Management options for bud rot in oil palm in areas with low disease occurrences
As a result of the research activities on alternatives for the handling of the bud rot (PC for its name in Spanish) of the oil palm, there are several recommendations. The process is started with the early diagnosis of the disease, using a severity scale, based on the symptoms in the younger spear leaf with more than 30 cm in length, developed for nursery palms. In older palms there is evaluated the damage of the tips of some leaflets in the younger leaf (bite), that is a good indicator in palms of any age, that promote the need to inspect the spears, to confirm the diagnosis, when this symptoms are observed. As a reaction to the presence of early stages of PC, it is recommended the elimination of the affected tissue and in more advanced cases, the eradication of the diseased palm. The elimination of the affected tissue is complemented with the treatment with an insecticide and a mixture of fungicides and bactericides applied to the exposed tissue, the first to prevent the attack of insects and the last to protect against microorganisms that might find the opportunity to penetrate throughout the wounds produced. It is necessary to follow up the development of the treated palms to verify the emission of new healthy leaves and to repeat the treatment when needed. Besides there is a spray program of insecticide, bactericides and fungicides, to the base of the spear leaf of the treated palms and of the surrounding ones, to control different pathogens and insects associated with the bud rot. This work is complemented with the flaming of the areas exposed during the surgery, in cases in which this goes deeper in the bud area, to control the reproductive structures of different microorganisms.

Como resultado de las investigaciones adelantadas sobre alternativas de manejo de la Pudrición del cogollo (PC) de la Palma de aceite, en este artículo se propone una serie de recomendaciones. El proceso se inicia con un diagnóstico temprano de la enfermedad, utilizando la evaluación de los síntomas en la flecha más joven con más de 30 cm de largo, según la Escala de severidad desarrollada para palmas de vivero. En palmas de mayor edad se evalúa el daño en los extremos de los folíolos de la hoja más joven (mordisco), siendo éste un indicador apropiado para palmas de cualquier edad, que genera la necesidad de hacer la inspección de las flechas para confirmar el diagnóstico en los casos en los cuales se presenta. Como reacción a la presencia de los estados tempranos de la PC, se recomienda la eliminación del tejido afectado y, en los casos más avanzados, la erradicación de la palma enferma. Esta práctica de eliminación del tejido enfermo se complementa con un tratamiento con insecticida y una mezcla de fungicida-bactericida, aplicada al tejido expuesto; el primero, para prevenir el ataque de insectos, y la última, para proteger contra los microorganismos que puedan encontrar la oportunidad de penetrar por las heridas realizadas. Se debe hacer un seguimiento a las palmas tratadas para verificar la emisión de hojas sanas; en caso contrario se debe repetir la operación. Además se implementa un programa de aspersiones de insecticida, fungicidas y bactericidas, dirigidas a la base de las flechas, tanto de las palmas tratadas como de sus vecinas, con una serie de productos que permitan el control de una gama amplia de microorganismos patógenos e insectos asociados con la PC. El trabajo es complementado con un flameo de la zona, en las cirugías más profundas, para controlar estructuras reproductivas de diferentes microorganismos.
