Abstract

Plant-derived natural bactericides and their possible applications in agriculture to control plant bacterial diseases has intensified as this approach has enormous potential to inspire and influence modern agro-chemical research. Naturally occurring and biologically active plant products such as essential oils and organic extracts could be a source of alternative classes of natural biopesticides to serve as templates for new and more effective compounds in controlling plant pathogenic micro-organisms. In the present study, the efficacy of six plants extracts from different solvent system were tested for their antibacterial activity aganist Xanthomonas oryzae pv. oryzae both in vitro and in vivo. Among these extracts, Cocculus hirsutus leaf chloroform extract exhibits significant antibacterial activity against X. oryzae pv. oryzae. Data obtained from the experiments such as minimum inhibitory concentration, effect of C. hirsutus leaf chloroform extract on the incidence of X. oryzae pv. oryzae, phytotoxicity test and effect of C. hirsutus leaf chloroform extract on seed germination and seedling vigour, along with the in vivo experiments under greenhouse conditions showed significant improvement over controls. Thus, the present study demonstrated that the C. hirsutus leaf chloroform extract posses antibacterial activity against bacterial leaf blight pathogen of rice.
