摘要

The invention provdes carboxamide derivatives of general formula <CHEM> wherein R represents an optionally substituted alkyl, cycloalkyl, alkenyl, aryl or aralkyl group, Y is an oxygen atom, a sulphur atom, of a sulphinyl or sulphonyl group, R<1> is an optionally substituted phenyl group, n is 0 or 1, n min is 0 to 3, R<2> is a halogen. C1-4 alkyl or C1-4 alkoxy moiety, and one of X and X<1> is a nitrogen atom, the other being a nitrogen atom or a carbon atom attached to a hydrogen atom, a halogen atom, a C1-4 alkyl group or a C1-4 alkoxy group; processes for their preparation and their use as fungicides.
