Abstract

First report of Colletotrichum truncatum causing anthracnose in tomato fruit in Trinidad.

Abstract

From August to November 2017, fruits with symptoms typical to anthracnose infection were reported on tomatoes (Solanum lycopersicum) in Aranguez, Trinidad. Fruits exhibited symptoms of a sunken, watery lesion with deposition of setae seen as concentric rings. The causal pathogen was isolated and identified as Colletotrichum truncatum based on morphological, molecular and pathogenicity analyses. The obtained sequences were deposited in GenBank as accession numbers MG822826 to MG822829 (ITS), MG839686 to MG839689 (Î’-tubulin) and MG870322 to MG870325 (actin). It is proposed that C. truncatum originated in a field of bell peppers with subsequent cross infection in tomato fields. This is thought to be the first report of anthracnose disease caused by C. truncatum on S. lycopersicum in Trinidad.
