Brief Project Summary:

As herbicide resistance continues to spread, this project aims to determine the heritability of HPPD resistance in common waterhemp. It will also explore if hybridization is common between common waterhemp and Palmer amaranth. Seed variability resulting from greenhouse studies of weed seed will uncover if postzygotic reproductive barriers exist which could impact the field establishment of these types of weeds.

Key Benefactors:
farmers, agronomists, Extension agents, weed scientists

Information And Results
Project Deliverables

1. Recommendations to growers for management of the most important soybean pest complex (weeds) that is evolving new herbicide resistance and potentially new weed species.
2. ISU Extension and ISA collaborative publications describing the results of this research.
3. Information will be made available in webpages, newsletters, blogs, radio presentations, and used in grower meetings.

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.
