Application of phytochemical compounds with dual functional activities against pathogens is a novel strategy to control the disease complexes. Targeting a complex disease of tobacco caused by Meloidogyne incognita and Ralstonia solanacearum, the present study identified four active compounds from stem of a medical plant Daphne acutiloba which with bioactivities against the both pathogens. At a concentration of 25 µg ml-1, daphneone 2 (1), daphneolon (2), daphnodorin A (3) and daphnodorin B (4) displayed nematicidal activities of 40.23-70.6%, and showed antibacterial circle diameters of 4.04-8.09 mm.
