4 Common Tree Diseases in North America

4 Common Tree Diseases in North America


Healthy trees make beautiful additions to residential and commercial landscapes. But when a tree is afflicted by a serious disease, its health could soon deteriorate, making it more susceptible to suddenly coming down during a windstorm. If a tree on your property appears to be diseased, it'll be worth having an experienced arborist come out and take a look. At Woodpecker Tree Service, our local arborists can identify trees that are in poor health and determine whether they can be successfully treated---or if they'll need to be safely brought down. Here are four common tree diseases in the U.S.

Powdery Mildew

Powdery mildew can become a problem on a wide assortment of trees. With this disease, fungal threads grow on the leaves' surfaces, which can dry up tissue and cause it to turn brown.This can consequently cause significant leaf loss.

Apple Scab

This disease is best-known for afflicting crabapple trees. It causes lesions on the leaves, leading to defoliation. Apple scab isn't likely to kill the tree, but it does cause a significant eyesore. By applying fungicides at the time of bud break, you can keep this issue under control.

Oak Wilt

New Jersey's state tree, the red oak, is seriously threatened by oak wilt. This fungal disease commonly kills oak trees within one year by preventing the trees from properly circulating water and nutrients. White oak trees can sometimes survive this condition, but red oaks never do. One sign of this disease is that the leaf veins turn yellow, then brown. After that, leaf loss will start to occur.

Anthracnose

This disease, which is caused by a group of fungi, affects many types of trees and shrubs. Notably, it attacks dogwoods and sycamores. Disease symptoms can vary depending on the particular pathogen, as well as the type of tree that has been afflicted. Commonly, it will cause defoliation and death.
