Abstract
N-Phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas of the general 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.1 -C.sub.6 alkyl radical which is substituted by C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 alkylsulfinyl, C.sub.1 -C.sub.4 -alkylsulfonyl, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 haloalkylthio, C.sub.1 -C.sub.4 haloalkylsulfinyl or C.sub.1 -C.sub.4 haloalkylsulfonyl, or a C.sub.2 -C.sub.6 -alkenyl radical which is unsubstituted or substituted by the above substituents, or is a C.sub.2 -C.sub.6 haloalkenyl radical, PA0 E is the methine group or nitrogen, PA0 X is oxygen, sulfur, a sulfinyl or sulfonyl bridge, PA0 Z is oxygen or sulfur, PA0 m is 1 or 2, PA0 R.sub.1 is hydrogen, halogen, C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl or a radical --Y--R.sub.5, 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--…
