摘要
[目的]筛选薇甘菊的有效防治药剂。[方法]通过小区试验研究5种除草剂对非耕地薇甘菊的防除效果。[结果]药后45 d，5种除草剂防除非耕地薇甘菊效果均在92％以上，70％草甘·三氯吡、24％滴酸·二氯吡的防除效果达96．00％，同品种除草剂不同施药处理防除效果差异小，不同品种除草剂防除效果差异不显著。[结论]建议防除薇甘菊用药首选70％草甘·三氯吡、24％滴酸·二氯吡，88．8％草甘膦铵盐、90％草甘膦铵盐＋苄嘧磺隆、36％2甲·草甘膦作储备农药交替使用，施药剂量采用常规剂量。
Abstract
Objective] The aim was to screen out effective control herbicides on Mikania micrantha.[ Method] Through plot experiment, the controlling effects of 5 herbicides on non-farming Mikania micrantha were studied.[ Result] The results showed that: the prevention effect of 5 kinds of herbicides on non-farming Mikania micrantha had reached above 92% after spraying for 45 d.Among them, 70%glyphosate triclo-pyr and 24% drop acid clopyralid could obtain an high effect about 96%.The difference of same herbicide with different spraying process was small, while the controlling effect of different varieties was not significant.[Conclusion] It is suggested that the preferred choice for preventing Mikania micrantha was 70% glyphosate triclopyr or 24% drop acid clopyralid.88.8% glyhosate ammonium, 90% glyhosate ammonium +bensulfuron-methyl and 36% dimethyl glyphosate could be used interchangeably with conventional dosage for reserve herbicides .
