Winter wheat in South Dakota ranges between flag leaf and heading. One disease that is managed after wheat heading is Fusarium head blight (FHB or scab). This disease is promoted by warm and wet weather. Currently most of the areas in the state are tending towards being dry and therefore the risk for FHB at this time is low according to the FHB risk model. Growers are encouraged to keep monitoring the weather conditions and the FHB risk tool to determine the need for applying a triazole fungicide at wheat flowering to control FHB.
