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.
