摘　　要：为了确定20%氟磺胺草醚乳油对夏大豆田阔叶杂草的防效,掌握最佳使用剂量,对其进行了田间药效试验。结果表明,20%氟磺胺草醚乳油150～360ga.i./hm2对大豆田阔叶杂草有明显的防除效果,茎叶喷雾处理15d对试验地杂草的株防效可达85.1%～94.4%,30d平均鲜重防效达85.6%～96.2%。A field experiment was conducted to determine the efficacy of fomesafen 20% EC against broadleaf weeds in the soybean field. The results showed that the control efficacy was 85.1%-94.4%% at 15 day after post emergence treatment with fomesafen 20% EC at the application rate of 150-360 g a.i./hm2 in the wheat field, and 85.6%-96.2% （based on weed plant fresh weight） control efficacy at 30 day after treatment.
