Sudden death syndrome (SDS) of soybean was first discovered in 1971 in Arkansas and since then has been confirmed throughout most soybean-growing areas of the United States. SDS is a fungal disease that also occurs in a disease complex with the soybean cyst nematode (SCN, Heterodera glycines).


SDS is among the most devastating soil-borne diseases of soybean in the USA. When this disease occurs in the presence of SCN, disease symptoms occur earlier and are more severe. Disease symptoms are most pronounced after flowering.
