Abstract
In order to study cultural, morphological and phytopathogenic properties, isolates of epiphytic microorganisms were isolated from plants of the Astrakhan region with obvious signs of bacterial damage. In the course of experimental studies, 52 isolates were isolated into pure cultures. The isolates revealed the presence of such pathogenicity factors as macerating activity in relation to the tissues of potato tubers, root crops of carrots and beets, necrotic activity in relation to seedlings of white-fruited squash and phytotoxic activity in relation to white mustard seeds. It was revealed that 25 isolates have hydrolytic activity in relation to plant tissues of potatoes, carrots and beets: 13 - high, 12 medium. 10 isolates are able to cause extensive necrotic lesions of squash seedlings. Two isolates have a complex phytotoxic effect on the germination of mustard seeds and morphometric parameters of seedlings. All 25 isolates with hydrolytic activity were selected for subsequent identification. And FP17 and FP18 isolates, which have all pathogenicity factors, can be recommended for testing agrochemical and biological plant protection products.
