Abstract
N-phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas of the general formula ##STR1## and the salts of these compounds with amines, alkali metal or alkaline-earth metal bases or with quaternary ammonium bases have good selective, pre- and post-emergence, herbicidal and growth-regulating properties. The symbols in this formula have the following meanings: PA0 A is a C.sub.3 -C.sub.6 -alkynyl group, a C.sub.1 -C.sub.6 -alkyl group which is substituted by halogen, 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 it is a C.sub.2 -C.sub.6 -alkenyl group substituted by one of the above substituents, 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, C.sub.2 -C.sub.5 -alkenyl, or a --Y--R.sub.6 group, 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,…
