Bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. has become an increasingly serious threat for pomegranate growers of the states Andhra Pradesh, Maharastra and Karnataka State of the Indian Subcontinent. Gradually, the center … Xanthomonas axonopodis pv. The disease manifests itself on all aerial parts of the plants such as leaf, stem, and fruits. Bacterial blight has become an increasingly serious threat for pomegranate cultivation causing yield losses up to 80% under epidemic conditions. The pathogen strains were collected from predominant pomegranate growing areas of Karnataka to understand the existence of biochemical variability among the different isolates. Bacterial blight is gaining international attention through its recent spread to other major growing areas of the world such as Pakistan 7 , South Africa 8 , and Turkey 9. Severe disease outbreaks can cause 60 to 80% yield losses 5. Precise and early diagnosis of bacterial blight is crucial for active surveillance and effective management of the disease.
