Effect of Bioagents, Oils and Herbal Extracts on Post Harvest Diseases of Nagpur Mandarin

An experiment was conducted to study the effect of microbial bioagents, oils and aqueous extracts on post harvest diseases during storage of Nagpur mandarine- The fruits treated with citronella oil (2%) resulted in minimum physiological loss in weight (2.48%), higher average juice content i.e. 96.38% g/fruit, higher per cent of acidity (0.55) and TSS (16.20 brix) followed by fruits treated with turmeric leaf oil (2%) at 45 days of storage. Spoilage was less (14.81 %) in fruits treated with citronella oil (2%) followed by turmeric leaf oil (2%), which was 18.51%. The fruits treated with T. viride (104/ml retained higher amount of ascorbic acid (2%) and caster oil (2%). The fruits treated with citronell1a oil (2%) resulted in minimum physiological loss in weight (2.48%), higher juice content, acidity and TSS followed by fruits treated with turmeric leaf oil (2%). The ascorbic acid content was higher in T. viride at 45 days storage. Citronella, Carbendazim, turmeric leaf oil resulted in the minimum spoilage and mycoflora at 15, 30 and 45 days of storage.
