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 50.4percent and 53.1percent 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.

Plant activators are a novel kind of agrochemicals that could induce resistance in many plants against a broad spectrum of diseases. To date, only few plant activators have been commercialized. In order to develop novel plant activators, a series of benzo-1,2,3-thiadiazole-7-carboxylate derivatives were synthesized, and the structures were characterized by 1H NMR, IR, elemental analyses, and HRMS or MS. Their potential systemic acquired resistance as plant activators was evaluated as well. Most of them showed good activity, especially, fluoro-containing compounds 3d and 3e, which displayed excellent SAR-inducing activity against cucumber Erysiphe cichoracearum and Colletotrichum lagenarium in assay screening. Field test results illustrated that compounds 3d and 3e were more potent than the commercial plant activator, S-methyl benzo[1,2,3]thiadiazole-7-carbothioate (BTH) toward these pathogens. Further, the preparation of compound 3d is more facile than BTH with lower cost, which will be helpful for further applications in agricultural plant protection.
