Abstract Insecticidal, acaricidal and herbicidal 1-H-3-aryl- pyrrolidine-2,4-dione derivaties of the formula Image (I) in which X represents alkyl, halogen or alkoxy, Y represents hydrogen, alkyl, halogen, alkoxy or Le A 27 619 - US halogenoalkyl, Z represents alkyl, halogen or alkoxy, n represents a number from 0-3, R represents hydrogen, or represents the groups -CO-R1, -CO-O-R2 or E? in which R1 represents alkyl, alkenyl, alkoxyalkyl, alkyl- thioalkyl, polyalkoxyalkyl or cycloalkyl which can be interrupted by hetero atoms, each of these substituents being optionally substituted by halogen, or represents optionally substitu- ted phenyl, optionally substituted phenylalkyl, substituted hetaryl, substituted phenoxyalkyl or substituted hetaryloxyalkyl and R2 represents alkyl, alkenyl, alkoxyalkyl, poly- alkoxyalkyl or optionally substituted phenyl, each of these substituents being optionally substituted by halogen, A represents hydrogen, or alkyl, alkenyl, alkynyl, alkoxyalkyl, alkyl- thioalkyl or cycloalkyl which is optionally inter- rupted by hetero atoms, each of these radicals being optionally substituted by halogen, or represents aryl, arylalkyl or hetaryl each of which is option- ally substituted by halogen , alkyl , halogeno- alkyl , alkoxy or nitro, B represents hydrogen, alkyl or alkoxyalkyl, or where A and B together with the carbon atom to which they are bonded form a carbocycle and E? represents a metal ion equivalent or an ammonium ion, and the pure enantiomeric forms of compounds of the formula (I). Le A 27 619
