Thanks, Greg,

My trees are just starting to open up--and so far everything looks normal (except that very few of them held their old leaves over the winter, as they usually do).

I'll report back in a few weeks on how things are going in SE Massachusetts.

Already seeing symptoms on emerging leaves that look consistent with BLD here on LI. We’re recommending diagnostics in the field be done at full leaf expansion though. Broadform treatments when timed right are very effective.

Thank YOU for the update on this Jzack.

Fluopyram thank goodness.

Super expensive and will be hard to get unfortunately. Also the addition of being a foliar application I’m really hoping for an injectable/soil/bark applied product. I don’t know, still don’t think it’s our best option despite high efficacy for our large historic beech.

Has anyone heard of any options for the native beech in our forests?

That's the first I've heard that it has been found in western Ohio (Fulton County). Bummer!

This might be worth a read: https://www.sciencedirect.com/science/article/pii/S1319562X21007191#b0640


Quite a lot of insight on the Nematode insect, types and management efforts across the board.

Lots of additional, very detailed, propagation / distribution maps are now available on-line:

that doesn't quite look like Beech leaf disease? Maybe Erineum mites??? https://bygl.osu.edu/node/1311

@Serf Life
I don't see the dark streaks in the leaves.
Can you see streaks when looking up at the leaf bottom w/ the sky as a back light ?

Yes though not on every leaf, but also sent photos into the state and will hear back. It was first found just up the coast from us in 2021 and has ballooned since then.

Perfect, Thanks !

Confirmed by the state and first report from my town, bummed

Rhode Island beech are f'd, eastern Mass. beech are getting hit by the first round, native F. grandifolia, and landscape trees F. sylvatica effected equally. It's a total wipeout, another eco tragedy. Really sad to see the remnant old-growth beech forests on Aquidneck Island in RI completely toasted.

Bad news; Good news ?
Sad to see that BLD continues to spread.

In 2016 I wrote a TreeBuzz Article; and began posting on BLD. 100% of my 12 acres of forest (and my entire neighborhood) in NE Ohio were affected.
I am one county (Geauga) next to the first BLD identification location (Lake Co.; in 2012).

At the time, the leaf damage was such that I thought everything would be dead in 2-3 years.
Young trees have died; but surprisingly, older trees have survived. (help from “Mother trees” ? ? ?)
The older trees look better some years, and worse other years.
At best they look awful. But they are hanging on, but probably not forever.

Encouraging but with so many other stressors I can't see how the New England beeches are going to make it.
