Bacterial Diseases of Energy Plants

Abstract

The results of the study of the bacterial pathology of bioenergetic woody plants (poplar, birch), which lead to a significant reduction in harvest or death are described. Various bacterial diseases of these cultures and their pathogens, symptoms of diseases and characteristics of injuries, distribution and harmfulness of pathogens are described. The characteristics of the main bacterial diseases (bacterial cancer and bacterial necrosis of the bark) and less dangerous ones (wetwood, bacterial blight, root disease and tuberculosis) are presented. The causative agent of bacterial cancer is the Xanthomonas populi bacterium (syn. Aplano-bacterium populi). As the accompanying microbiota of the causal agents of canker prevail bacteria of the genus Pseudomonas, Erwinia, Bacillus, Corynebacterium, Chromobacterium bergonzini and fungi. The causative agents of bacterial necrosis of the bark poplar are bacteria from genera Pseudomonas, Xanthomonas, Erwinia. It is showed that bacterial wetwood (dropsy) is caused by En\’inia nimipressuralis (according to the later classification the causal agent is renamed as Enterobacter nimipressuralis (according to the modern classification. - Lelliottia nimipressuralis. In addition to this pathogen from the birch trees from the wetwood symptoms was isolated bacterium Erwinia multivora Scz.-Parf. As related bacteria are involved in the pathological process identified as Pseudomonas syringae, Enterobacter hancerogenus and bacteria of genera Xanthomonas and Bacillus. Methods of protection and prevention bacterial disease with used biopreparation “bio-gel” are given. It was proved the high effectivity of new preparation in process of biologization of agro-industrial.
