Oak wilt should not be taken lightly. In fact, it is ranked as one of the worst tree diseases in the United States. Caused by a fungus called Ceratocystis fagacearum, the disease can spread epidemically because it is highly infectious. It kills trees because it invades the water-bearing systems in trees susceptible to it.
The Most Susceptible Types of Oak Trees
Although all oak trees are susceptible to this fungus, some oak varieties are more vulnerable than others.
The oak trees most susceptible include:
• Red oaks, like the Spanish oak.
• Texas red oak.
• Shumard oak
• Blackjack oak.
What Happens To Trees Infected With Oak Wilt
Here are the patterns affecting tree mortality:
• Most trees first defoliate, and then die within one to six months.
• Red oaks are the most vulnerable and seldom live out the month after infection. In summer infected red oaks have autumn colored leaves.
• Sturdier trees don’t die, but live on in a state of decline.
• Sometimes a few oak trees escape infection altogether--although the reasons for their hardiness have not been fully identified.
Oak Wilt Analysis
There are four ways to identify if a tree is on the decline due to Oak Wilt:
• Leaf symptoms.
• Tree mortality patterns.
• Fungal mats.
• Laboratory tests.
