Oak Wilt Prevention in Johnson City, Texas

Oak wilt is a fungal disease that is prevalent in Johnson City, TX. It is a contagious disease that can spread to other trees through various means. Limiting the spread of the disease is crucial in ensuring that all nearby trees remain healthy. Here are some tips to stop the spread of oak wilt in Johnson City, Texas.

  1. Pruning: Pruning should always be carried out in the dormant season, preferably between December and February. Any cuts on infected trees should be promptly sealed with a paint-like pruning sealer.
  2. Proper Tool Sanitation: The disease can be easily spread between trees by pruning tools. Therefore, it is important to disinfect the tools and equipment properly after use on an infected tree. A 10% bleach solution can be used to clean the tools, and alcohol or Lysol can be used to clean saw blades.
  3. Avoid pruning healthy oak trees unless it is necessary: It is better to avoid pruning the healthy oak trees within 50 to 75 feet of a diseased one unless it is necessary.
  4. Prevent Wound: To keep your trees healthy, avoid painting trees with any non-porous coatings such as asphalt emulsions or black tar.
  5. Mat Removal: Fungal mats beneath the infected tree’s bark attract sap beetles, the primary transmitter of the oak wilt disease. If mats are noticed, they should be removed to prevent further spread of the disease.
  6. Tree Removal: In extreme cases, removing infected trees is the most effective way to prevent the spread of oak wilt. When a diseased tree is identified, ensure that it is removed and disposed of properly.
  7. Avoid underground trenches and wires: When installing trenches or wires, avoid passing them through the root zone of living oaks to prevent contact with diseased roots.
