Evaluación del efecto de controles biológicos contra la marchitez letal y su vector (Haplaxius crudus), en cultivo de palma de aceite (Elaeis guineensis Jacq), Palmera la Fortuna, Vistahermosa, Meta.

Abstract

A very current problem in the cultivation of oil palm (Elaeis guineensis Jacq.) Are the diseases that can present considerable losses in harvest, among the main ones is lethal wilt. The objective of the research was to evaluate the effect of efficient microorganisms (EM) and their reproduction against Lethal Wilt and its vector (Haplaxius crudus) in oil palm cultivation (Elaeis guineensis Jacq), developed in the La Fortuna palm tree, Vistahermosa, Goal. The methodology was structured in three phases; For the first phase, a characterization of the final concentration of the multiplication of efficient microorganisms to be used in the La Fortuna palm was carried out from a stock concentration of efficient microorganisms; In a second phase, a commercial formulation of EM was evaluated in the field, for which a completely randomized experimental design was used using two frequencies of application of EM (14 and 28 days) as treatments and a control with 4 plots as repetitions. The efficacy of the EMs was compared by evaluating the effect on the disease, the vector every 14 days and for the third phase, the evaluation of the influence of efficient microorganisms on the development of the morphometric variables of the palm plants was carried out. The practice of biological control with efficient microorganisms for the management of the lethal wilt disease did not show statistical difference for the control of the disease, nor was there a significant difference for the number and length of leaves until week 4, which presented a statistical deference and The plants did not respond quickly to the applications, however, the results are encouraging as the research time was too short to ensure that the efficient microorganisms had a lasting effect at the frequencies that were being applied against the lethal wilt and the variables morphometric.
