Brief Project Summary:

Waterhemp and Palmer amaranth evolved multiple resistances to a number of herbicides across the Midwest. This warrants studies to monitor their populations in Kansas for development of glyphosate, 2,4-D, and/or dicamba resistance. A key aspect in predicting the evolutionary trajectory of herbicide resistance is to understand the mechanisms. This research aims to better predict and manage 2,4-D resistance in waterhemp and Palmer amaranth by understanding the level and the mechanism of resistance. This project also aims to investigate various pre-herbicide programs alone or in conjunction with post-glyphosate plus dicamba applications for controlling glyphosate-resistant Palmer amaranth in Roundup Ready 2 Xtend soybeans.

Key Benefactors:
farmers, agronomists, applicators, ag retailers, extension specialists

Final Project Results

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.
