摘　　要：于2019~2020年测定了42%二氯异噁草酮·异丙隆水分散粒剂对冬小麦田杂草的防治效果和对冬小麦的安全性,田间试验结果表明,42%二氯异噁草酮·异丙隆水分散粒剂能有效防除冬小麦田阔叶杂草播娘蒿、荠菜和禾本科杂草大穗看麦娘,对雀麦的防效较差;该混剂剂量在1260~1386g a.i./hm^(2)对杂草鲜重总防效为89.1%~90.9%,防效均高于3.6%二磺·甲碘隆水分散粒剂、二氯异噁草酮、异丙隆3个对照药剂。42%二氯异噁草酮·异丙隆水分散粒剂在冬小麦返青期用药对冬小麦安全,产量比空白对照增产13.2%~22.1%。The trials were conducted on efficacy and wheat safety of 42%Bixlozone and Isoproturon during 2019~2020 in the wheat field.The results showed that the mixed herbicides at the dosages of 1260~1386g a.i./hm^(2) could control the broad-leaf weeds and narrow-leaf weeds effectively,including Descurainia sophia,Capsella bursa-pastoris,and Alopecurus myosuroides,However,not including Bromus japonicus.The efficacy could reach 89.1%~90.9%,and it is better than efficacy of the 3.6%Mesosulfuron-methyl and Iodosulfuron-methyl,Bixlozone,Isoproturon.42%Bixlozone and Isoproturon WDG is safe to the wheat,and there are no any damage symptoms observed.The treatment of 42%Bixlozone and Isoproturon compared to no weed control treatment could increase the wheat yield about 13.2%~22.1%.
