Since the late 1970s, wheat powdery mildew has risen to the major disease in wheat growing areas in China, seriously restricting wheat production [1]. Northern coastal and Huaibei area, wheat powdery mildew occurs about 4 perennial [2]. The current wheat powdery mildew prevention and control agents are mainly triazoles, pyrimidines, benzimidazoles, methoxy acrylates and thiocarbamates and so on. However, rapid variation of wheat powdery mildew bacteria, rapid propagation, and single long-term use of drugs, resulting in wheat powdery mildew easily
