Influence Of Soybean Planting Date On Sudden Death Syndrome And Soybean Yield, E. A. Adee, C. R. Little, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

Sudden death syndrome (SDS) is a disease caused by the soilborne fungusFusarium virguliforme. This fungus prefers wet conditions and thus is usually most severe in irri­gated fields. Sudden death syndrome tends to be most severe on well-managed soybeans with a high yield potential. It also tends to be more prevalent on fields that are infested with soybean cyst nematode (SCN) or planted early when soils are wet and cool. Historical yield losses from this disease are generally in the range of 1–25%.

Soybean planting dates have been moving increasingly earlier in much of the soybean growing region, including …
