Aplicación de extracto vegetal del ají mediante endoterapia para el control de Tetranychus urticae en el cultivo de babaco (Vasconcellea x heilbornii)

Abstract

Babaco is an endemic fruit of Ecuador and has economic importance at the national level. Therefore, in the search for alternatives that allow a pesticide-free crop, it was proposed to evaluate the efficiency of the chili extract through the endotherapy technique for the control of Tetranychus urticae in babaco (Vasconcellea heilbornii). Capsaicin is one of the organic components that has presented greater efficiency in pest control and is easily obtained, for this work dehydrated chili was used in aqueous solution which was then filtered. Completely randomized experiment of 32 a control with three repetitions was proposed in an already established crop of 11 months, where 30 babaco plants were evaluated and in each experimental unit 3 leaf samples were taken at different heights. It was applied in 20 ml syringes and absorption was recorded daily, which was 4 ml maximum. Likewise, in the treatments there was a mortality of 96.8% compared to the control which was 11.7%. As a result the application of natural extract by means of endotherapy presented satisfactory effects for the control of mites.
