Objective. To study the role of phytopathogenic bacteria in the pathology of bioenergy crops. Methods. Classical microbiological, phytopathological, biochemical, statistical methods were used in the study, meteorological conditions during the years of the researches were taken into account. Results. The experimental and review article confirms the involvement of the bacteriosis pathogens Pectobacterium carotovora subsp. carоtovora (causative agent of soft bacterial rot of acorns), Lelliottia nimipressuralis (causative agent of bacterial dropsy), Lonsdalea quercina (causative agent of acorn “drip disease”), Erwinia rhapontici (causative agent of dry rot of branches and trunks) and Pseudomonas fluorescens (causative agent of cancer ulcer disease) in the weakening and massive drying of common oak trees in Ukraine. The causative agent of bacteriosis of hanging birch Betula pendula is a phytopathogenic polybiotrophic bacterium L. nimipressuralis, which also causes water dropsy of coniferous and deciduous forest woody plants. A direct dependence of the spread of tuberculosis on the proportion of ash (Fraxinus excelsior) in the structure of plantations of different age groups was established. In the region of research, tuberculosis reaches epiphytosis on sprouting trees, especially the young ones. Outbreaks of ash tuberculosis in the study area were observed in the years when the moisture availability index was the lowest. Conclusions. The results of the bacterial pathology of bioenergy woody plants (birch, ash, poplar, oak, willow) study indicate an evolutionary negative process that leads to a significant reduction in harvest or death of trees.
