Inonotus dryadeus is a parasitic saprobic fungus, [1] with spores entering wounds on broadleaf trees (predominantly oak, although sometimes maple, elm and chestnut). [4] The fungus is primarily a root decay fungus, rotting the below−ground parts of roots. Detection is often difficult if the conks have not developed.
Oak wilt is a devastating exotic disease, killing some trees rapidly in a single season. [7] 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 remo
A number of newly occurring and fast spreading invasive insect pests and diseases such as Polyphagous Shot Hole Borer (PSHB) (Euwallacea spp.), [21] which can vector plant pathogenic fungus Fusarium euwallaceae, [22] and Sudden Oak Death (SOD) caused by an Oomycete Phytophthora ramorum, establish the use of endotherapy as the most efficient tree protection technique in landscapes and urban ...
Oak wilt is a fungal caused by Bretziella fagacearum, is a disease originating in eastern Russia. It can slowly or quickly kill an oak tree when the tree reacts to the fungus by plugging its own cambial tissue while attempting to block the spread of the fungus. This plug prevents the cambium vascular tissue from delivering nutrients and water ...
[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 ...
In mature trees the disease is generally less damaging, but in combination with other factors such as defoliation by insects can contribute to tree decline. A study of the effects of E. alphitoides on Quercus robur found it decreased stomatal conductance by 15–30%, did not affect the leaf mass to area ratio, decreased the nitrogen content of ...
