What is Anthracnose on Trees?

Anthracnose disease is actually a group of related fungal leaf and stem diseases. Deciduous shade trees are most commonly affected by this group of fungi. We tend to see more of this disease after a wet spring or summer, as this would be a time when the fungus can really thrive.

Anthracnose fungi can survive the Memphis winter in buds, twigs, and even fallen leaves.

Come spring, the spores are then splashed by the rainwater onto the tree or even carried by the wind. This fungus performs best in cool, wet weather as the spores can continue to spread. That’s why it’s most common in spring and early summer.

Once the weather gets hot and dry, Anthracnose disease generally stops spreading though, in certain species of trees (or periods of cool, wet weather), it can potentially persist.

The impact of Anthracnose disease can differ a bit, depending upon the species of tree.

  • According to the Agricultural Extension Service of the University of Tennessee, Anthracnose disease of Maple and Ash trees are seldom a serious threat. Ash anthracnose, however, can cause 50 percent defoliation in just a matter of days.
  • Dogwood Anthracnose can be more damaging to flowering Dogwoods and can have the potential to kill the tree.
  • Sycamore Anthracnose can really ravage a Sycamore tree, however, it rarely will kill it. But it’s important to know that any repeated infection over a period of time can definitely weaken the tree.

What are the Common Anthracnose Symptoms?

As you might have guessed some of the Anthracnose symptoms are going to differ depending upon the host that it is attacking. That can make it difficult to explain exactly how it might show up on your property.

But generally speaking, some of the signs that you might see include small dead spots on the leaves, browning around the veins of the leaves, twig death, and dying buds (early in the season). The latter is sometimes misidentified as frost damage since it is early in the season.

If a tree is heavily infected, the leaves might be distorted and shriveled. Premature defoliation is also common with a heavy infection Anthracnose symptom. A tree with Anthracnose might look in pretty rough shape. But the good news is that it rarely kills trees and they can definitely bounce back.

How to Treat Anthracnose

As with any tree disease, it’s always best to detect it early as this is when it is most manageable.

Pruning out some of the diseased or dead twigs and branches will help to prevent the further spread of Anthracnose disease and will also encourage good airflow throughout the tree (remember, wet conditions is where it survives and thrives).
