CASTANEDA SANCHEZ, Darío Antonio and ESPINOSA ORREGO, John Alexander. BEHAVIOR AND IMPACT OF THE MOKO DISEASE IN THE URABÁ REGION ( COLOMBIA ), DURING THE PAST 35 YEARS AND PROPOSAL OF AN RISK INDEX FOR THE DISEASE. Rev.Fac.Nal.Agr.Medellín [online]. 2005, vol.58, n.1, pp. 2587-2599. ISSN 0304-2847.
Although, moko disease has been monitored based upon the number of the farms affected, it is shown that this is not a recommended indicator for disease management, because it does not reflect the real condition and the risk it represents according to its distribution. A more precise indicator is based on the number of foci. The historic mean percentage for the moko disease according to this indicator is 0,06 % for the Urabá region, which equates to an annual average destruction of 589,8 foci. In area, the mean annual destruction was 16,5 ha for a total of 611 ha registered in 33 years, representing direct evidence of the destructive capacity and of the economic impact of the disease. Therefore, a risk index is proposed for the disease, estimated on the product of the relationships between the infected area / the total area, and between the infected lots / total lots, which can easily be implemented at any farm in the banana or plantain sector.
