Soybean growers continue to look for ways to decrease input costs, and herbicide resistant weeds continue to affect yield while new resistant biotypes continue to evolve due to limited post-emergent herbicide options. Continued grower investment in “new” soybean herbicide tolerance genetics, which require increased technology fees per unit of soybean, are potentially unnecessary if conventional herbicides are able to economically compete. Modern soybean genetics provide herbicide tolerance to increase post-emergence weed control options. However, misapplication and overuse of post-emergent herbicides has led to selection pressure in waterhemp populations. Soil applied residuals are effective...
