Abstract

During survey of bacterial blight of Pomegranate (Punica granatum L.)caused by Xanthomonas axonopodis pv. Punicae, maximum disease incidence on fruit (70%) was recorded in Bagalkot district followed by Koppal (58.57%), Gadag (50%), Bijapur (48.57%) and Raichur (48.57) districts.Average per cent disease index (PDI) on fruits was observed as maximum in Bagalkot district (35%) and minimum in Bijapur and Raichr districts (24.28%). Among the plant extracts, Ocimum (tulsi) leaves, followed by neem seed oil, garlic bulb extractand Pogostemon (patchouli) leaves were found effective against the pathogen. Among the different antagonists, Bacillus subtilis and Pseudomonas fluorescens were found superior in inhibiting growth of the pathogen.
