First report of botrytis blight caused by Botrytis cinerea on fruit-scented sage in Italy.


During the summer and autumn of 2015, symptoms of an unknown leaf blight were observed on fruit-scented sage (Salvia dorisiana) cultivated in a private garden located in the Biella province (northern Italy). Brown necrosis with irregular margins developed on both leaf surfaces, on the apices and along the borders. Sometimes, a soft, grey mycelium grew on affected tissues. The causal pathogen was identified as Botrytis cinerea based on morphological, genetic (ITS and BLAST) and pathogenicity analyses. This is thought to be the first report of B. cinerea on S. dorisiana in Italy as well as in the world.
