Phosphorus-containing N-phenylsulfonyl-N'-pyrimidinylureas and N-phenylsulfonyl-N'-triazinylureas of the formula <IMAGE> and the salts of these compounds with amines, alkali or alkaline earth metal bases or quaternary ammonium bases have good pre-emergence and post-emergence selective herbicidal and growth-regulating properties. In this formula, X is a group <IMAGE> Y is hydrogen, halogen, C1-C5-alkyl, trifluoromethyl, C2-C5, alkenyl, C2-C5-alkynyl, nitro, -COOR6 or -Q-R6, Z is nitrogen or the methine group, E is oxygen or sulfur, R1 is hydrogen or C1-C5-alkyl and R2 and R3 independently of one another are C1-C3-alkyl, C1-C3-alkoxy, C1-C3-halogenoalkyl, C1-C3-halogenoalkoxy, cyclopropyl, amino, methylamino or dimethylamino, and A is oxygen, sulfur, C1-C5-alkylene, C2-C5-alkenylene, C1-C5-halogenoalkylene or -NR7-(CH2)m-; -CH2-NH-(CH2)m-; -(CH2)m-NR7- or -O-(CH2)p-, -S-(CH2)p-, -(CH2)p-O- or -(CH2)p-S-, n is zero or one, G is oxygen or sulfur, R4 is C1-C5-alkoxy, C1-C5-halogenoalkoxy, C1-C5-alkylthio, C1-C5-alkyl, C1-C5-halogenoalkyl, phenyl or hydroxyl, R5 is hydrogen, C1-C5-alkoxy, C1-C5-halogenoalkoxy, C1-C5-alkylthio, C1-C5-alkyl or hydroxyl, R6 is C1-C5-alkyl, C1-C5-halogenoalkyl or C2-C6-alkoxyalkyl, Q is oxygen, sulfur, -SO- or -SO2-, R7 is hydrogen, C1-C5-alkyl, phenyl, benzyl or phenyl which is substituted by C1-C5-alkyl, halogen or nitro, m is a number from zero to three, p is a number from zero to two and r is one or two.
