Oak Wilt Treatment & Prevention in Austin, TX
Licensed systemic Alamo® propiconazole macro-infusion, root flare trenching, and strict preventive care to protect Central Texas live oak mottes from Ceratocystis fagacearum.
Identifying Oak Wilt Symptoms: Veinal Necrosis & Rapid Leaf Defoliation
Recognizing early vascular symptoms of oak wilt (Ceratocystis fagacearum) is vital to saving live oaks (Quercus virginiana). Unlike drought scorch which browns leaf margins, oak wilt causes veinal chlorosis and veinal necrosis.
Leaf veins turn yellow and bronze while surrounding leaf tissue stays green, followed by rapid leaf drop throughout spring and summer. On red oaks (Spanish and Shumard oak), entire crowns turn bronze and die within weeks.

Biology of Ceratocystis Fagacearum: Beetles, Fungal Mats & Root Grafts
Oak wilt spreads through two pathways: nitidulid sap beetles carrying spores from red oak fungal mats to fresh pruning cuts, and subterranean root graft transmission between connected live oak mottes.
Once inside the vascular system, the fungus travels through root connections at 75 to 150 feet annually, killing entire stands unless root grafts are severed.
Systemic Alamo Macro-Infusion & Root Flare Air Spade Excavation
Texas A&M Forest Service research confirms that systemic root flare macro-infusion of Alamo® (propiconazole) fungicide is the only proven chemical treatment. Shallow trunk micro-injections fail to distribute adequate volume.
Stump Bros uses supersonic air spades to uncover root flares without damage. Certified applicators drill clean ports into active xylem flares every 4 to 6 inches, connecting pressurized lines that deliver therapeutic dosages into the canopy.
What Is Included: Comprehensive Oak Wilt Treatment Deliverables
Our clinical oak wilt service delivers comprehensive canopy and root care:
Step-by-Step Root Flare Injection Protocol for Live Oaks
We follow a five-step therapeutic protocol:
Flare Exposure
Clear mulch and soil with an air spade to expose active root flares.
Port Drilling
Drill shallow holes every 4–6 inches into xylem tissue below soil grade.
Harness Setup
Connect injection tees and pressurized tubing attached to the chemical reservoir.
Dosage Uptake
Monitor solution absorption over 2 to 4 hours until the full dose enters the canopy.
Restoration
Disconnect tees, sanitize equipment, and replace soil around the root collar.
Containment Trenching & Severing Interconnected Root Grafts
While fungicide protects individual trees, mechanical trenching halts subterranean spread through root connections. Cutting 4 to 5 feet deep with rock saws creates an impassable barrier.
Trenches must be placed 100 feet ahead of the outermost symptomatic trees to sever root connections before fungal mycelium advances.

Frequently Asked Questions About Oak Wilt Treatment & Prevention
Clear, honest answers regarding tree health, emergency storm triage, permits, and pricing.
The hallmark symptom of oak wilt in live oaks is veinal chlorosis and veinal necrosis, where leaf veins turn yellow and then bronze brown while the leaf blade remains green. Unlike summer heat scorch which browns the outer leaf margins, oak wilt causes rapid defoliation of partially green leaves throughout the canopy.

Mark McIntyre
“Luis, knocked on the door. I wasn't looking, but he told me what he could do to get rid of partially ground stumps when I had the trees taken down. He had the right equipment and impressed me. I am a pretty good judge of character and was right about him...he is a hard worker. They ground 2 stumps for me, did a great job and I highly recommend them. His card says: Stump Grinding, Tree Removal and Lot clearing.”
