The major export variety is Cavendish, and is mainly handled by multinational corporations. Crown end rot (CER) of bananas is a post-harvest disease that develops as the fruit is being stored and ripened in the marketing chain. II Corso di dottorato in: Chimica, biochimica ed ecologia degli antiparassitari. Crown rot is a disease caused by a soil-borne fungus which can survive in the soil indefinitely. In most banana-growing areas, crown rot is principally controlled by postharvest fungicide treatments, but alternative control methods are being sought because of: (1) the emergence of resistance to some commonly used fungicides; (2) environmental problems linked to dumping of fungicide mixtures used at packing stations; and (3) consumer aversion to chemical residues in food. On the stem ends of the fruit: blackening and rotting of the cut or otherwise damaged ends of the fingers where they were previously attached to the crown of the bunch (Photo 1).

In severe cases, the inner leaves of the crown first turn yellow, then brown and finally die. Additional Information. Abstract. The content of this review is divided into two parts. Among these, crown rot is the most serious post-harvest disease in commercial bananas worldwide, as the disease shortens the storage life and spoils the appearance of fruit (Ranasinghe et al., 2003). Usually invisible when the fruits are packed for transportation from tropical countries to distant destinations, disease symptoms occur during shipment, ripening, and storage. Usually invisible when the fruits are packed for transportation from tropical countries to distant destinations, disease symptoms occur during shipment, ripening, and storage. Rotting is most noticeable if transport time exceeds 7 days 19. CROWN ROT. It may reach the pedicel and even the banana pulp when crown rot is severe.

Crow n rot affects export banan as in all banana-producing coun- tries and is considered to be one of the main ex port banana post- harvest diseases (62,85). A wide range of organisms are involved in crown rot of bananas but Colletotrichum musae is frequently considered as the most commonly isolated fungus and the most pathogenic one. The product must be applied by dipping the crown in a solution containing SANI CR and water in equal parts, always after the last cut to be made to the bunch. 3 patents. The physiological component is defined as the sensitivity of the fruits to crown rot, and the parasitic component reflects the capacity of the parasitic complex to induce a level of disease. Crown rot disease is considered to be the main export banana postharvest disease (Reyes et al., 1998, Krauss and Johanson, 2000) and it affects export bananas in all banana-producing countries. Introduction Banana is one of the major sources of income and foreign exchange earnings which accounts for about 9% of total agricultural exports of the Philippines. Keywords: organic banana; crown rot; vacuum packaging; sodium bicarbonate 1. This disease, characterized by rot and necrosis, affects tissues joining the fingers with each other, called the crown. Banana plant's resistance to biotic stress has been previously correlated to its phenolic content; it is hypothesized that the crown's phenolic content may influence the fruit's susceptibility.

BANANA CROWN ROT Exported bananas are subjected to various phytosanitary constraints throughout the production chain and these alter fruit marketability. Aphids and mites can attack bananas and suck sap from leaves; look for clusters of aphids on the stems and under leaves; knock them off with a strong spray of water or spray with insecticidal soap. The rot may spread into the crown during transportation 3. Symptom of Crown Rot of Banana 1. Crown end rot (CER) of bananas is a serious cause of post-harvest quality loss for banana fruit. Banana .

Crown rot affects tissues of the so-called ‘crown’, which unites the peduncles (Fig. Crown rot, the most important postharvest disease of banana, is a syndrome caused by several fungi including Lasiodiplodia theobromae (Ogawa, 1970, Johanson and Blazquez, 1992), Colletotrichum musae (Finlay and Brown, 1993), Thielaviopsis paradoxa (Alvindia et al., 2002), and the Fusarium spp. This fungal disease is often favored by wet conditions and heavy soils. The frequency of organisms associated with crown rot of banana (PCB) in Costa Rica was compared in two banana production systems. Banana susceptibility to crown rot is influenced by many biotic and abiotic preharvest factors, which include source‐sink (So‐Si) ratio modifications through trimming of leaves and fruit. Crown rot of banana. It may reach the pedicel and even the banana pulp when crown rot is severe. Crown rot is a complex disease that affects export bananas in all banana-producing countries. Fruit quality potential depends on both a physiological and a parasitic component, both of which depend on agrotechnic and pedoclimatic factors of the crop production area. The organisms isolated were similar to those previously described by other authors and were common to the two systems (integrated and organic), but the frequency of recovery, overall, was higher in the integrated system. ...
