I have a client who emailed similar photos of oaks, but not quite as severe as yours. Random total death of branches in established canopies. Researching I though it looked like Oak Wilt, however, UF says that is not in FL yet. Maybe it is now. He's bringing me sample next week for diagnostics. I'll appreciated any input on this issue too.

Subject: oak tree problem

I have an oak tree problem that has me stumped.
At first glance it looks like a pesticide problem, but the evidence is muddy at best.
