小麦纹枯病是一种世界分布的土传真菌病害。近年来该病在我国冬小麦种植区发生普遍,已成为小麦高产、稳产的重大障碍~([1])。河南省是我国小麦主产区之一,近几年小麦纹枯病的发生面积连续在300万hm~2左右,危害严重~([2])。目前,尚未发现高抗纹枯病的小麦品种,控制该病害主要依靠药剂种子处理结合春季喷雾来进行,所用药剂包括井冈霉素和以三唑酮为代表的三唑类化学药剂。随着

Wheat sheath blight is a worldwide distribution of soil borne diseases. In recent years, the disease is common in the winter wheat growing areas in China and has become a major obstacle to high yield and stable yield of wheat ~ ([1]). Henan Province is one of the major wheat producing areas in China. In recent years, the occurrence area of ​​wheat sheath blight has been continuously around 3 million hm ~ 2, which is seriously devastating ([2]). At present, no wheat varieties resistant to Sheath blight have yet been found. The disease control mainly depends on seed treatment with spring spray. The drugs used include validamycin and triazole chemicals represented by triadimefon. along with
