Oak Wilt Treatments
Treatment For Individual Trees & Entire Neighborhoods
Two treatments for oak wilt have been tested by scientific research and proven effective in most cases when done properly: fungicide injection and trench installation.
  • Fungicide injection for individual oaks at imminent risk of infection
    • Prevents symptom development, but does not stop the movement of the oak wilt fungus through the roots to nearby oaks
  • Oak wilt suppression trenches for entire neighborhoods
    • Stop root transmission through large areas but can't save oaks closest to infected oaks

Note: These two methods are often used together.
