Abstract

A survey was conducted during November, 2012 to May, 2013 to assess the status of major post harvest diseases of papaya fruits in the local markets of Mymensingh. Average percentage of diseased fruits at the markets were 29.83 and diseased fruits ranged from 20.40% to 38.04% during the study period. Highest percentage of diseased fruits (38.04%) was recorded in the month of May, 2013 followed by March, 2013 (37.98%). The minimum percentage of diseased fruits (20.40%) was recorded in January, 2013 followed by December (22.68%). Total six post-harvest diseases was recorded, viz. Anthracnose, Fusarium rot, Stem end rot, Rhizopus rot, Aspergillus rot and Penicillium rot. Anthracnose showed highest mean incidence (14.17 %) followed by Fusarium rot (7.26%) where as Pencillium rot showed lowest mean incidence (0.70%). In the market, anthracnose showed maximum percentage of mean disease abundance (46.11%) followed by Fusarium rot (24.61%). The findings of this study revealed that total six post-harvest diseases are associated with ripe papaya in different markets of Mymensingh. Moreover, May is the predominant month of highest incidence and abundance of all diseases. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21235 J. Bangladesh Agril. Univ. 12(1): 25-28, June 2014

Summary

Introduction

Papaya (Carica papaya L.) is grown worldwide in the tropics and subtropics. In Bangladesh, it is one of the leading fruits in respect of acreage and per hectare production in Bangladesh. The availability of the fruit is reduced due to high level of post- harvest loss (Mondal et al, 1995). 39.9% post-harvest losses of papaya fruits were estimated in Bangladesh (Hasan, 2010). The value stands for post-harvest losses of papaya fruits is taka 132.91 crore (Hasan, 2010). One of the major reasons of post-harvest losses of papaya production is fungal diseases. Ripe papaya suffers from various post-harvest diseases all over the world. In Bangladesh, there is no information available on the post-harvest fungal diseases of ripe papaya which may occur during the growing season, at harvesting, handling, transport and post-harvest storage and during marketing, or after purchasing by the consumer. (i) To know the present status of post-harvest diseases of ripe papaya in Mymensingh district (ii) To see the incidence and abundance of post-harvest diseases of ripe papaya
