摘　　要：通过田间试验验证47%氯吡·丙·异可湿性粉剂对麦田杂草的防效及对小麦的安全性。结果表明:47%氯吡·丙·异可湿性粉剂1 057.5、1 903.5 g a.i./hm2播后苗前处理后小麦的株高、茎蘖数、鲜质量、有效穗数、穗粒数、理论产量与人工除草处理无显著差异,对小麦安全,且对菵草、繁缕、荠菜等杂草防效较佳。The efficacy and selectivity of halosulfuron-methyl · pretilachlor · isoproturon 47% WP to rice stubble wheat was investigated in a field experiment.Wheat-plant height,tiller number,fresh weight,effective panicle,grain number per panicle and theoretical grain yield in plots treated with halosulfuron-methylopretilachloroisoproturon 47%WP at 1 060 and 1 900 g a.i./hm2 before crop germination to control Beckmannia syzigachne,Stellaria media and Capsella Bursapastoris did not differ from those observed in plots were weeds were manually removed indicating that the mixture is selective to wheat.
