Evaluation of bacteriophages in the biocontrol of Pseudomonas syringae pv. syringae isolated from cankers on sweet cherry (Prunus avium L.) in Turkey

Abstract Background Bacterial canker and subsequent gummosis are caused by multiple pathogens lead to significant yield productivity losses in sweet cherry cultivation Turkey. This study identified that Pseudomonas syringae pathovars were responsible for bacterial on orchards using classical molecular methods evaluated the biocontrol effects of bacteriophages against P. pv. syringae. Results Pathogenic bacteria isolated from samples taken plants showing symptoms located İzmir Manisa provinces. Specific pathogenicity, phenotypic tests, simplex PCR. Bacteriophages effective strains soil contaminated with diseased an optimized isolation protocol. The activity bacteriophage isolates was tested vitro vivo. results pathogenicity tests immature fruits micropropagated plantlets revealed 10 pathogenic 44 plant canker. Conclusions Ten as . Nine different pure effective. indicated may demonstrate variable reactivity pathovars.
