Abstract : In Brazil, the main diseases of mango in the postharvest phase are anthracnose and stem rot, caused by Colletotrichum and Botryosphaeriaceae, respectively. Epidemiology and management of anthracnose and stem rot of mango are investigated for many years, but obtaining good levels of control of these diseases is still a challenge. The central issue is that in recent years several new species of Colletotrichum and Botryosphaeriaceae pathogens have been detected on mango, leading to doubt whether these species are equally sensitive when considering the epidemiological aspects and management measures adopted, such as use of fungicides. It is also important to establish whether these new pathogens have host specificity or a broad host range and if there is variability in their virulence depending on variety and environmental conditions. This paper indicates that knowledge of these aspects related to biology and epidemiology of the species that infect mango is essential for the development of management strategies. It is concluded that the effectiveness of the measures adopted for the management of stem rot and anthracnose may be variable according to the predominant pathogen species. Therefore, precise identification of species causing the diseases, analysis of the prevalence and distribution of these species as well as investigation on the reaction of the predominant species to different control measures are suggested.
