Substituted sulfonylureas of the formula I <IMAGE> I where the substituents and indices have the following meanings: x is oxygen or sulfur; z is nitrogen or methine (=CH-); R1 is halogen or substituted or unsubstituted C1-C4-alkoxycarbonyl or C1-C3-alkoxy, or a radical -CONR6R7, where R6 is hydrogen, C1-C8-alkyl or C1-C6-alkoxy and R7 is hydrogen or C1-C8-alkyl; R2 is halogen or substituted or unsubstituted C1-C4-alkoxy or C1-C4-alkyl; R3 is C1-C4-alkyl, C1-C4-alkylthio, C1-C4-haloalkyl, C1-C4-haloalkoxy, C1-C4-haloalkylthio, halogen, cyano, nitro, amino, mono-C1-C4-alkylamino, di-C1-C4-alkylamino, C2-C6-alkenyl, C1-C4-alkoxycarbonyl, C1-C4-alkanoyl or benzyl; a 5- or 6-membered saturated heterocycle which is attached by its nitrogen atom and which, besides methylene and a nitrogen, may also contain an oxygen or a sulfur atom; or, bonded to adjacent ring positions, -OCRR'O-, where R and R' are each hydrogen or C1-C4-alkyl; R4 is hydrogen or C1-C4-alkyl; R5 is halogen C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkylthio or C1-C4-haloalkyl; m is from 0 to 3 or, when R3 is halogen, from 0 to 5, differences among the R3 radicals being possible when m is 2 or 3; and n is from 0 to 2, a difference between the R5 radicals being possible when n is 2; and environmentally acceptable salts thereof, processes for their manufacture, and their use as herbicidal agents.
