Causes of postharvest losses of mango at the wholesale market level in Costa Rica.

ABSTRACT

Mango fruit were sampled biweekly at the CENADA wholesale market, the largest in Costa Rica, during the 1990 season. Disease incidence was 64.6% for anthracnose (Colletotrichum gloeosporioides [Glomerella cingulata]), 7.2% for stem-end rot (Lasiodiplodia (Botryodiplodia) theobromae) and 5.2% for fruit rot (Aspergillus sp.). Fruit flies affected 15.8% of fruit. Sapburn was found in 37.5% of fruit, and 48.7% of fruits were mechanically injured. Anthracnose incidence was 14.1% in the dry season (Mar.-Apr.) and 84.4% during the rainy season (May-Jul.). Fruit fly damage was found in 2.5 and 21.1% of fruit in the dry and rainy seasons, respectively. A very low incidence of rots caused by Hendersonula sp., Coniothyrium sp., Pestalotia sp. and Erwinia sp. was found.
