Resumen
La investigación se realizó en el año 2017, en la Hacienda bananera “La
Perseverancia”, provincia del Guayas. Con el objetivo general de desarrollar
y adaptar tecnologías para el control de la pudrición de la corona de la mano
del banano (Musa paradisiaca L.) variedad William, a fin de mejorar la
productividad y calidad de la fruta, preservando el medio ambiente. Se empleó
el diseño completamente al azar, con arreglo factorial de 3 x 2 + 1. Se
probaron dos fungicidas de origen natural (Timorex Gold y Max Fun) y uno
químico (Fungaflor 75) combinados con dos dosis de aplicación, más un
testigo absoluto, al cual no se le aplicó nada. Se concluye: a) el fungicida de
origen natural Max Fun, fue quien mejor controló el crecimiento del moho en
la corona de la mano de banano con 16,7 %, b) en las variables incidencia de
la pudrición de la corona, severidad de la infección en la corona e infección
del pedúnculo, no destacó ninguno de los fungicidas en su control, por lo que
se puede sustituir el fungicida químico por los de origen natural, c) Las dosis
de aplicación 1,5 l/200 l de agua en Timorex Gold, 3,0 g en 40 l de agua en
Fungaflor 75 (PS) y 2,0 l/200 l de agua en Max Fun, presentaron mejor control
de la pudrición de la corona de la mano del banano variedad William, y d) los
tratamientos donde se aplicaron los fungicidas, fueron menos afectados por
la pudrición de la corona de la mano del banano variedad William.
He investigation was carried out in 2017, at the Banana Farm "La Perseverancia", province of Guayas. With the general objective of developing and adapting technologies for the control of crown rot from the hand of banana (Musa paradisiaca L.) variety William, in order to improve the productivity and quality of the fruit, preserving the environment. The completely random design was used, with a factorial arrangement of 3 x 2 + 1. Two fungicides of natural origin (Timorex Gold and Max Fun) and one chemical (Fungaflor 75) combined with two application doses, plus an absolute control, were tested. to which nothing was applied. It is concluded: a) the fungicide of natural origin Max Fun, was the one that better controlled the growth of the mold in the crown of the banana hand with 16.7%, b) in the variables incidence of crown rot, severity of the infection in the crown and infection of the peduncle, did not highlight any of the fungicides in its control, so that the chemical fungicide can be replaced by those of natural origin, c) Application doses 1.5 l / 200 l of water in Timorex Gold, 3.0 g in 40 l of water in Fungaflor 75 (PsS) and 2.0 l / 200 l of water in Max Fun, presented better control of the crown rot of the hand of banana variety William, and d ) the treatments where the fungicides were applied, were less affected by the rotting of the crown of the banana variety William.
