Bacteriophages in the quince trees protection against the fire blight disease

The system “bacteria Erwinia amylovora — bacteriophages Erwinia amylovora” has been investigated in the quince shoots under the controlled temperature and humidity and the absence of the most inhabitants of the orchard microbiocenosis; in the quince plants under the partially controlled conditions of the experimental plot and in the commercial quince orchard under the pressure of the biotic and abiotic stressors. In all three investigated environments E. amylovora bacteriophages, used in the experiments, demonstrated ability to suppress the fire blight pathogen bacterium Erwinia amylovora growth in the quince plants tissues.
