Brief Project Summary:

Metribuzin is a broad-spectrum residual herbicide that provides a high level of control of Palmer amaranth. Soybean varieties differ in tolerance to metribuzin; hence, annual testing of available varieties was routine prior to Roundup Ready soybeans. Now that preemergence, residual herbicides are once again a major component of weed management in Arkansas soybeans, screening of soybean varieties for tolerance to metribuzin is again needed. The goal of this project is to screen all varieties entered in the Arkansas variety trials for tolerance to metribuzin, allowing growers to make informed decisions as they select varieties and develop robust weed control programs.

farmers, agronomists, extension agents, soybean breeders, seed companies

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.
