First report of Colletotrichum fioriniae infection of hazelnut
In a 2008–09 study of hazelnut fruit cluster diseases in Ordu, Giresun, and Trabzon provinces of Turkey, brown to black sunken, circular to irregular lesions and rots were observed, usually at the bottom end of the hazelnut cluster, close to the pedicel. Colletotrichum species were most frequently isolated from the lesions, and 13 isolates were identified morphologically as C. fioriniae, and the identity of one of them was confirmed by molecular analyses. Pathogenicity tests were conducted under laboratory, greenhouse, and field conditions, and symptoms matching the original field symptoms were observed on leaves, fruit clusters, and pedicels. This is the first report of C. fioriniae as a pathogen of hazelnut (Corylus avellana) and the first record of C. fioriniae from Turkey.
