Interpretive Summary: Fusarium head blight (FHB) is a major disease of wheat worldwide. Correct diagnosis is critical to make management decisions about this disease problem. This diagnostic guide describes the pathogens involved in the disease in the Pacific Northwest, along with how to identify them, the host range and geographic distribution, and what management practices are appropriate.
Technical Abstract: Fusarium head blight (FHB) is a devastating disease of wheat (Triticum aestivum) worldwide. In the Pacific Northwest of the United States, this disease is caused by Fusarium species including Fusarium graminearum Schwabe sensu stricto, F. culmorum (Wm. G. Sm.) Sacc., and F. pseudograminearum O’Donnell & T. Aoki. This diagnostic guide provides information on the pathogen, signs and symptoms of disease, host range, and geographic distribution, with a focus on the relevant pathogens for the Pacific Northwest. A discussion of the mycotoxins produced by the pathogens as well as management strategies are also presented. Proper diagnosis will allow practitioners greater opportunity to adequately control FHB disease.
