Claim:
A 1,2,4-triazole compound represented by the following general formula (1): [Chemical 1] wherein R 2 represents an unsubstituted pyridyl group or a pyridyl group substituted with a cyano, lower alkyl, halogen, lower alkoxy or lower alkylthio group as a substituent, R 1 represents an unsubstituted or substituted pyridyl group which may be substituted with a halogen, cyano or phenyl group as a substituent, a pyridine-N-oxide group corresponding to these pyridyl groups, a phenyl group substituted with a cyano or nitro group or a phenyl group substituted with, in addition to a cyano or nitro group as a substituent, a substituted or unsubstituted lower alkoxy group, an N-lower alkyl-piperazino group, a lower alkylthio group, a phenylthio group, or a lower alkylamino group, provided that R 1 is not either a phenyl group substituted with only one cyano group or a phenyl group substituted with only one nitro group and provided that R 1 is not an unsubstituted pyridyl group, a pyridyl group substituted with a lower alkyl group or a pyridine-N-oxide group corresponding to these pyridyl groups in the case that R 2 is an unsubstituted pyridyl group, or a pyridyl group substituted with a lower alkyl group, and R 3 represents hydrogen or a lower alkyl group substituted with pivaloyloxy group and in each case R 3 bonds to one of the nitrogen atoms in the 1,2,4-triazole ring represented by the general formula (1), or a hydrate or a salt thereof.
