Title: Comparative study of Leaf spot and Leaf blight symptoms of Xanthomonas campestris pv. parthenii on Parthenium
Abstract: 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. parthenii. No variation in physiological, biochemical and host range between both the strains of X. campestris pv. parthenii, were recorded. The disease incidence caused by leaf spot strain was 40 as compared to leaf blight strain (8.7). Leaf spot causing strain was more virulent, host specific and with fast 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.
