Abstract:

Anthracnose symptoms consisting of necrotic spots on the leaves, twigs and branches were observed on mango trees of cv. Kensington Pride in orchards located in the countryside of Palermo and Milazzo (southern Italy). Based on morphological observations and phylogenetic analysis of the β-tubulin (benA) and histone H3 (HIS3) genes, three Colletotrichum species were identified and recovered from diseased plants, i.e. C. karstii (nine isolates), C. kahawae subsp. ciggaro (six isolates) and C. gloeosporioides (six isolates). Following artificial inoculation, all species induced symptoms on the leaves and fruits of cv. Kensington Pride. To our knowledge, this is the first report of mango anthracnose caused by C. karstii, C. kahawae subsp. ciggaro and C. gloeosporioides in Italy.
