Due to wet soils and a late spring, many wheat and barley fields are maturing late this year in North Carolina. The FHB forecasting website shows medium to high risk across the Coastal Plain and Tidewater, but keep in mind the risk prediction is for wheat flowering today (or your chosen assessment date). Most small grain fields in North Carolina are in the jointing phase. Monitor your scab risk closely when your wheat is heading and your barley is in the boot. Wheat is susceptible to scab when it flowers. Barley is susceptible when heads emerge from the boot. Those are the growth stages at which to apply a scab-targeted fungicide IF risk is medium or high.

Welcome to the 2021 Fusarium Head Blight Prediction Center. The Prediction Center was renovated this past year and you may need to refresh your web browser to enjoy some of the new features. Please take a few minutes to familiarize yourself with the locations of help documents (“?” Button), assessment date selection (calendar), and model selection tools (menu button in the upper left).
The Prediction Center is currently focused on southern states where wheat is actively growing and likely moving through the jointing and flag leaf emergence stages of growth. The risk maps indicate the risk is currently low in most areas of LA, MS, AL and GA. Wheat in these areas of the country are likely to enter the vulnerable growth stages over the next two weeks.

Welcome to the Fusarium Head Blight Prediction Center, 2020. The system has undergone revisions for this year and it may help to familiarize yourself with the interface. The new interface provides a map-based estimate of disease risk for the current date. Users can select other dates of interest from the menu in the upper left portion of the interface. The date selected should correspond to times when your wheat is at or nearflowering, because the crop is most susceptible to infection at this growth stage. There is also a menu icon in the upper left corner that allows users to customize the model predictions for winter vs. spring wheat, and account for wheat varieties with different levels of genetic resistance to Fusarium head blight. The megaphone icon in the upper right activates this commentary display window. The selecting the colored buttons along the top of the commentary window displays state-specific commentary.
The focus of the prediction effort is currently on North Dakota, Northern Minnesota, where later planted spring wheat may still be at the heading and flowering stages of growth. The models indicate a moderate or high level of risk for susceptible wheat varieties in portions of North Dakota and western Minnesota. Growers in these areas should consult with local advisors to determine what other local factors that might also influence the risk of disease.
