摘　　要：采用二甲戊灵EC和氟乐灵EC两种土壤处理剂,精喹禾灵EC、高效氟吡甲禾灵EC和15%精吡氟禾草灵EC 3种茎叶处理剂对棉田主要杂草马唐进行了防除试验。结果表明,各处理对棉花没有药害,高剂量的除草剂对马唐的防效基本一致,但是低剂量的精喹禾灵防效显著地优于其它除草剂;用该5种除草剂防除棉田杂草马唐,棉花增产效果显著,同时节省人力,降低成本,从而达到节本增效的目的。Two kinds of soil treatment agents （pendimethalin EC and trefanocide EC） and three kinds of foliar-treatment a- gents （quizalofop-p-ethyl EC, Haloxyfop-P-methyl EC and Fluazifop-butyl EC） were conducted to investigated the weed control effects against Digitaria sanguinJis （L.） Scop in Cotton field. The results showed that five herbicides had no harm to cotton seedlings. The control effects of high dose agents had no obvious difference, while the control effects of lower dose quizalofop-p-ethyl were better than others, remarkably. Chemical herbicides had a significant result in a yield increase of cotton with less time,money and labour consuming.
