<IMAGE> (I) and the salts of these compounds with amines, alkali or alkali earth metal bases or with quaternary ammonium bases have good pre- and post-emergence, selective herbicidal and growth-regulating properties. In this formula R1 and R2, independently of each other, are hydrogen or C1-C2alkyl, R3 is hydrogen, halogen, nitro, C1C4alkyl, C1-C4haloalkyl, C1-C4-alkoxy, C1-C4haloalkoxy, C1-C4-alkoxycarbonyl, C1-C4alkylthio, C1-C4alkylsulfinyl, C1-C4alkylsulfonyl or C2-C5alkoxyalkoxy or -SO2NR4R5, R4 is hydrogen, C1-C2alkoxy or C1-C4alkyl, R5 is hydrogen, methyl or ethyl, R6 and R7 are each hydrogen, methyl or ethyl, W is oxygen, sulfur, a sulfinyl and sulfonyl bridge A is a radical selected from <IMAGE> <IMAGE> <IMAGE> <IMAGE> +TR <IMAGE> in which the substituents E1, E2, X1, X2, X3, X4, X5, X6, X7, X8, Y1, Y2, Y3, Y4, Y61, Y8, Y81, Z3 and Z5 are customary organic radicals.
