Herbicide composition

The invention discloses an herbicide composition. The herbicide composition comprises the following active components: MCPA-Na, haloxyfop-R-methyl and dicamba; and the mixed mass ratio of MCPA-Na to haloxyfop-R-methyl to dicamba is 1-8: 1-4: 1-4. The herbicide composition can effectively prevent and control mulberry nursery broadleaf weeds and gramineae weeds such as ageratum conyzoides, Polygonum aviculare, polygonum, Chenopodium glaucum, goosegrass herb, crab grass, barnyard grass, broomcorn millet and deformed nutgrass flatsedge, after 30 days, the control effect can reach more than 95%, the stems and leaves are sprayed at a mulberry sapling 3 leaf period, and the broadleaf weeds, nutgrass flatsedge weeds and gramineae weeds can be effectively controlled. 本发明公开了种除草剂组合物，主要由以下活性成分制成：二甲四氯钠、高效氟吡甲禾灵和百草敌；二甲四氯钠、高效氟吡甲禾灵和百草敌混合的质量比为1-8:1-4:1-4。本发明的除草剂组合物，可以有效的防控桑苗圃阔叶杂草和禾本科杂草如，胜红蓟、萹蓄、蓼、灰绿黎、牛筋草、马唐、稗草、黍和异性莎草等药后30天防除效果达到95％以上，在桑苗3叶期茎叶喷雾，可以有效的控制苗圃中的阔叶杂草、莎草科杂草和禾本科杂草。
