摘　　要：参照农药田间药效试验准则评价了15%噁唑·二氯可分散油悬浮剂对直播稻田一年生杂草的防除效果。试验结果为15%噁唑·二氯可分散油悬浮剂使用15 d后,不同浓度供试药剂的综合防效为77.5%~99.6%;施药30 d后,综合防效均在80%以上,同时鲜重综合防效均在85%以上。相较于对照药剂,供试药剂表现出良好的防除效果且对水稻生长安全,对非靶标生物无害。建议在水稻处于2~3叶期后,杂草3~4叶期,以225~270 g a.i/hm^2(亩用制剂量100~120 mL)喷雾使用该药剂防治水稻田一年生杂草。This study aims to evaluate the field efficacy of metamifop-quinclorac 15%OD against annual weeds in direct-seeding paddy field.The field trials were conducted according to the guidelines on efficacy evaluation of pesticides.The results showed that the total control efficacy was 77.5%-99.6%at 15 d after treatment;the total control efficacy was up to over 80%and the fresh weight control efficacy was over 85%at 30 d after treatment.Compared to the two control agents,the tested pesticides showed good effects of elimination and stimulation,and were harmless to non-target organisms.It is recommended that this pesticide mixture could be applied at 225-270 g a.i./hm^2 by foliar spray during 2-3 leaf stage of rice.
