I don't think .so.It looks like weevil damage in the one's that are opened . The other ones just look like buds that haven't opened yet. You may also get buds that just have the cone and no petals from mites. Also with asters yellow the foliage will usually ( but not always ) have chlorosis, yours looks very healthy but I would still keep a close eye on .them..Here are some pics that should help ID the problem. Also you should snip off the flower heads that have mite damage and clean good the fall to get rid of the mites, they live inside the cone. Also look over flower heads for weevils, small black beetle looking bugs and knock them ofoff Into a bowl with water and dishdish soap ,they can swim out of just .water

Thanks Beesandblues, that's very good info you've shown. Thankfully, mine "so far" have been healthy, I did have asters yellows when first moving to this property, though haven't had a reoccurrence in a good dozen years.

Thank you Beesandblues! I'm going to keep an eye on them as they bud out further and compare with your picks. That one white one in my pic sure looks like the damage of eriophyid mites with the way the petals are distorted.

If I remember correctly the pictures are from Ohio State University so they are a reliable source,, I downloaded tthem for quick reference. I ripped up many plants that I'm sure never had Asters Yellow before learning about other things that can be mistaken for AY so glad to .help
