Outlook on Weed Management in Herbicide-resistant Crops: Need for Diversification
The use of glyphosate in glyphosate-resistant (GR) crops has been the dominant new weed management technology for the last 15 years. The technology enabled a heavy reliance on glyphosate that ultimately resulted in the widespread evolution of GR weeds. Now growers cannot survive using glyphosate alone, but no currently available herbicide can replace glyphosate. To maintain the levels of weed control needed for successful crop production, growers will have to use a combination of technologies. These technologies will include trait-enabled and naturally selective herbicides as well as diverse mechanical and cultural practices. If done properly, this approach will be effective and sustainable.
