Weeds continue to challenge corn and sorghum producers across Kansas. With the development of herbicide-resistant weeds, including weeds resistant to glyphosate, continued development of tools for weed control will be essential. The emphasis of this research program is to work with stakeholders to improve existing and develop new technologies for managing weeds in corn, sorghum, sunflower, and other crops as needed. It is imperative that these programs are cost-effective and environmentally friendly.
