Comparing qPCR and Nested PCR Diagnostic Methods for Aster Yellows Phytoplasma in Aster Leafhoppers [PDF]
Plant Disease, 2016 The aster yellows phytoplasma (AYp) is a wall-less bacterium that causes damage in multiple crops. They are spread primarily by the aster leafhopper, Macrosteles quadrilineatus (Hemiptera: Cicadellidae). A total of 3,156 aster leafhoppers were collected during the 2014 and 2015 growing seasons in Michigan celery and carrot fields using sweep nets. The
