Beech Leaf Disease

Apparently we need to register for this Beech Leaf Disease Workshop.

"This is a targeted workshop for state and federal agencies and professionals in the field. Registration is required and space is limited due to room capacity!"

I just emailed John, the biologist who put out the fact sheet. It seems that some other samples came in from Mass that sound similar to what I saw but where attributed to a eriophyid mite. What I saw was definitely fatal though. I'm kinda disappointed that I did not pursue it more last summer. Busy time of year to be running plant samples back and forth to the ag station if you know what i mean.

Jed look up erineum mite galls on beech just so you know the difference and then can send in the samples you see to a lab.

This sucks doesn't it?
I'm going to try to attend but may do the Adobe interweb thing. We shall see.
 
You are probably not going to miss much on the "field trip".
The leaves here in NE Ohio are at least 2 - 3 weeks behind normal.
I don't have anything leafed out.
A couple maples are just starting to break out of buds.

Southern Ohio is a few weeks ahead of normal.
 
Background:
Holden Arboretum (just East of Cleveland Ohio) features 3500 acres of cultivated gardens and native forests, with over 20 miles of trails. The Arboretum also features the Canopy Walk, an elevated walkway 65 feet above the forest floor, and the Emergent Tower, a wooden tower that rises 120 feet above the forest floor for views of the surrounding landscape, and Lake Erie ~15 miles away.
A couple years ago, Holden Arboretum and Cleveland Botanical Garden joined together to make up Holden Forests & Gardens.
They do a lot the research & publish a quarterly magazine for the public.
"Forests Gardens, Winter 2018-19"

Article on Beech Tree Leaf Disease - Early identification of disease: (See pg 7 of 9 in Link; and See pages 12-13 in magazine article)

Beech Leaf Disease (BLD) continues to spread in Ohio & into Ontario, Pennsylvania, New York, etc.

Personally, the Beech, in my 10 acres of forest, seemed to decline more slowly than I expected for several years.
However, this year they seem to deteriorate more rapidly.
 
Been hearing more chatter this week about nematodes. Nothing official.

Newly discovered microscopic worm species eyed as potential cause of beech leaf disease

More than 50 arborists and botanists gathered for a workshop at the West Creek Reservation in Parma on Wednesday to discuss potential causes and cures for beech leaf disease, which was discovered in Lake County in 2012, and since then has spread to nine other counties, Pennsylvania, New York...

Jennifer Koch talked about these at the Division of Forestry's Forest Health Meeting a couple of weeks ago. Sounded pretty convincing...

That article is from May 2018? Must have been pretty new then...there was no mention of nematodes at last year's Forest Health meeting.

This is the same conference that I mentioned in this thread last April.
(See April 26, 2018 post)
I attended that conference.

I was not convinced, or even encouraged, by any particular theory at the time.
 
Excellent question.

At that time I fully expected the large trees, with only < 50% "good" leaves, to be dead in 2-3 years. They are not.
The small trees are much harder to keep track of, and I think many, but not all, have died.

The large trees, seem to be worse one year, and then a little better the next, then worse again.

None have recovered.

The original discoverer, has seem some large old trees die in some of his original plots (2012).
 
I forget the Dr's name, though he is the one that named and isolated the nematode down the road from us, but he thinks that many beech will survive with this for some time.
 
Our Beech tree appears to be infected worse this spring than 2019, more leaves damaged, all sides of the tree. Note: I posted a thread last year: Beech Tree / Brown Leaves. Although I do not see the "dark striping" on the leaves, I believe it must be Beech Leaf Disease (BLD). The damaged leaves (usually same branch) have random brown spots and appear withered with edges curling and dying. The only recommended treatment looks to be Sulfur or Copper Fungicides. How these treatments applied to a 60 ft tree? Also, our tree is home to approximately 50 - 75 birds, mainly sparrows and I would not like to harm them. Has anyone applied a successful treatment?
