| Sumario: | [EN] Loquat (Eriobotrya japonica) is a fruit tree cultivated in several countries in the Mediterranean region. A survey of a loquat orchard in Sicily ( Italy) revealed the presence of plants showing dieback symptoms and cankers with wedge-shaped necrotic sectors. Fungi from the genera Diplodia and Neofusicoccum were isolated from symptomatic plants. On the basis of morphological characters and DNA sequence data four species were identified, Neofusicoccum parvum, N. vitifusiforme, Diplodia seriata and a novel Diplodia species, which is here described as D. rosacearum sp. nov. Inoculation trials of loquat plants cv Sanfilipparo showed that N. parvum, D. seriata and D. rosacearum were pathogenic to this host. Although variability was observed between isolates, N. parvum and D. rosacearum were the most aggressive species. |
