Fungicide resistance profiles of <i>Alternaria</i> spp. associated with fruit rot of blueberry in Georgia, USA.

ABSTRACT: Georgia blueberry growers experience significant losses annually due to fruit rots including Alternaria rot caused by Alternaria spp. Fungicide applications from bloom through harvest are typically recommended for management of fruit rots, however fungicide resistance development has the potential to complicate management activities by reducing fungicide efficacy. To evaluate fungicide resistance issues in Georgia, 46 isolates of Alternaria spp. from ripe blueberry fruit from four major blueberry-producing counties were collected and identified by morphological and molecular features. The majority of the isolates were Alternaria alternata (n=43) but also included Alternaria tenuissima (n=1), Alternaria dumosa (n=1), and Alternaria limoniasperae (n=
