Fusarium head blight (FHB), mainly caused by Fusarium graminearum, is a major disease affecting wheat (Triticum aestivum L.) worldwide. The disease leads to bleached heads and shriveled, tombstone-shaped kernels contaminated with mycotoxins, which can result in significant yield losses and reduction of grain quality. This study assessed fungicide effectiveness and application timing for managing FHB in the soft red winter wheat cultivar ‘Shirley’ in Georgetown, Delaware. Disease incidence and severity, Fusarium-damaged kernels, yield, and deoxynivalenol concentrations were measured across treatments. Findings from this research will support U.S. wheat growers in improving FHB management practices to minimize yield loss and mycotoxin contamination.
