Fire blight
This bacterial infection can affect both elder and younger mountain ash tree varieties. It typically starts in the flowers and might move to other tree components.
Ash dieback fungus
This fungal disease results in bark lesions, crown dieback, and leaf loss. The tree may die as a result of it.
Ash anthracnose disease
This fungus causes leaf blotches, defoliation, and dieback of branches. As a result, the tree may become weaker and more vulnerable to diseases and other pests.
Ash yellows
A phytoplasma is the source of this illness, which can cause the tree to yellow, wilt, and become stunted. It is potentially fatal for the tree.
Verticillium wilt
This fungus can cause branches to wilt, turn yellow, and ultimately die. The tree may die as a result.
