Abstract

Apples (cv. Royal Delicious) dip-treated in wax emulsion containing 6% solids and a fungicide (Bavistin on active ingredient (a.i.) basis 1000 p.p.m.) and untreated apples stored for 42 days under ambient conditions (21-28 degree C, RH 30-80%) showed 6.3 plus/minus 0.5% and 9.3 plus/minus 1.7% physiological losses in wt. (PLW) and 36.0 and 59.4% shrivelling, resp. Fungal spoilage after 42 days storage was 8.3% in untreated and 2.7% in treated apples. Treated and untreated apples, when stored for 42 days under evaporative cooling storage conditions (22-24 degree C, RH 90 plus/minus 5%) showed 2.9% and 3.4% PLW, resp.; non shrivelling or spoilage occurred in either. A similar study carried out with coorg mandarins treated with 6% waxol with a fungicide (Bavistin on a.i. basis 1000 p.p.m.) gave storage life of 20 days under evaporative cooling storage conditions vs. 5 days for untreated fruits stored at ambient conditions. Thus, evaporative cooling storage gave 6x longer storage life for apples and 4x longer storage life for mandarins than at ambient conditions.
