The Invasion of Oak Wilt in Ontario: A Growing Concern

Oak Wilt

Oak wilt, a devastating tree disease caused by the fungus Bretziella fagacearum, is increasingly becoming a significant concern in Ontario. This disease, which primarily affects red oaks, can lead to tree death within a single season, posing a serious threat to our local tree service and the overall health of our forests.

The spread of oak wilt in Ontario is alarming. The disease, which was once confined to specific regions, is now being reported in various parts of the province. The rapid spread of this disease is largely due to the transportation of infected firewood and the activities of sap-feeding beetles that carry the fungus from tree to tree.

Red oaks are particularly susceptible to oak wilt. Once infected, these trees can die within a few weeks to six months. The disease causes the tree’s water-conducting vessels to plug up, preventing water and nutrients from reaching the branches and leaves. This results in wilting, bronzing, and eventually, the death of the tree.

Prevention

Preventing the spread of oak wilt is crucial to maintaining the health of our forests and the services provided by local tree companies like Kingston Tree Service. One of the most effective prevention methods is to avoid wounding oaks from April through July, when they are most susceptible to infection. If trees must be cut during this high-risk period, it’s important to immediately apply water-based paint or shellac to the cuts. This prevents sap-feeding beetles, which are attracted to the sap of freshly cut trees, from infecting the tree.

Treatment

In addition to prevention, there are also treatment options available for trees infected with oak wilt. These include injecting the tree with a fungicide to kill the fungus and using a technique called vibratory plowing to sever the root connections between trees, preventing the spread of the disease.
