Project Summary

The objective of this study is to develop additional information for better managing the soybean cyst nematode. The project is organized with 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).

~ A second component is to determine effect of organic and chemical fertilizers and tillage on SCN population densities and soybean yields; and

~ The third component is to conduct approximately 45 on-farm trials to establish the level of SCN virulent biotypes that can overcome existing resistance genes. These on-farm trials will also be able to provide an estimate of yield loss due to SCN infestations. The intent is to develop a field bio-assay technique that can be used as an alternative to a laboratory HG type analysis.

Project Objectives

1. Determine the effect of different sequences of SCN-resistance sources on the dynamics of SCN population densities and their virulence phenotypes (HG Types).
2. Determine effect of organic and chemical fertilizers and tillage on SCN population densities and soybean yields.
3. Conduct approximately 45 on-farm trials to establish the level of SCN virulent biotypes that can overcome existing resistance genes.
