Losses of apple fruit (cv. Cripps pink) caused by fungal diseases during storage

Apple (Malus domestica Borkh.) is the most significant fruit species in Croatia. Therefore, a study was initiated to determine causal agents of apple fruit cv. Cripps Pink postharvest diseases and losses during storage in ULO (Ultra Low Oxygen) conditions. Fungi were determined based on symptoms on rotten apple fruit and morphological features in pure culture. Prevalent fungi determined in this study were: Penicillium spp., Neofabraea spp. and Botrytis spp. Incidence of other genera Fusarium, Colletotrichum, Alternaria and Botryosphaeria was determined at lower frequencies. Economic losses were estimated based on weight loss per one tone with average wholesale market price of one kilo of apple cv. Cripps Pink. Both disease incidence and economic loss were significantly increased with prolongation of storage period. Such results pointed out significance of postharvest diseases and their potential to cause substantial yield and economic losses.
