Brief Project Summary:

Charcoal rot, caused by Macrophomina phaseolina, is a disease of growing importance in the North Central Region, yet current management options are limited. In addition, this disease is more severe when plants are stressed by heat and dry conditions. New fungicide programs and fungicide products are marketed to reduce plant stress, but these products and programs have not been evaluated to determine their impact on charcoal rot development and yield. The goal of this research is to understand under what conditions fungicides may reduce plant stress and yield loss due to charcoal rot so that we may improve our recommendations to farmers interested in using fungicides to mitigate plant stress...

Information And Results
Project Deliverables

• Conducted research to determine fungicide efficacy on M. phaseolina growth and final yield of soybean
• Determined foliar fungicides applied to reduce plant stress and manage charcoal rot would not provide a consistent economic benefit to farmers.
• Observed that one fungicide seed treatment reduced final colonization rates of M. phaseolina compared to the non-treated control, meaning it could have efficacy against this disease
• Determined that fungicides applied in-furrow may reduce fungal populations in some environments, but not others, and the result of in-furrow applications on final yield was inconsistent.

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.
