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 appearance of bleached spikelets and can produce harmful mycotoxins, which pose health risks to humans and livestock. FHB thrives in warm, humid conditions, making it a significant concern in many agricultural regions. Farmers can manage the disease through crop rotation, resistant varieties, and proper field management practices. Early detection and intervention are crucial to minimize its impact on crops.
