Influence of Pre-Harvest Bagging on Fruit Quality of Mango (Mangifera indica L.) cv. Langra

Abstract

Fruits are susceptible to insect pest infestations, bird attack, various pathogens, and mechanical damages, all of which can reduce their commercial value and thereby cause significant yield and economic losses. The objective of this study was to control mango pests and diseases as well as to improve the fruit quality of mango through bagging technology. An investigation was performed during the year 2016 from March to July for safe mango production by applying minimum use of pesticide entitled studies on influence of bagging on physico-chemical properties and shelf life of mango cv. Langra. The mango fruits were bagged at marble stage (40 days from fruit set) with different types of bags which constituted the various treatments viz: T1: Brown paper bag; T2: White paper bag; T3: Polythene bag T4: Muslin cloth bag; T5: No bagging (control). Bagging with brown paper bag and white paper bag improved fruit retention, weight of fruit, diameter of fruit, pulp weight, total soluble solids, ascorbic acid, percent of citric acid, reducing sugars and β-carotene at harvest and ripe stage over control. Brown paper bag changed fruit color. In all cases good quality, cleaner, disease and insect free fruits were harvested. The sensory qualities in fruits of brown, white and muslin cloth bags were improved over control. Pre-harvest bagging also reduced occurrence of spongy tissue and the incidence of mealy bugs. These results indicate that fruit bagging can improve fruit quality through reduction in disease and insect-pest attack and shelf life of mango cv. Langra.
