A series of 3-(((3-bromo-1-(3-chloropyridin-2-yl) -1H-pyrazol-5-yl) methylene) amino) substituted-benzo[d] [1,2,3]-triazin-4(3H) -ones were synthesized successfully with ethyl N-pyridylpyrazole carboxylate and substituted aminobenzoic acids as starting materials, via multi-step reactions of reduction, oxidation, nucleophilic addition, condensation and diazotization. The preliminary bioassay tests indicated that most of these compounds have certain insecticidal activities, among which one compound showed a mortality rate of 70% towards Mythimna separata Walker at the test concentration of 200 mg·L-1, some compounds exhibited favorable fungicidal activities at 50 mg·L-1, particularly two compounds which possessed 92.3% growth inhibitory rate against Physalospora piricola, could be used as new fungicidal leading structures for further investigations on this type of compounds.

Key words: N-pyridylpyrazole derivatives, benzotriazinone, insecticidal activity, fungicidal activity, structure-activity relationship
