A comparative study on growth, physiological, biochemicals, host range and diseases incidence was done of new strain bacterium producing leaf spot and leaf blight producing strains of Xanthomonas campestris pv. parthen;;. No variation in physiological, biochemical and host range between both the strains of X campestris pv. parthenii, were recorded. The disease incidence caused by leafspot strain was 40% as compared to leaf blight strain (8.7%). Leafspot causing strain was more virulent, host specific and with filst multiplication rate. The leaf spot producing strain of X campestris pv. parthenii was potential to use as bio-agent to destroy Parthenium hysterophorus a noxious weed.
