First Record of Colletotrichum anthrisci Causing Anthracnose on Avocado Fruits in Chile.

ABSTRACT: Anthracnose caused by Colletotrichum species is one of the most frequent and damaging fungal diseases affecting avocado fruits (Persea americana Mill.) worldwide. In Chile, the disease incidence has increased over the last decades due to the establishment of commercial groves in more humid areas. Since 2018, unusual symptoms of anthracnose have been observed on Hass avocado fruits, with lesions developing a white to gray sporulation. Morphological features and multi-locus phylogenetic analyses using six DNA barcodes (act, chs-1, gapdh, his3, ITS, and tub2) allowed the identification of the causal agent as Colletotrichum anthrisci, a member of the dematium species complex. Pathogenicity was confirmed by inoculating healthy Hass avocado
