Abstract
N-Phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas of the general formula ##STR1## and the salts of these compounds with amines, with alkali or alkaline-earth metal bases or with quaternary ammonium bases, have good pre- and post-emergence selective, herbicidal and growth-regulating properties. The symbols in this formula are as follows: PA0 A is a C.sub.3 -C.sub.6 -alkynyl group, PA0 E is the methine group or nitrogen, PA0 X is oxygen, sulfur or a sulfinyl or sulfonyl bridge, PA0 Z is oxygen or sulfur, PA0 m is the number one or two, PA0 R.sub.1 is hydrogen, halogen, C.sub.1 -C.sub.5 -alkyl or C.sub.2 -C.sub.5 -alkenyl or a group --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 or C.sub.1 -C.sub.4 -haloalkyl, or a group --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 independently of one another are each 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, C.sub.1 -C.sub.4 -haloalkoxy, halogen or alkoxyalkyl having at most 4 carbon atoms, PA0 R.sub.5 and R.sub.6 are each C.sub.1 -C.sub.5 -alkyl, C.sub.2 -C.sub.5 -alkenyl …
