Abstract
AbstractMango fruits' quality, marketability, and shelf life are significantly influenced by postharvest decay. Mango fruit disease development during storage is inhibited by fungicides. The objective of this investigation was to assess the relative effectiveness of two fungicides, azoxystrobin 18.2% + difenoconazole 11.4% SC and hexaconazole 5% SC, in mitigating postharvest deterioration of mango cv. ‘Langra’ during low temperature storage. Three pathogens were found associated with postharvest decay of mango, i.e. Colletotrichum gloeosporioides, Alternaria alternata, and Penicillium expansum. In comparison to untreated ones, the preharvest application of fungicide treatments provided noticeably better disease control. The foliar application of azoxystrobin 18.2% + difenoconazole 11.4% SC (0.1%) 15 days before the harvesting of fruits significantly improved fruit firmness, soluble solid content, titratable acidity, reduced the disease incidence, percentage disease index, and lesion diameter followed by the application of hexaconazole 5% SC (0.1%) compared to the control. Furthermore, it was found that pre-harvest fungicide spraying of azoxystrobin 18.2% + difenoconazole 11.4% SC (0.1%) was an effective treatment for lowering postharvest deterioration and enhancing the physio-chemical characteristics of mango fruits during low-temperature storage.
