Eutypella canker is a plant disease caused by the fungal pathogen Eutypella parasitica. This disease is capable of infecting many species of maple trees and produces a large, distinguishable canker on the main trunk of the tree. Infection and spread of the disease is accomplished with the release of ascospores from perithecia.
The fungal pathogen Cristulariella depraedans is found in Europe and North America and mostly affects trees in the genus Acer.Trees affected in Germany and Britain are primarily the sycamore (A. pseudoplatanus) and the Norway maple (A. platanoides), while in North America the most affected are A. platanoides, the red maple (), the sugar maple (A. saccharum), the silver maple (A. saccharinum ...
Maple decline is a term describing loss of vigor and dieback in forests or urban plantings of maple trees. It is not a disease or a syndrome, nor is it contagious or endemic. Instead, it is a generalized set of symptoms that may be applied to any species of tree suffering a wide range of different stressors.
Co-existing tree and plant species will gain in the void left by the affected species, but often providing different functions. Eastern hemlock, for example, is commonly replaced by black birch in the northeast—a slow-growing, shade-tolerant and deep shade producing evergreen tree, replaced by a fast-growing, open, deciduous tree. While short ...
Rhytisma acerinum can occur in many tree species, with the most commonly affected genus being Acer.The species most commonly affected by the disease are Norway maple (Acer platanoides), silver maple (Acer saccharinum), and sycamore maple (Acer pseudoplatanus).
Maple bark disease, or maple bark stripper’s disease, is an uncommon condition caused by exposure to the spores of C. corticale. [5] The spores are hyper-allergenic and cause a hypersensitivity pneumonitis. [6] [7] The disease has been found among workers in the paper industry employed to debark, cut and chip maple logs. The symptoms include ...
