N-Phenylsulfonyl-N'-pyrimidinyl- and -triazinyl-ureas of the general formula <IMAGE> and the salts of these compounds with amines, alkali metal or alkaline earth metal bases or quaternary ammonium bases have good pre-emergence and post-emergence selective herbicidal properties and growth-regulating properties. In this formula, A is a C1-C6-alkyl radical which is substituted by halogen, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-alkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4-halogenoalkoxy, C1-C4-halogenoalkylthio, C1-C4-halogenoalkylsulfinyl or C1-C4-halogenoalkylsulfonyl, or is a C2-C6-alkenyl radical substituted by the above radicals, E is the methine group or nitrogen, X is oxygen, sulfur or a sulfinyl or sulfonyl bridge, Z is oxygen or sulfur, m is the number one or two, R1 is hydrogen, halogen, C1-C5-alkyl, C2-C5-alkenyl or a -Y-R5 radical, R2 is hydrogen, halogen, C1-C5-alkyl, C2-C5-alkenyl, C1-C4-halogenoalkyl or a -Y-R5, -COOR6, -NO2 or -CO-NR7-R8 radical, R3 is hydrogen, C1-C4-alkyl, C1 -C4-alkoxy, C1-C4-alkylthio, C1-C4-halogenoalkyl, halogen, C1-C4-halogenoalkoxy or alkoxyalkyl having not more than 4 carbon atoms, R4 is C1-C4-halogenoalkoxy or C1-C4-halogenoalkylthio, R5 and R6 are each C1-C5-alkyl, C2-C5-alkenyl or C2-C6-alkynyl R7 and R8 independently of one another are hydrogen, C1-C5-alkyl, C2-C5-alkenyl or C2-C6-alkynyl and Y is oxygen, sulfur or a sulfinyl or sulfonyl bridge, and A can also be an unsubstituted C2-C6-alkenyl radical if X is simultaneously oxygen.
