不同除草剂对烟草大田杂草防除研究初报

Control of Weeds in Tobacco Fields by Herbicides

摘要: 采用除草剂敌草胺、F6285、除芽通对烟草大田杂草防除进行了研究。结果表明,供试的3种除草剂均具有较好的控草效果。其中敌草胺在施药后30d、60d对杂草的防效为72.0%、57.4%,且对烟株生长抑制作用较小。F6285施药后30d、60d对杂草防效均为100%,但对后茬物有一定影响。除芽通虽对杂草具有较好的防效,但对烟株生长抑制作用较强。

Abstract: Effects of control weeds in tobacco fields by herbicides including Pendimethalin, Napropamide, F6285 were studied.The results showed that the weeds in tobacco fields were controlled well by these herbicides separately.The control effects of Napropamide on weeds in 30 days and 60 days after transplanting were 72.0%and 57.4% respectively, and no negative effect on growth and development of tobacco plants.That of F6258 was 100%, but it had negative effect on succeeding crops.The control effect of Pendimethalin was high, but it could inhibit growth of tobacco plants.
