Bronzing of serviceberry/amalanchier leaves #876206

One of two non-native serviceberries we ordered had a few leaves that were half bronze. I thought it was sun scald so wasn't worried until it spread to the second serviceberry plant so I now suspect it's a virus or fungus. Can you please ID it and tell me how to deal with it, preferably organically? Thank you.

Good morning,
We cannot diagnose from photos but suggest you bring in a sample to the Boulder County extension service for diagnostics.
It is also helpful to the diagnosticians to have photos of the plant.
Send photos full shot, close shot, and specific area of concern, to <personal data hidden>.
For Diagnostics: Turn around is up to 10 business days. $7.00 cost to Boulder County residents.
Bring sample to Boulder Extension office, 9595 Nelson Road in Longmont, by the fairgrounds. 8-4:30 Mon-Friday.
Provide a branch about 18” in length with both good and bad on same sample (must have living tissue) in a plastic bag.
Fill out a diagnostic request sheet at window and pay the fee.
I am attaching some information which may help you about serviceberry problems from the University of Minnesota.

Oops. I thought I had attached a photo. I have attached it here, though I understand that you need a sample brought in.

Thank you! When you bring your sample in, please reference the Ask Extension email.
