Resumen
Este estudio evaluó el efecto del bioinsumo Sáferbacter WP sobre la incidencia de las enfermedades moniliasis (Moniliophthora roreri) y pudrición parda (Phytophthora spp.) en cacao (Theobroma cacao L.). El ensayo se desarrolló entre marzo y octubre de 2025 en dos granjas experimentales de la Compañía Nacional de Chocolates ubicadas en Támesis (Antioquia) y San Vicente de Chucurí (Santander), bajo condiciones agroclimáticas contrastantes. Se utilizó un diseño de bloques completos al azar con tres tratamientos: Sáferbacter WP a 1,5 g·L⁻¹, Sáferbacter WP a 0,75 g·L⁻¹ y un control sin aplicación. Las variables principales evaluadas fueron el número de mazorcas afectadas por Moniliophthora roreri y Phytophthora spp. Los análisis estadísticos realizados en la granja La Nacional no evidenciaron diferencias significativas entre tratamientos, aunque sí se observaron diferencias entre bloques, sugiriendo una influencia importante de las condiciones microambientales sobre la incidencia de las enfermedades. En la granja Yariguíes, la disponibilidad limitada de frutos debido a una poda previa restringió la evaluación del efecto de los tratamientos. Los resultados indican que, bajo las condiciones estudiadas, no se detectó un efecto significativo del bioinsumo, aunque se recomienda continuar su evaluación durante períodos más prolongados.
This study evaluated the effect of the bioinput Sáferbacter WP on the incidence of frosty pod rot (Moniliophthora roreri) and brown pod rot (Phytophthora spp.) in cacao (Theobroma cacao L.). The experiment was conducted between March and October 2025 at two experimental farms of Compañía Nacional de Chocolates located in Támesis (Antioquia) and San Vicente de Chucurí (Santander), Colombia, under contrasting agroclimatic conditions. A randomized complete block design was implemented with three treatments: Sáferbacter WP at 1.5 g·L⁻¹, Sáferbacter WP at 0.75 g·L⁻¹, and an untreated control. The main variables evaluated were the number of pods affected by Moniliophthora roreri and Phytophthora spp. Statistical analyses conducted at La Nacional farm revealed no significant differences among treatments; however, significant differences were observed among blocks, suggesting a strong influence of local environmental conditions on disease incidence. At Yariguíes farm, the assessment was limited by low fruit availability resulting from a severe pruning event prior to trial establishment. Under the conditions evaluated, the bioinput did not show a significant effect on disease incidence. Nevertheless, longer evaluation periods are recommended to better determine its potential impact under field conditions.
