A quick effective method was used to synthesise Ag nano particles which were characterised by UV-Vis, IR spectroscopy, TEM and SAED.The biogenic AgNPs were found to be spherical nano particles of the average size ~10 nm seen to be embedded in a matrix of phytols. Both AgNps and alcoholic extract of Ocimum tenuiflorum are known to display antibacterial activity. The deep red coloured suspension of AgNps with a pleasant aroma was diluted in double distilled water and tested for its antibacterial action against xanthomonas axonopodis pv. punicae. The disease bacterial blight that prevails on pomegranate orchards is caused by the xanthomonas axonopodis pv. punicae and causes ~ 60-80% losses in unmanaged orchards. Optimized concentrations of the Ag Nps in the plant extract suspension were foliar sprayed and were found to be effective in inhibiting the spread of the disease.
