The present invention provides herbicide compositions for foliar treatment each containing as active ingredients, a 2-chloro-4-fluoro-5-(4-methyl-5-trifluoromethyl-3-pyridazinon-2-yl)phenyl C1-C5 non-cyclic hydrocarbyl ether and one selected from the group consisting of (RS)-2-(4-chloro-2-methylphenoxy)propionic acid, 2,4-dichlorophenoxyacetic acid, (4-chloro-2-methyl)phenoxyacetic acid, 2-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-amino]carbonyl]amino]sulfonyl] benzoate, 2-chloro-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]benzenesulfonamide, ethyl (R)-2-[4-(6-chloro-1,3-benzoxazol-2-yloxy)phenoxy]propanoate, methyl (RS)-2-[4-(2,4-dichlorophenoxy)phenoxy]propionate, 3,5-dibromo-4-hydroxybenzonitrile, 4-hydroxy-3,5-diiodobenzonitrile, 3-(4-isopropylphenyl)-N',N'-dimethylurea, N'-(3-chloro-4-methylphenyl)-N,N-dimethylurea and N-(2,4-difluorophenyl)-2-[3-(trifluoromethyl)phenoxy]-3-pyridinecarboxamide; and a weeding method by foliar treatment of weeds therewith.
The present compositions can be used for effective control of various weeds occurring on crop lands or non-crop lands, in which case the herbicidal activity is synergistically enhanced as compared with the cases where the active ingredients are used separately, which makes possible low-dose application, and the herbicidal spectra are expanded, so that a wide variety of weeds can be selectively controlled, particularly on wheat, barley, oat, or rye fields.
本发明提供了用于叶面处理的除草剂组合物,每种组合物都含有作为活性成分的2-氯-4-氟-5-(4-甲基-5-三氟甲基-3-哒嗪酮-2-基)苯基C1-C5非环烃基醚和选自由(RS)-2-(4-氯-2-甲基苯氧基)丙酸组成的组中的一种、2,4-二氯苯氧乙酸、(4-氯-2-甲基)苯氧乙酸、2-[[[[(4-甲氧基-6-甲基-1,3,5-三嗪-2-基)-氨基]羰基]氨基]磺酰基]苯甲酸、2-氯-N-[[(4-甲氧基-6-甲基-1,3,5-三嗪-2-基)氨基]羰基]氨基]苯磺酰胺,(R)-2-[4-(6-氯-1,3-苯并恶唑-2-基氧基)苯氧基]丙酸乙酯,(RS)-2-[4-(2,4-二氯苯氧基)苯氧基]丙酸甲酯,3、5-二溴-4-羟基苯腈、4-羟基-3,5-二碘苯腈、3-(4-异丙基苯基)-N',N'-二甲基脲、N'-(3-氯-4-甲基苯基)-N,N-二甲基脲和 N-(2,4-二氟苯基)-2-[3-(三氟甲基)苯氧基]-3-吡啶甲酰胺;以及用其对杂草进行叶面处理的除草方法。
本发明的组合物可用于有效控制作物地或非作物地中出现的各种杂草,在这种情况下,与单独使用活性成分的情况相比,除草活性得到了协同增强,这使得低剂量施用成为可能,并且除草光谱得到了扩展,从而可以选择性地控制多种杂草,特别是小麦、大麦、燕麦或黑麦田中的杂草。
