고추포장의 토양에서 분리한 Bacillus sp. NAAS-1 Colletotrichum acutatum에 대한 생물학적 방제 활성을 검정 하였다 이 분리균주를 일종의 작물보호제인 카밴다짐·가스가마이신 수화제와 비교하여 검정한 결과, 기준사용량 농도(50uL/mL)와 비슷한 항진균 활성을 나타냈다. 또한 생물 검정 결과, 공시 작물보호제의 기준사용량 농도(50uL/mL)에서 보다 고추 탄저병균의 발병억제효과가 높게 나타나내었다.
Bacillus sp. NAAS-1 isolated from the field of Chili pepper was tested for biocontrol activity against anthracnose pathogen of Chili pepper caused by Colletotrichum acutatum. The antifungal activity of Bacillus sp. NAAS-1 culture broth was compared with synthetic fungicide containing carbendazim (40%) and kasugamycin (3.45%). Bacillus sp. NAAS-1 showed a similar fungicidal activity against the anthracnose pathogen at the concentration of 50uL/mL in comparison to the fungicide containing carbendazim (40%) and kasugamycin (3.45%) using a cup method. Bacillus sp. NAAS-1 also exhibited its potent fungicidal activity against the anthracnose in vivo test at the concentration of 50uL/mL when compared to the fungicide containing carbendazim (40%) and kasugamycin (3.45%)
