A neighbor has an oak which appears to have borers. Though it is called a Red Oak, from the picture of the trunk and leaf I do believe it's a Quercus alba?
A closeup picture of a leaf seems to have Tubakia leaf spot, which if it is, does not require treatment.
The tree is showing signs of branch dieback. It also has small holes on the trunk. There is no visible sap exuding nor frass visible.
If it is borers what would be suggested to eliminate them to save the tree? If it is not borers, what could be the problem and how is it to be resolved?
Several pictures have been attached. Thank you for guidance and stay safe!
Note: only three pictures were allowed for download. Will send more if I can
