Two projects will be conducted to reduce herbicide-resistant weed impact on soybeans while enabling grower freedom to select soybean herbicide resistance traits. The first project investigates suspected herbicide-resistant weeds collected through surveys and submitted by farmers and ag professionals. Researchers will confirm the presence and distribution of herbicide-resistant Palmer amaranth, waterhemp, horseweed, and giant ragweed, and other weeds resistant to glyphosate and other herbicides such Liberty Link (LL) and Roundup Ready Xtend (RR) soybeans. The second project focuses on soybeans resistant to both glyphosate and glufosinate in a core trait stack (RR/LL). The objective is to develop effective weed management strategies in non-GMO soybeans and in stacked RR/LL soybeans.
