Infectious and Noninfectious Pathology of Fraxinus excelsior L.

I.N. Kulbanska

Abstract


Some research results of pathological changes of vegetative and generative organs of Fraxinus excelsior L. under the influence of pathogenic myco- and microflora, as well as harmful entomofauna, are summarised. The most common and harmful to this woody plant is shown to be such infectious disease as tuberculosis. A causal agent phytopathogenic bacteria Pseudomonas syringae pv. savastanoi (Smith 1908) affects both the trunk, branches and twigs, and also buds of Fraxinus excelsior L. There is a variety of other pathogens and pests that considerably slow ash growth and development and reduce its qualitative characteristics.
