It looks like I have aster yellow disease and I have a lot of purple coneflowers. I know some can have the disease but have no symptoms....should I pull all of them? My goldenrods look bad too. I have a LOT of each of these plants and I am very concerned. I have pics of my goldenrod too. Do I need to pull all these plants? If so, immediately? Thanks.

The recommendation is to remove infected plants. As you point out not all infected plants show symptoms. It is something you may want to live with by taking out those with symptoms and hoping that the leaf hoppers that spread the disease do not visit your garden next year.
So, you agree that this is aster yellow based on the pictures?
It does look like aster yellows is affecting your flowers.
