Sudden Death Syndrome (SDS) is caused by the fungus, Fusarium virguliforme. Favorable conditions for SDS infection and symptom development can be divided into two distinct periods: infection of soybean roots in the early spring and significant rainfall during flowering.

Additionally, if conditions are relatively cool and wet during soybean flowering, the initial infection further develops and advances into the conductive tissues of the roots and lower stem.
