Seventy-two novel 1,3,4-oxadiazole thioether derivatives containing different flexible-chain moieties were designed and synthesized. The nematicidal activities of all the title compounds were evaluated, and some compounds showed excellent nematicidal activities against citrus nematodes. The compounds 15, 16, 18, 27, 41, 42, 44, 53, and 71 had the mortality to citrus nematodes of 92.5, 93.7, 90.3, 91
设计并合成了72个含有不同柔性链部分的新型1,3,4-恶二唑硫醚衍生物。评价了所有标题化合物的杀线虫活性,并且某些化合物对柑橘线虫显示出优异的杀线虫活性。化合物15、16、18、27、41、42、44、53和71在浓度为5%时对柑橘线虫的死亡率为92.5%,93.7%,90.3%,91.5%,92.6%,92.8%,93.5%,91.3%和91.0%。 100 mg / L,优于阿维菌素对照剂(85.9%)。在测试浓度降至50 mg / L之后,化合物16、42、44、53和71的杀线虫活性仍优于阿维菌素(65.1%),死亡率分别为72.3、71.3、70.6、71.1,和73.9%。化合物16、42、44、53和71的LC50值为16.3、18.8、20.8、17.5,和14.7 mg / L,优于市售的阿维菌素阳性对照剂(24.8 mg / L)。同时,对农药样的定性和定量分析表明,化
