Post-harvest mango fruit health is equally important at national and international markets for attracting customers as well as receiving better prices. A systematic survey was conducted during October 2011 to assess the status of major post harvest diseases of mango fruits in the local markets of Punjab. The data regarding prevalence, incidence and severity was collected and then pathogen was isolated by tissue segment method. General and specific media were used to isolate the fungi and then eventually, frequency of each fungus was calculated media wise and location wise as well. The present study found that anthracnose and stem end rot diseases were 100% prevalent in the markets of Punjab. Present investigation revealed that Colletotrichum gloeosporioides, Lasiodiplodia theobromae, Alternaria alternata and Aspergillus niger were the fungal pathogens involved in anthracnose, stem end rot, Alternaria rot and Aspergillus rot diseases respectively and these were major post harvest diseases that damage the mango fruit. During study, it was also observed that malt extract agar and V-8 agar were the best media for the growth of Lasiodiplodia theobromae and Colletotrichum gloeosporides fungi. Present investigation forms the basis to study the post harvest fungal pathogens of mango for their pathogenic behavior, fungicides resistance and genetic variability which will be further helpful for developing and understanding of management of post-harvest diseases of mango.
