Abstract of the Disclosure The present invention relates to certain new dichloromeleic acid diamide derivatives, to a process for their preparation and to their use as fungicides. The compounds can be prepared by reaction of a dichloromaleic acid halide with an amine in a diluent and in the presence of an acid-binding agent. The active compounds according to the invention have a broad spectrum of action and can be used against parasitic fungi which attack above-ground parts of plants or which attack the plants through the soil, as well as against seed- borne pathogens. Thus they exhibit a particularly good activity against Phytophthora infestans and Pyricularia oryzae.
