Botryosphaeria (Anamorphs Fusicoccum and Dothiorella), Diaporthe (Anamorphs Phomopsis spp.) and Lasiodiplodia: infection and defence.

Along with anthracnose, stem end rots (SER) caused by Lasiodiplodia theobromae and the anamorphs of Botryosphaeria and Diaporthe, are major causes of postharvest loss in many fruit. Infection of fruit by SER pathogens occurs by endophytic colonisation of the pedicel or via wounds and other receptive tissues. Water stress and defoliation of the host, microbial competition, and the production of phytotoxins and insect attractants by the pathogens can influence their inoculum potential. Following infection, abscission zone barriers and antifungal compounds may restrict invasion until the fruit ripen or senesce. The regulation, manipulation or enhancement of host, pathogen and ecological factors all offer scope for preventing or delaying infection and reducing the incidence, onset, and severity of stem end rot. The role of these factors, and the potential for manipulating them to control stem end rot diseases, is reviewed.
