Abstract
La sigatoka negra, causada por Mycosphaerella fijiensis, representa uno de los principales desafíos fitosanitarios en la producción mundial de banano, causando pérdidas económicas significativas que pueden alcanzar hasta el cincuenta por ciento del rendimiento en plantaciones comerciales. El objetivo del estudio es evaluar la eficacia del extracto de canela (Cinnacontrol) en el control de la sigatoka negra en plantaciones bananeras de la provincia de Los Ríos. El enfoque es cuantitativo, tipo experimental aplicado, con diseño en bloques completos al azar. Se evaluaron tres tratamientos basados en Cinnacontrol a diferentes dosis en comparación con un testigo sin aplicación. El estudio se desarrolló durante seis meses en tres fincas productoras de banano, monitoreando semanalmente la incidencia y severidad de la enfermedad mediante la escala de Gauhl modificada por Stover. Los resultados indican que los tratamientos con Cinnacontrol demostraron eficacia significativa en la reducción de la severidad de la sigatoka negra. El análisis estadístico reveló diferencias altamente significativas entre los tratamientos (p menor que cero puntos cero uno), con mejor respuesta en las fincas evaluadas durante los períodos de verano y preinvierno. Se concluye que el Cinnacontrol se constituye como una alternativa viable y sostenible para el manejo integrado de Mycosphaerella fijiensis en banano, ofreciendo una herramienta eficaz que contribuye al mantenimiento de un número adecuado de hojas funcionales y reduce la dependencia de fungicidas sintéticos.
Black sigatoka, caused by Mycosphaerella fijiensis, represents one of the main phytosanitary challenges in global banana production, causing significant economic losses that can reach up to 50% of yields in commercial plantations. The objective of this study is to evaluate the efficacy of cinnamon extract (Cinnacontrol) in controlling black sigatoka in banana plantations in Los Ríos province. The approach is quantitative, applied experimental, with a randomized complete block design. Three Cinnacontrol-based treatments were evaluated at different doses compared to a control without application. The study was conducted over six months on three banana farms, with weekly monitoring of disease incidence and severity using the Stover-modified Gauhl scale. The results indicate that Cinnacontrol treatments demonstrated significant efficacy in reducing the severity of black sigatoka. Statistical analysis revealed highly significant differences between treatments (p less than 0.01), with the best response on farms evaluated during the summer and pre-winter periods. It is concluded that Cinnacontrol is a viable and sustainable alternative for the integrated management of Mycosphaerella fijiensis in banana, offering an effective tool that contributes to maintaining an adequate number of functional leaves and reduces dependence on synthetic fungicides.
