0142 METHOD FOR THE BIOLOGICAL CONTROL OF PLANT DISEASES USING CHAETOMIUM GLOBOSUM F0142 AND CHAETOVIRIDINS A AND B PRODUCED BY SAME

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. 본 발명은 식물병의 생물학적 방제에 유효한 케토미움 글로보숨() F0142(KCTC 0957BP) 또는 이에 의해 생산된 화학식 1 및 2의 케토비리딘(chaetoviridin) A 및 B를 이용한 생물학적 방제 방법에 관한 것으로, 본 발명의 케토미움 글로보숨 F0142의 배양체 및 케토비리딘 A 및 B는 벼도열병, 토마토역병, 밀붉은녹병, 고추역병 등과 같은 식물병의 생물학적 방제에 효과적으로 사용될 수 있다.
