Sudden death syndrome of soybean (SDS) and soybean cyst nematode (SCN) are two pest issues that have the potential to cause significant yield loss on an annual basis in Indiana. SDS was widespread in north-central and northwest Indiana in 2010, and many producers are interested in understanding how to manage this disease, especially when research suggests that the population size and genetic profile of SCN within a field may influence expression of SDS.

The overall objective for this research is to continue this research in 2012 and further improve the understanding of the interaction between SDS and SCN. To more fully understand this interaction, we propose two research objectives...
