Brief Project Summary:
Non-GMO soybean is an important market for Michigan farmers. One of the greatest impediments of non-GMO soybeans is good weed control. As herbicide-resistant horseweed (marestail) continues to plague farmers, researchers plan to demonstrate non-GMO weed management programs between no-till and conventional tillage soybean. The research and demonstration plots provide growers with hands-on information on effective, sustainable weed control strategies. Additionally, alternative cost-effective weed control strategies may encourage growers to use other methods to help delay the evolution of glyphosate and multiple-resistant weeds. Information generated from this research is included in fact sheets as handouts and resources for farmers.

Project Summary

Project Objectives

Objectives:
1) Continue to develop and evaluate the effectiveness of several non-GMO weed control programs in tilled and no-till soybean.
2) Determine the economic returns of these weed control programs.
3) Provide this information specifically to non-GMO soybean producers through a web-accessible fact sheet, a field tour and at winter meeting specific to weed control in non-GMO crops.

Project Deliverables

Over the past eleven seasons, with the exception of this last summer due to COVID restrictions, we have been able to highlight our non-GMO weed control programs as a part of the annual MSU Weed Control Tour held in June at the MSU Agronomy farm. In 2019, over 200 growers, agronomists, sales representatives, and extension educators attended this field tour. Additionally, specific non-GMO soybean tours have been held that afternoon with over 20 growers and weed control advisors of non-GMO soybean in attendance for more in-depth discussion of the non-GMO research plots. Since we were not able to hold in person meetings this year, we have video and pictures that we will be putting together for non-GMO grower meetings of this year’s plots.

• Information generated from this research has also been put into usable fact sheets accessible by the web (http://www.msuweeds.com). These fact sheets have also been available to growers who have attended non-GMO soybean meetings in the winter months. In the past, we have spoken to over 100 farmers who have been or are interested in growing non-GMO soybean at non-GMO specific meetings. In 2020 we spoke to farmers at two meetings one in Zeeland and one in Frankenmuth. Unfortunately, this year we won’t be able to hold in-person meetings, but we are looking forward to holding some virtual discussions with non-GMO soybean farmers that will highlight results from these trials.

Final Project Results

Benefit To Soybean Farmers

This research provides growers with information on effective, sustainable weed control strategies in non-GMO soybean. The economic analysis is used to determine the cost-effectiveness of these strategies. With the increasing cost of soybean seed, particularly seed with herbicide-resistant traits this information will provide growers with alternatives that may enhance their economics and potentially provide growers with alternative strategies for weed control to help delay the evolution of glyphosate-resistant weeds. This information could potentially open the doors for other growers to get into the production of soybeans were a premium could be realized; therefore, improving overall grower profitability

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.
