Abstract: The pre-harvest study was conducted in an experimental orchard and post-harvest laboratory of the department of Horticulture during 2013–14 with a view to investigate the effect of chemicals and pesticide application on ripening and fruit quality of mango under ambient condition. The levels of totals sugars in pre-harvest treated fruits ranged from 11.73 to 14.75 per cent. The application of 3% Dehydrated Calcium chloride + 0.1% Carbendazim resulted in higher levels of total sugars (15.08%) followed by Dehydrated Calcium chloride (14.23%), Silver nitrate (13.95%) and Calcium chloride (13.47%). During ripening, lowest levels of sugars were recorded in control fruits (12.15%).Percent increase in total sugars content in fruits over control was also found to be maximum with 3% dehydrated calcium chloride + 0.1% carbendazim (+ 28.55%), while the minimum increase of 12.27% in total sugars content in fruits over control was recorded with 2% calcium chloride. When compared the combined effect of treatments and their concentrations on total sugars content in fruits, it was 3% dehydrated calcium chloride + 0.1% carbendazim treatment.
