Patent ID: 7612017

Claim:
A herbicidal composition comprising an effective amount of an active compound combination comprising (a) 4-amino-6-(1,1-dimethylethyl)-3-methylthio-1,2,4-triazin-5(4H)-one (metribuzin), and (b) 2-(2-chloro-4-methylsulphonylbenzoyl)-1,3-cyclohexanedione (sulcotrione), wherein from 0.02 to 50 parts by weight of component (b) are present per part by weight of component (a), and (c) optionally, a compound that improves crop plant compatibility selected from the compounds 1-methylhexyl 5-chloroquinoxalin-8-oxyacetate (cloquintocet-mexyl), α-(cyanomethoximino)phenylacetonitrile (cyometrinil), 2,4-dichloro-phenoxyacetic acid (2,4-D), 4,6-dichloro-2-phenylpyrimidine (fenclorim), ethyl 1-(2,4-dichlorophenyl)-5-trichloromethyl-1H-1,2,4-triazole-3-carboxylate (fenchlorazol-ethyl), phenylmethyl 2-chloro-4-trifluoromethylthiazole-5-carboxylate (flurazole), 4-chloro-N-(1,3-dioxolan-2-ylmethoxy)-α-trifluoro acetoxyphenoxime (fluxofenim), ethyl 4,5-dihydro-5,5-diphenyl-3-isoxazole-carboxylate (isoxadifen-ethyl), diethyl 1-(2,4-dichlorophenyl)-4,5-dihydro-5-methyl-1H-pyrazole-3,5-dicarboxylate (mefenpyr-diethyl), 2-dichloromethyl-2-methyl-1,3-dioxolane (MG-191), 1,8-naphthalic anhydride, α-(1,3-dioxolan-2-ylmethoximino)phenylacetonitrile (oxabetrinil), N-cyclopropyl-4-[[(2-methoxy-5-methylbenzoyl)amino]sulphonyl]benzamide N-[[(4-methoxyacetylamino)-phenyl]sulphonyl]-2-methoxybenzamide and N-[[(4-methylaminocarbonyl-amino)phenyl]sulphonyl]-2-methoxybenzamide, with the proviso that the sole herbicidally active ingredients of the herbicidal composition are metribuzin and sulcotrione and with the further proviso that no compound that improves crop plant compatibility other than a compound of optional component (c) can be present in the herbicidal composition.
