Abstract

The compounds of the general formula (I) ##STR1## in which X denotes 0 or --SO.sub.2 --, Y denotes CH or N, R.sub.1 denotes alkyl, alkenyl or (C.sub.2 -C.sub.6)-alkinyl which are optionally substituted, R.sub.2 denotes alkyl, alkenyl, alkinyl or cyclohexyl, R.sub.3 and R.sub.4 denote H or alkyl, and R.sub.5 and R.sub.6 denote H, (substituted) alkyl, (substituted) alkoxy, halogen, alkylthio, monoalkylamino or dialkylamino, and also salts thereof, possess advantageous herbicidal properties against monocotyledonous and dicotyledonous weeds and are suitable for selective use in large-scale crops. In addition, they possess a good plant growth-regulating action.
