二甲四氯钠与烯草酮混用对亚麻田杂草的防除效果

Weed Control Effect of Mixed MCPA-Na and Clethodim in Flax Field

在新疆伊犁进行了二甲四氯钠与烯草酮混用防除亚麻田一年生阔叶杂草和禾本科杂草的田间试验,结果表明:药后30 d,二甲四氯钠与烯草酮混用对亚麻田杂草的株防效和鲜重防效均在88%以上,明显高于二者单用时的防效,且持效期长,一次施药能控制亚麻田生育期大多数杂草,对亚麻安全,两者混用是有效控制亚麻田杂草的理想措施。

In this research, MCPA - Na mixed with clethodim was sprayed on flax for weeds con- trol, and the results shows that the control effect was above 88% after sprayed 30 days, which is significantly higher than the single herbicide. The mixed herbicides can not only control most of weeds in flax field by spraying once, but also have longer effective lasting. Moreover, it is safe for flax and can be an ideal measure to effectively control weeds in flax field.
