Oak wilt has over the years and still continues to present a huge problem in various areas. It is caused by a fungus referred to as Ceratocystis fagacearum, which usually clogs a tree’s vascular system.

Oak wilt normally spreads in two diverse ways. One way is through the root system where about 90% of fresh infections happen via the roots. The second way is through overland spread where picnic beetles pick the fungus from an infected tree to a healthy one. The picnic beetle normally targets healthy oak trees with wounds.

How to Treat and Prevent Oak Wilt

How does a tree service company fix Oak wilt? This is a question that lingers in the minds of a majority of people. Well there are a number of ways that these companies employ to treat as well as prevent the spread of oak wilt. Tree companies often avoid pruning oaks from the month of April to September as these months are the highest risk. During this time the picnic beetle is always busy as the oak trees emit the most sap thus attracting them.

Chemical Injections and How Effective are they?

Various chemicals can be used to inject oaks in order to save them. This method has an effectiveness rate of 80 – 90%.

In some instances, this is the only option available to save oak trees from oak wilt. White oaks, with less than 30% of visible wilt can be saved through injections when they are caught early enough. It is not possible to save red oaks once they have exhibited oak wilt symptoms unless they were caught early on.

Root Graft Disruption

This method involves cutting off the roots that are found between the diseased trees and the healthy trees thereby breaking the root graft. This is carried out with the help of a trenching machine or a vibratory plow. Most plows consist of a blade that can manage to go downwards for five feet or even more. The deeper this blade goes then the more likely that this treatment method will work.
