Abstract

Substituted sulfonylureas of the formula I ##STR1## where the substituents and indices have the following meanings: X is oxygen or sulfur; PA1 Z is nitrogen or methine (.dbd.CH--); PA1 R.sup.1 is halogen or substituted or unsubstituted C.sub.1 -C.sub.4 -alkoxycarbonyl or C.sub.1 -C.sub.3 -alkoxy, or a radical --CONR.sup.6 R.sup.7, where PA2 R.sup.6 is hydrogen, C hd 1-C.sub.8 -alkyl or C.sub.1 -C.sub.6 -alkoxy and PA2 R.sup.7 is hydrogen or C.sub.1 -C.sub.8 -alkyl; PA1 R.sup.2 is halogen or substituted or unsubstituted C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkyl; PA1 R.sup.3 is C.sub.1 -C.sub.4 -alkyl, C hd 1-C.sub.4 -alkylthio, C hd 1-C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -haloalkylthio, halogen, cyano, nitro, amino, mono-C.sub.1 -C.sub.4 -alkylamino, di-C.sub.1 -C.sub.4 -alkylamino, C hd 2-C.sub.6 -alkenyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.1 -C.sub.4 -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 C.sub.1 -C.su…
