Abstract N-Phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas of the general formula Image (I), and the salts of these compounds with amines, with alkali or alkaline-earth metal bases or with quaternary ammonium bases, have good pre- and post-emergence selective, herbicidal and growth-regulating properties. The symbols in this formula are as follows: A is a C3-C6-alkynyl group, 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 or C2-C5-alkenyl or a group -Y-R5, R2 is hydrogen, halogen, C1-C5-alkyl, C2-C5-alkenyl or C1-C4-haloalkyl, or a group -Y-R5, -COOR6, -NO2 or -CO-NR7-R8, R3 and R4 independently of one another are each hydrogen, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4- haloalkyl, C1-C4-haloalkoxy, halogen or alkoxyalkyl having at most 4 carbon atoms, R5 and R6 are each C1-C5-alkyl, C2-C5-alkenyl or C2-C6-alkynyl, R7 and R8 independently of one another are each hydrogen, C1-C5-alkyl, C2-C5-alkenyl or C2-C6-alkynyl, and Y is oxygen, sulfur or a sulfinyl or sulfonyl bridge.
