The invention relates to N-phenylsulfonyl-N'-pyrimidinylureas and N-phenylsulfonyl-N-triazinylureas of the general formula ##STR1## wherein Q is selected from a radical ##STR2## Z is oxygen or sulfur, E is nitrogen or .dbd.CH--, R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.3 alkoxy, and 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 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.
