Abstract: Herbicides containing: A) At least one compound selected from the group comprising substituted phenylsulphonyl ureas of general formula (I) and their agriculturally acceptable salts, and B) At least one herbicidal compound selected from the group of compounds consisting of: Ba) herbicides which are selectively active against grasses in cereals selected from fenoxaprop, fenoxaprop-P, isoproturon, diclofop, clodinafop, a mixture of clodinafop and cloquintocet, chlorotoluron, methabenzthiazuron, imazmethabenz, tralkoxydim, difenzoquat, flamprop, flamprop-M and pendimethalin; Bb) herbicides which are selectively active against dicotyledons in cereals selected from mecoprop, mecoprop-P, MCPA, dichlorprop, dichlorprop-P, 2,4-D, dicamba, fluroxypyr, ioxynil, bromoxynil, bifenox, fluoroglycofen, lactofen, fomesafen, oxyfluorfen, ET 751, azoles of formula (II), F8426, diflufenican and bentazone; Bc) herbicides which are selectively active against grasses and dicotyledons in cereals selected from metribusin, metosulam, flupoxam, prosulfocarb, flutamone, amidosulfuron, metsulfuron, tribenuon, thifensulfron, triasulfron, chlorsulfron, sulfonylureas of formula (III), sulfonylureas of formula (IV), Flupyrsulfron, MON 48500 and  sulfosulfron (MON37500) and Bd) herbicides which are non-selectively active on uncultivated land or in permanent cultivation (plantations) and/or are selectively active against unwanted grasses and weeds in transgenic cultivation selected from glufosinate, glufosinate-P and glycophosate. The weight ratio of type A compounds to type B compounds is 1:2 500 to 20:1. In formula (I), R1 is alkyl, alkenyl, alkynyl or alkyl substituted 1-4 times by radicals selected from the group comprising halogen and alkoxy. In formula (II), R1 is alkyl; R2 is alkyl, alkylthio or alkoxy, each which may be optionally substituted with one or more halogen atoms; or R1 and R2 together form (CH2)m wherein m is 3 or 4; R3 is hydrogen or halogen; R4 is hydrogen or alkyl, R5 is hydrogen, nitro, cyano, alkyl, alkylthio or -NR11R12; R7 and R8 are independently selected from hydrogen and alkyl, or R7 and R8 together with the nitrogen to which they are attached form a 5 or 6 membered ring; R10 is hydrogen, alkyl optionally substituted with one or more halogen atoms; R11 and R12 are independently selected from hydrogen, alkyl, alkoxycarbonyl or together with the nitrogen to which they are attached for a 3, 5 or 6 membered ring which may optionally contain an oxygen atom. In formula (III), R1 is methyl, ethyl, n-propyl, isopropyl or allyl; R2 is COR5, COOR6, CONR8R9, CSNR10R11, SO2R14 or SO2NR15R16; R3 is COR17, COOR18, CONR19R20 or COON=CR22R23; R4 is hydrogen or alkyl; R5 is hydrogen, alkyl, haloalkyl, cyclopropyl, phenyl, benzyl or heteroaryl having 5 to 6 ring atoms, the last three groups are optionally substituted by one or more halogen atoms; R6 is alkyl, allyl, propagyl or cyclopropyl; R8 and R19 are each independently selected from hydrogen, alkyl, haloalkyl and alkoxycarbonyl; R9-R11 and R20 are independently selected from hydrogen and alkyl; R14 is alkyl; R15 and R16 are independently selected from hydrogen or alkyl; R17 is hydrogen, alkyl, haloalkyl, cycloalkyl, optionally substituted phenyl or optionally substituted heteroaryl; R18 is hydrogen, alkyl, alkenyl, alkynyl, the last three substituents optionally substituted by one or more radicals selected from halogen, alkoxy, alkylthio, NR31R32, cycloalkyl and cycloalkylalkyl; R22, R23, R31 & R32 are independently selected from hydrogen and alkyl; W is oxygen or sulfur; X is alkyl, alkoxy, haloalkyl or alkylthio; and Z is CH or N. In formula (IV), R1 is alkyl, alkenyl alkynyl or alkyl substituted with 1-4 radicals selected from the group of halogen and alkoxy.
