为了评价几种除草剂对烟草田杂草的防除效果及对烟草的安全性,在浏阳市烟草基地开展了田间试验.结果表明,供试的除草剂对烟草安全性较好.土壤处理剂中,80％异·异丙甲乳油、50％仲灵·异松乳油、45％甲戊·异丙甲乳油这3种复配除草剂对烟草田杂草的防治效果较好,在药后30 d对杂草的株防效为89.20％～93.92％,药后60 d对杂草的株防效为83.38％～88.53％,鲜重防效为86.53％～90.36％,均要显著优于常规对照药剂960 g/L精异丙甲草胺.行间定向喷雾茎叶处理剂中,250 g/L氟磺胺草醚AS+10％精喹禾灵EC、10％乙羧氟草醚EC+10％精喹禾灵EC、200 g/L敌草快AS+10％精喹禾灵EC等3种复配除草剂的防效较好,...

In order to evaluate control efficacy of several herbicides on weed and their selectivity to tobacco,field trial was conducted in tobacco fields of Liuyang Tobacco Base.The results showed that all tested herbicides were relatively selectiver to tobacco.Among the six pre-emergence herbicides,clomazone·metolachlor 80%EC,butralin·clomazone 50%EC,pendimethalin·metolachlor 45%EC had preferable control effect.The control efficacy of pre-emergence herbicides based on plant provided 89.20%~93.92%after 30 days of application,and 83.38%~88.53%after 60...
