This project has three major components. One component is the continuation of a long-term study to determine the effect of different sequences of SCN-resistance sources on the dynamics of SCN population densities and their virulence phenotypes (HG Types). This study is helping to develop management strategies to avoid SCN resistance failures. A second component is designed to determine effect of organic and chemical fertilizers and tillage on SCN population densities and soybean yields. A third component is a survey to determine frequency of occurrence and extent of SCN infestation and the frequency of various HG Types and their distribution in Minnesota.
