Dibotryon morbosum is a fungus that affects the genus Prunus. Included in this genus are multiple species of trees and shrubs, such as: Dibotryon morbosum infects are Prunus serotina (wild cherry trees), Prunus persica (peach trees), Prunus domestica (plum trees), and Prunus cerasus (sour cherry trees).

Normal, healthy trees are able to fend off infection with their natural defense mechanisms such as basal defense and hypersensitive response. [2] Furthermore, it is known that the Hypoxylon fungi already exist on the majority of trees and are only waiting for a possible infection route to be created.
Ill-health of trees can be diagnosed, and early treatment, pruning or felling to prevent the spread may result in timber stocks and amenity trees being saved. Tree owners and Arborists/arboriculturists need to be aware of the risk posed by hazardous trees. Construction projects sometimes avoidably damage trees.
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
Scientists still rely on a set of 19th century postulates to identify disease-causing organisms but more than 100 years of research shows why we need to move on.
Oak wilt is an important disease in urban areas where trees are highly valued. The disease reduces property values because of the loss of trees and is economically costly to the property owner since they or the local government must pay for tree removal. Additionally, preventing the spread of the disease to healthy trees is costly and requires ...
It can result in sudden breakage in otherwise apparently healthy trees, with visually healthy crowns. [16] This can result in hazardous trees in public settings near roadways, trails, or buildings. Therefore, the recommended treatment would be to fell trees in areas that may be hazardous and to avoid using the infected plant material as mulch.
[48] [49] The natural durability varies between tree species, geographic regions, environmental conditions, growth stage, and increases with the age. Thereby, some trees are more resistant to fungal diseases and insects and their timber lasts longer than other trees. Notably, the timber of these trees remain durable for a long-time period, even ...
