摘　　要：[目的]确定桶混使用8.8%精喹禾灵EC与10%唑嘧磺草胺SC对甘薯田杂草的防治效果、最佳田间配比及对甘薯的安全性。[方法]采用茎叶喷雾施药一次,定期调查的方法进行田间药效试验。[结果]如田中杂草发生偏重,8.8%精喹禾灵EC和10%唑嘧磺草胺SC可按(60+30)~(90+30) g a.i./hm^(2)进行施药防治;如田中杂草发生偏轻,8.8%精喹禾灵EC和10%唑嘧磺草胺SC可按(45+22.5)~(67.5+22.5) g a.i./hm^(2)进行施药防治。[结论]桶混化学除草剂8.8%精喹禾灵EC与10%唑嘧磺草胺SC可有效防除甘薯田多种杂草,对甘薯生长无不良影响。[Aims]To confirm the weed control effect,the optimum field ratio and safety of tank mixture of quizalofop-P-ethyl 8.8%emulsifiable concentrate and flumetsulam 10%suspension concentrate in sweet potato field.[Methods]The field efficacy trial was carried out by spraying stems and leaves once and investigating regularly.[Results]When weeds occured excessively in the field,quizalofop-P-ethyl 8.8%EC and flumetsulam 10%SC could be applied at a rate of(60+30)to(90+30)g a.i/ha;When the occurrence of weeds in the field was relatively mild,quizalofop-P-ethyl 8.8%EC and flumetsulam 10%SC could be applied at a rate of(45+22.5)to(67.5+22.5)g a.i./ha.[Conclusions]Tank mixture of chemical herbicides quizalofop-P-ethyl 8.8%EC and flumetsulam 10%SC can effectively control a variety of weeds in sweet potato field,and is safe for the growth of sweet potatoes.
