Abstract

Colletotrichum acutatum is known to have a wide host range and has become an increasingly important pathogen on many economic crops worldwide. This is the first report of Colletotrichum acutatum on mango in Sri Lanka. Colletotrichum gloeosporiodes together with C. acutatum are considered as causal agents of this disease. Colletotrichum acutatum was characterized by fusiform conidia and white to orange colonies with slight shades of light mouse grey aerial mycelia. Colletotrichum gloeosporioides produced grey colonies with a dark mouse grey centre and conidia were cylindrical. The other differences between the mango isolate of C. acutatum and C. gloeosporioides were the slower growth rate and extremely high tolerance of C. acutatum to the fungicide carbendazim.

Key words: Colletotrichum gloeosporioides, Hevea brasiliensis, carbendazim
