As Wayne's leading tree care experts, we've seen firsthand how tree diseases can impact our local urban forest. Understanding these common Illinois tree diseases and their treatments is crucial for maintaining healthy trees on your property.

Oak Wilt Disease

One of the most devastating tree diseases in Illinois affects our cherished oak trees. Oak wilt is particularly aggressive in Wayne and surrounding communities like Saint Charles and Batavia.

Symptoms of Oak Wilt:

Wilting and browning leaves, starting from the crown
Rapid leaf drop during summer months
Discoloration in the wood

Early detection and professional tree trimming can help manage oak wilt spread. In severe cases, emergency tree removal may be necessary to protect surrounding trees.

Dutch Elm Disease

This fungal disease continues to threaten Illinois elm trees. Our certified arborists frequently encounter this issue throughout Wayne and neighboring areas.

Treatment Options:

Fungicide injections
Root graft disruption
Proper pruning and sanitization

Apple Scab

Common in crabapple and apple trees, this fungal disease typically appears in spring. Learn more about seasonal tree care in our guide to Seasonal Tree Care Tips for Homeowners Across Illinois.

Anthracnose

This disease affects various shade trees, particularly sycamores and maples. It's especially prevalent in wet springs and can cause significant leaf drop.

Prevention and Treatment:

Improve air circulation through proper tree trimming
Remove and destroy infected leaves
Apply fungicides as preventative measure

Fire Blight

This bacterial disease commonly affects fruit trees and ornamental pears. For severe cases, check our Emergency Tree Services guide.
