Presence of Colletotrichum acutatum causing anthracnose on hot pepper in central Italy.


In October 2013, during a survey in chili pepper cultivations of central Italy, fruits of Capsicum annuum were collected, showing circular sunken lesion with concentric rings of acervuli that produced pink to orange conidial masses. Based on morphological characteristics, sequence analysis of the DNA internal transcribed spacer region and pathogenicity tests, the causal agent was identified as C. acutatum. In Italy, C. acutatum causes damages to strawberries and other crops, but it has never been found in hot pepper. Colletotrichum species are generally seed-borne, so infected seedlings and seeds may be a way for their introduction in new cropping areas.
