Abstract
Abstract N-Phenylsulfonyl-N'-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 A is difluoromethyl or 1,1,2,2-tetrafluoroethyl, X is oxygen, sulfur, a sulfinyl or sulfonyl bridge, Z is oxygen or sulfur and R 3 and R 4 , each independently of the other, are hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 alkylthio, C 1 -C 4 haloalkyl, halogen or alkoxyalkyl or at most 4 carbon atoms.
