Brief Project Summary:

The soybean cyst nematode is difficult to manage because it inhabits the soil and can survive up to 10 years without a host, therefore it is not practically possible to eradicate SCN. Management of SCN requires a concerted effort that includes grower awareness, use of resistant/tolerant soybean cultivars, supplemented by nematicide seed treatments where SCN population density in the soil is high. Researchers will offer free SCN testing for SD soybean producers with this project. They will also investigate nematode-infecting viruses that could be used as biological control agents against SCN. This may result in adopting effective SCN management practices and development of alternative management approaches.

Key Benefactors:
farmers, agronomists, extension specialists

Information And Results
Project Deliverables

Objective 1. Create awareness and continue to offer sponsored SCN testing for South Dakota producers. Growers, agronomists, and crop consultants submit soil samples for SCN testing free of charge. Results from SCN testing include recommendations for SCN management leading to prevented yield loss caused by SCN.

Objective 2. Test several plant extracts as potential nematicides against SCN. Plant extracts found to be effective against SCN are recommended for further characterization and possible development into soil/seed treatments.

Objective 3. Determine nematode-infecting viruses for potential use as biocontrol agents. Viruses infecting nematodes are identified. These viruses could be used as biocontrol agents to manage SCN.

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.
