摘要

A herbicidal composition contains an active agent combination of: (1) at least one aryl-substituted cyclic keto enol derivative (I), containing a pyrrolinone, furanone, thiophenone, pyrandione, cyclopentanedione or cyclohexanedione ring; and (2) at least one safener selected from e.g. cloquintocet-mexyl and fenchlorazol ethyl. A herbicidal composition contains an active agent combination of: (1) at least one aryl-substituted cyclic keto enol derivative of formula (I) (including tautomers and/or acid or base addition salts), containing a pyrrolinone, furanone, thiophenone, pyrandione, cyclopentanedione or cyclohexanedione ring; and (2) at least one safener selected from 4-dichloroacetyl-1-oxa-4-aza-spiro-(4,5)-decane, 1-dichloroacetyl-hexahydro-3,3,8a-trimethyl-pyrrolo (1,2-a)-pyrimidin-6(2H)-one, benoxacor, cloquintocet mexyl, cumyluron, cyometrinil, 2,4-D, 2,4-DB, dymron, dicamba, dimepiperate, 2,2-dichloro-N-(2-oxo-2-(2-propenylamino)-ethyl)-N-(2-propenyl)-acetamide, dichlormid, fenclorim, fenchlorazole-ethyl, flurazole, fluxofenim, furilazole, isoxadifen-ethyl, lactidiclor, MCPA, mecoprop, mefenpyr-diethyl, 2-dichloromethyl-2-methyl-1,3-dioxolan, 1,8-naphthalic anhydride, oxabetrinil, 2,2-dichloro-N-(1,3-dioxolan-2-yl-methyl)-N-(2-propenyl)-acetamide, 3-dichloroacetyl-2,2,5-trimethyl-oxazolidine, 4-(4-chloro-o-tolyl)-butyric acid, 4-(4-chloro-phenoxy)-butyric acid, diphenylmethoxyacetic acid (or its methyl or ethyl ester), methyl 1-(2-chlorophenyl)-5-phenyl-1H-pyrazole-3-carboxylate, ethyl 1-(2,4-dichlorophenyl)-5-(methyl, isopropyl, 1,1-dimethylethyl or phenyl)-1H-pyrazole-3-carboxylate, ethyl 5-(2,4-dichlorobenzyl or phenyl)-2-isoxazolidine-3-carboxylate, ethyl 5-(4-fluorophenyl)-5-phenyl-2-isoxazolidine-3-carboxylate, 5-chloro-quinolin-8-oxyacetic acid 1,3-dimethyl-1-butyl, 4-allyloxybutyl, 1-allyloxy-2-propyl, methyl, ethyl, allyl or 2-oxo-1-propyl ester, 5-chloro-quinolin-8-oxymalonic acid diethyl or diallyl ester, 4-carboxychroman-4-yl-acetic acid, 4-chlorophenoxyacetic acid, 3,3'-dimethyl-4-methoxybenzophenone, 1-bromo-4-chloromethylsulfonyl-benzene, 1-(4-(N-2-methoxybenzoylsulfamoyl)-phenyl)-3-methylurea, 1-(4-(N-2-methoxybenzoylsulfamoyl)-phenyl)-3,3-dimethylurea, 1-(4-(N-4,5-dimethylbenzoylsulfamoyl)-phenyl)-3-methylurea, 1-(4-(N-naphthylsulfamoyl)-phenyl)-3,3-dimethylurea, N-(2-methoxy-5-methylbenzoyl)-4-(cyclopropylaminocarbonyl)-benzensulfonamide, azole derivatives of formula (IIA), quinoline, derivatives of formula (IIB), alkanamides of formula R10-CO-NR11R12 (IIC) and N-(phenylsulfonyl)-benzamide compounds of formula (IID) or (IIE).
