摘　　要：50%乙草胺微乳剂于2002、2003年防除大豆田杂草结果表明,在剂量600ga.i./hm2以上时对一年生主要禾本科杂草及小粒阔叶杂草具有良好的防除效果,株防效在80%以上;55d鲜重总防效均达到85%以上。在试验剂量下对夏大豆产量无影响。Soybean weed control experiments conducted in 2003 and 2004 indicated that an acetochlor 50% microemulsion at or above 600 g a,i./ha provided good control of grass and small-seeded broadleaf weeds, with weed plant reductions greater than 80% and 55-d fresh weight reductions greater than 85%. Soybean yields were not affected at all rates tested.
