Based on the characteristic of benzo[d][1,2,3]thiadiazole to induce the systemic acquired resistance and improve the immunity of plants, benzo[d][1,2,3]thiadiazole was introduced into 1,2,3-benzotriazin-4-one, thirty-one novel 1,2,3-benzotriazin-4-one derivatives containing benzo[d][1,2,3]thiadiazole were designed and synthesized. Nematicidal activity showed that most of the synthesized compounds exhibited great inhibitory activity in vivo against Meloidogyne incognita at 20 mg/L. Among 31 tested compounds, A2 and A3 showed an excellent nematicidal activity with the inhibition rate of 50.4% and 53.1% at the concentration of 1.0 mg/L, respectively. The influence of substituent type and position was investigated. The relationship between structure and activity was also preliminary analyzed.

根据苯并[ d ] [1,2,3]噻二唑诱导系统获得性抗性和提高植物免疫力的特点，将苯并[ d ] [1,2,3]噻二唑引入1,2,3 -合成并合成了三十一种含苯并[ d ] [1,2,3]噻二唑的新的1,2-3-苯并三嗪-4-酮衍生物。杀线虫活性表明，大多数合成的化合物在20 mg / L的浓度下均对体内根结线虫表现出极大的抑制活性。在31种测试化合物中，A2和A3在1.0 mg / L的浓度下显示出优异的杀线虫活性，抑制率分别为50.4％和53.1％。研究了取代基类型和位置的影响。还初步分析了结构与活性之间的关系。
