Bacterial ring rot is a highly infectious disease of potato caused by Clavibacter michiganensis subsp. sepedonicus (Cms). Crop
losses caused with ring rot range from 11 to 44% in different countries and significantly increases during potato storage. In
EUmember states Cms is under strict statutory control. Management of ring rot of potato is especially difficult in storage places,
where the pathogen, being in a latent form, may infect almost all tubers. Some disinfectants or fumigants are recommended
on seed potatoes and during storage. Achieving sustainable agriculture necessitate the search for safer, more specific and
environment-friendly control methods. The aim of the project is to identify the spread of potato ring rot in Georgia, isolate the
pathogen and its specific bacteriophages for their biological control. Field studies in 5 potato production regions did not reveal
ring rot disease; though there were some tubers in potato storage houses carrying Cms, which was confirmed by molecular
detection method. Several pure Cms isolates were recovered from these samples and confirmed by specific PCR they are Cms;
their cells shapes, colony morphology and biochemical tests have been studied. Collected soil and diseased potato samples
were checked on Cms Georgian and Polish isolates on phage content. Four bacteriophages were obtained. Phagosensitivity of
the isolates to phages have been studied. Phages #8 and 13 lyse almost all Georgian and Polish Cms isolates.
