HYDRAZONE DERIVATIVE OR ITS SALT EFFECTIVE IN CONTROLLING PEST

PROBLEM TO BE SOLVED: To provide a novel hydrazone derivative useful for controlling pests or its salt or an intermediate therefor and to provide a method for producing the hydrazone derivative or its salt. SOLUTION: The hydrazone derivative is represented by formula [I] where A, B and C are each, e.g. a hydrogen atom, a hydroxy group, a halogen atom, an alkoxy group, a trifluoromethylsulfonyloxy group, an alkyl group, an alkylthioalkyl group, an arylthioalkyl group, a nitro group, a cyano group or the like; R1and R2are each, e.g.a hydrogen atom, an alkyl group, an alkenyl group, an alkylcarbonyl group, an alkoxycarbonyl group, an alkylaminocarbonyl group or the like; and l, m and n are each, e.g. an integer of 1-5.
