Fusarium Head Blight (FHB) is a plant disease caused by fungi, primarily Fusarium graminearum. It affects cereal crops, especially wheat and barley, leading to reduced yields and poor grain quality. The disease is characterized by the bleaching of the heads, shriveled grains, and the presence of pink or white fungal growth. FHB can also produce harmful mycotoxins, such as deoxynivalenol (DON), which pose health risks to humans and livestock. Effective management strategies include crop rotation, resistant varieties, and proper field management practices to minimize the impact of this disease on agricultural production.
