Occurrence of noni anthracnose caused by Colletotrichum siamense in Amazonas, Brazil

Noni (Morinda citrifolia L.) is native from Southeast Asia and was introduced in Brazil recently, where it has well adapted to the edaphoclimatic conditions. The fruits are consumed because of their numerous therapeutic properties. From March to November 2018, circular brown spots with concentric rings were observed on leaves of noni plants, at Federal University of Amazonas campus (UFAM), where the temperature and rainfall ranged from 23°C and 32°C, and 47 mm and 335 mm in this period.
