Black dot (Colletotrichum coccodes) has become an economically significant potato tuber disease due to its capacity to cause early foliage death (Johnson et al., 2018). The disease named black dot relates to the numerous black microsclerotia that the fungus can produce on its host (Johnson et al., 2018). In August-September 2022, black dot symptoms were observed on c. 48% of potato stems (just above the soil level) (Figure 1), c. 27% of stolons and c. 22% of the skin surface of harvested tubers (Figure 2) in open fields [Goodlands (20°04'13.1“S 57°39'37.0”E), Réduit (20°14'00.5“S 57°29'28.5”E) and Plaine Sophie (20°22’23.0“S 57°29’08.4”E)] in Mauritius.
