At Rockoff Tree Solutions we work tirelessly to identify oak trees infected with Oak wilt. Trees don’t always show the classic symptom of veinal necrosis making visual diagnosis much harder to the untrained eye. Rockoff Tree Solutions uses DNA testing as well as the traditional methods used by plant pathology labs to ensure that we have a proper diagnosis. Sometimes a tree can look like it has Oak wilt and treating for that fungus without confirmation may result in the tree continuing to decline in health. Although DNA testing is relatively new (approved by the USFS and USDA in 2017, it has provided us with a quicker turn around time to treat the infection.
