Abstract

Pestalotiopsis biciliata, Diplodia seriata and Diaporthe eres were recovered from severely diseased bunches of withered grapes for Amarone wine production. To our knowledge this post-harvest disease has never been seen before in withered grapes. Fruit rot occurred with bunches containing decayed berries partially or totally covered by whit- ish mycelium. Morphological and phylogenetic analyses of fungal isolates from symptomatic fruits enabled species delimitation. Pathogenicity tests re- vealed that the three species are able to infect grape berries confirming that they are casual agents of fruit rot. This study provides preliminary insights on this post-harvest disease that might have important im- plications in grape quality.
