Abstract
The bacterial blight of pomegranate caused by Xanthomonas axonopodispv. Punicae has become a conceivably dangerous infection. Though, the chemical management is efficient, their hazardous effects restrict them for their usage. In this context use of different parts of Prosopis juliflora extract along with antibiotics has become the alternative strategy for management of disease. Detection of secondary metabolites from different parts of the P. juliflorausing specific test indicated the presence of various secondary metabolites. However, leaf extract exhibited high concentration metabolites compared to green pod, yellow pod and inflorescence. Management of this disease utilizing plant extracts is an eco-friendly approach. Alkaloid rich fractions obtained from the different parts of Prosopis juliflora in combination with bactericides were found compatible. Leaf ARF with streptocycline @ 500 ppm showed maximum inhibition of 40.66 mm. Wherein combination with copper hydroxide @ 0.25% ppm and 2-bromo-2-nitro propane-1,3-diol @ 500 ppm showed inhibition of 25.00 mm and 36.98 mm whereas copper oxychloride @ 0.3% showed inhibition of 28.19 mm. These fundings can be used as an effective, eco friendly management strategy against the disease and a feasible solution for antibiotic resistance.
