为探究吡虫啉拌种对烟蚜的防治效果及烟草生长的影响，通过漂浮育苗及田间小区试验，对比了4种不同剂量的吡虫啉拌种对烟草种子发芽情况、农艺性状及烟蚜防治效果的差异。结果表明，每千粒烟草种子与吡虫啉有效成分量为48.27μL混合拌种后会抑制种子发芽，延迟萌发时间；在烟苗猫耳期表现出对地下部生长的抑制作用，而成苗期促生长作用未达显著水平；对烟蚜虫口量有一定减退作用，最高防效为69.63%；对烟草大田期的生长具有显著的促进作用。

Effects of tobacco seed dressing with imidacloprid of 4 different doses against Myzus persicae and on tobacco growth were studied by floating seedlings and field plot experiment. Results showed that treatments of seed dressing with 48.27μL per one thousand tobacco seeds imidacloprod could inhibit seed germination and delay germination time, and inhibit underground growth during early stage, while make no significant difference to growth during seedling stage. As for the control of Myzus persicae, the treatments showed supreme control effect of 69.63%. They also showed a significantly positive effect on economical characters of tobacco in after transplant growth.
