Oak wilt is one of the most destructive tree diseases in Texas, especially in the Texas Hill Country and Central Texas. At Oak Wilt Pros, we specialize in professional oak wilt injections that protect and preserve your valuable trees across Central Texas.

Why Treat for Oak Wilt?
Oak wilt is a devastating disease that threatens oak trees across Central Texas, including Austin, Dripping Springs, Wimberley, Fredericksburg, Marble Falls, Blanco, Lakeway, and surrounding areas. Our systemic fungicide injections help protect trees before infection occurs and slow disease progression in affected trees.
- Preventative treatments are most effective, with success rates of 85-90%.
- Therapeutic treatments can help reduce further decline but depend on tree health and disease progression.
- Monitoring tree response is crucial for assessing treatment effectiveness and long-term health.
What are Oak Wilt Injections?
Oak wilt injections are a proven treatment method that involves injection a fungicide directly into the vascular system of oak trees. This helps:
- Prevent transmission to surrounding trees
- Strengthen tree immunity
- Halt the spread of the oak wilt fungus (Bretziella fagacearum)
Why Choose Injections for Oak Wilt Treatment?
In the unique climate of Central Texas, oak wilt spreads rapildy due to interconnected root systems and high beetle activity. Trenching can help, but oak wilt injections provide internal defence that complements external prevention.
Benefits of tree injections:
- Targets the fungus from within
- Preventative for healthy trees within range of disease
- Most effective when applied early
- Recommended by certified arborists

Best Method for Oak Wilt Treatment
The macro-injection method is the most effective oak wilt treatment, recommended by the Texas Forest Service.
Our Macro-Injection Process:
- Flare root excavation – Ensures optimal fungicide distribution.
- Injection tees inserted around the flare for even displacement.
- Low-pressure containers deliver Alamo® (Propiconazole), the leading fungicide for oak wilt treatment.
- Custom dosage based on tree size (DBH) to maximize effectiveness.
- Adjustments for high-damage trees or those with canopy loss.
Some trees may not fully absorb the treatment due to health conditions, canopy density, or disease progression. A follow-up assessment ensures proper uptake and effectiveness.
Which Trees Should Be Treated?
Timing is crucial for successful oak wilt treatment.
- Preventative injections are ideal for trees within 100 feet of an infected area, increasing survival chances.
- Trees not yet showing symptoms near infected sites are the best candidates.
- Therapeutic injections are considered for high-value trees to slow disease spread and minimize damage.
Signs Your Tree Needs Treatment
- Rapid leaf discoloration (browning from leaf tips)
- Wilting leaves in spring or summer
- Dead branches or sudden canopy loss
- Nearby oaks recently diagnozed with oak wilt
