Background : Two major forest medicinal resources, Korean angelica (Angelica gigas Nakai) and Cnidii rhizoma (Cnidium officnale Makino) were used as medicinal herbs for long times and in these day consumed as cosmetic materials. For keep pace with a mass demand and supply, pesticides were should be sprayed for control of pests and plant diseases. However, the social concerns on well-balanced life, pesticides safety, and continuous and stable production of clean non-timber products were increased with the times. Therefore, environmental-friendly cultivation was increased before decade. This study performed for selection of effective control agents to hyphal growth of leaf spot and anthracnose in two medicinal resources.
Methods and Results : The antifungal effects of eugneol, pine needle E.O, and 7 natural product extracts (Sophora root, green tea, neem, eucalyptus, grapefruit seed, derris, and 36% rosin) were evaluated against two plant pathogens (Phoma sp., and Colletotrichum gloeosporioides). After re-loading of each 20 ㎕ natural product extracts to the PDA plate which loaded two spore dilution (106 spores/㎖) 100 ㎕, the hyphal growth control effects to pathogens were confirmed. Among 9 control agents, eugenol and pine needle E.O were the most effective, and then Sophora root, green tea, and neem. However, 4 agents (eucalyptus, 36% rosin, grapefruit seed, and derris) were not effective.
Conclusion : It confirmed that possibility as a control agents of eugenol and pine needle E.O to leaf spot (Phoma sp.) of Korean angelica and anthracnose (Colletotrichum gloeosporioides) of Cnidii rhizoma, respectively. We will be developed as commercial products safe in the forest lands
