| description | Attention is focused on the fact that in recent years there has been epiphytotic dieback out of many species of forest woody plants both in Ukraine and in other countries of the world, which has a dynamic character and a tendency to grow. In the deep pathology of this phenomenon, phytopathogenic bacteria, which have high reproduction energy and can penetrate the plant both from the outside and cause a pathological process as vital obligates, were left without attention. It has been established that the most common and harmful disease of common ash in Ukraine is tuberculosis. The causative agent of the disease is the phytopathogenic bacterium Pseudomonas syringae pv. savastanoi Gard. affects both trunks, branches and shoots, and inflorescences of common ash. Bacteria Pseudomonas sp., Pseudomonas fluorescens Mig., Pseudomonas syringae Van., Erwinia herbicola Eh., Xanthomonas sp. were isolated from tuberculous pathology as a concomitant myco- and microbiota and micromycetes Cladosporium cladosporiodes Fres., Ulocladium botrytis Preus., Mycelia sterilia (dark), Mycelia sterilia (orange), Fusarium heterosporum Lin., Fusarium sp., W., Cylindrocarpon didymium Har., etc. The mechanism of systemic relationships of the components of myco- and microbiota of tuberculous pathology of common ash in the regulation (self-regulation) of pathogenicity and aggressiveness of vital obligates has been investigated. Attention is focused on the prospects and expediency of using the antagonistic properties of myco- and microorganisms and biological products based on them for the prevention and protection of tree plantations from bacterial pathogens. It is shown that the pathology of common ash is a multifaceted phenomenon with interrelated processes of an infectious and non-infectious nature. The need to distinguish between the etiology and pathogenesis of this negative phenomenon is indicated, that is, not to mix the factors that lead to the weakening of ordinary ash (factors catalyzing the disease) and the factors that cause its epiphytotic dieback |
