Common Tree Fungus Identification and Treatment
Tree fungus diseases are a common problem, but they can be difficult to identify and treat. In this article, we’ll discuss the most common types of tree fungus diseases, their symptoms, and how to treat them.
Types of Tree Fungus Diseases
Tree fungus diseases can be classified into three main categories:
- Foliar diseases: These diseases affect the leaves of trees. Symptoms include leaf spots, powdery mildew, and shot hole fungus.
- Vascular diseases: These diseases affect the vascular system of trees, which transports water and nutrients throughout the tree. Symptoms include wilting, yellowing leaves, and stunted growth.
- Root rot diseases: These diseases attack the roots of trees, causing them to rot and die. Symptoms include yellowing leaves, wilting, and stunted growth.
Symptoms of Tree Fungus Diseases
The symptoms of tree fungus diseases can vary depending on the type of disease. However, some common symptoms include:
- Leaf spots
- Powdery mildew
- Shot hole fungus
- Wilting
- Yellowing leaves
- Stunted growth
- Dieback
How to Treat Tree Fungus Diseases
The best way to treat tree fungus diseases is to identify the type of disease and then use the appropriate treatment. Some common treatments for tree fungus diseases include:
- Foliar diseases: Foliar diseases can be treated with fungicides.
- Vascular diseases: Vascular diseases can be treated with systemic fungicides, which are absorbed by the tree and transported throughout its vascular system.
- Root rot diseases: Root rot diseases can be treated with soil drenches or injections of fungicides.
How to Prevent Tree Fungus Diseases
The best way to prevent tree fungus diseases is to keep your trees healthy. This means providing them with the right amount of water, nutrients, and sunlight. You should also avoid injuring your trees, as this can create an entry point for fungi.

- Dutch elm disease: Dutch elm disease is a vascular disease that affects elm trees. Symptoms include wilting, yellowing leaves, and leaf drop.
- Verticillium wilt: Verticillium wilt is a vascular disease that affects a wide variety of trees. Symptoms include wilting, yellowing leaves, and stunted growth.
- Shot hole fungus: Shot hole fungus is a foliar disease that affects a wide variety of trees. Symptoms include small, round holes in the leaves.
- Sooty mold: Sooty mold is a foliar disease that affects a wide variety of trees. Symptoms include a black or gray film on the leaves.

- Cercospora leaf spot: Cercospora leaf spot is a foliar disease that affects a wide variety of trees. Symptoms include small, brown spots on the leaves.
- Armillaria root rot: Armillaria root rot is a root rot disease that affects a wide variety of trees. Symptoms include yellowing leaves, wilting, and stunted growth.
When to Call an Arborist
If you think your tree may have a fungus disease, it’s important to call an arborist. Arborists are trained to identify and treat tree fungus diseases. They can also recommend ways to prevent future infections.
