Common Tree Diseases in Oklahoma
Oklahoma’s landscape is home to a variety of native trees, from majestic oaks and maples to vibrant redbuds and hardy pecans. These trees enhance the beauty of our environment, provide shade, and improve air quality. However, Oklahoma’s climate—characterized by hot summers, unpredictable weather, and occasional droughts—can create the perfect conditions for tree diseases. Understanding the types of diseases that affect trees in this region and how Vision Tree Service can help is crucial for maintaining a healthy, thriving landscape.
5 Common Diseases for Oklahoma’s Native Trees
1. Oak Wilt
Oak wilt is one of the most destructive diseases affecting oak trees in Oklahoma. This fungal disease is caused by Bretziella fagacearum and spreads through root systems or by beetles that carry the spores from infected trees to healthy ones.
Signs of Oak Wilt:
- Wilting leaves
- Leaf discoloration, starting from the edges (yellow or brown)
- Premature leaf drop
- Sudden branch dieback
Oak wilt primarily affects red oaks, which often die quickly once infected, and white oaks, which may survive longer but still experience severe damage.
2. Cedar Apple Rust
Cedar apple rust is a fungal disease caused by Gymnosporangium juniperi-virginianae. It requires two hosts to complete its life cycle: cedar (juniper) trees and apple or crabapple trees. This disease can harm both types of trees, reducing their aesthetic appeal and fruit production.
Signs of Cedar Apple Rust:
- Bright orange, gelatinous galls on cedar trees
- Yellow or orange spots on apple leaves and fruit
- Premature leaf drop
3. Anthracnose
Anthracnose is a group of fungal diseases that affect various tree species, including sycamores, maples, and oaks. It thrives in cool, wet spring conditions, making Oklahoma’s unpredictable weather a contributing factor.
Signs of Anthracnose:
- Brown or black lesions on leaves
- Premature leaf drop
- Cankers on branches or trunks
- Twigs dying back
4. Dutch Elm Disease
Dutch elm disease, caused by Ophiostoma fungi, has decimated elm populations across the United States, including Oklahoma. The disease is primarily spread by elm bark beetles or through root grafts.
Signs of Dutch Elm Disease:
- Yellowing leaves (often called “flagging”) on a single branch
- Wilting leaves
- Bark splitting or peeling
- Vascular discoloration beneath the bark
5. Pecan Scab
Pecan scab is a fungal disease that primarily affects pecan trees, which are common in Oklahoma. The fungus (Fusicladium effusum) thrives in warm, humid conditions, making it a recurring issue during wet seasons.
Signs of Pecan Scab:
- Dark, olive-green spots on leaves, twigs, and pecan shells
- Reduced nut production
- Premature nut drop
- Defoliation in severe cases
