Abstract:

To prevent and control the stem base rot and develop botanical fungicide resources, the growth rate method was used to determine the inhibitory effect of 15 kinds of Chinese herbal medicine extracts, such as Eugenia aromatica, on passion fruit stem base rot pathogen Fusarium oxysporum. According to the indoor toxicity test results, the 15 kinds of Chinese herbal medicine extracts had inhibitory effect degree from high to low as: Eugenia aromatica> Rhizoma ligustici> Alpinia officinarum> Magnolia officinalis> Coptis chinensis> Aucklandia lappa> Angelica sinensis> Raphanus sativus> Scutellaria baicalensis> Asarum sieboldii> Artemisia argyi> Isatis indigotica> Stemona japonica> Polygonatum sibiricun> Kochia scoparia, among which Eugenia aromatica, Rhizoma ligustici and Alpinia officinarum extracts had the best and stable antibacterial effects. When the inhibitory concentration of the above three extracts was 20, 80 and 80 mg/mL respectively, the inhibition rate could reach 100%. The virulence regression equation analysis showed that the EC50 of Eugenia aromatica, Rhizoma ligustici and Alpinia officinarum extracts to the tested strains was 1.46, 1.66 and 1.81 mg/mL, respectively.
