Wilting in banana plantations caused by the fungus Fusarium oxysporum f.sp. cubense has generated massive losses over the years. So far, the fungus consists of 4 races, being race 1 the one that caused 100% losses to the Gros Michel variety and for this reason the Cavendish hybrid was introduced (not susceptible to race 1). Today this cultivar is threatened by race 4 (tropical or subtropical). There is no effective treatment to destroy this particular race. Currently, an integrated management is being implemented with different strategies adapted to all kinds of situations in the banana areas. For these measures to be effective, whether for prevention or management, it is important to understand the epidemiology of this fungus. This literature review compiled information in order to understand the evolution that the fungus has had over the years, emphasize the impact generated by climatic and edaphological factors and state the different prevention and management strategies such as biosecurity, chemical, biological and varietal control. Each of these points contributes to improved management. Based on the information collected, it was concluded that the evolution of Fusarium oxysporum f.sp. cubense influences the severity of the Foc R4T attack and the dispersal process should be a prioritized factor, as well as the management and prevention techniques for decision making.
