Preventing Aster Yellows By Clint Brown on June 7, 2010 Aster yellows is caused by a tiny organism called a phytoplasma. The phytoplasma is spread from plant to plant by leafhoppers, which feed on the sap of the plants. Since no treatment is available to save an infected Echinacea, Aster yellows is best managed by removing infected plants and controlling leafhopper populations. |
