New herbicide technology needed
The increasing prevalence of weeds with resistance to one or more herbicides, including glyphosate, is increasing the cost of row crop production in the US. Soybeans and cotton are the most susceptible of these crops as they have fewer chemical options for controlling key weeds which are developing resistance to multiple herbicides.
While chemical herbicides will remain the primary control mechanism of choice, tillage is likely to increase. Glyphosate will continue to be an important platform for weed control; however, a variety of modes of action will need to be made available in order to supply much more robust soybean weed management programs.
Concurrently, new seed products will be required to increase chemical diversity while allowing farmers to continue low tillage practices. In addition, a widespread return to older chemistries to add diversity to herbicide rotations is likely.
