Abstract

First report of postharvest Stemphylium rot of mango (Mangifera indica) caused by Stemphylium vesicarium in Pakistan.

Abstract

In July 2017, infected mango fruits showing internal fruit rot were collected from fruit markets of Faisalabad, Punjab Province, Pakistan. The average temperature at the sampling sites was 38°C high and 28°C low with 75 to 80% relative humidity. The disease incidence of fruit rot was 18% on the examined fruit with 45% prevalence. On infected fruits, initially, irregular sunken purple to brown lesions were observed that later enlarged in surface area and ultimately caused internal fruit rot. The pathogen was isolated from an infected portion of the fruits and identified as Stemphylium vesicarium based on morphological and molecular characteristics and pathogenicity. This is thought to be the first report of S. vesicarium infecting mango fruit during postharvest storage in Pakistan.
