Bacterium Pseudomonas syringae van Hall and its pathovars was placed on the top of the ten most important plant pathogens list due to the huge importance for the science and economics [Mansfield et al, 2012]. At present it is known about 60 pathovars of the bacterium Pseudomonas syringae van Hall. The causative agent of bacterial canker disease, bacterium Ps. syringae pv. syringae, is one of the most economically significant Ps. syringae pathovars which affects about 180 plant species. The bacterial pathogen can substantially reduce the yield of economically important cultures such as pear, apple and quince. Relatively low temperatures and high humidity are favorable for bacteria Ps. syringae pv. syringae growth [Pinheiro et al., 2019]. That is why, the phytopathogen may cause the most serious damage in spring during budding stage of plant vegetation. For to combat bacterial canker agrotechnical, chemical and biological control measures are used. Fungi of the genus Trichoderma as well as bacteria Bacillus subtilis are used as biolo-gical control agents for the bacterial canker disease. The preparation “Pentafag”, elaborated in the Republic of Belarus on the basis of five bacterial viruses strains, bacteriophages, has shown high efficacy in the disease suppressing. Bacteriophages are widely spread and can be detected in the targeted bacteria natural environment. Furthermore, bacteriophages can regulate themselves in the sites of infection, depending of the bacterial population density. Being highly specialized bacterial parasites bac-teriophages, can be applied against antibiotic resistant pathogenic bacteria or when chemical control measures are forbidden, for example, during plants bloom stage. For the moment it is known that bacteriophages from the families, Podoviridae, Myoviridae и Siphoviridae infect Ps. syringae pv. syringae bacteria [Pinheiro et al. 2019, Rabiey et al. 2020]. The aim of the study was to investigate the ability of Ps. syringae pv. syringae bacterio-phage isolate, which we detected in the quince tissues affected with bacterial canker, to inhibit bacteria Ps. syringae pv. syringae growth in the cut quince shoots. |
