Soybean Sudden Death Syndrome

Reports across the midwest (Nebraska, Iowa, Kentucky)  indicate that soybean sudden death syndrome (SDS) is becoming prevalent in some areas.

The OSU Pathology group has an excellent resource on crop diseases available at the Ohio Crop Disease website.  Below is from the section on SDS:


  • begin as small pale green to yellow circular leaf spots
  • brown to tan areas develop between the veins
  • pith is white
  • root decay and discoloration of roots and crown


  • high soil moisture during late vegetative growth stages
  • SCN can increase severity of foliar symptoms


  • fungal spores overwinter and survive for years in the soil
  • spores have been found on the cysts of SCN


  • reduce SCN populations
  • increase soil drainage by tiling or tillage
  • long crop rotations – soybeans only once every three years
