The invention relates to N-phenylsulfonyl-N'-pyrimidinylureas and N-phenylsulfonyl-N-triazinylureas of the general formula ##STR1## wherein Z is oxygen or sulfur, E is nitrogen or .dbd.CH--, R.sub.1 is hydrogen, halogen, nitro, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 alkylsulfinyl, C.sub.1 -C.sub.4 alkylsulfonyl or C.sub.2 -C.sub.5 alkoxyalkoxy, R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.3 alkoxy, R.sub.3 and R.sub.4, each independently of the other, are hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 haloalkylthio, C.sub.1 -C.sub.4 alkylthio, halogen, C.sub.2 -C.sub.5 alkoxyalkyl, C.sub.2 -C.sub.5 alkoxyalkoxy or --NR.sub.5 R.sub.6, wherein R.sub.5 and R.sub.6 are hydrogen or C.sub.1 -C.sub.4 alkyl, and A is an unsubstituted or substituted bridge of 3 or 4 atoms which contains 1 or 2 oxygen, sulfur or nitrogen atoms and, together with the linking carbon atom, forms a non-aromatic 5- or 6-membered heterocyclic ring system, with the proviso that two oxygen atoms are separated by at least one carbon atom and that oxygen and sulfur atoms are only linked to each other if the sulfur atom takes the form of the --SO-- or --SO.sub.2 -- group; and to the salts of these compounds with amines, alkali metal bases or alkaline earth metal bases or with quaternary ammonium bases. These compounds have good pre- and postemergence selective herbicidal and growth regulating properties.
