Brief Project Summary:

Herbicide resistance in Palmer amaranth is a continuing concern for soybean producers in North Carolina. We have been among the first to deal with ALS-resistance, glyphosate-resistance, and PPO-resistance. We want to continue to rapidly identify populations of concern and maintain a baseline of efficacy across the state. Surveys have been conducted across the state in 2010 and 2015, and we would like to continue them in 2022. We had plans to collect seed in 2020 and 2021, however limitations kept that from happening. By collecting seed in 2022 and evaluating the current herbicide options in 2023, we can identify areas of concern, and more importantly, confirm areas we can continue to utilize...

Information And Results
Project Deliverables

Detailed material on resistant Palmer amaranth populations should be developed and made available through Extension presentations, Extension fact sheets, popular press articles, Extension videos, and other appropriate venues so growers have a greater understanding of what issues are currently here so effective control decisions can be made. In addition, this will be a graduate student project and an end product will be a well trained student with a strong understanding of herbicide-resistance issues in North Carolina.

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.
