본 발명은 식물병원균에 대하여 방제효과를 갖는 신규한 바실러스 서브틸리스 균주, 이를 포함하는 식물병원균 방제용 조성물, 및 이를 이용한 식물병원균 방제 방법에 관한 것이다.The present invention relates to a novel Bacillus subtilis strain having a control effect against phytopathogens, a composition for controlling phytopathogens comprising the same, and a method for controlling phytopathogens using the same.

식물의 병해충 방제에는 친환경적인 기술이 보급되도록 추진되고 있는데, 생물농약은 그 동안 경제성과 제제의 제조방법 및 사용 방법상의 문제 등으로 인해 대규모로 생산되지는 못하였다. 최근 식물병의 생물학적 방제 연구가 활기를 띠어 미생물 제제의 실용화 가능성으로 외국에서는 길항 진균과 세균을 이용한 미생물 농약에 대하여 많은 개발이 이루어지고 있다(Cook and Baker, 1983; Kim 등, 1990; Dandurand 등, 2000; Jack and Robert, 1998; Jack and Robert, 2001). 예컨대, 균핵병의 생물학적 방제 인자로서 Coniothyrium minitans (Whipps and Gerlagh, 1992), Serratia plymuthica (Merav 등, 2003), Ulocladium atrum(Li 등, 2003), Pseudomonas fluorescens(Pedras 등, 2003), Bacillus megaterium N4 (이재필 등, 2002), Nostoc strain ATCC 53789(Biondi 등, 2004) 등이 보고된 바 있다.Environmentally friendly technologies are being promoted to control pests of plants. Biopesticides have not been produced on a large scale due to economic problems and problems in the preparation and use of preparations. Recently, research on biological control of plant diseases has been encouraging, and as a result, the development of microbial pesticides using antagonistic fungi and bacteria has been developed in foreign countries (Cook and Baker, 1983; Kim et al., 1990; Dandurand et al. 2000; Jack and Robert, 1998; Jack and Robert, 2001). For example, Coniothyrium minitans (Whipps and Gerlagh, 1992), Serratia plymuthica (Merav et al., 2003), Ulocladium atrum (Li et al., 2003), Pseudomonas fluorescens (Pedras et al., 2003), Bacillus megaterium N4 (Refill) Et al., 2002), and Nostoc strain ATCC 53789 (Biondi et al., 2004).

현재 전세계 생물농약시장은 7000 억원 정도로 소규모이지만 매년 12%정도의 고속성장을 지속하고 있으며, 특히 미생물농약 분야는 년간 15 내지 20%의 고속성장을 지속할 것이라고 예측하고 있다(농경과원예사, 2001; Steve, L, 1999; Knight 등, 1997).At present, the global biopesticide market is small at about 700 billion won, but it continues to grow at a rapid rate of 12% annually, especially in the microbial pesticide sector. Steve, L, 1999; Knight et al., 1997).

따라서, 친환경적이고 인축에게 무해하면서 보다 다양한 식물병원균에 대하여 방제 활성을 갖는 생물학적 방제제의 개발이 요구된다.Therefore, there is a need for the development of biological control agents that are environmentally friendly, harmless to humans, and have a control activity against various phytopathogens.
