Evaluación de cinco acaricidas para el control de Oligonychus sp. y Tetranychus sp. en el cultivo de Selenicereus undatus en el cantón Palora

Abstract

In the Amazon region of Ecuador, specifically in the Palora Canton, yellow pitahaya is produced. It is an important crop because the demand for this fruit is high and it is for export purposes, which makes it profitable. This research aims to find an efficient alternative for the management/control of Olygonichus spp and Tetranychus spp mites, because these arthropods are currently considered a true phytosanitary problem in crops. The present investigation was carried out in a commercial pitahaya farm located in the Palora Canton belonging to the province of Morona Santiago, through which the effect of five acaricides was evaluated against a control, the treatments applied did not show statistically significant differences. However, it should be noted that the acaricide Cyenopyrafen was the one that gave the best results in the control of eggs in the fifth week of application (MED=91.5), and the acaricide Bifenazate best controlled the adult mite populations in the fifth week (MED = fifty). Regarding cost, it was determined that the best in both effectiveness and value is the acaricide Bifenazate, with a high percentage of control with respect to the other treatments.
