Abstract : A study was conducted to know the impact of fungicides on shelf life of mango with an objective to reduce the postharvest losses. The investigation consisted of postharvest dip of fruits with different chemicals and their formulations during mango growing seasons of 2011 and 2012. Postharvest treatments revealed that fruit dipped in Difenconazole at 0.2% for 5 minutes in hot water (52°C) resulted in minimum percentage disease index (PDI) of 3.52 and 3.19%. The treatment showed the highest value of fruit firmness of 5.33 and 5.50 kg/cm2 with minimum physiological loss in weight (PLW) of 8.28 and 7.95 and maximum shelf life of 17 days. The fruits had acidity percentage of 0.36 and 0.34, maximum sugar content of 13.13 and 13.20% and gave maximum organoleptic scores with significant results.
