Brief Project Summary:

This project continues small plot research on herbicide-resistant weeds, including Palmer amaranth, horseweed (marestail), and the emerging problems of herbicide-resistant grassy weeds, including goosegrass, ryegrass, johnsongrass and barnyardgrass. The research assesses the best programs to control these troublesome weeds, using combinations of tillage, cover crops and herbicides with multiple modes of action. It also investigates the interaction of different traits and herbicides. At the same time, the project examines weed control failures on arms and elucidates if due to true herbicide resistance or some other factor. Efforts also consider if herbicide tolerance is developing to glufosinate, dicamba or 2,4-D.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
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.
