Oak wilt is a serious disease that affects oak trees in Lake Nacogdoches, Tx. The disease is caused by a fungus that spreads quickly and can result in the death of the tree. The following are steps to identify, treat, and prevent oak wilt in Lake Nacogdoches.

Steps to Identify, Treat, and Prevent Oak Wilt in Lake Nacogdoches, TX

1. Identify Symptoms: The first step to manage oak wilt is to be able to recognize the signs. Look for a sudden change in color by leaves on live oak, Shumard red oak, and blackjack trees during summer or early fall. Discoloration develops near the outer edge of the leaf and quickly proceeds inward. Fungal mats can develop under the bark of infected red oak trees, and veins on wilted leaves often appear as black. In addition to these signs, look for the presence of wood discoloration.

2. Contact A Certified Arborist: Once you identify oak wilt symptoms, contact a certified arborist to offer an evaluation of your property’s trees. Identifying the type of oak species, the age, and the health status of the trees, the soil, the moisture levels, and the proximity of the trees to surrounding structures are also significant pieces of information to consider.

3. Laboratory Analysis: The arborists may take samples from the infected trees, and this may require laboratory analysis. The laboratory can analyze the samples taken and confirm the presence of the oak wilt fungus before developing a treatment plan.

4. Tree Removal: If the infected tree is severe, the arborist may suggest removing the infected tree. Removal of the infected tree is one way to manage the infection and stop the spread of the disease in Lake Nacogdoches.

5. Fungicide Treatment: A certified arborist could utilize fungicide injections to prevent the spread of the fungus responsible for oak wilt. Fungicide injections put the fungicide directly into the oak trees’ vascular system and allow for effective control and prevention. Arbortech is one of the most used fungicides for oak wilt treatment.

6. Tree Pruning: Proper pruning removes infected branches and can be an excellent management tool to slow the spread of the oak wilt. Pruning should be done during the cooler months of the year when the fungus is not active.

7. Preventive Measures: Prevention is the most effective way of managing oak wilt. Ways to prevent oak wilt include:

• Avoid injuring the tree

• Disinfect all pruning and cutting tools between cuts and amongst trees

• Don’t prune oak trees from February to June

• Creating a trench around infected trees can stop root transmission of the disease
