Project Summary

This project has a number of objectives. One objective is to determine the effect of different sequences of SCN-resistance sources on the dynamics of SCN population densities and their virulence phenotypes (races or HG Types). A second objective is to determine effect of manure and chemical fertilizers on SCN population densities, SCN community structure and food web, the parasitism of nematodes by fungi, the level of nematode-suppressiveness and soybean yields. A third objective will be to determine the relationship between SCN suppression and the SCN community structure and food web.
