N-Phenylsulfonyl-N'-triazinylureas of the general formula I ##STR1## and the salts of these compounds with amines, alkali metal bases or alkaline earth metal bases or with quaternary ammonium bases, have good selective herbicidal and growth regulating properties when applied pre- and postemergence. The symbols in formula I have the following meanings: R.sub.1 is hydrogen, halogen, nitro, cyano, or an alkyl, alkoxy, alkylthio, alkylsulfonyl, alkylcarbonyl, alkylcarbamoyl or alkoxycarbonyl group, each unsubstituted or substituted by halogen or alkoxy, R.sub.2 is hydrogen, halogen, alkyl, or an alkyl, alkoxy or alkylthio group, each unsubstituted or substituted by halogen or alkoxy, R.sub.3 is alkyl, haloalkyl, alkoxy or haloalkoxy, R.sub.4 is hydrogen, halogen, R.sub.3, alkylamino or dialkylamino, R.sub.5 is hydrogen, alkyl or alkoxy, and X is an alkenylamino, cycloalkylamino or cycloalkenylamino group which may be further substituted, or is a carbamoylamido or sulfonylamino group as defined in the description, or is a 5- or 6-membered saturated heterocyclic ring system which is bonded through the nitrogen atom and which may contain a further oxygen, sulfur or nitrogen atom in the ring and must contain at least one oxo group.
