Sycamore Tree Fungus Leads to Diseases


Anthracnose is also known as leaf and twig blight. This is the most dangerous disease for the Sycamore and does more damage to some varieties than others. The first symptom people usually see are the leaves dying – the crinkle and turn brown.

Anthracnose is caused by the Sycamore tree fungus Apiognomonia veneta and is often mistaken for frost damage. The spores can spread by the wind and rain. Anthracnose can usually be prevented by taking good care of the tree and making sure it has enough water and fertilizer.

The treatment for anthracnose is to clean up fallen, diseased leaves and cut off dead twigs and branches. Make sure you disinfect your shears if you cut anything off a diseased tree so you won’t spread the disease. You can use preventive fungicides to keep the disease from getting the new leaves, but the best thing to do is to call a professional who can diagnose and treat the disease before it gets worse.

Powdery Mildew

Powdery mildew usually grows on Sycamores that grow in shaded areas with high humidity. It starts on the leaves and twigs as patches of white powdery material, hence the name. The patches can vary in color from white to gray. The patches can combine to cover the plant entirely with a thin layer of powder.

Powdery mildew is caused by the Sycamore tree fungus Microsphaera. Young parts of a tree are usually more susceptible than older parts of the tree. Leaves that are infected turn yellow and drop, with new growth being stunted in an infected tree.

If powdery mildew isn’t treated, the fungus will produce tiny black spores over the powdery substance, so the fungus can survive the winter. When spring comes again, another kind of spore will introduce more infection to the tree.

In some cases, the tree can be sprayed with a fungicide, but powdery mildew can develop a resistance over time and you’ll have a hard time killing it. If you suspect powdery mildew in your tree, our team of experts can identify what’s happening and recommend treatment to save the tree.

The best way to protect your trees against insects and Sycamore tree fungus that causes disease is to take good care of it. A hardy, healthy tree will be able to fight off diseases better than a nutrient-starved tree.
