Aster yellows is a plant disease that can infect many plants. Infected plants have yellow leaves and stems, stunted growth and small malformed flowers. The aster leafhopper can carry the aster yellows pathogen. Plants become infected when fed on by leafhoppers carrying the pathogen.

Other wildlife use asters to a limited degree.
