This invention relates to triazole and imidazole compounds useful as fungicides, to a process for preparing them, to fungicidal compositions containing them, and to a method of combating fungal infections in plants using them. The triazole and imidazole compounds have the general formula (I): <IMAGE> (I) wherein R1 and R2, which may be the same or different, are hydrogen, alkyl, optionally substituted cycloalkyl, cycloalkylmethyl, alkenyl, heterocyclyl, aryl or aralkyl optionally substituted with halogen, nitro, alkyl, haloalkyl, alkoxy, phenyl, phenoxy, benzyl, benzyloxy, halophenyl or haloalkoxy; R3 is hydrogen, alkyl, alkenyl, alkynyl, aralkyl or acyl; R4 and R5, which may be the same or different, are hydrogen, alkyl, alkenyl or optionally substituted aryl; R6 and R7, which may be the same or different, are hydrogen, alkyl, alkenyl or optionally substituted aryl; X is oxygen or sulphur or is SO or SO2 and Az is a 1,2,4- or 1,3,4-triazole or imidazole ring; and isomers, acid addition salts and metal complexes thereof.
