Fusarium head blight (FHB)

Some of the winter wheat in SD is starting to head. This wheat growth stage is the best time to start monitoring the risk for Fusarium head blight (FHB). The most important risk factor for FHB is rainfall when wheat is at flowering. The current predicted risk for FHB for SD is mainly low for the most parts of the state. A moderate risk is predicted for portions of Miner, Lake and McCook counties as well as southwest counties. Keep monitoring the risk for scab until wheat is done flowering. For areas predicted to have a moderate or high risk of FHB, a triazole fungicide applied at flowering is recommended.
