NOVELTY - Herbicide combination comprises: (a) tefuryltrione or its salt; and (b) at least one further herbicide including e.g. amicarbazone, aminopyralid, aminocyclopyrachlor, aminocyclopyrachlor methyl, aminocyclopyrachlor potassium, cyclosulfamuron, flucetosulfuron, indaziflam, ipfencarbazone, metamifop, orthosulfamuron, penoxsulam, pinoxaden, propyrisulfuron, pyrasulfotole, pyrimisulfan, pyroxasulfone, pyroxsulam, saflufenacil, thiencarbazone and 3-chloro-N-((4,6-dimethoxypyrimidin-2-yl)carbamoyl)-1-methyl-4-(5-methyl-5,6-dihydro-1,4,2-dioxazin-3-yl)-1H-pyrazol-5-sulfonamide.    USE - The herbicide combination is useful for combating undesirable plant growth, where the combination is applied on weeds or their parts, or the cultivating area (claimed), preferably in rice crops, where: the weeds include the genus e.g. Aegilops, Apera, Avena, Brachiaria, Bromus, Cenchrus, Commelina, Cynodon, Cyperus, Dactyloctenium, Digitaria, Echinochloa, Eleocharis, Festuca, Fimbristylis, Heteranthera, Imperata, Ischaemum, Ipomoea, Leptochloa, Lolium, Monochoria, Panicum, Paspalum, Rottboellia, Sagittaria, Scirpus, Setaria, Sorghum, Emex, Erysimum, Euphorbia, Galeopsis, Kochia, Taraxacum, Thlaspi, Trifolium, Urtica, Veronica, Viola and Xanthium. The combination is useful for combating weeds in plants that are genetically or conventionally mutated. The herbicidal activity of the combination (comprising tefuryltrione (dosage of 50 g/hectare) and flucetosulfuron (dosage 2.5 g/hectare)) was tested against Leptochloa chinensis. The results showed that the combination exhibited a combating effect of 77% after 3-4 weeks.    ADVANTAGE - The herbicidal combination exhibits: superior synergistic effect than the effect of the individually used herbicides; and high tolerability in rice crops. The high synergistic effect allows for reduced application rate, higher impact strength at the reduced dosing rate, extension of application time and/or reduction in the number of applications thus resulting in economical and ecological weed control. The combination exhibits long-term action of weed control with single or few applications.    DETAILED DESCRIPTION - Herbicide combination comprises: (a) tefuryltrione or its salt; and (b) at least one further herbicide including amicarbazone, aminopyralid, aminocyclopyrachlor, aminocyclopyrachlor methyl, aminocyclopyrachlor potassium, cyclosulfamuron, flucetosulfuron, indaziflam, ipfencarbazone, metamifop, orthosulfamuron, penoxsulam, pinoxaden, propyrisulfuron, pyrasulfotole, pyrimisulfan, pyroxasulfone, pyroxsulam, saflufenacil, thiencarbazone, thiencarbazone-methyl, 3-chloro-N-((4,6-dimethoxypyrimidin-2-yl)carbamoyl)-1-methyl-4-(5-methyl-5,6-dihydro-1,4,2-dioxazin-3-yl)-1H-pyrazol-5-sulfonamide, (2S)-2-(4-((6-chloro-1,3-benzoxazol-2-yl)oxy) phenoxy)-N-(2-fluorophenyl)-N-methylpropanamide, 3-(((5-(difluoromethyl)-1-methyl-3-(trifluoromethyl)-1H-pyrazo-4-yl)methyl)sulfonyl)-5,5-dimethyl-4,5-dihydro-1,2-oxazole, N-((4,6-dimethoxypyrimidin-2-yl)carbamoyl)-6-ethyl-2-methylimidazo(1,2-b)pyridazin-3-sulfonamide, 3-((2-((2-methoxyethoxy)methyl)-6-(trifluoromethyl)pyridin-3-yl)carbonyl)bicyclo(3.2.1)octan-2,4-dione, 2-((2-((2-methoxyethoxy)methyl)-6-(trifluoromethyl)pyridin-3-yl)carbonyl)cyclohexan-1,3-dione and 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridin-2-carboxylic acid methyl ester.
