Spring wheat is mostly done flowering but for some of the fields that were planted late and are yet to reach flowering, these are still at risk for Fusarium head blight (FHB/Scab) to develop. The FHB prediction tool is showing moderate to high risk for FHB to develop for the northern half and the southeastern parts of the state. These fields should be protected from FHB by applying a fungicide when 50% of the plants are at flowering. The risk for FHB decreases with time after flowering. Some of the fungicides effective against scab include Caramba, Miravis Ace, Proline, and Prosaro.
