Arborist advice needed

[WoundedOne]

I have a Pin oak tree that has been healthy for several years that the wife and I planted. Last week I mowed yard and it was fine, within 3-4 days it turned brown. Not just a couple of leaves the whole tree. It looks like there is some Japanese bettle's or insect damage on some of the leaves but I have seen this before and it was just isolated to a few leaves. I have researched a little about this I wonder if it is Oak Wilt. No cure for Oak Wilt if this is the case. I am attaching a few pics that I have. I went to George Washington Carver State Park as it is close for advise and got nothing but a referral to MDC Neosho office. No response yet. I am concerned that this may affect other trees if in fact this is Oak Wilt.  Please advise on next steps.

 

Thanks Michael

Whether it is oak wilt or not, that sucker is dead, and ain't coming back.     

Bon fire time.

Normally those are tough….almost looks like a extremely harsh herbicide was used on it
