Abstract

A study was conducted to assess the potential of neem leaf extract, Aloe vera gel and Chitosan on the quality of two tomato cultivars (Sahil& Rio Grande) during storage in comparison with traditional post-harvest fungicide thiophanate methyl. Total soluble solids, acidity, color, respiration rate and ethylene production of bio-pesticides, treated tomatoes were compared (at 7 day interval, till 35 days) with those of treated tomatoes (thiophanate methyl) and control sample. Treated tomatoes (both varieties) were stored at 10oC and 75% humidity without CO2 and with 3% CO2 for 35 days in two different environment chambers. The selected parameters which affect the post-harvest quality loss were significantly controlled in the treated tomatoes (neem leaf extract and stored with 3% CO2) as compared to control and all other treatments except thiophanate methyl that also showed a significant effect.
