Brief Project Summary:

Private industry has made significant progress in the development of biological fungicides for row crops. The goal of this proposal is to evaluate the effectiveness of potential biological control products on sudden death syndrome (SDS) and white mold, two of the most important fungal diseases of soybean.

Information And Results
Final Project Results

Efforts were made to evaluate biological control products against SDS and white mold by establishing multiple locations in Iowa, Illinois and Minnesota. Multiple field trials were established in Iowa, Illinois and Minnesota in 2013 to evaluate biological control products for their effectiveness against SDS and white mold treatments were made on production farms with strip plots or on university farms of the participating states. Treatments were made on production farms with strip plots or on university farms of participating states. Yield data from university farms have been collected and analyzed. Yield data from commercial farms are being analyzed. Results on yield data from university farms show that plots treated with biological control product(s) had less disease and higher yields compared to control. Remote sensing images taken for plots on commercial farms where treatments had applied showed differences between treated area and adjacent area (control).

The data is encouraging in that 2013 was a season with delayed planting, which was unfavorable to SDS and several other soil borne diseases, suggesting the differences could be greater in years favorable to soiborne diseases.

Green house experiments were carried in both Iowa State University and University of Illinois to determine the effects of bacterium strain on the reduction of soybean sudden death syndrome. Significant progress has been made. In 2014, we have made plan to repeat similar field experiments which will be carried in all three states.

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.
