Palmer amaranth has grown into one of the biggest weed problems in soybean fields throughout the country. This research is exploring how biochemical activity in the weed cells can help manage herbicide resistance and point to traits that could improve cash crops. The research team compared biochemical changes in Palmer amaranth leaves exposed to common herbicide treatments, with a focus on GST and hydrogen peroxide levels. Glyphosate triggered the highest increase in GST levels in Palmer amaranth. However, when glyphosate combined with other modes of action, the leaf cells produced less GST.Key Benefactors: farmers, agronomists, weed scientists, herbicide companies
Expected Outcome: We are expecting the selection of herbicide treatments, which causes minimum increase in GST activity and thus, can slow down the evolution of non-target-resistance in Palmer Amaranth.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
