Soybean sudden death syndrome (SDS) is a fungal disease causing foliar necrosis and early leaf drop. SDS can be a significant factor in soybean yield loss and has been found in fields across Iowa. The fungus is a good saprophyte and can grow well on plant debris in the field. The disease often is worse following corn. Although there is no complete resistance to SDS available in soybean, disease resistance is an important part of SDS disease management.
