Brief Project Summary:

Assessing herbicide resistance in weeds can be a time- and space-consuming task. For a thorough herbicide resistance test, it could take six months or more from the initial herbicide failure in the field until potential resistance is confirmed. Researchers will collect a diverse sample-set of common herbicide-resistant weeds from Michigan soybean fields. Through a series of lab techniques that look at a weed’s extracted DNA code, researchers could preemptively identify whether a herbicide will be effective or not. The process takes several days between getting the plant tissue and finding the results, rather than the traditional method, which takes several months.

Key Benefactors:
farmers, weed specialists, agronomists, extension specialists, applicators

Information And Results
Project Deliverables

Data about the type and extent of resistance of these keys weed species will be delivered to soybean growers and crop scouting companies in a short (<1 week) turn around allowing for growers to alter herbicide applications if necessary. Furthermore, the assays data will be discussed at MSU extension meetings and shared with MSPC to gage the extent of herbicide resistance issues in Michigan soybean fields as well as the viability of offering molecular diagnostics and/or expanding to other modes-of action.

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.
