Sudden Death Syndrome (SDS) is caused by the fungus, Fusarium virguliforme. The life cycle of SDS is denoted by two distinct periods of infection of soybean roots in the early spring, followed by advanced disease development during flowering. SDS infects soybeans in the spring under the cool, wet soil conditions that are often associated with early planting.

Symptoms of SDS are showing up in a few areas. Initial symptoms include yellow spots between the leaf veins that coalesce into large areas of interveinal chlorosis and necrosis.
