摘要
[目的]筛选出高效、低毒、无药害的烟田除草剂.[方法]采用小区试验研究目前烟草推荐使用的闲耕、金都尔、烟隆旺、烟舒4种芽前除草剂对烟田杂草的防除效果.[结果]异嗯草松和仲丁灵为有效成分的烟隆旺除草剂对烟田杂草的防除效果较好,药效持续时间较长;金都尔和烟舒对单子叶杂草的防治效果好于对双子叶杂草;各参试除草剂对烟株生长影响不大,未产生明显药害.检测报告显示,各处理药剂在烟叶中未出现农药残留,但在土壤中均留下一定量相对应的农药残留物.[结论]试验结果为烟叶生产中合理使用除草剂提供了参考
Abstract
[Objective] To screen a tobacco field herbicide with high efficiency,low toxicity and no phytotoxicity.[Method] Control effects of four herbicides (Xiangeng,Jinduer,Yanlongwang,Yanshu) on weeds in tobacco fields were researched by plot experiment.[Result]When clomazone and butralin were the effective components of herbicide,the control effects on weeds in tobacco fields were relatively good;and the pesticide effect lasted long.Control effects of Jinduer and Yanshu on monocotyledonous weeds were better than those on dicotyledon weeds.All the tested herbicides had little effects on the growth of tobacco plant;but a certain number of correspondent pesticide residues still remained in the soil.[Conclusion] This research provides references for the rational application of herbicides in tobacco leaves.
