Data about symptomatology, pathogenicity and bacteriological characteristics of Pseudomonas syringae, and PCR methods for fast and reliable detection of the pathogen are given in this paper. Pseudomonas syringae has been experimentally proved as a pathogen of pear, apple, apricot, plum, cherry, and raspberry, and pathogen strains have also been isolated from necrotic peach buds. Two pathogen varieties, syringae and morsprunorum, were found in our research in Serbia, the former being dominant on fruit trees. The most reliable method for detection of this bacteria is PCR, using BOS and REP primers. This method has also revealed significant differences among the strains originating from fruit trees in Serbia. Thus, it was proved that the population of Pseudomonas syringae in Serbia is heterogeneous, which is very important for future epidemiological studies. Control of this pathogen includes mechanical, cultural and chemical measures, but integrated approach is very important for sustainable control.
