RALEIGH, N.C.–Wheat scab risk is moderate to high for wheat flowering now in coastal NC counties. These include south Columbus, Carteret, Pamlico, east Craven, southeast Beaufort. Wheat is likely at earlier growth stages in coastal counties north of those. Risk remains low for the Coastal Plain and other regions of the state.
If risk in your area is moderate to high and wheat is flowering, apply fungicide at early flowering or up to 7 days later. Do not apply a strobilurin-containing fungicide. The most effective products are Caramba, Prosaro, and Proline.
Aerial application may be profitable. For ground application, rear- and forward-facing nozzles should be angled down 30 degrees from horizontal. For more information on wheat scab risk in your region, visit the wheat scab risk model to assess risk based on weather conditions and cultivar resistance.
