Aqueous extracts from leaves of 30 higher plants, collected from different localities, were screened in vitro for antibacterial activity against different pathovars of the phytopathogenic bacterium, Xanthomonas campestris. Eight plant species showed antibacterial activity, based on the zone of inhibition in a diffusion assay. Significant antibacterial activity was observed in the aqueous extracts of Prosopis juliflora, Oxalis corniculata and Lawsonia inermis. The susceptibility of different pathovars of X. campestris to these plant extracts varied. The antibacterial activity of extracts of a few plants was comparable with that of the synthetic antibiotics, bacterimycin and streptocycline. The study indicates the potential of these plant extracts in the management of diseases caused by X. campestris in several important crop plants.
