Abstract
During 2009 and 2010, twenty-one isolates of
Pestalotiopsis
spp. Associated with grey patches on the leaves, twigs, and panicles of mango were collected in six orchards located in Sicily (Italy). Morphological characteristics of colony (colour and mycelium appearance), and conidia (size, shape, septation, length and the number of apical and the basal appendages) as well as phylogenetic analysis of the Internal Transcribed Spacer (ITS) region (ITS1, 5.8S gene, and ITS2) of six representative isolates revealed the occurrence of
P
.
uvicola
and
P. clavispora
. The representative isolates of both species were pathogenic to the artificially inoculated detached mango leaves cv. Kensington Pride and showed significant variation in lesion size. This is the first report worldwide of
P. uvicola
and
P. clavispora
causing grey leaf spot of mango.
