Abstract

The present invention relates to novel 3,4-dimethyl-2-hydroxy-5-oxo-2,5-dihydropyrrole compounds substituted on the nitrogen atom, to processes for producing them, to their use in agriculture for combating animal and plant pests and also for regulating plant growth, and to compositions containing these novel pyrrole compounds. The novel 3,4-dimethyl-2-hydroxy-5-oxo-2,5-dihydropyrrole compounds substituted on the nitrogen atom correspond to the formula ##STR1## where A represents the hydroxyl group, a halogen atom or an O-acyl radical, and PA1 R represents an aryl radical, an aralkyl radical, or an heteroaromatic radical which has 5-6 ring members and which is bound by way of a carbon atom.
