BENZOYLPYRIDINE DERIVATIVE OR ITS SALT, FUNGICIDE CONTAINING IT AS AN ACTIVE INGREDIENT, ITS PRODUCTION PROCESS AND INTERMEDIATE FOR PRODUCING IT

摘要

The present invention relates to a fungicide containing a novel benzoylpyridine derivative or its salt.The present invention provides a fungicide containing a benzoylpyridine derivative represented by the formula (I) or its salt:wherein X is a halogen atom, a nitro group, a substitutable alkoxy group, a substitutable aryloxy group, a substitutable cycloalkoxy group, a hydroxyl group, a substitutable hydrocarbon group, a substitutable alkylthio group, a cyano group, a carboxyl group which may be esterified or amidated, or a substitutable amino group; n is 1, 2, 3 or 4; R<1 >is a substitutable alkyl group; R<2 >is a substitutable alkyl group, a 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.
