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. The disease tends to be most severe on well-managed soybeans with a high yield potential.
The appearance of SDS symptoms at early pod fill is reportedly more damaging than its appearance at a later stage of plant development.
Yield reduction is caused by the reduced photosynthetic area, defoliation, flower and pod abortion, and reduced seed size.
