Control preventivo de la enfermedad de pudrición seca en el estípite de palma de aceite Elaies guineensis Jacq. En la finca Cañaguatera del municipio de Tibú, Norte de Santander.

Abstract

With this field practice work, preventive control alternatives were achieved in the central area ofthe department of Norte Santander, the cultivation of Oil Palm, one of the frequent diseases is presented, a type of basal rot of the stipe, dry basal rot. (PBS), the causal agent identified as Ceratocystis paradoxa (Dade) Moreau. Consequently, it is a phytosanitary problem that affects the state of health of the crop of the Cañaguatera farm, palm losses occur, affecting production and yield. Due to this, the objective that was raised to treat this disease was based on the preventive control of the disease management, describing the symptomatology of the cases of the basal rot of the stipe in 10 hectares of palms, an application of Geopalnorte was used. To georeference the cases found on the map, as prevention, in order to counteract these diseases, an efficient biological control of antagonistic fungi of Trichoderma harzianum and Trichoderma koningii was implemented where an organic product from Biopalm Mineral was applied. In this property, the impact of the incidence remained stable at 1.4% during the first month, where the applications were made to the six adjacent palms of the patient, with a frequency of 8 days. A fungicide against the disease (PBS) was applied to the diseased palm. The result showed us the inoculation of the beneficial fungus after the three applications. Preventive management of these antagonistic fungi is the solution to mitigate this limitation, for palm growers it has been a successful alternative to sustain production and productivity.
