OAK WILT TREATMENT

What is Oak Wilt?

Oak wilt is a disease that is dangerous to oak trees, especially the red oak, caused by a particular fungus called Bretziella fagacearum. You don’t have to memorize the name of the fungus to recognize symptoms of oak wilt in your trees. Most people first notice that there’s a problem when they see dead foliage at the top of their oaks. Leaves may become discolored, wilt, and fall off when they should be healthy and growing. If you suspect oak wilt, you have to act fast because oak wilt can completely kill a healthy oak tree in a matter of weeks, and oak wilt tends to spread quickly.

How Do I Know If I Have Oak Wilt?

  • Inspecting Oak Trees for Oak Wilt

    Diagnosing a tree with laboratory tests is the best way to be sure that oak wilt has taken hold of your oaks, but there are some signs that a visual inspection will help identify the fungal attack

  • Check The Tops of Oak Trees

    Oak trees display the signs of an oak wilt attack at the top of the tree first. This is especially easy to notice in the summer, when one oak tree may be full except for a bald spot at the top. It’s so noticeable in the summer because the neighboring healthy trees will have a full, green canopy, so the lone baldy will stand out. If you notice an oak tree that looks dead at the top, it deserves closer inspection.

  • Time Is Of The Essence

    Dealing with a suspected oak wilt attack, time is not on your side. The fungus can kill a huge oak in as little as a month. If you suspect oak wilt, you should seek the services of a trained arborist immediately. Saving the infected oak and preventing the spread of oak wilt to surrounding trees requires swift action. As soon as you suspect a problem, investigate it.

  • Inspect The Veins Of The Tree

    Oak trees use veins to carry nutrients from the roots throughout the tree. Because oak wilt is a disease that attacks the vascular system of oaks, preventing transport of water and nutrients, a careful inspection of the veins of a tree under the bark can reveal dark or discolored veins in a sick tree.

  • Laboratory Tests

    The only conclusive way to determine if your oak trees are being ravaged by oak wilt is to send samples to a laboratory for testing.
