Is It Oak Wilt, Or Not?

Oak wilt is a very serious and often deadly disease of oaks, specifically the oaks in the red or black oak group. The actual pathogen (Bretziella fagacearum) that causes the disease has been known to be in Ohio for many decades. Some years, it is worse than others. Oak wilt is not like the emerald ash borer that spreads rapidly, almost like a tidal wave moving in one direction. Oak wilt builds in a way that it can radiate out to other like trees, but advances at a slower pace, but even then, can cause tree death in a single season, and often in a matter of weeks
