Race 2 attacks clones of the Bluggoe subgroup (<span class="CharOverride-6">Musa</span> ABB); and race 4, through its tropical and subtropical variants, attacks all Cavendish clones, and those susceptible to race 1 and race 2. There are no natural clones that can replace the current ones. Tropical race 4 (R4T), has spread in different continents, causing multimillion dollar losses, with extreme limitations for its eradication, and recently is a cause for concern in Latin American and Caribbean (LAC) countries, due to its recent report in the Colombian Guajira. <strong><span class="CharOverride-2">Conclusion. </span></strong>The deficient control, and ignorance of thr traits of the pathogen and the disease, make necessary the development of research for its early diagnosis, management strategies, education measures, and / or promotion of contingency plans. Recently it was detected in Colombia, which implies high risk for the rest of the countries of the LAC region (with emphasis on Ecuador, Panama, and Venezuela), due to the constant flow of people (including tourists) and commercial transactions, being necessary in a way it is imperative to review the risk analysis in this new scenario.</p> ER -
