水稻纹枯病在亚州、美州、非州种植水稻的国家普遍发生。我国各稻区均有分布,长江以南稻区发生更为普遍,早、中、晚稻均受危害,特别是早稻,为害更重,成为我国水稻难治病害之一。水稻纹枯病的化学防治国外已有报道,最近,杉木良雄及西德拜耳公司均报道了防治水稻纹枯病的特效杀菌剂 Monceren,但国内报道甚少。近年来,国内普遍使用井岗霉素防效显著,但长期单一地使用一种农药易产生抗药性,现防治效果已有所下降,因而,寻找新的药剂是目前国内迫切需要解决 Rice sheath blight occurs widely in countries where rice is planted in Asian, American, and non-African states. All rice areas in our country are distributed. The occurrence of rice fields in the south of the Yangtze River is more common. Early, middle and late rice are harmed, especially in early rice, causing more serious damage and becoming one of the most difficult rice diseases in our country. Chemical control of rice sheath blight has been reported abroad. Recently, Cunninghami Sugimoto and West Bayer Company all reported Monceren, a special fungicide against rice sheath blight, but few reports were reported in China. In recent years, the widespread use of Jinggangmycin control effect was significant, but the long-term single use of a pesticide prone to drug resistance, prevention and control has been reduced, therefore, to find a new agent is currently urgently needed to be resolved
