Brief Project Summary:

Weed populations expressing resistance to glyphosate and other herbicides have become more widespread in soybeans and difficult to manage. Waterhemp, giant ragweed, horseweed, and morning glories are commonly found and in 2013, researchers documented the presence of Palmer amaranth in over 20 counties. No-till systems and the repeated use of similar herbicides have led to herbicide resistance in these weeds. In no-till soybeans, glyphosate-resistant weeds pose a serious problem to growers. This project will determine the presence and distribution of glyphosate- and other herbicide-resistant weed biotypes.

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

Information And Results
Project Deliverables

Knowledge of the presence and distribution of glyphosate and other herbicide resistant weed biotypes in Indiana.

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.
