First report of anthracnose fruit rot caused by Colletotrichum fioriniae on red raspberry (Rubus idaeus) in the Mid-Atlantic region of the United States.
In June 2019, 40% of red raspberry fruit (Rubus idaeus) cv. Prelude in a plot at the Wye Research and Education Center of the University of Maryland in Queenstown, MD, USA showed light to dark brown, rotten, and slightly sunken drupelets. The causal pathogen was isolated and identified as Colletotrichum fioriniae based on morphological characteristics, molecular data (sequence analysis of glyceraldehyde-3-phosphate dehydrogenase (gapdh) and β-tubulin-2 (tub2) gene) and pathogenicity test. This is thought to be the first report of C. fioriniae found on red raspberries in the Mid-Atlantic region of the United States.
