Potential antagonists were screened out and evaluated in-vitro and in-vivo as bio-control agents against the bacterial wilt pathogen. All the bio-control agents tested reduced the bacterial wilt disease to various degrees. Among the bio-control agents tested, EM instant was the most effective, while the degree of disease suppression by other microbes varied with the time of application. The effects of EM-FPE and Bokashi were not different from EM instant. Among the antagonists isolated from infested soils LR 10 showed a higher potential of disease suppression. The antagonists isolated from EM sources were effective to suppress against bacterial wilt pathogen. It means that EM contains some microbes, which can suppress the disease. Application method of bio-control agent should be suitable for antagonist’s action and prior to pathogen attack.
