【摘要】 在温室条件下,以进口样品做对照,研究沈阳化工研究院40%三甲苯草酮水分散粒剂对禾本科杂草的防除效果及对小麦的安全性。结果表明:看麦娘、早熟禾对三甲苯草酮很敏感,在150ga.i./hm2剂量下防效可达90%～100%;野燕麦的敏感性次之,在150ga.i./hm2剂量下防效达85%,在300ga.i./hm2剂量下防效达95%;稗草对三甲苯草酮的敏感性最差,在300ga.i./hm2剂量下防效为60%,在600ga.i./hm2剂量下防效为90%～95%。沈阳化工研究院样品与进口样品活性和安全性基本一致。更多还原

【Abstract】 The results of greenhouse test showed that tralkoxydim 40% WG(Shenyang Research Institute of Chemical Industry) had excellent effect to Alopecurus aequalis, Poa annua and the control effects were 90-100% at 150 g a.i./ha. The Avena fatua control effects were 85 and 95% at 150, 300 g a.i./ha, respectively. Tralkoxydim 40% WG had bad effect to Echinochloa crusgalli and the control effects were 60%, 90-95% at 300, 600 g a.i./ha, respectively. The safety and control effects of tralkoxydim 40% WG(Shenyang Research Institute of Chemical Industry) was the same as import tralkoxydim.更多还原
