Respuesta fisiológica de la palma de aceite a la aplicación de herbicidas al plato
Weeds are pioneer plants of secondary succession that affect the crop development and production by competing for water, light and nutrients. In oil palm crops, weed control is carried out between rows, plot borders, ditches, and circles around the palm trunks, using physical (machetes or scythe) or chemical (herbicides) methods. There are few reports about the effects of circle-weeding of palm circles with chemicals on the development of the plant and the crop; therefore, the objective of this study was to determine the effect of circle-weeding with active ingredients of herbicides on the physiology of oil palms in productive age. The effect of four herbicide applications during one year was evaluated: glufosinate ammonium, ametryn, haloxyfop, indaziflam, metsulfuron, fluazifop, fluroxypyr and glyphosate, applied on a circular area around OxG interspecific hybrid oil palms (Brasil x Djongo) planted in Paratebueno, Cundinamarca. Six and twelve months after the first application, the values of gas exchange, vegetative and reproductive growth were recorded. The physiological variables did not show significant differences due to the application of herbicides around the plant. Therefore, the responsible use of herbicides could be considered within an integrated weed management program.
