Abstract

Species of Botryosphaeria have been implicated in grapevine decline and dieback symptoms in Australian vineyards. In this study, we report the morphological and molecular identification of Botryosphaeria dothidea isolated from symptomatic grapevines in eastern grape growing regions of New South Wales, Australia. The pathogenicity of B. dothidea towards Vitis vinifera cv. Chardonnay is also confirmed.
