Summary

The disease known as Fusarium wilt is one of the most destructive plantain and banana crops in the world. It was initially described by Bancroft in Australia (1876) and the causative fungus by Smith (1910). In 1935 Wollenweber and Reinking determined that it was a variant of the Fusarium oxysporum fungus, later named as F. oxysporum f. sp. Cubense; currently four physiological races are known (R1, R2, R3 and R4). R1 destroyed more than 80,000 ha of the Gros Michel banana cultivar in the 1950s; it was replaced by resistant varieties of the Cavendish subgroup widely cultivated today. In the 1990s, Cavendish resistance was overcome by a new variant called Tropical Race 4 (TR4) in Taiwan, it has spread from there, putting the world production of plantain and banana at risk. On August 8, 2019, the Colombian Agricultural Institute (ICA) confirmed the presence of TR4 in banana crops in the department of La Guajira in Colombia, and initiated the contingency plan that included the eradication of 168 ha of bananas in the detection area, restrictions on the movement of musaceae plant material in this region, as well as epidemiological surveillance in the department and other plantain and banana producing areas in Colombia, among other activities. The objective of this seminar is to present some characteristics of the biology of the fungus and the epidemiology of the disease that explain the determining factors of its occurrence and why it represents a high risk for production and world and national food security, including coffee growing areas in Colombia. This information was used in a training program for plantain and banana producers from 25 departments in Colombia carried out by Cenicafé in an agreement between the FNC and the ICA in 2019.
