Wheat crop is flowering or towards the end of flowering in Maryland. With high humidity and moderate temperatures, the risk for Fusarium Head Blight in the region continues to be high (See the attached FHB risk map). The past week with high winds and rain may have made it difficult to spray fungicides for Fusarium head blight. Still there is time of around 4-5 days to spray appropriate products to reduce FHB and associated DON content. The most effective products are Caramba, Prosaro, and Proline. Aerial application at 5 gallons per acre or ground application at 15 gallons per acre is recommended. For ground application, rear and forward facing nozzles should be angled down 30 degrees from horizontal with 300 um droplet size.
