Colletotrichum gloeosporioides causes anthracnose on grapefruit (Citrus paradisi) in Mexico.

The grapefruit (Citrus paradisi) is an important crop for citrus farming in Mexico. During June 2019, in a plantation in Iguala, Guerrero, Mexico, symptoms of anthracnose on grapefruit fruits were observed. Based on morphological and molecular characterisation, the fungus isolated from the anthracnose was identified as Colletotrichum gloeosporioides. Koch's postulates were verified and fulfilled. To our knowledge, this is the first report of C. gloeosporioides causing anthracnose on grapefruit fruits in Mexico. [ABSTRACT FROM AUTHOR]
