Brief Project Summary:

The project will develop rigorous, research-based guidelines for the use of biological control agents. Contans (Coniothyrium minitans) and Sporidesmium sclerotivorum degrade sclerotia, the long-term survival structures of Sclerotinia sclerotiorum, and they have shown efficacy against the disease in field trials in other regions of the United States. The study will evaluate how Contans should be incorporated to achieve maximum disease control. The project will also assess the potential of single applications of Contans and S. sclerotiorum to provide long-term, multi-year Sclerotinia control. The study will involve maintaining a large (36 acre) field experiment established in 2011 at the...

Information And Results
Final Project Results

Research conducted on Sporidesmium sclerotivorum showed that the biological control agent can be successfully isolated from soils in North Dakota but that considerable work will be required before spores of S. sclerotivorum can be increased on a commercial scale. Future research will focus primarily on testing Contans.

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.
