Mango is one of the world's most important fruit crop. It is the major growing fruit crop in Pakistan. At all stages of its life it suffers from a number of diseases. The main post-Harvest disease of mango is stem end rot which is caused by Lasiodiplodia theobromae. Other pathogens associated with disease are viz. Colletotrichum gloeosporiodes, Alternaria alternata, Aspergillus niger and Botrytis cineria. It causes severe losses in storage and market. The investigation was done at mango cultivar Samar Bahisht Chaunsa. The mature mango fruits were collected from the selected orchards. The samples were stored at ambient temperature (25 degree C) and cold storage (12 degree C). The diseased fruits were removed and the pathogens associated were isolated and identified and frequency is calculated. L. theobromae was most devastating fungus. At ambient temperature maximum percentage of L. theobromae with mean value was 47.31% followed by C. gloeosporioides with mean frequency of 20.84 %, A. niger 15.03% B. cineria 10%, and A. alternata showed least mean frequency 6.81%. At cold storage L. theobromae was maximum having the frequency 49.25% followed by C. gloeosporioides with mean frequency of (20.75%), B. cineria (14.03%), A. alternata (11.89%) and A. niger showed least mean frequency 4.23 %. Different plant extracts viz. D. stramonium, A. sativum, A. indica and C. intybus were used. Maximum inhibition of C. gloeosporioides and A. niger was shown by A. sativm. In case of A. alternata maximum inhibition was shown by D. stramonium and A. indica showed the maximum inhibition of B. cineria and L. theobromae.
