Management of Lethal wilt disease in oil palm in areas with high incidence
Lethal wilt disease (ML for its name in Spanish) in oil is an endemic disease in Colombia, where its importance is not only related to more than 1000 ha eradicated in the East Zone between 1994 and 2010 but on his rapid spread toward other oil palm zones. The management practices implemented in the affected states have been detection and eradication of infected palms, as well as the control of grasses and the establishment of other cover crops, but these practices have not been enough to reducing the dissemination of the pathogen responsible of this disease. In the development of an integrated control program for ML, Cenipalma developed a plan that included the results on the research with its insect vector, the incubation period of the pathogen in the palm, the effect of agronomic practices and epidemiological studies. This work evaluated the management program i an area with a development rate above 0.030 year-1, that included detection and opportune eradication of affected palms, grasses and insect control, using efficient molecules. With a simulation model it was compared the development of the disease in the absence of the control measures.The results indicated that when the control measures were implemented according to the program at regional level, it was possible to reduce the number of cases of palms with ML between 30.8 and 98.9%, compared with the results where the management was implemented locally, where there was not a response to the control measures, because there was an increase from 29.2 to 59.9 in the number of diseased palms due to the inoculum carried by insects coming from neighboring infected fields with high inoculums potential. These results indicated that it is possible to control lethal wilt disease in oil palm when an integrated management program is implemented at regional level.

La Marchitez letal (ML) de la palma de aceite es una enfermedad endémica en Colombia; su importancia no sólo radica en las más de1.000 ha erradicadas en la Zona Oriental entre 1994 y 2010, sino en su rápida diseminación hacia otras zonas palmeras. Las prácticas de manejo realizadas en las plantaciones afectadas se han basado en la detección y erradicación de las palmas infectadas, el control de especies gramíneas y el establecimiento de coberturas; sin embargo, estas medidas por sí solas no han impactado satisfactoriamente la diseminación del patógeno responsable de la enfermedad. En el desarrollo de un programa integrado de control de la ML, Cenipalma diseñó un plan de manejo que incluye conocimiento sobre la presencia del vector, el periodo de incubación del patógeno en la palma, el efecto de las labores de manejo agronómico y la epidemiología de la enfermedad. En esta investigación se evaluó el plan de manejo en una zona afectada por la ML y con una tasa de desarrollo superior a 0,030 unidades año-1, el programa consistió en detección y erradicación oportuna de las palmas afectadas, control de gramíneas y del insecto vector usando moléculas eficientes. Mediante un modelo de estimación se comparó el avance de la enfermedad en ausencia de estas prácticas. Los resultados obtenidos mostraron que los manejos realizados durante los meses indicados y a nivel regional, permitieron reducir el desarrollo de la ML entre 30,8% y 98,8%, mientras que cuando el programa fue implementado de manera local, no hubo respuesta de las medidas de manejo y, por el contrario, la velocidad de desarrollo de la enfermedad se incrementó entre 29,2 y 59,9% como resultado del alto potencial de inóculo en lotes vecinos. También indicaron que es posible controlar la ML sí se implementan en forma integral todas las medidas de manejo propuestas mediante un enfoque regional.
