摘　　要：研究了微生物源农药申嗪霉素对水稻纹枯病的作用方式、药效及对水稻产量的影响。结果表明:申嗪霉素防治水稻纹枯病的作用方式主要是保护和防止病菌的侵入,药剂不能在水稻植株体内上下传导;该药剂与11种稻田常用杀虫剂和杀菌剂混合使用后均不影响其药效。申嗪霉素(有效用量15 g/hm^2)与井冈霉素(75 g/hm^2)和噻呋酰胺(72 g/hm^2)防治水稻纹枯病的效果和防治后水稻理论产量之间的差异均不显著。The action mode,control efficacy and impact on rice yield of microbial fungicide Shenqinmycin （phenazino-1-carboxylic acid）were studied.The results showed that the action mode of Shenqinmycin against rice sheath blight（Rhizoctonia solani）was to protect rice plants and prevent the intrusion of the pathogenic fungi. The fungicide could not conduct up and down in rice plants and and there were no impact on the control efficacy after it combined with 11 kinds of paddy common pesticides and fungicides respectively.There were no significant difference of the control efficacy against rice sheath blight and rice theoretical yield between Shenqinmycin（valid dose：15 g/hm2 ）and Jinggangmycin（75 g/hm2 ）,thifluzamide（72 g/hm2 ）respectively.
