ABSTRACT:
Novel 1-acyloxymethyl-4,5-dichloro-imidazole-2-carboxylic acid derivatives of the formula ##STR1## in which X represents trifluoromethyl, cyano or a group ##STR2## in which R.sup.1 represents an optionally substituted saturated or unsaturated aliphatic radical, R.sup.2 represents hydrogen, alkyl with 1 to 8 carbon atoms, alkenyl with up to 8 carbon atoms or the formyl group, R.sup.3 represents alkyl with 1 to 8 carbon atoms or alkenyl or alkynyl each with up to 8 carbon atoms, it being possible for each of these alkyl, alkenyl and alkynyl radicals to carry one or more substituents, or represents cycloalkyl with 5 to 7 carbon atoms in the ring which is optionally substituted by alkyl with 1 to 6 carbon atoms, or represents phenyl which may optionally carry one or more substituents, or R.sup.2 and R.sup.3 conjointly with the adjoining nitrogen atom form an optionally substituted 5- to 7-membered heterocyclic ring in which 1 to 3 ring members may be selected from oxygen, sulfur and nitrogen, and R represents alkyl with 1 to 6 carbon atoms, plant protective compositions containing the same as active ingredients together with diluents, and methods for protecting plants by applying such novel 1-acyloxymethyl-4,5-dichloro-imidazole-2-carboxylic acid derivatives to a plant or its habitat.
