Soybean yield losses from SDS can range from only slight to 100%. Actual yield loss depends on when plants become infected.

Infections that occur early can result in pod abortion, reduced seed number and seed size. Infections that occur after flowering will not have a significant impact on yield.

SDS disease tends to be most severe on well-managed soybeans with a high yield potential.
