小麦白粉病(Wheat Powdery Mildew)是我国小麦生产上常发性病害之一[1]。小麦白粉病的防治主要采用抗病品种和化学药剂,辅之以栽培措施的综合防治技术。由于目前生产上抗病品种相对缺乏,药剂防治成为我国小麦白粉病防治的主要措施之一[2]。自20世纪80年代以来三唑类杀菌剂一直是我国防治小麦白粉病的主要药剂,由于长期、大范围、单一的使用导致小麦白粉病菌对三唑类杀菌剂的抗药性大大提高。监
Wheat Powdery Mildew is one of the most common diseases in wheat production in China [1]. The prevention and control of wheat powdery mildew mainly uses the resistant varieties and chemical agents, combined with the comprehensive prevention and control measures of cultivation measures. Due to the current relative lack of disease-resistant varieties in production, pesticide prevention and control has become one of the major measures to control wheat powdery mildew [2]. Since the 1980s, triazole fungicides have been the main agent in the control of wheat powdery mildew in China. Due to long-term, large-scale and single use, the resistance of wheat powdery mildew to triazole fungicides has been greatly increased. Supervisor
