The work determined the antimicrobial activity of two pseudomonad species (Pseudomonas protegens, P. aeruginosa) isolated from the rhizosphere of wild plants in the Orenburg region. It was found that the studied strains suppress the growth of the most significant phytopathogens (Agrobacterium tumefaciens, Curtobacterium flaccumfaciens, Pseudomonas syringae, Xanthomonas campestris) to varying degrees. It was found that the P. protegens 1 strain inhibits the growth of all the studied bacteria, indicating a large set of antagonism factors. It was found that P. aeruginosa strains differ in the severity of antagonism to phytopathogens. The study revealed new potential candidates for creating agents to combat bacterial pathogens in plants.
