Abstract
The invention relates to novel suylfonylureas of the formula I ##STR1## wherein R.sub.1 is hydrogen or C.sub.1 -C.sub.5 alkyl, PA1 R.sub.2 and R.sub.3, each independently of the other, are hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy, C.sub.1 -C.sub.5 alkylthio, C.sub.1 -C.sub.5 haloalkyl, halogen, C.sub.1 -C.sub.5 haloalkylthio, C.sub.1 -C.sub.4 alkylamino, C.sub.1 -C.sub.4 dialkylamino, an alkoxyalkyl group or alkoxyalkoxy group, each containing not more than 6 carbon atoms, PA1 Z is oxygen or sulfur, PA1 E is --CH.dbd. or --N.dbd., and PA1 Q is an unsubstituted or substituted 6-membered heterocyclic radical containing 2 to 3 nitrogen atoms and bound through a carbon atom, and the salts thereof. A process for the preparation of the novel compounds and the use thereof are also described. The compounds of formula I can be used in the form of agriculturally useful compositions for controlling weeds and/or for selectively influencing plant growth.
