Brief Project Summary:

Marestail has become a major weed for soybean producers in Kentucky and throughout a broader geographic range. Its small seed size make this weed particularly troublesome for no-till soybean growers; its prolific, wind-blown seed can disperse far between fields and adjacent natural areas; and its extended emergence period complicates management efforts. In addition to all of these traits, glyphosate resistant biotypes are now widespread throughout the state. Thus, management tactics that integrate other chemical options with cultural practices like the use of cover crops are desirable for this species.

This project examines the integration of fall- and spring-applied herbicides with...

Project Deliverables

One direct outcome of this project will be a better understanding of the efficacy of herbicide applications made in cover-cropped fields. This will benefit Kentucky growers who currently utilize cover crops or plan to utilize them in the future. Research conducted for this project will form the basis of Austin Sherman’s master’s thesis; Austin is a new graduate student advised by Dr. Haramoto. In addition, data generated from this project will be used to leverage federal grant dollars through a collaborative project in development with other researchers throughout the Mid-south and Midwest regions.
These findings will be disseminated in Austin Sherman’s thesis and in the peer reviewed literature. They will also be shared through extension programming about the integration of herbicides with cover crops to manage weeds.

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.
