Did you get the phytopthora results yet?
What's killing arborvitae?

Any chance it could be Pestalotiopsis or Phomopsis? Do you know the planting history on any of them? I've seen some uptick in phomopsis.

The phomopsis I've seen in the past has usually started by killing tips before moving to the rest of the branches. This just seemed to take it all out at once.

Positive.
Granted, that's just one. But at least I feel like we might be on the trail. Will start testing others as the calls come in.

That looks more like a tip blight or wind (salt?) burn.

Not salt, they have an issue with a utility contractor, but end of a dirt road wooded dead end. Mostly protected area. Could be tip blight, very uniform.
Will be going back this summer for another consult. Just thought "arbs"

Tissue sample or soil sample? The hard thing is just because it’s present in soil doesn’t have to be the causal agent.
Can chase it by removing the symptomatic trees or just start over with resistant plants. By the photos it looks like drainage may be a issue.

Tissue sample.
Some from the original picture were on a mound...a mound built from the spoils digging up a pond, but not a low spot.
Everything here is a wet spot...it's very flat and all clay. But most of these haven't been in wettest.

What’s the variety of the arborvitae? I know the American and Green Giant thuja seem less likely to get the diseases. I see a lot of discussion on local social media about them dying. I’ve looked a few and it’s always the oriental varieties. My 2 cents.

Pretty sure these have all been T. occidentalis
A lot of Emerald Green (Smaragd)
