The anthracnose is important disease in the pre an d postharvest phases. Several species of Colle- totrichum ( C. gloeosporioides, C. acutatum, C. musae e C. magn a ) are responsible for inciting this disease. The pathogen infects many fruit trees in tropical and t emperate regions, causing considerable damage and l oss in all phases of cultures. Characteristic symptoms are dar k necrotic lesions depressed, subcircular or angula r shaped, and there may be coalescing. Infections have a spec ial feature: the phenomenon of quiescence. This pro cess has important implications, particularly in post-harves t, because the damage from infections reflect only this phase. The intensity of the disease have been striking at temperatures from 24 to 28 °C and in the presence o f high relative humidity. The understanding of some aspect s of the biology of the pathogen (the process of qu ies- cence) and the epidemiology of the disease is cruci al, since much has not yet been fully clarified, es pecially when the aim is to achieve sustainable management.
