I have a large patch of echinacea that had a leaf spot issue last year. I cut them back in the fall and cleaned up as best I could. This year some of them have strange yellow splotches on the leaves. It looks as though someone spattered bleach on them. I don't think it is insect dammage as it is extensive and there are no holes at all. I have never seen this before. Oh! And I have never seen so many leafhoppers. I am worried they are spreading a virus.
