Information And Results
Project Deliverables

1. Define the persistence of pigweeds in the soil seedbank across vast geographies and use this information to promote draw-down of the soil seedbank (September 2017).
2. 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).
3. Improve herbicide recommendations to terminate cover crop growth in the spring 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).
4. Understand 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).
5. 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 (May 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.
