Field evaluation over the seasons showed that bactrinashak, streptocycline or bacterimycin at 0.05% concentration in combination with COC 0.25% were equally effective in reducing the disease severity. However, everyone is looking for solution; this problem is resolved by synthesizing silver nanoparticles by the reduction of silver ions in aqueous solutions with the help of green synthesis method. Screening of different botanicals and bactericides by in vitro method revealed the superior efficacy of bactrinashak at 0.05% (20 mm inhibition zone) followed by streptocycline (0.05%). 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.
