Abstract The article is devoted to the isolation, description and identification of pathogens of bacterial sunflower diseases. Sunflower is one of the energy crops in Ukraine. Phytopathogenic bacteria cause damage to sunflower crops, and their pathogenic effect leads to a decrease in the yield of the mass of sunflower and seeds. A bacteriological analysis of the affected sunflower samples was carried out. The isolates were identified and characterized according to morphological, cultural, and physiological and biochemical characteristics. According to the complex of phenotypic traits, selected isolates belong to different taxonomic groups of bacteria: Pectobacterium sp., Pseudomonas sp., Xanthomonas sp., Micrococcus sp. The pathogenic properties of collection and isolated isolates, pathogens of bacterial sunflower diseases were studied. It was found that the isolates are highly aggressive towards the investigated sunflower sprouts
Key words bacterial sunflower diseases, bacteria of the genera Pectobacterium, Pseudomonas, Xanthomonas, energy crop
