Unfortunately, there are limited management options for SDS when it is discovered in a field. Because the disease originates from the root system, a foliar fungicide will not be effective. The areas of the field with disease have poorly functioning root systems; therefore, drought stress should be avoided. However, overwatering could increase the opportunities for other diseases and create more disease issues in parts of the field where SDS is not observed. Yield loss in the most affected areas can be severe and in some fields observed in 2014 reduced average yield by 30-40 Bu/acre.
Future management should involve the use of cultivars with some resistance to the disease. The fungus is well adapted to survive on residue from corn and soybean so an annual rotation with corn will not reduce disease. Other considerations should be to plant fields with a history of SDS later. Cooler and wetter soil conditions favor infection and colonization by the fungus that causes the disease. Additionally, evidence suggests SDS is more severe when soybean cyst nematode is present in the field. New seed treatment products, such as Ilevo (fluopyram), are labeled for control of SDS and may provide protection in fields where the disease has been a frequent problem.
