“…Mango imports to the United States (US) and Europe have grown steadily in response to increased demand and affordable prices (Sauco 2004). When consumed regularly, mango can be a valuable dietary source of many phytochemical, which also impart a characteristic capusine yellow or reddish colour and distinct sweet rich flavour to the fruit which is contributed by the volatile flavour compounds present in it (Johnson et al 1997, Grundhofer et al 2001Haard and Chism 1996). It is also considered as a source of antioxidants including ascorbic acid (mango fruit provides about 50% of the recommended daily intake of vitamin C) and carotenoids, which are lipophilic radical scavengers found in many fruits and vegetables.…”

Postharvest quality of Alphonso mangoes (Mangifera indica L) is vital to ensure proper ripening and good quality. 500 g mature green mangoes, were subjected to three pre-packaging hot water dips (20, 30 & 40°C) for 40 min, two packaging films (OPP unperforated and perforated), using three levels of gas concentrations of 25,50 and 75% v/v CO 2 treatments (balance N 2 ) and stored at 10°C for 21 days. During the storage period headspace gas composition, weight loss, ascorbic acid, pulp firmness, external fruit colour and overall quality score were measured to determine optimum storage conditions. The most effective postharvest condition was found to be dipping in water maintained at 40°C for 40 min, followed by packaging under 50% CO 2 in bags made of unperforated film when compared to mangoes packed under 25 and 75% CO 2 which showed deteriorated quality including spoilage and mould. Good keeping quality of at least 21 days was achieved under these conditions, which was much superior to the control samples that showed deterioration after 12 days of storage.

“…For high-end markets, quality requirements are stringent and, apart from a desired light yellow color and the absence of defects, uniform shape and an adequate fruit size determine the marketability of the fruit (Johnson et al, 1997;Fukuda et al, 2013;Schulze et al, 2013). During post-harvest handling, quality control takes place, which, besides the elimination of defective fruits, includes the sorting according to size and shape.…”

“…Little information is available about dendritic spot disease of mango (Johnson & Hofman 2008), however it has been suggested that, the fungi which are responsible for anthracnose and stem end rot in mango are also involved in the occurrence of dendritic spot. As a range of fungi have been isolated from fruit infected with dendritic spot symptoms, no information is available to determine which fungus dominates in a particular mango growing area.…”

Fruit bagging experiments were carried out on Kensington Pride (KP) and R2E2 cultivars of mango to investigate the time of infection of dendritic spot and stem end rot. The fruit were bagged at four different growth stages. The results showed that fruit bagged at golf ball size which remained bagged until harvest had low incidence of dendritic spot and stem end rot.Higher incidence was observed in the fruit which were bagged close to harvest and the unbagged control fruit. It was concluded from the results that pathogens invade the fruit at an early growth stage and fruit protection at this stage of growth can help in minimizing postharvest disease incidence.The effect of conventional and improved orchard practices on the management of anthracnose and stem end rot was also studied. The experiment was carried out in Pakistan.Three districts of Punjab province of Pakistan were selected for the study. The fruit of Chaunsa cultivar of mango were collected from growers" conventional practice blocks and ASLP (Agriculture Sector Linkages Program) improved practice blocks. In the conventional practice blocks, there was irregular application of foliar and pesticides sprays, non-consistent use of fertilizers with a minimum use of cultural practices such as irrigation, pruning, weeding and soil nutrition analysis, use of recommended foliar sprays of fungicides for disease management at different fruit growth stages, pest management and nutrient management by annual application of NPK. Whereas, the improved practice blocks were maintained by cultural practices. A low incidence of anthracnose and stem end rot was observed in the fruit which was collected from the ASLP improved practice blocks as iii compared to the incidence observed in the fruit collected from the conventional practices blocks.Postharvest application of exogenous ethylene on mature fruit to induce uniform skin colour and ripening and hot fungicide dips to minimize postharvest disease incidence are common practices used by Australian mango growers. Early fruit ripening facilitated by exogenous ethylene is helpful in early fruit marketability, but it can result in higher disease incidence in case of prolonged fruit storage or higher fruit storage temperature. The effect of exogenous ethylene and hot fungicide dip with fludioxonil was investigated when both treatments were applied on the fruit alone and in combination with each other. The results showed that the application of exogenous ethylene alone caused higher incidence of dendritic spot and stem end rot when the fruit received frequent rainfall during the growing season. This higher incidence of both dendritic spot and stem end rot could also be because of accelerated fruit ripening and decline in fruit resistance. But, when low or no rainfall was received during the season, a low incidence of dendritic spot and stem end rot was observed when the exogenous ethylene was applied on the mature fruit. Fruit hot-dipped in the fungicide fludioxonil followed by the exogenous ethylene had zero to minimum inciden...
