Soybean yield losses from SDS can range from only slight to 100%, depending on variety and stage of crop development when the symptoms first appear.
Appearance of the disorder at early pod fill is reportedly more damaging than its appearance at a later stage of plant development.
Yield reduction is the result of reduced photosynthetic area, defoliation, flower and pod abortion, and reduced seed size.
SDS disease tends to be most severe on well-managed soybeans with a high yield potential.
