ETIOLOGY OF COMMON ASH DISEASES IN PODOLIA, UKRAINE
Abstract
The article summarizes study results of pathological changes of vegetative and generative organs of common ash (Fraxinus excelsior L). It is shown that this important forest tree is rather susceptible not only to different systematic and functional groups of mico- and microorganisms, but also to numerous types of harmful entomofauna. Our results demonstrate that the most common and dangerous ash disease is tuberculosis. Its causative agent - Pseudomonas syringae pv. savastanoi - affects trunks, branches and shoots as well as inflorescences of common ash. There are a variety of other pathogens and pests that considerably slow ash growth and development and reduce its qualitative characteristics.
Pathogenic microflora, contagious and non-contagious pathology, harmful entomofauna, disease symptoms, ash generative organs, ash tuberculosis, pathogenesis, disease occurrence and hazard levels.
