The entomopathogenic fungi were an important natural pathogenic of insects that has been developed as potential biological control agents for many important agricultural, forest and medical pests. Several these fungi produce a wide range of secondary metabolites with high therapeutic value as antibiotics, cytotoxic substances, insecticides, compounds that promote or inhibit growth, attractor and repellent. Therefore, this study was performed to select the antibacterial activity of liquid culture filtrates of 347 entomopathogenic fungi form Korea soils against two pathogenic bacteria including Ralstonia solanacearum and Escherichia coli using novel method which represents a quick and easily applicable tool obtaining large number of samples. As results, eight-five strains (24%) and seventy-six strains (22%) of these fungal metabolites produced anti-R. solanacearum and anti-E. coli compounds, respectively. The preferential antibacterial activity against R. solanacearum and E. coli gives evidence that these entomopathogenic fungal metabolites might be useful as an agent for bacteria control and the technique was simple to operate and allowed a large number of samples to be handled concurrently.
