Abstract

N-Phenylsulfonyl-N'-pyrimidinyl ureas of the formula ##STR1## 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 PA0 A is a C.sub.2 -C.sub.6 alkenyloxy, C.sub.2 -C.sub.6 haloalkenyloxy, C.sub.2 -C.sub.6 haloalkenylthio, C.sub.2 -C.sub.6 haloalkenylsulfinyl or C.sub.2 -C.sub.6 haloalkenylsulfonyl radical PA0 Z is oxygen or sulfur, PA0 m is 1 or 2, PA0 R.sub.2 is hydrogen, halogen, C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl, C.sub.1 -C.sub.4 haloalkyl, or a radical --Y--R.sub.5, --COOR.sub.6, --NO.sub.2 or --CO--NR.sub.7 --R.sub.8, PA0 R.sub.3 and R.sub.4, each independently of the other, are hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 haloalkyl, halogen or alkoxyalkyl of at most 4 carbon atoms, PA0 R.sub.5 and R.sub.6, each independently of the other, are C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl or C.sub.2 -C.sub.6 alkynyl, PA0 R.sub.7 and R.sub.8, each independently of the other, are hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl…
