The U.S. Wheat and Barley Scab Initiative (USWBSI) is pleased to announce the publishing of its 2024 Fusarium Head Blight Disease Impact Update. This year, commentary from 32 state specialists indicated Fusarium head blight (FHB, also known as scab) was more prevalent this season compared to recent years, primarily for those in the northern and eastern states of the U.S. A few states reported dockages due to increased levels of deoxynivalenol (DON) and yield reductions. The southern regions, along with the Pacific Northwest, had more limited cases of FHB due to weather events not coinciding with growth stages when the crop is vulnerable to infection. Where FHB was prevalent, the FHB Risk Tool predicted high risk, and growers were able to mitigate losses through the use of fungicide applications.
