Brief Project Summary:

Weed control is a continual issue facing soybean producers in Oklahoma. With the commercialization of Roundup Ready (glyphosate-resistant) soybean varieties in the mid-1990s, weed control was greatly improved and simplified compared with conventional soybean production. As a result of the improved weed control, many producers have begun post emergence-only (POST) herbicide programs and rely extensively on glyphosate for preplant and POST treatments. However, in recent years, many producers have begun to struggle to satisfactorily control weeds in a timely manner using POST-only herbicide programs because of labor and time constraints and the increasing prevalence of herbicide-resistant...

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.
