In vitro studies, aqueous extract of leaves of plants namely Karu (Roylea elegans), Artemisia (Artemisia roxburghiana), Neem (Azadirachta indica), Bana (Vitex negundo), Tulsi (Ocimum sanctum) and seed of Darek (Melia azedarach) were found effective in inhibiting the growth of the B. dothidea causing white rot in apple. These botanicals were mixed together and formulations were made in water (Botanical Formulations 1) and Cow urine (Botanical Formulations 2) on weight and volume basis. These two Botanical Formulations were evaluated against the disease along with chemical fungicide (Score) as fruit dip, dip of fruit wrappers and dip of fruit trays. Edible wax was also used in surface coating of the fruits. Skin coating of fruits in BF1 and BF2 was done by dipping the fruits in different treatment solutions for 30 minutes. From the present study it was concluded that different treatments have effects on quality parameters and shelf life of apple after 30 days of storage in comparison to untreated fruits as control. Different treatments i.e. fruit dip or impregnation of the packing material (trays or wrappers) with botanical formulations (BF1 and BF2) were significantly effective in reducing the physiological weight loss of fruits and retaining the fruit TSS, titratable acidity and firmness of apple fruit under storage. Fruits treated with BF2 were also found equally effective in retaining minimum fruit TSS (11.98 0Brix), maximum titratable acidity (0.28 %) and fruit firmness (14.97 lbs/sq.inch) after 30 days of storage. Treatment with BF2 was found effective as edible wax coating in reducing the physiological weight loss by 3.61 and 3.33 per cent respectively, during storage.
