摘　　要：为了开发更好的防除冬小麦田多花黑麦草的除草剂,在小麦主产区进行了唑啉草酯、甲基二磺隆、吡氟酰草胺、异丙隆和吡氟酰草胺·异丙隆复配除草剂防除多花黑麦草的田间试验。结果表明:55%吡氟·异丙隆悬浮剂在冬小麦田茎叶喷雾施用,可有效防除冬小麦田多花黑麦草,且防除彻底;药后45d,株防效在90%以上,鲜重防效在95%以上。综合考虑,55%吡氟·异丙隆悬浮剂可用于防除冬小麦田多花黑麦草,推荐剂量150mL/667m2。In order to develop excellent herbicides for controlling Lolium multiflorum Lamk in winter wheat field,the field test of pinoxaden,mesosulfuron-methyl,diflufenican,isoprouron and diflufenican·isoproturon against this weed was conducted.The test results showed that pyridoxine·isoproturon 55%suspension concentrate sprayed on stems and leaves of L.multiflorum Lamk.could effectively control ryegrass in winter wheat fields.At 45 days after the treatment,the control effect was more than 90%,and the fresh weight control effect was above 95%.Considering comprehensively,pyridoxine·isoproturon 55%suspension concentrate can be used to control L.multiflorum Lamk.in winter wheat field,and the recommended dose was 150 mL/667 m2.
