Botryosphaeria corticola can be managed in high value trees, but there is no current management for forest trees. Carbendazim and thiophanate-methyl have shown to prevent infection in cork oak in Europe, where it is applied after cork has been harvested. Sanitation is the most common management technique for this disease. [13]
The disease is characterised by the trees bleeding or oozing a dark fluid from small lesions or splits in their bark. [1] Unlike chronic oak decline, acute oak decline can lead to the death of trees within 4 to 5 years of symptoms appearing. The number of trees affected is thought to number in the low thousands, with a higher number of infected ...
Phytophthora europaea is a non-papillate homothallic plant pathogen that mainly infects European oak. [1] It differs from other species of the genus (like P. fragariae) by producing oogonia with tapered bases, irregular walls and exclusively paragynous antheridia. It has also been found in the United States. [2]
Aleurodiscus oakesii is a cluster of small, gray-white, irregular cup-shaped saprotrophic fungi that grows on decaying hardwood tree bark. This fungus may also be called hophornbeam discs, [1] and it causes smooth patch disease. A. oakesii is found year round in North America, Europe, and Asia and is commonly found on oak trees.

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 ...
