Wheat in central and northern Indiana is flowering or will soon be flowering. Currently, the overall risk for scab is predicted to be low, but scattered rain across the state and high humidity may increase risk locally. Producers should be prepared to apply a fungicide if weather conditions are humid and rainfall is predicted. Fungicide applications should be applied at early flowering to be most effective. Indiana research indicates that applications of the fungicides Prosaro and Caramba are most effective at managing FHB if they are applied at early flowering (Feekes growth stage 10.5.1). Other products are available, but may not be as effective.
