ABSTRACT OF THE DISCLOSURE Novel 1-acyloxymethyl-4,5-dichloro-imidazole-2-carboxylic acid derivatives of the formula Image (I) in which X represents trifluoromethyl, cyano or a group Image in which R1 represents a saturated or unsaturated aliphatic radical, which can be carrying one or more substituents selected from halogen, alkoxy with 1 to 6 carbon atoms and alkylmercapto with 1 to 6 carbon atoms, R2 represents hydro- gen, alkyl with 1 to 8 carbon atoms, alkenyl with up to 8 carbon atoms or the formyl group, R3 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 selected from alkoxy with 1 to 4 carbon atoms, alkylmercapto with 1 to 4 carbon atoms, phenyl (which may optionally carry one or more substituents selected from halogen, alkyl with 1 to 4 carbon atoms, trifluoromethyl and alkoxy with 1 to 4 carbon atoms), furyl or thienyl, 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 selected from halogen, alkyl with 1 to 4 carbon atoms, alkoxy with 1 to 4 carbon atoms, alkylmercapto with 1 to 4 carbon atoms and tri- fluoromethyl or, R2 and R3 conjointly with the adjoining nitro- gen atoms form an optionally substituted 5-membered to 7-mem- bered 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 deriva- tives to a plant or its habitat.
