Abstract

Abstract N-Phenylsulfonyl-N'-pyrimidinyl ureas of the formula <IMAGE> and the salts thereof with amines, alkali metal or alkaline earth metal bases or with quaternary ammonium bases, have good pre- and postemergence selective herbicidal and growth regulating properties. In the above formula A is a C2-C6 alkenyloxy, C2-C6 haloalkenyloxy, C2-C6 haloalkenylthio, C2-C6 haloalkenylsulfinyl or C2 -C6 haloalkenylsulfonyl radical Z is oxygen or sulfur, m is 1 or 2, R2 is hydrogen, halogen, C1-C5alkyl, C2-C5alkenyl, C1-C4haloalkyl, or a radical -Y-R5, -COOR6, -NO2 or -CO-NR7-R8, R3 and R4, each independently of the other, are hydrogen, C1-C4alkyl, C1-C4alkoxy, C1-C4alkylthio, C1-C4haloalkyl, halogen or alkoxyalkyl of at most 4 carbon atoms, R5 and R6, each independently of the other, are C1-C5alkyl, C2-C5alkenyl or C2-C6alkynyl, R7 and R8, each independently of the other, are hydrogen, C1-C5alkyl, C2-C5alkenyl or C2-C6alkynyl, and Y is oxygen, sulfur, a sulfinyl or sulfonyl bridge.
