Brief Project Summary:

Currently there are three primary options for managing soybean cyst nematode: growing nonhost crops, such as corn, growing SCN-resistant soybean varieties and using nematode-protectant seed treatments. This project increases the competitiveness of Iowa soybean farmers through better and more sustained management of SCN. Resistant soybean varieties vary significantly in how well they suppress SCN reproduction, and results of assessing SCN reproduction on resistant varieties in the greenhouse do not accurately predict nematode control in the field. In this project, resistant varieties are evaluated for agronomic performance and nematode control in field experiments throughout Iowa.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
Project Deliverables

There will be numerous deliverables and outcomes emanating from this project:
• annually updated report of results from the SCN-resistant soybean variety trial experiments (direct mailed to 70,000 Iowa farmers and agribusiness personnel)
• annually updated list of SCN-resistant soybean varieties for Iowa soybean farmers
• articles in the Iowa State University online Integrated Crop Management News newsletter
• articles in the Iowa Soybean Association electronic Advance newsletter

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.
