PROBLEM TO BE SOLVED: To obtain a microbicide composition showing an intensified synergic effect on the infection of wide-ranging plant diseases esp. plant plague, plant downy mildew or the like by including a specific substituted thiophene derivative and a specific compound. SOLUTION: This composition is obtained by including (A) a substituted thiophene derivative e.g. N-[2-(1,3-dimethylbutyl)-3-thienyl]-5-chloro-3 trifluoromethylpyrozole-4-carboxylic acid amide) of formula I[R is e.g. a 3-12C (halogen)alkyl, a (substituted) 3-10C cycloalkyl or a 3-10C (halogeno) alkenyl, and R and NHCOAr are adjacent to each other; Ar is e.g. of formulas II to V (R1 is e.g. trifluoromethyl, methyl or a halogen; and R2 is a halogen, methyl or methoxy); however, R1 is not a halogen when Ar is e.g. of formula III or IV] and (B) a compound selected from the group consisting of an acylalanine- based compound, dimethomorph, cymoxanil and aliette.
