The Southeastern U.S. Fusarium Head Blight Epidemic of 2003

C. Cowger and A. L. Sutton

October 2005


Fusarium head blight (FHB) caused unprecedented losses to southeastern U.S. wheat producers and millers in 2003. Detailed surveys on disease incidence and severity were not conducted on the epidemic. Therefore, the first goal of this study was to develop a picture of the distribution and impact of the southeastern epidemic. The second goal was to investigate the relationship of 2003 FHB incidence to weather influences in the pre- and post-flowering periods, in order to gather clues on why the epidemic was severe in that year and region.
