The article investigates the influence of pathogenic bacteria on the functioning of the symbiotic system Rhizobium galegae - Galega oritntalis L. The understanding of all the processes that occur in the system will not only avoid complications, such as the effects caused by bacterial diseases, but will also greatly improve its functioning. After all, Galega oritntalis L. is an extremely promising crop for cultivation. Unfortunately, it still remains unpopular in the farms of Vinnytsia region of Ukraine as a whole, because of the difficulties to get a good harvest, which depends on the ability of Galega to enter into symbiosis with rhizobia. Phytopathogenic bacteria cause a significant harmful effect on Galega oritntalis L., and their pathogenic effect leads to a decrease in the yield of Galega by 32-42% of green mass and 15-30% of seeds and hinders the efficient operation of this symbiosis. In the process, we found that the major bacterial pathogen Galega is Pseudomonas syringae pv. syringae, which affects all parts of terrestrial plants, and we also defined a number of symptoms of plant injury that were caused by bacterial pathogens. Bacteriological analysis of samples of affected Galega was carried our. Strains of Pseudomonas sp. were revealed and characterized. As biochemical parameters, allocated isolates can be identified as Pseudomonas syringae or Pseudomonas savastanoi. Other potential pathogens of bacterial diseases of legumes, which can affect a Galega oritntalis L., were also noted.
