Abstract

First report of Colletotrichum fructicola and C. queenslandicum causing fruit rot of rambutan (Nephelium lappaceum).

Abstract

In rambutan (N. lappaceum) production, fruit rot is the main pre- and postharvest disease. In a 2008-13 fruit disease survey in Puerto Rico, during August and September, fruit rot was observed in eight orchards. Infected fruits were collected for pathogen identification. Based on morphological characteristics, sequence analysis of the rDNA internal transcribed spacer region and pathogenicity tests, two causal agents were identified, namely C. fructicola and C. queenslandicum. C. gloeosporioides has been reported causing fruit rot of rambutan in Thailand and Sri Lanka. This is thought to be the first report of C. fructicola and C. queenslandicum causing fruit rot of rambutan.
