Wheat in southern Indiana is heading and may begin flowering this weekend or in the coming week. Currently, the risk is low across southern Indiana, but the recent and forecasted rain may increase risk for wheat in this area in the coming week. Producers in southern Indiana should be prepared to apply a fungicide. 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.
