Common tree diseases in Virginia
Emerald Ash Borer
EAB is an invasive beetle from Asia that targets Ash trees. The EAB feeds on the inner bark of ash trees, disrupting the tree’s ability to transport water and nutrients. Once an ash tree has been affected, there is no cure to save that tree. Trees can be treated for EAB, but it must be done before the tree is infected with the beetle.

Bacterial Wetwood/Slime Flux
Wetwood, also known as slime flux, is a very common bacterial disease that occurs in many kinds of trees.
Wetwood is caused by bacteria that enters the tree through wounds. Wetwood is normally not a serious disease. However, a tree with a chronic case of wetwood may decline in general vigor. There is no cure or preventive treatment to avoid infection and development of bacterial wetwood.

Oak Wilt
Oak wilt is a fungus that blocks water and nutrients from the roots to the crown. Symptoms vary by tree species, but generally consist of leaf discoloration, wilt, defoliation and death. Oak wilt can be managed in early stages of disease, but is highly recommended to remove the tree for sake of more oaks contracting the disease.
