Brief Project Summary:

With the increasing interest in the use of fungicides for soybean production, there is an immediate need to better predict if/when applications will be profitable. Each year farmers are provided new fungicides or novel uses for existing products. The U.S. agrichemical industry continues to promote application of foliar fungicides to soybean to increase overall "plant health". But the economic benefits of such applications are inconsistent and not well documented. With high market prices and the marketing push from industry, soybean farmers in Iowa feel pressure to apply foliar fungicides and insecticides even in the absence of significant disease or insect pressure.

Final Project Results

• During the first season we have established an in-furrow study evaluating fungicides with and without starter fertilizer. We also are collaborating with several other colleagues across the U.S. who are completing the same experiment;
• We continued a statewide fungicide trial, which was at 7 ISU research farms. This year’s trial included over 20 fungicide treatments. The data is being analyzed;
• We are working with ISA’s OFN to collect disease, leaf wetness, and additional satellite imagery from each field;
• We lined up additional support from BASF to collected aerial images, leaf wetness and disease severity at different times during the season to see how this information relates to yield responses to fungicides; and
• A summary of soybean fungicides for Plant Management Network this season was completed and several field days, newsletter articles, and media interviews included information about our research on fungicides.

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.
