The invention relates to new thiazole compounds of the general formula
wherein
R is an C₁-C₁₂ alkyl group or a phenyl group, which groups are unsubstituted or substituted with halogen, nitro or cyano;
R₁ is a cyano group; a formyl group; an alkylcarbonyl or alkoxycarbonyl group having 2-5 carbon atoms; or a substituted or non-substituted benzoyl group;
R₂ is a hydrogen atom; a halogen atom; an amino group; an amino group substituted with 1 or 2 substituents selected from the group consisting of C₁-C₄ alkyl, C₂-C₅ alkynyl, C₂-C₅ alkylcarbonyl and C₂-C₅ alkoxycarbonyl; an alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl group having 1-4 carbon atoms; or a substituted or non-substituted aryl, aryloxy, arylthio, arylsulphinyl or arylsulphonyl group; and
n is 1 or 2.
The new compounds show a fungicidal activity and may be used in particular against plant pathogenic seed fungi and soil fungi.
