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 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.
本发明涉及一种新型3,4-二甲基-2-羟基-5-酮基-2,5-二氢吡咯烷化合物,其在氮原子上被取代,以及生产这些化合物的方法,它们在农业中用于对抗动植物害虫并调节植物生长,以及含有这些新型吡咯烷化合物的组合物。这些新型3,4-二甲基-2-羟基-5-酮基-2,5-二氢吡咯烷化合物在氮原子上被取代,对应于以下结构式:其中A代表羟基、卤素原子或O-酰基基团,R代表芳基、芳基烷基或具有5-6个环成员且通过碳原子连接的杂环芳基。
