Spring wheat is at heading and some of the fields are at flowering growth stage. Current weather conditions are conducive for Fusarium head blight or scab to develop for the majority of the state. The FHB prediction tool is a showing high risk for FHB in susceptible cultivars for more than 1/2 of the state. A triazole fungicide applied at flowering is advisable to protect wheat from FHB and DON.
