The present invention rlates to a novel 2-aminothiazolecarboxamide derivative represented by the following general formula (I) : in which R1 and R2independently of one another represent hydrogen, (C1-C5)alkyl, (C1-C5)haloalkyl, (C3-C6)alkenyl, (C3-C6)alkynyl, (C3-C6)cycloalkyl, or phenyl or benzyl, each of which can be substituted with halogen, (C1-C3)alkyl or nitro; R3represents (C1-C3)alkyl or (C1-C3)haloalkyl; R4represents 2-thienyl, 3-thienyl, 2-furyl, 3-furyl, phenyl, or phenyl or benzyl, each of which can be substituted with halogen, (C1-C6)alkyl or nitro; R5represents cyano or thiocarbamoyl; and R6represents (C1-C6)alkyl, (C3-C6)alkenyl, (C3-C6)cycloalkyl, or phenyl or benzyl, each of which can be substituted with halogen, (C1-C3)alkyl or nitro, which is a fungicidal agent useful for controlling phytopathogenic organisms. In addition, the present invention also relates to a process for preparing the novel 2-aminothiazolecarboxamide derivative of formula (I) and use of the compound of formula (I) as an agent for controlling phytopathogenic organisms.
