Brief Project Summary:

Palmer amaranth is the most troublesome weed in soybean production in North Carolina due to its ability to produce dense and competitive populations and its resistance to herbicides like glyphosate and ALS-inhibitors. Recently, research identified a glufosinate-resistant Palmer amaranth population. This project develops a rapid bioassay to identify glufosinate-resistant Palmer amaranth populations and a monitoring strategy for soybean-producing areas in North Carolina. This will help soybean growers avoid losing the effectiveness of one of their most important weed control tools, as eradication can be implemented before the resistance trait is dispersed in the weed population.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

Studies have been initiated to rapidly monitoring and testing for resistancein pigweed species. Surveys have been given at County Extension meetings throughout the state to determine use of and challenges utilizing glufosinate. In addition, test populations have been identified, are being propagated, and protocols have been identified to begin the identification studies.

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.
