To find novel pesticide lead compounds with highly active bioactivity, 32 novel 1, 2, 3-thiadiazole derivatives con-taining 1, 3, 4-thiadiazole ring were designed and synthesized according to the principle of combination of bioactive substructures. All structures were confirmed by 1H NMR, IR and HRMS. The fungicidal and insecticidal activities of these compounds were also evaluated. The bioassay results showed that some target compounds had good fungicidal activity and excellent insecticidal activities. Among them, compounds 5-3,5-20 and 5-31 showed similar insecticidal activity against Plutella xylostella L. as compared with positive control chlorfluazuron at the same condition, compounds 5-6,5-7,5-10,5-14 and 5-17 presented 100% insecticidal activity against Culex pipiens pallen at the concentration of 5 μg/mL.
