Aster Yellows
Aster yellows was common in 1999 and 2000. It produces plants with a purplish color (more than in healthy plants) and a shortening of the upper portions of the plants resulting in a "witches' bloom" appearance. The most noticeable symptom are hollow, bladder-like pods.
Aster yellows is carried by the aster leafhopper. Most of the hoppers carrying the aster yellows phytoplasma blow in from area to the south of us. There is no control.
