treated seed can help promote a faster speed-to-canopy from the start. This will give your soybeans a fighting chance to absorb the necessary nutrients for growth before weeds have the opportunity to takeover. CruiserMaxx^® Vibrance^® Beans seed treatment, a combination of separately registered products, contains 4 proven active ingredients. These active ingredients are engineered to help your soybeans establish a strong defense system from root to leaf in their critical early-growth stages. CruiserMaxx Vibrance Beans is boosted with the Cruiser^®Vigor Effect and the unique RootingPower of Vibrance fungicide to help increase soybean plant speed-to-canopy. Check out the video below to see the RootingPower of Vibrance on soybeans and to understand why a faster speed-to-canopy is crucial when managing weeds.

Watch for Southern Rust in 2018

SyngentaAgronomy — Sat, 17 Feb 2018 00:42:28 +0000

Southern rust on untreated corn. When preparing your management strategy for the 2018 growing season, it’s important to remember what diseases were seen in 2017. One disease that is progressing more and has started to affect a larger number of fields throughout the South and Midwest is Southern rust. Southern rust can be expected in corn fields throughout the South, but it’s been spotted in the Midwest with increasing frequency. Although rust diseases rarely cause major yield loss in the Midwest, Purdue University emphasizes that Southern rust has the greatest potential to damage yields if it reaches the Midwest at a critical point in the growing season. Southern rust does not survive Midwest winters, but it is carried in on wind currents each year. It develops in warmer weather and has been appearing in the Midwest in late August or September. This disease has been known to reduce yields as much as 25 bu/A when a fungicide has not been applied. Syngenta offers Trivapro^® fungicide for best-in-class preventive and curative control of rust as well as leaf spots and blights. Trivapro also delivers plant health benefits that help maximize grain-fill and protect stalk strength for reduced lodging.

Controlling Resistant Weeds is Easier Than You Think

SyngentaAgronomy — Thu, 22 Feb 2018 19:02:31 +0000

Clean soybean rows Resistant weeds are spreading, and many weed species are developing multiple forms of resistance against current herbicide modes of action (MOAs). In a 2017 study, researchers at the University of Wisconsin Extension found that from 2013 to 2016, waterhemp and Palmer amaranth with multiple forms of resistance spread throughout the state. The University of Nebraska-Lincoln found that 4 weed species in that state have evolved resistance to multiple herbicides as of 2017. As the number of effective herbicides available drops, managing resistant weeds rises as a major concern for growers. To see how growers feel about their ability to control resistant weeds, we conducted a Twitter poll and asked our followers how much control they feel they have handling weed resistance on their farms. While 48% of respondents said they felt in control of the weeds in their fields, 32% felt like they were only somewhat in control and 9% felt like they were not in control at all. The key to managing resistant weeds lies in using a diverse array of weed control methods. Multiple effective herbicide MOAs are necessary to control weeds with multiple resistance in order to attack them in different ways. It’s also been shown you can’t rely solely on herbicide rotation. Instead, combine traditional management practices, such as tillage or crop rotation, with a diverse chemical weed management program. While most fields have at least a few resistant weeds in them, growers can prevent the spread of weed resistance by using responsible management practices. For the 41% of growers who feel they are only somewhat or not in control of resistant weeds, don’t panic. A significant resistance issue will not spiral out of control quickly, so long as growers stay proactive.

Hybrid Rice: Over-treatment for Better Stands and Higher Yields

SyngentaAgronomy — Fri, 23 Feb 2018 22:54:22 +0000

Rice growers can utilize neonic seed treatments to protect against harmful pests and diseases. An AR extension trial showed that plots that applied neonic seed treatments early had fewer issues with bugs and disease compared to plots without seed treatment. Neglecting to incorporate a seed treatment into rice plots can result in severe stand injury and yield loss. Over-treating hybrid rice with a seed treatment can help prevent these issues and maximize stand count. Adding to the base treatment can also improve uniformity and vigor. Higher yields are possible with added protection from over-treating hybrid rice. Syngenta recommends over-treating with CruiserMaxx® Rice insecticide/fungicide seed treatment to a typical base treatment. It’s proven to help increase plant stands, uniformity and vigor, and improve quality and yield potential.

Managing Palmer Amaranth to Delay Resistance

SyngentaAgronomy — Thu, 08 Mar 2018 00:09:44 +0000

Young Palmer amaranth Palmer amaranth’s reputation as a difficult-to-control weed often precedes its arrival. After working its way through the South, Palmer amaranth is now moving into the Midwest. According to Joe Wuerffel, research and development scientist at Syngenta, Palmer amaranth has now been reported as far north as Minnesota. A small-seeded broadleaf weed, Palmer amaranth produces thousands of seeds that are well adapted to today’s minimum and no-till practices. Seeds typically germinate close to the soil surface and emerge well into the season, sometimes even after harvest has concluded. Worse still, many populations have developed resistance to glyphosate, ALS and HPPD inhibitors, with some exhibiting resistance to multiple modes of action. Because Palmer amaranth can cross-pollinate with other weeds in the amaranthus family, resistant populations can spread rapidly, overtaking entire geographic areas. Palmer amaranth facts:

- Produces up to 100,000 seeds per plant and germinates throughout the season
- Thrives in reduced-, minimum- and no-till systems because it germinates close to the soil surface
- Aggressively competes with corn and soybeans, growing up to 3” per day and reaching up to 8’ in height
- When allowed to compete throughout the growing season, it can create yield losses up to 91% in corn and 79% in soybeans

Learn more about how to identify and manage Palmer amaranth. Despite it’s tough reputation, Palmer amaranth is manageable with a start clean, stay clean approach to weed control that incorporates multiple, effective modes of action. Syngenta recommends Acuron^® corn herbicide, which has 3 effective modes of action (Groups 5, 15 and 27) and Acuron^® Flexi corn herbicide, which has 2 (Groups 15 and 27). For optimal control of Palmer amaranth, these brands should be applied before it emerges. Acuron and Acuron Flexi can be applied alone or pre-emergence followed by a post-emergence application of Halex^® GT corn herbicide (Groups 9, 15 and 27) plus AAtrex^® corn herbicide (Group 5). Syngenta also offers an effective weed control program in soybeans that starts with BroadAxe^® XC herbicide (Groups 14 and 15) or Boundary^® 6.5 EC (Groups 5 and 15) herbicide for pre-emergence weed control of Palmer amaranth with long-lasting residual and multiple modes of action. A post-emergence application of Flexstar^® GT 3.5 (Groups 9 and 14) delivers 2 different modes of action to control glyphosate and ALS resistance.

Root and Stolon Protection with In-furrow Application

SyngentaAgronomy — Mon, 05 Mar 2018 17:00:31 +0000

Fungicides applied directly to the seed protect against seed-borne disease, but are limited in their ability to protect the plant from soil-borne pathogens. In the absence of an in-furrow fungicide, the plant may encounter soil-borne pathogens as the root and stolon structures expand beyond the area protected by the seed treatment. Rhizoctonia solani attacks tubers, underground stems and stolons of plants, causing diseases such as black scurf and stem canker. The pathogen is typically introduced into fields on potato seed tubers or through contaminated soil. Sclerotia in soil or on seed tubers germinate, and the resulting mycelium colonizes plant surfaces where nutrients are available. Cold and wet soils also favor disease development. The most damaging phase of the disease occurs underground and often goes unnoticed. Severe lesions are large and sunken. If the fungal lesion expands quickly, relative to the growth of the plant, the stolon or stem can be girdled and killed. Soil applied fungicides, such as Elatus® fungicide, can help protect potatoes from diseases such as black scurf and stem canker. Elatus applied in furrow can help prevent stand loss, post-emergence sprout death, disproportionate tuber sizing, early loss of stolons and girdling.

Protect Your Pome Fruit Throughout Bloom Phase

SyngentaAgronomy — Thu, 01 Mar 2018 01:45:14 +0000

Pear psylla With spring around the corner, now is the time to initiate your pome insect and disease management program to ensure maximum growth and fruit quality. Below you’ll find several key pests and diseases common to the Pacific Northwest along with management tips and considerations. Key Pests Pear psylla is a notorious pest, damaging pear trees in many ways. Nymphs and adults produce honeydew that drips onto fruit which promotes sooty mold and can lead to russeting. Severe infestations can lead to defoliation and fruit drop. To control these populations, apply Minecto® Pro insecticide, which offers broad-spectrum control of common pome fruit pests, from petal fall through first cover. Codling moth is a troublesome pest for pome fruit, particularly apples. Larvae feed on the fruit causing blemishes that leave the fruit unmarketable. If larvae penetrate far enough into the fruit, rotting can also occur. Overwintering populations typically emerge shortly after petal fall, making this a prime time to apply Minecto Pro. This treatment harnesses the power of 2 complementary active ingredients, cyantraniliprole and abamectin, to control overlapping pest populations. Common Diseases Powdery mildew is a fungal disease attacking both apples and pears. Infected leaves appear to have a white or gray powder on them and will curl upward as they become covered in spores. Powdery mildew will damage tree vigor, fruit quality and yield. You will likely see the best treatment results with a fungicide application like Aprovia® fungicide between the pink and petal fall stages and through your cover sprays. Fire blight is a bacterial disease infecting both apples and pears that has been a big issue for growers in the Pacific Northwest beginning at bloom. Fire blight overwinters as cankers on trees in infected orchards and secrete bacterial residue that can be spread throughout the area. As the growing season progresses, open flowers, twigs and leaves will blacken and appear scorched. When conditions favor fire blight infection, implement a management program that includes Actigard® plant activator and traditional antibiotics. Actigard triggers the tree’s natural defense system, much like a vaccine. Insecticide and fungicide applications – in combination with other management practices – can help improve orchard health year after year. Institute your management plans now to minimize insect and disease problems this growing season and protect fruit quality and yield.

Develop an SCN Management Plan for 2018

SyngentaAgronomy — Thu, 01 Mar 2018 01:55:56 +0000

Protect SCN-resistant varieties with nematicide seed treatments and crop rotation to control SCN and maximize yield. Soybean cyst nematode (SCN) is the most damaging pest to soybeans in the U.S. The University of Minnesota Extension says the pest causes an estimated $1 billion loss annually. Although there is no way to eradicate SCN once it’s present in a field, there are several management practices you can use to reduce SCN population density and increase yield potential. When developing an SCN management plan for 2018, be sure to include these key strategies: 1. Plant soybeans with the best possible genetics for resistance. Resistant varieties can be effective on some populations of the pest, though the genetic diversity of SCN has started to overcome the most popular genetic source of resistance – PI88788. 2. Use an effective seed treatment. Backed by Iowa State University researchers, since almost every variety of SCN-resistant soybean seeds rely on the same gene, it is important to also use a nematicide seed treatment to manage SCN and protect SCN-resistant seed genetics. Some seed treatments also provide early-season protection against insect feeding, which provides an entry point for disease infection and nematode damage. 3. Practice crop rotation. While SCN can survive several years in soil, it cannot reproduce in non-host crops like corn, alfalfa or wheat, and population densities decline every season the nematodes are denied a host. The combination of these practices is the best approach to thwarting SCN and taking soybean yield potential to the highest level. For an effective seed treatment, Syngenta recommends using Clariva® Elite Beans, a premix formulation of Clariva pn nematicide and CruiserMaxx® Vibrance® seed treatment. Clariva Elite Beans is the only seed treatment on the market that provides season-long, lethal activity and broad-spectrum protection against SCN, as well as early-season insects and diseases.

Manage Heightened Almond Stress Caused by Recent Weather Events

SyngentaAgronomy — Thu, 01 Mar 2018 17:08:20 +0000

Parts of California have experienced higher-than-average temperatures and lower-than-average precipitation over the past year. Then there was the recent freeze and now a forecast for strong storms to sweep across the state. All of this weather variability means almond orchards are facing severe stress during the critical bloom phase. During these times of extreme weather changes, it may be tempting to make 2 incorrect assumptions:

Almond trees are drought tolerant, so they are better able to withstand periods of stress.
Precipitation levels are currently down, so the risk of bloom disease is likely low.

Both assumptions can be costly for trees that face unexpected stress and disease outbreaks. Here are 4 tips to optimize tree health through almond bloom.

Monitor orchard stress. While almond trees are drought tolerant, a lack of water can have a high impact on yield potential. Water stress reduces a tree’s ability to produce carbohydrates, which is a critical nutrient for proper almond development. Water-deficient trees may experience early-season leaf drop and, in extreme cases, total tree defoliation. Growers can use a portable pressure chamber to measure "midday stem water potential" for signs of stress. Minimizing stress increases photosynthesis and growth potential.
Manage water usage. Water demand is lower during bloom compared to demand in the heat of summer. However, extreme heat and dry spells may tempt you to over-irrigate, which creates the perfect conditions for diseases to thrive. Limiting irrigation to 24 hours and draining any standing water from the crown will help minimize disease risk.
Identify disease warning signs. While moisture levels have been low, freeze protection led many growers to run irrigation. That standing water combined with the forecast for heavy storms creates a ripe environment for disease. Two key diseases that may be problematic this year are anthracnose and root rot, and affected orchards can lose vigor quickly. Oftentimes, trees are already in a declining state when disease is identified. Here are some early warning signs to aid in proactive management:
- Anthracnose – Look for yellow lesions that begin at the leaf margin or tip and advance toward the middle of the leaf. The disease overwinters in dead wood or mummified fruit that remain attached to the tree, so infection can occur from the previous year.
- Root rot – Keep an eye out for leaves that wilt, dry and remain attached to the tree. Chronic infections, usually of the roots, cause reduction in growth and early senescence and leaf fall. Younger trees are particularly threatened because their root structures are smaller than mature trees.
Prepare with a fungicide application. A fungicide application at bloom can help mitigate environmental stress and help boost trees’ natural defenses.
- Quadris Top® fungicide can provide more complete protection from anthracnose early in the season when the tree is most vulnerable.
- Ridomil Gold® SL fungicide can protect against root rot and increase feeder root growth to ensure better water and nutrient use efficiency.

A fungicide application – among other management practices – provides multiple physiological benefits to help improve the overall health of your orchards year after year.

Proven Branded Seed Treatment vs. Generic Custom Blend

SyngentaAgronomy — Fri, 02 Mar 2018 12:33:26 +0000

CruiserMaxx^® Vibrance^® Beans Generic custom blend Generic custom blend Consistent formulation of CruiserMaxx Vibrance Beans makes for a more even distribution on the seed. With planting already underway in the deep South or quickly approaching, it’s time to start finalizing input decisions that will affect the results of your growing season. Although generic custom blend seed treatments are typically less expensive than branded seed treatments, it’s important to know why.

Inconsistent formulation: Generic seed treatments don’t always have a consistent formulation, which can cause ingredient separation rather than a fluid mixture. This can lead to a disproportional distribution of active ingredients, and therefore unreliable performance.
Equipment clogging: Generic seed treatments have a higher likelihood of clogging both treating and planting equipment due to their inconsistent formulation and distribution on the seed.
Dust-off: Generic seed treatments are more likely to have trouble sticking to seeds, coming off in equipment or being lost when the seed is transferred between the planter and the ground. This can leave seeds more vulnerable to insects and diseases during a crucial stage in development.

Additionally, Ohio State University says seeds planted into cool or warm, wet soils are particularly vulnerable to infection from a number of different pathogens. CruiserMaxx^® Vibrance^® Beans, a combination of separately registered products, is a proven seed treatment with a consistent formulation, delivering an even distribution of active ingredients on each seed. It reduces the dust-off and equipment clogging issues that you might experience with a generic custom blend seed treatment. It also helps soybeans emerge quicker and more evenly, with increased root and shoot vigor. Not only does this help soybeans start strong, but it will also increase speed-to-canopy, which will help reduce competition against early-season weeds.

Protect Your Potato Yields From Start to Finish

SyngentaAgronomy — Fri, 02 Mar 2018 20:38:08 +0000

Where you start can make a big difference in how you finish. One such example is growing potatoes. Setting a strong foundation at the beginning of the season is a key element in finishing strong with high quality yields. Rhizoctonia solani is a pathogen that is often present in soil or on seed tubers and can have a major impact on young plants. It causes diseases such as black scurf and stem canker. Wet and cold soils favor disease development, and infection can result in major damage underground. If fungal lesions expand too quickly in relation to plant growth, stolons and stems may be girdled and die. CruiserMaxx® Vibrance® Potato insecticide/fungicide seed treatment helps growers start strong with insect and disease protection. It provides 3 industry-leading fungicides for Rhizoctonia, Helminthosporium and Fusarium protection plus an insecticide component to protect against key pests through the Cruiser Vigor Effect. CruiserMaxx Vibrance Potato helps enhance germination, increase vigor and improve stand establishment, while improving size and tuber distribution to maximize quality yields.

Planting Season 2018: Do Your Cleaning Before the Spring

SyngentaAgronomy — Sat, 03 Mar 2018 00:14:15 +0000

As you get ready for the upcoming planting season, it’s important to make sure your equipment is in proper working order. Taking the time to clean your planters from last year can make for an easier planting process, and ultimately increase yield as more seed makes it into the ground. Here are a few tips for cleaning, which require only a shop vacuum and a few common tools:

Seed boxes:
- Clean out old seed, which can gather at the bottom of boxes and clog seed outlets.
- Make sure no old seed sprouted since the seeder’s last use.
- Clear out any spider webs.
Seed transport mechanism:
- Clean out the transport mechanism and its narrow outlets.
- Remove all tubes and clean them. Clogged tubes cannot transport seed and will impact your stand density.
Planter wheels:
- Clean wheels.
- Check wheel bearings to make sure they work without wobbling.

With coated seeds being increasingly common, now more than ever it’s important to clean your equipment after each use. High humidity can cause the clay-based coating on seeds to cement together, making them difficult to remove. This isn’t to discourage growers from using treated seeds, however. Studies have shown using seed treatments such as Clariva^® Elite Beans and CruiserMaxx^® Vibrance^® Beans, a combination of separately registered products, allow you to plant earlier in the season, potentially increasing your yield and profit per acre. For cereals, CruiserMaxx Vibrance Cereals insecticide/fungicide seed treatment provides superior disease protection, increased emergence and enhanced plant vigor, even in cool conditions. More vigorous root systems improve plant stand, which is the starting point for maximum yield potential. Read more on the importance of using a seed treatment during the 2018 planting season.

2018 Stripe Rust Predictions

SyngentaAgronomy — Wed, 07 Mar 2018 00:55:45 +0000

Although stripe rust was present across the U.S. last year, USDA-ARS Research Plant Pathologists observed fields in late fall 2017 and has predicted that stripe rust will not be a major factor for growers this season. This may be due to a combination of resistant varieties, timely fungicide application and less favorable winter conditions. While stripe rust is not expected to be a huge threat in the 2018 season, you should still be prepared to fight it, should it appear. The University of Georgia Extension reports that the first sign of stripe rust is yellow streaks, followed by the appearance of small, elongated, bright yellow pustules arranged in rows on the leaves. Mature pustules will break open and release orange-yellow masses. The leaves may become brown and dry as the plant continues to grow or becomes stressed. If you find rust in your wheat, we recommend applying Trivapro^® fungicide, which provides long-lasting control of stripe rust and leaf rust. One application of Trivapro delivers stronger residual control compared to competitive 1-pass and 2-pass programs. It’s important to frequently check fields early in the season. Plants have a better chance at fighting stripe rust when it’s caught early and fungicides are applied at the appropriate time.

Resistant Lettuce Varieties Help Protect Against Downy Mildew

SyngentaAgronomy — Fri, 09 Mar 2018 23:18:50 +0000

Downy mildew poses a serious threat to growers across all lettuce producing regions. However, growers can take steps to protect their crops from disease pressure by understanding the threat and selecting the best trait package when choosing lettuce varieties. Combined with a comprehensive crop protection program, resistant varieties can help growers avoid key lettuce diseases such as downy mildew Downy mildew epidemics develop in dry conditions followed by humidity, and can destroy lettuce crops. As spores land on wet leaves, infection can occur in as little as 3 hours. Growers should take into account that the pathogen that causes downy mildew is highly adaptable and strains present in fields can vary year to year. Choosing resistant varieties, implementing a fungicide program and closely monitoring weather conditions can help growers minimize the impact of downy mildew on their crops. Syngenta approaches this problem with a dedicated lettuce breeding program and collaboration with other breeders around the world to develop the best traits and resistances. Several Syngenta romaine, iceberg and butterhead varieties, such as Abilene, Rio Bravo and Lucan, feature resistance to downy mildew and other key lettuce diseases. Along with disease resistances, lettuce varieties are bred for characteristics and traits such as color, head size, and weight to ensure that growers can maximize yield in any conditions.

Plan Ahead for Early-Season Soybean Insects

SyngentaAgronomy — Mon, 12 Mar 2018 22:26:02 +0000

Adult bean leaf beetle Soybean planting is around the corner, so now is the time to brush up on what early-season insects to scout for. Left unrestricted, these pests damage yields at the critical growth stage. One early-season pest to watch for is the bean leaf beetle, which can overwinter and become active as early as April. Bean leaf beetles move quickly through fields, so early-planted fields usually suffer the most damage. The best way to combat a bean leaf beetle infestation is to prepare early. Bean leaf beetles can vary in color, but are usually red or yellow-tan. Most have a set of distinctive black spots with a black border around the outside of their wings. Another soybean pest to watch for early in the season is the soybean aphid. These pests can start to show up at soybean emergence and persist through the leaf drop phase. Fields with wooded borders and early-planted fields both have a higher risk of aphid infestation early in the season. Additionally, the presence of lady beetles or ants early in the season is often a key indicator of an aphid infestation. Soybean aphids are small, soft-bodied insects that are yellow-green in color. Their bodies are pear-shaped and have a pair of dark cornicles. With both of these early-season insects having the potential to significantly impact yields, it’s important to have a management plan prepared before the season kicks off. For protection against these damaging early-season insects and diseases, we recommend using CruiserMaxx^®Vibrance^®Beans seed treatment, a combination of separately registered products. CruiserMaxx Vibrance Beans is the only seed treatment that offers the unique RootingPower of Vibrance fungicide and the Cruiser^® Vigor Effect, which reduces the risk of soybean stand establishment problems. This treatment can also help protect growers’ seed investment and avoid the need for costly replanting.

Tips to Maximize Your Corn and Soybean Yields

SyngentaAgronomy — Wed, 14 Mar 2018 23:11:25 +0000

The 2018 season could be another rough year for growers. Current fall delivery bids are around $3.60 per bushel for corn and around $9.60 for soybean. These low prices are similar to situations in 2016 and 2017, which means you’ll need to maximize your yields this year so you can break even. However, there are a number of things you can do to achieve above-trend yields in both corn and soybeans, starting with an effective weed management strategy. In combination with recommended cultural practices, choosing a proven herbicide program is crucial to winning the battle against yield-robbing weeds. It’s important to choose a program with overlapping residual herbicides containing multiple effective sites of action (SOAs) in both the pre- and post-emergence applications. For control of tough weeds in corn, we recommend using Acuron ^® or Acuron Flexi corn herbicide. Acuron is a combination of 4 active ingredients with 3 effective SOAs, while Acuron Flexi is a combination of 3 active ingredients with 2 effective SOAs. Both products provide application flexibility, with the ability to spray from 28 days preplant to 12” corn for Acuron, and 28 days preplant up to 30” corn for Acuron Flexi. A two-pass system can also include a post-emergence application of Halex^® GT corn herbicide for an additional site of action. For broad-spectrum control of weeds in soybeans, we recommend making a pre-emergence application of Boundary^® 6.5 EC, BroadAxe^® XC or Prefix^® herbicides, each containing 2 SOAs. Additionally, you can follow up Boundary 6.5 EC and BroadAxe XC with a post-emergence application of Flexstar^® GT 3.5, which also includes 2 SOAs to combat weeds that are difficult to control with glyphosate alone or those that are resistant to ALS-inhibitors. Not only will these products help you achieve above-trend yields, but using them correctly will also help prevent the development and spread of resistance.

Vertical Tillage: A Valuable Tool for Managing Weeds

SyngentaAgronomy — Fri, 16 Mar 2018 22:08:26 +0000

Burndown followed by vertical tillage Vertical tillage followed by burndown Weed pressure 18 days after treatment (Pana, IL) As difficult-to-control weeds continue to emerge year after year, you’re probably starting to think about all of the elements of a successful weed management program. It’s important to choose a herbicide program with pre- and post-emergence applications, both containing multiple effective sites of action (SOAs). Beyond chemical weed management, there’s even more you can do to give your crops a fighting chance against weeds this season. Utilizing a burndown application followed by vertical tillage can aid in reducing weed presence. Starting with a burndown application will kill some of the weeds in your field. It also provides the opportunity to add another site of action against weeds. Following your spring burndown application with vertical tillage can finish off any remaining weeds that might have survived the herbicide application. Additionally, researchers found using a vertical tillage tool improved planting by creating a uniform warm and dry seedbed across the field. Following these steps will help provide the best chance against fighting weeds this season:

Start clean with a spring burndown application. Syngenta recommends applying Gramoxone^® SL 2.0 herbicide for outstanding burndown control of annual grass and broadleaf weeds.
Practice vertical tillage to manage lingering residues.
Apply a pre-emergence herbicide containing multiple effective SOAs. Syngenta recommends using BroadAxe^® XC or Boundary^® 6.5 EC herbicides for long-lasting early-season weed management.
Follow up with a post-emergence herbicide containing multiple effective SOAs before weeds reach 4” tall. Syngenta recommends using Flexstar^® GT 3.5 for proven post-emergence protection.

Get An Early Handle On Almond Diseases

SyngentaAgronomy — Thu, 22 Mar 2018 15:31:08 +0000

Rust on an almond leaf As temperatures heat up, so does disease pressure in almond orchards. Rust, scab, Alternaria leaf spot, anthracnose and shot hole are prevalent in the spring and summer, potentially damaging leaves, nuts and overall tree health if not properly identified and controlled. To help ensure the long-term health of your orchard, scout early and often and apply fungicides when needed. Here are a few symptoms to look out for:

Scab: Scab affects both leaves and fruit, causing indistinct, green-yellow lesions on leaves and small green to olive-colored circular spots on the upper surface of fruit. These spots often grow and darken as the disease develops. Severe infection can lead to preharvest defoliation, weakened trees and compromised long-term health.
Shot hole, rust and Alternaria leaf spot: These common leaf diseases are characterized by holes in the leaves, yellow discoloration on the upper surface of leaves, and large brown or black spots on leaves, respectively. Improper or untimely management of these diseases can result in yield loss, defoliation and weakened trees.
Anthracnose: Anthracnose causes round, orange-colored lesions on nut hulls. Untreated hulls become mummies and create a feeding and breeding ground for navel orangeworm.

The likelihood of disease increases in periods of extended moisture and humidity. Quadris Top® fungicide offers broad-spectrum control of these and other diseases, and has been shown to provide effective control in the May spray timing.

Monitor For Active Insects in Almond Orchards

SyngentaAgronomy — Thu, 22 Mar 2018 16:22:05 +0000

Peach twig borer Detrimental to new growth, spider mites and peach twig borer are active in almond orchards during fruit development. Peach twig borers burrow into growing shoots where they feed from the inside out, while spider mites are found on the leaves in the lower to central areas of the tree early in the season and spread as temperatures get warmer. Spider mite Scouting is the key to early detection and timely management. Spider mites feed on leaves, causing leaf stippling and yellowing, and can ultimately lead to defoliation. High populations are characterized by a webbing that forms over tree terminals. If left uncontrolled, mites can reduce vegetative growth the following year and compromise yield. Experts recommend scouting for peach twig borer (PTB) beginning in mid-April. A tell-tale sign is often called “flagging” or “shoot strike.” This occurs when PTB burrows into shoots and twigs, causing them to wilt. This can also be a symptom of oriental fruit moth (OFM) damage; however, OFM damage typically occurs later in the season. PTB can also attack and feed on nuts later in the season. However, this damage is often masked by navel orangeworm (NOW) damage. Including Minecto Pro® insecticide in your May spray program helps control spider mites and PTB. With 2 complementary active ingredients, cyantraniliprole and abamectin, Minecto Pro controls multiple pest populations that overlap or occur at the same time.

Herbicide Flexibility Simplifies Weed Management

SyngentaAgronomy — Fri, 23 Mar 2018 15:57:35 +0000

Every year, wheat growers turn to herbicides to combat tough broadleaf weeds like kochia and Russian thistle. The success of your herbicide depends on a well-executed application, which can often be sabotaged by Mother Nature’s volatility. Growers can offset weather hurdles and improve their weed control by choosing a herbicide with application flexibility. Here are some factors to consider:

Application window: A flexible application window helps mitigate the challenges of working in sporadic weather conditions, making the timing of applications easier.
Application rate: A range of application rates lets you tailor your application to your level of weed pressure.
Tank mixing: Tank-mix flexibility can increase efficiency by giving you 1-pass grass and broadleaf control.
Rotational crops: Compatibility with a wide range of rotational crops allows you to better customize your fields.
