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

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.

Edited

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.
