A novel composition contains an active agent combination of: (a) at least one sulfonyl-anilide compound of formula (I); (b) at least one herbicide selected from e.g. aclonifen, amicarbazone, amidosulfuron, amitrole, anilofos, asulam, benazolin-ethyl, benfuresate, bifenox, bispyribac-sodium, bromoxynil, desmedipham, diclofop-methyl, diflufenican, ethofumesate, ethoxysulfuron, fenoxaprop-ethyl, fenoxaprop-P-ethyl, fentrazamide, fluazifop-P-butyl, fluazolate, flucarbazone-sodium, flufenacet, flurtamone, foramsulfuron, glufosinate, glufosinate-ammonium, iodosulfuron, ioxynil, isoproturon, isoxachlortole, isoxaflutole, lactofen, linuron, mefenacet, mesosulfuron, metramiton, methabenzthiazuron, metribuzin, neburon, oxadiargyl, oxadiazon, oxaziclomefone, phenmedipham, propanil, propoxycarbazone-sodium, pyraclonil, pyraflufen-ethyl or sulcotrione; and/or (c) at least one safener selected from e.g. cloquintocet-mexyl, isoxadifen-ethyl, mefenpyr-diethyl (preferred), 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, dichlormid, furilazole or 3-dichloroacetyl-2,2,5-trimethyl-oxazolidine. [Image] n : 0-1; A : 1-6C alkylene or 2-6C alkenylene; Ar : 6-10C aryl or heterocyclyl (both optionally substituted by NO2, CN, COOH, CONH2, CSNH2, T', OT', ST', SOT', SO2T', NHT, NT2, COT, COOT, CONHT, CONT2 or SO2NT2); T : 1-4C alkyl; T' : T or 1-4C haloalkyl; R1>1-6C alkyl or 2-6C alkenyl (both optionally substituted by halo), 3-6C cycloalkyl (optionally substituted by halo or T), 6-10C aryl or 6-10C aryl-1-4C alkyl (both optionally substituted by NO2, CN, halo, T or OT), or heterocyclyl containing 5C and 1-4 N and/or 1-2 O or S (optionally substituted by NO2, CN, halo, T or OT); R2>CN, CONH2, CSNH2, T' or OT'; R3>H, CN, CONH2, CSNH2 or halo; Q : a heterocyclic group of formula (i)-(iii); R4>H, NH2 or T'; R5>COOH, CN, CONH2, CSNH2, T' or COOT'; R6>H, halo or T'; R7>H, CN or halo, or T, OT, ST, NHT or NT2 (all optionally substituted by CN, halo or OT); R8>H, or T, OT, NHT, COT or COOT (all optionally substituted by CN, halo or OT); R9>H, CN, halo, R1>1>, OR1>1>, SR1>1>, SOR1>1> or SO2R1>1>; R1>0>H, OH, NH2, R1>1> or OR1>1>; and R1>1>1-6C alkyl (optionally substituted by CN, halo or OT), 2-6C alkenyl or 2-6C alkynyl (both optionally substituted by halo), 3-6C cycloalkyl (optionally substituted by CN, halo or T) or phenyl or benzyl (both optionally substituted by NO2, CN, halo, T' or OT'). [Image] ACTIVITY : Herbicide; Antidote. In post-emergence tests in winter barley, the herbicidal rating for N-(2-cyano-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-3-yl)-phenyl)-N-(methanesulfonyl)-3-(3,4-difluorophenyl)-propionamide (Ia) (60 g/ha) was 40 %. A combination of (Ia) (60 g/ha) and mefenpyr-diethyl (50 g/ha) had a herbicide rating of 5 %. MECHANISM OF ACTION : None given.
