We will investigate in three locations (Chicago area and Champaign) to evaluate if Japanese beetles are deterred by phenylalanine and quercetin or products derived from phenylalanine when applied directly to seeds or leaves at approximately 2 weeks after planting (before peak beetle period). From the process of field and laboratory experiments, we will identify soybean genotypes that are high-yielding but naturally able to better repel predation by Japanese beetles with these treatments.
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.
