It is mainly grown in states of Ma harashtra. Key words: Pomegranate, Xanthomonas axonopodis, Integrated disease management.Survey on bacterial blight of pomegranate Pomegrante (Punica granatum L.), so called fruit of paradise is one of the major fruit crops of arid region. 5.81 lakhs, when compared to untreated control. The disease affects all the above ground plant parts including flowers, leaves. Field application of fungicides is necessary to control pathogens, which infect the fruit during developmental stages. Hence yield increased 6.12 tons, which worth Rs. punicae is an economically important disease of pomegranate in Maharashtra. A major bacterial disease of pomegranate is bacterial blight caused by Xanthomonas axanopodis pv.
In orchard with control, the disease severity on trees was up to 38.51% with average yield levels of 2.07 tons per hectare. At present this disease is observed on leaf, stem and on fruits, and has been responsible for the removing of many orchards in south India. Punicae, considered to be a minor disease, was reported as bacterial leaf spot in the 1950s. The average yield levels were 5.27 tons/hectare in demonstration plots. Bacterial blight of pomegranate, caused by Xanthomonas axonopodis pv. The results indicated that before adopting the orchard integrated control management measures, the observed severity on the trees was up to 69%, and it was brought down to 10.15% in orchards where measures were adopted over three years. Demonstration was conducted in farmer field involving various components like selection of Ambiabahar treatment, use of antibiotics along with copper compounds and Bioagents. The disease was very severe in Mrig bahar. A survey was conducted in North Karnataka during 2008-10. Recently this disease was also observed in Rajasthan.

Bacterial blight of pomegranate, caused by Xanthomonas axonopodis pv. It is mainly grown in states of Maharashtra, Karnataka, Andhra Pradesh and Tamil Nadu. Abstract : Pomegrante (Punica granatum L.), so called "fruit of paradise" is one of the major fruit crops of arid region. From the year 2002, growers are in dire straits due to severe outbreak of bacterial blight caused by Xanthomonas axonopodis pv.
