PROBLEM TO BE SOLVED: To obtain a new compound providing no fear of phytotoxicity to a useful plant body, having efficient activities for controlling plant disease, and useful as an agrochemical, especially a plant disease-controlling agent. SOLUTION: This new compound is the one of formula I (HetA is a group of formula II or the like; Q is H, a halogen or a lower alkyl; HetB is a group of formula III or the like; Y is H or a lower alkyl; HetC is a group of formula IV or the like; X is a lower alkoxy, cyano or the like; n is 0-3; with the proviso that the case in which HetA is a group of formula II or the like, HetB is a group of formula III or the like, and HetC is a group of formula IV is omitted), e.g. (E)-3-(3-methyl-1,2,5-thiadiazol-4-yl)pyridylmethanone O-(2-pyridyl)methyloxime. The compound of formula I is obtained by reacting a compound of formula V [e.g. 3-(3-methyl-1,2,5-thiadiazol-4-yl)pyridinemethanone oxime] with an alkylating agent (e.g. 2-picolyl chloride) in the presence of a base such as potassium carbonate.
