Brief Project Summary:

Effective pigweed herbicides are declining due to the emergence and rapid spread of herbicide resistance traits, combined with the lack of new herbicides. Waterhemp and Palmer amaranth have a dynamic repertoire of resistance for eight modes of action, making them focal species for herbicide research. Through this project, researchers will conduct a statewide survey to screen pigweed populations for glyphosate, PPO-inhibitor, and ALS resistance. This project will provide a distribution map of HR genotypes, a DNA archive for developing additional tests for herbicide-resistance genotyping panel, and a comparative analysis of genotypes and whole-plant herbicide trials.

Key Benefactors:
farmers, agronomists, applicators, extension specialists

Information And Results
Project Deliverables

Combining genotyping and greenhouse data will help describe the particular types of HR pigweed populations that exist in the state, including western North Dakota. The project will look at additional molecular tests for HR detection in pigweeds, which will remain available to the agricultural community once described. Results will be communicated through presentations to growers and potential updates to NDSU publications or other resources.

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.
