SUDDEN DEATH SYNDROME (SDS)
- SYMPTOMS: Leaves become brown, with veins remaining green; leaf blades drop off but petioles remain attached. Brown to gray discoloration of internal taproot.
- TIME OF ATTACK: During pod set and fill.
- CONDITIONS FAVORING: Cool, wet conditions throughout summer; well-fertilized fields; early planting/maturity; soil compaction; fields with history of SDS; co-infection with SCN.
- MANAGEMENT: Resistant cultivars; avoid early planting — wait until soils are warmer and drier; eliminate soil compaction.
