Abstract:
PURPOSE: A method for biological control of plant diseases using Chaetomium globosum F0142 and chaetoviridins A and B produced by the same is provided, thereby effectively controlling plant diseases. CONSTITUTION: A method for biological control of plant diseases using Chaetomium globosum F0142(KCTC 0957BP) and chaetoviridins A and B produced by the same comprises spraying the cultured medium, mycelia or spores of Chaetomium globosum F0142, or chaetoviridins A and B isolated from the Chaetomium globosum cultured medium to plants, wherein the plant disease is rice blast disease, late blight, leaf rust or phytophthora blight. The chaetoviridins A and B are represented by the formula(1) and (2) respectively, and purified by extraction of Chaetomium globosum F0142(KCTC 0957BP) with ethyl acetate, first silica gel column chromatography, thin layer chromatography and second silica gel column chromatography, sequentially.
