Estudo de liberação do Rincoforol adsorvido em carvão ativado do endocarpo do coco de dendê

ABSTRACT: Among the methods of controlling the spread of red ring disease, the use of pheromones associated with food traps has been shown to be very efficient in capturing the pest insect. The pheromone used is called Rincoforol and is available in microtubes. Studies are under development to apply the capture agent to solid matrices. In this context, the present work was carried out in order to evaluate the adsorptive capacity of the activated carbon of the palm oil endocarp in the incorporation of Rincoforol for controlled release of pheromone in the field. For this, a complete experimental planning (23) was carried out in order to evaluate the influence of the use of stabilizer with the pheromone, the granulometry of activated carbon and the number of holes in the sachet in the release process, obtaining in response to mass loss. It was found that the condition that favors the controlled release of the pheromone, when compared to the release made in eppendorf, was the use of formulated Rincoforol (with stabilizer) adsorbed on charcoal with smaller particle size (35 <ᴓ <28 mesh) and sachet with 5 holes, a condition found in experiment number 3, which showed less loss of mass.
