Pomegranate (Punica granatum L.) commonly called a fruit of paradise, is having antioxidant property affected by a dreaded pathogen Xanthomonas axonopodis pv. punicae (Xap) causing bacterial blight. Among 10 plant extracts tested soapnut recorded highest inhibition zone of 19.75 mm at 10% and 9.5mm at 5% concentration which is followed by garlic and meswak 9.0mm and 8.0mm at 10% and 7.25mm and 7.00mm at 5% concentration respectively. Among five strains of Pseudomonas fluorescens tested, strain no. 326 (4) and 139 has recorded highest inhibition zone of 31.0mm and 30.0mm respectively, and followed by strain pf1 (27.75 mm), strain 134 (27.25 mm) and pf5 (26.50 mm). Among the eleven different strains of Pink Pigmented Facultative Methylotrophs (PPFM) tested strain no. 10L and 75L has recorded highest inhibition zone of 9.5mm and 8.0mm respectively. Among nine micronutrients CuSO4 has recorded maximum inhibition zone of 0.60mm at 0.05%, 0.75mm at 0.1% and 0.95mm at 0.2% 12.5mm at 0.5% concentrations respectively.
