21003 THE ANTAGONISTIC MICROORGANISM BACILLUS SP. BIG21003 AND THE PREPARATION METHOD OF PELLETED SEED INCLUDING THEREOF

PURPOSE: An antagonistic microorganism Bacillus sp. BIG21003 and a preparation method of a pelleted seed including the same are provided, thereby effectively controlling the infection of Plasmodiophora brassicae in plants. CONSTITUTION: An antagonistic microorganism Bacillus sp. BIG21003(KCTC 10236BP) to soil pathogenic bacteria is provided. A pelleted seed including the antagonistic microorganism Bacillus sp. BIG21003(KCTC 10236BP) is provided. A method for preparing the pelleted seed including the antagonistic microorganism Bacillus sp. BIG21003(KCTC 10236BP) comprises the steps of: culturing Bacillus sp. BIG21003(KCTC 10236BP) to produce spores; mixing the spores with a weight increasing agent consisting of calcium carbonate, kaolin, surfactant, silica and clay to prepare the weight increasing mixture; dissolving one or more materials selected from methyl cellulose, ethyl cellulose, dextran, Arabic gum, xanthan gum, paraffin oil, gelatin, starch, polyvinyl alcohol, polyethyleneglycol and carboxymethyl cellulose in water to prepare slurry; spraying the weight increasing mixture and the slurry to seeds in a pellet making machine to produce the sphere pelleted seed; and selecting and drying the seed. 본 발명은 무사마귀병 방제에 우수한 길항효과를 나타내는 미생물 바실러스속 BIG21003과 그것을 함유한 펠릿 종자의 제조방법에 관한 것이다. 본 발명에 의해, 역병, 입고병, 시들음병 등 토양병원균과 특히 무사마귀병균에 우수한 길항효과를 나타내는 바실러스속 BIG21003이 제공된다. 또한, 발아율이 높고, 근권 정착 능력이 높으며, 토양병원균에 대한방제효과가 큰 바실러스속 BIG21003을 함유한 펠릿 종자가 제공된다. 본 발명에 의해, 농업 생산성을 높이고 환경오염을 방지하는 효과를 가져온다.
