摘　　要：探讨了15%乙·精微乳剂(乙草胺+精喹禾灵)防除大豆田杂草的试验效果。结果表明,药后30d,该药剂在1500～2100mL/hm2(制剂含量)下对大豆田主要禾本科杂草具有很好的防除效果,株防效和鲜重防效分别达95%以上,对阔叶杂草也具有良好的防除效果,鲜重防效为80.1%～82.5%,对总体杂草的防效显著,株防效和鲜重防效分别为86.1%以上,与其它处理间有显著差异。各处理对大豆品种安全,大豆增产明显。Efficacy of 15% acetochlor plus quizalofop-p-ethyl micro-emulsion for weed control in soybeans field was investigated. The field trials indicated that 15% acetochlor plus quizalofop-p-ethyl ME provided excellent control of the important grass weeds at 1500-2100 mL/ha 30 d after application, with 95% or higher reductions in plant number and fresh weight respectively. Good control was also provided against the broadleaf weeds, with 80.1-82.5% reduction in fresh weight. Overall weed control was significant, with 86.1% or higher reductions in plant number and fresh weight respectively.
