ABSTRACT

Citrus canker is a bacterial disease that causes lesions on the leaves ,stems and fruit of the plant. The soil environment houses many species of antagonistic microorganisms provide immunity to certain plant species against certain microbes. These antagonistic microorganisms inhibit the growth of other microorganisms including plant pathogens by antibiosis, competition and exploitation. In this study the Rhizospheric bacteria was isolated from the soil sample and identified by biochemical characterization .Xanthomonas campestris was isolated from infected plant leaves and fruit which is isolated by biochemical characterization.

Keywords: Xanthomonas campestris, Citrus Canker, Rhizospheric bacteria.
