Brief Project Summary:

This project is developing controls for major Soybean Diseases in ND and obtaining information on the biology of soybean pathogens that will help growers understand how diseases develop and what practices to use to prevent and reduce losses from such diseases.

Final Project Results

We used both traditional and molecular methods of identifying the fungi in those plants and determined that the disease was not sudden death syndrome. We believe the symptoms were caused by F. solani, a common Fusarium infecting soybean roots in this area, in combination with some unknown soil or stress factor. As of yet, sudden death syndrome has not been verified in North Dakota.

In 2010, soybean leaves were collected from 200 soybean fields in 25 N.D. counties and analyzed for eight different soybean viruses in a cooperative study with Dr. L. Domier, a USDA virologist in lllinois. The results of that study were reported previously. However, Dr. Domier continued to analyze the leaves from that collection using different techniques and recently found one soybean field where plants were infected with soybean dwarf virus, a virus not previously detected in North Dakota.

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.
