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!
