The purpose of the study in this paper was to detect and identify pathogens in some dendrofloric plants in different green spaces of Craiova. The detection and identification of the attack of different phytopathogens consisted both in periodic visual observations in the experimental area on certain organs of the host plants that showed symptoms of disease, and in performing laboratory tests. Regarding the detection of certain bacterial diseases, in the monitored period, following bacteria were identified: Agrobacterium tumefaciens, Erwinia carotovora, Pseudomonas marginalis, Xanthomonas hyacinthi, Xanthomonas campestris pv. campestris, Xanthomonas hortorum pv. pelargoni. For proper identification, not only macroscopic observations, but also laboratory tests are required to certify the initial identification in the field and, where possible, a pathogenicity test on susceptible plants was performed, obtaining the reproduction of the disease in the test plants.
