Brief Project Summary:

Horseweed (marestail) continues to be the #1 weed escape in Michigan soybean fields. Fall-seeded cereal cover crops provide early-season horseweed suppression and delaying cover crop termination reduces horseweed biomass. In this project, researchers expand upon previous work to examine the following objectives: evaluate the effect of a fall-planted cereal rye terminated one week before soybean planting and one week after soybean planting for the suppression of glyphosate-resistant horseweed in no-till soybean; determine the contribution of soybean row width on horseweed suppression; compare the integrated approaches of cover crop and row width with and without a post-herbicide application on horseweed management.

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.
