ABSTRACT

Melon powdery mildew, caused by Podosphaera fusca, is one of the serious diseases of melon plant in Korea. In this study, we evaluated the effect of selected antagonistic bacteria on the inhibition of mycelial growth of various plant pathogens, and control of melon powdery mildew. Based on the 16S rDNA and gyrA gene sequences, the selected antagonistic bacteria, M09, M70, and M99-1, were identified as Bacillus velezensis. These bacteria not only inhibited the mycelial growth of 47~69% in various plant pathogens, but also significantly reduced the incidence of powdery mildew. The three strains selected in this study could be used as potential biological control agents for various plant diseases as well as melon powdery mildew.
