The present invention relates to a fungicide containing a novel benzoylpyridine derivaitive or its salt. The present invention provides a fungicide containing a benzoylpyridine derivative represented by formula (I) or its salt: wherein X is a halogen atom, a nitro group, a substitutable alkoxy group, a substitutable aryloxy group, a substitutable cyclo(alkoxy group, a hydroxyl group, a substitutable hydrocarbon group, a substitutable alkylthio group, a cyano group, a carboxyl group which may he esterified or amidated, or at substitutable amino group; n is 1, 2, 3 or 4; R
1
is a substitutable alkyl group, R
2
is a substitutable alkyl group, it substitutable alkoxy group, a substitutable aryloxy group, a substitutable cycloalkoxy group or a hydroxyl group; and m is 1, 2, 3 or 4, provided that when m is at least 2, R
2
may contain an oxygen atom to form a condensed ring.
