The present invention provides herbicide compositions for foliar treatment each containing as active ingredients, a 2-chloro-4-fluoro-5-(4methyl-5-trifluoromethyl-3-pyridazinon-2-chloro-2-yl)phenyl C1-C5 non-cyclic hydrocarbyl ether and one selected from the group consisting of (RS)-2-(4-chloro-2methylphenoxy)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.
本发明提供了一种除草剂组合物,用于叶面处理,每种组合物均含有以下活性成分:2-氯-4-氟-5-(4-甲基-5-三氟甲基-3-吡啶酮-2-氯-2-基)苯基C1-C5非环烃基醚和从以下组合中选择的一种:(RS)-2-(4-氯-2-甲基苯氧基)丙酸、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]苯甲酸酯、2-氯-N-[[[(4-甲氧基-6-甲基-1,3,5-三嗪-2-基)氨基]羰基]苯磺酰]胺、乙基(R)-2-[[4-(6-氯-1,3-苯并噁唑-2-氧基)苯氧基]丙酸酯、甲基(RS)-2-[[4-(2,4-二氯苯氧基)苯氧基]丙酸甲酯、3,5-二溴-4-羟基苯甲腈、4-羟基-3,5-二碘苯甲腈、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]吡啶-3-羧酰胺;以及通过叶面处理除草草本植物的方法。本发明的组合物可用于有效控制作物土地或非作物土地上出现的各种杂草,与单独使用活性成分的情况相比,该除草剂活性具有协同增强作用,从而可以进行低剂量应用,并且除草谱扩展,从而可以选择性地控制各种杂草,特别是在小麦、大麦、燕麦或黑麦田上。
