Abstract

Herbicidal and plant growth-regulating N-aryl heterocycles of the formula ##STR1## where A represents one of the groupings ##STR2## where R.sup.1 and R.sup.2 in each case independently of one another represent hydrogen, halogen, halogenoalkyl or alkyl, PA1 Y.sup.1 and Y.sup.2 in each case represent oxygen or sulphur and PA1 Z represents hydrogen, hydroxyl or chlorine, R represents in each case optionally branched alkyl, alkenyl, cycloalkyl, cycloalkenyl, cycloalkylalkyl or cycloalkenylalkyl in each case interrupted by at least one oxygen atom and in each case substituted by at least one fluorine atom, PA1 X represents hydrogen or halogen and PA1 Y represents hydrogen or halogen.
