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. Additionally, they will evaluate the effects of ragweed extract seed coat and arbuscular mycorrhizae, additives that have been shown to reduce SCN infestation, as well as a new commercial nematicide seed treatment, Saltro.

Key Benefactors:
farmers, agronomists, extension specialists

Information And Results
Project Deliverables

• Growers test their soils for SCN and receive information on management strategies specific to
their fields.
• Potential of ragweed extract as a seed additive determined.
• Additive effects of ragweed extract with arbuscular myhorrhizae and Salto fungicide
determined.

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.
