摘　　要：为评价36%吡酰·二甲戊悬浮剂对旱直播稻田杂草的防除效果,2016年进行了田间药效试验。结果表明:36%吡酰·二甲戊悬浮剂对旱直播稻田稗草、莎草、鸭跖草和鳢肠有很好的防除效果,且防效随着用药量增加而提高。药后45 d,36%吡酰·二甲戊悬浮剂对总草的株防效在85%以上,鲜重防效在87%以上。In order to evaluate the control effect of diflufenican+pendimethalin 36%SC on weeds in dry direct seeding rice field,field trials were carried out in 2016,using randomized block design.The results showed that diflufenican+pendimethalin 36%SC could cotrol Echinochloa crus-galli L.Beauv,Cyperus iria,Commelina communis L.,Eclipta prostrate L.effectively in dry direct seeding rice field.The efficacies by plant number were above 85%,the efficacies by fresh weight were more than 87%on the 45th day after spraying.
