The sight of fungus on the bark of your tree isn’t particularly appealing. Imagine spending a lot of time maintaining your tree, only to see scabs on the branches. Unluckily, tree fungus is one of the most popular conditions that affect trees. It can also lead to the death of your tree if left ignored.
Though the growth of lichens or shelf mushrooms on your tree is pretty safe, there are a couple of types that can be deadly for your tree. Seeing fungi on your tree should be a cause of concern. The reason for this is that it can greatly influence your tree’s structural integrity. Today, we’re going to share with you some of the most common deadly fungi in trees. If you spot one, make sure you hire a Sioux Falls tree service company for help.
As the name implies, this condition affects a beech tree’s bark. The main cause of this fungi is the mutual relationship between the European beech scale insect and Nectria fungus. First, the beech insect will feed on the sap by attacking the tree’s bark. After it has access inside the tree, the fungus will colonize the bark. This will lead to damages inside the tree. It can also lead to blisters, oozing wounds, and unappealing cankers on the bark. If this fungus attacks your tree, it will leave it in poor condition. This makes your tree more prone to other illnesses.
Professionals typically suggest strong chemical treatment protocols to prevent the spread of this illness.
Trees that are at risk of this fungal illness are the bark of hardwood fruit trees. Irregular pruning, natural damage, or insects can cause wounds in the bark. This makes it simpler for the fungus to have access. The bark will gradually turn reddish-brown in color. After a couple of weeks, the bark will shrink and become black. This causes it to peel off by itself.
Your tree’s vascular system can be drastically affected by black rot disease.
If you see disgusting swellings on the bark of your tree, it is probably a black knot. Trees such as apricot, plum, or cherry are at high risk.
At first, the swellings will have a greenish-brown color. After a couple of months, they will become black. This will provide your tree an ugly look. Regular pruning can easily help prevent the occurrence of a black knot in your tree.
Dutch Elm Disease
Dutch elm disease is an invasive fungal infestation. They usually attack different types of elm trees. An elm bark beetle can spread this disease through fungal spores. The beetles usually directly dig into the bark to lay eggs. The larvae will then bore deeper into the tree when they hatch. They’ll consume healthy tree sap while affecting the tree’s vascular system.
Since your tree will attempt to block the fungus’ spread, it will end up blocking crucial nutrients from circulating. The tree will slowly start to wilt and will die eventually after 1-2 years. The best course of action is to inject a fungicide into the bark.
