Key Issues Perspective: Rotate Herbicides in Corn on Corn
Growers should rotate different herbicide traits and not be afraid to include various companies’ products while continuing with a two-trip program in most cases. “Farmers should plan for a two-pass program with a foundation herbicide down followed by a postemergence application where you are continually using multiple modes of action,” Byrum said. “Recognizing the places where we do have true resistance and not being afraid to recommend a competitive product is the best management practice,” Byrum said.
Glyphosate resistance is the most recognized problem, but Byrum said good planning can stop the spread of weed resistance to triazine and HPPD herbicides, too. All of this is part of Bayer’s Respect the Rotation education program that educates ag retailers, crop consultants and farmers about the need for herbicide mode of action rotation, as well as rotation of crops and traits.
