Old timer taught me the 'bark test' for oak wilt and I still use it every day

I was on a job in Austin Texas last spring and this older guy walks up while I'm staring at a live oak. He asks if I'm trying to figure out if it's got oak wilt. I nodded and he just grabs a chunk of bark near a crack and peels it back real careful. Underneath there was this grayish streaking in the wood. He said if you see that and the leaves are bronzing but not falling off, it's almost always oak wilt. The test has saved me from misdiagnosing like 12 trees since then. It's way more reliable for me than just looking at leaf drop alone. Anyone else use something that simple to ID tree diseases on the spot?

Tbh that "bark test" thing resonates with me way more than I expected. It's crazy how we've got all these fancy diagnostic tools now but the simple hands-on stuff still works. @black.oliver probably knows what I mean, same with the chalk trick - it's like we've overcomplicated everything when the old methods were already solid. Honestly I see this pattern everywhere, not just with trees. People trying to fix stuff with apps or expensive gear when a quick visual check or a feel test tells you the same thing. Ngl, there's something to be said for keeping those basic skills alive even when tech keeps trying to replace em.

Man that's a solid tip, gotta respect the old school methods.

Remembered my grandpa had this old trick where he'd use a piece of chalk to mark his tools before sharpening them. Worked weirdly well for keeping the angle right. Idk why we don't do stuff like that anymore.
