Leveraged Funding (Non-Checkoff):
All universities on this proposal contribute in-kind funding in the form of faculty salary and fringe benefits and a waiver on university indirect costs or overhead (typically calculated at over 45% for most institutions). The waiver for indirect costs and overhead for this proposal is approximately $228,600 ($508,000 x 45%). The in-kind contribution for faculty salary and fringe benefits varies by assigned faculty effort at each institution, but could be conservatively estimated at $50,000. The “Take Action” proposal that has been funded by USB for weed management education could also be argued as leveraged funds since there is a collaboration between this research proposal and their extension efforts.

Information And Results
Project Deliverables

• Provide data and reports detailing the impact of harvest weed seed control strategies which may include destruction of weed seed as it exits the combine. Educate weed management decision makers on the impact of harvest weed seed control compared to other management tactics (July 2019).
• Improve herbicide recommendations to terminate cover crop growth in the spring (November 2017) and reduce residual herbicide carryover for fall planting to allow for more successful adoption of cover crops as part of the BMPs for herbicide-resistant weeds (June 2018). Develop a list of soil residual herbicides with the greatest performance and compatibility to use in high residue cover crop systems (November 2019). This information is incorporated into the weed control guides distributed by each state that are updated annually in the fall of the year.
• Provide data and reports detailing the influence BMPs for Amaranthus species may have on management of other problematic weed species. Disseminate information on how BMPs should be altered for problematic weeds outside of the pigweed family (July 2019) and include in the Take Action factsheets which are updated frequently.
• Knowledge to educate growers on the impact of tank contamination or off-target doses of 2,4-D and dicamba, describe the potential interaction of these herbicides through tank contamination on soybean, and integrate the research findings on soybean injury and yield impact into educational materials/venues on proper sprayer cleanout procedures and spray drift mitigation (April 2018).
• Regional and state information to help educate soybean producers on the potential/frequency for air temperature inversions that contribute to off-target herbicide movement (November 2019). This information will be presented crop advisors in CCA/Crop Conferences held each fall in every state and to farmers during the winter meeting season.

Final Project Results

Updated December 2, 2018:

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.
