"Sudden death syndrome (SDS) is one of the most important diseases of soybean in the Midwest. First discovered in Arkansas in 1971, SDS has spread throughout most of the North Central Region, including Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Mississippi, Missouri, Nebraska, Ohio, and Tennessee. SDS is most severe when soybean is planted early into cool, wet soils and when heavy midsummer rains saturate the soil. The fungus that causes SDS is now present in nearly all Indiana soybean fields, placing plants in high moisture areas of fields at risk for the disease."
