稻瘟病是由子囊菌引起的病害,是世界上各稻区的主要的病害之一,近年在我国愈演愈烈。目前仍然依靠化学药剂和种植抗病品种来控制此病害,但是由于培育抗病品种失去抗性及化学药剂抗性的产生导致稻瘟病发生面积增大。常用药剂抗药性增加及缺乏系统防治技术导致稻瘟病防治效果不佳。据研究表明,自20世纪70年代日本报道稻瘟病菌对春雷霉素产生抗药性以来,国内外 Rice blast is a disease caused by Ascomycetes, which is one of the main diseases in various rice regions in the world and intensified in our country in recent years. At present, the disease is still controlled by chemical agents and resistant cultivars, but due to the loss of resistance due to the cultivation of resistant varieties and the generation of chemical resistance, the area of ​​rice blast is increased. Commonly used drug resistance increased and the lack of systematic control technology led to poor control of rice blast. According to the research, since the 70s in Japan reported that M. grisea resistant to kasugamycin, both at home and abroad
