The present invention relates to an inhibitor for tobacco axillary bud growth, the inhibitor comprising one or more cell division inhibitors selected from the group consisting of pyridine-based compounds and benzamide-based compounds. This inhibitor for tobacco axillary bud growth has excellent sustainability of effect at low concentration, does not cause chemical damage and disease, and can ensure an improvement in labor productivity. An aliphatic alcohol having 6 to 20 carbon atoms is furthermore combined with the cell division inhibitors selected from pyridine-based compounds and benzamide-based compounds to thereby synergistically enhance the effect of inhibiting the emergence and growth of tobacco axillary buds.
