摘　　要：为探索氟唑菌酰羟胺及其与咪鲜胺、戊唑醇等复配使用对油菜菌核病的防治效果,开展了田间试验。结果表明:在油菜盛花初期喷施200 g/L氟唑菌酰羟胺悬浮剂750 mL/hm^(2)+25%咪鲜胺水乳剂750 mL/hm^(2)对油菜菌核病的防效最好,且油菜产量最高;200 g/L氟唑菌酰羟胺悬浮剂750 mL/hm^(2)+430 g/L戊唑醇悬浮剂300 mL/hm^(2)和200 g/L氟唑菌酰羟胺悬浮剂750 mL/hm^(2)对油菜菌核病的防效及油菜产量表现均较好。说明上述药剂可在油菜菌核病防治中推广应用。In order to explore the control effect of pydiflumetofen and its combination with prochloraz and tebuconazole against Sclerotinia rot of rape,a field experiment was carried out.The results showed that spraying 200 g/L pydiflumetofen SC 750 mL/hm^(2)+25%prochloraz EW 750 mL/hm^(2) at the early flowering stage of rape had the best control effect against Sclerotinia rot of rape,and the rape yield was the highest.The control effect and rape yield performance of 200 g/L pydiflumetofen SC 750 mL/hm^(2)+430 g/L tebuconazole SC 300 mL/hm^(2) and 200 g/L pydiflumetofen SC 750 mL/hm^(2) were also good.It showed that the above-mentioned fungicides could be widely used in the control of Sclerotinia rot of rape.
