Biopreparados para el control de enfermedades foliares de fresa, Pamplona, Colombia, aun una solución parcial

Abstract

Resumen Objetivo. El trabajo tuvo como objetivo determinar la eficacia de seis biopreparados locales para el control de las enfermedades foliares del cultivo de la fresa. Materiales y métodos. Se condujo un experimento en la finca Camacho del municipio de Pamplona Norte de Santander, Colombia. Se utilizó un diseño de bloques al azar con nueve tratamientos, seis biopreparados locales, tres testigos (una saneado, uno sin sanear y un químico). Resultados. Se identificaron como enfermedades foliares más importantes de la fresa a Ramularia tulasnei, Colletotrichum sp., Botrytis cinerea y Xanthomonas fragariae. Los biopreparados Caldo rizósfera y Microorganismos Eficientes (ME) resultaros superiores al tratamiento químico con mancozeb para la mancha por Ramularia. Los bioproductos Caldo Rizósfera y ME mostraron resultados similares que el control químico contra., la pudrición por Botrytis, la mancha por Xanthomonas, y la antracnosis en hojas, flores y frutos, pero los niveles de incidencia de esta enfermedad estuvieron entre 46 y 55 % en flores y entre 56 y 63 % en frutos. Conclusiones. Los biopreparados Caldo Rizósfera y ME resultaros superiores al tratamiento químico con Dithane para mantener a la mancha por Ramularia en niveles de severidad aceptables, al igual que a la mancha bacteriana y la pudrición por Botrytis y resultaron similares que el control químico contra la antracnosis en hojas, flores y frutos, sin embargo, los niveles de incidencia en flores y frutos de la antracnosis no son los deseados, amenazando la rentabilidad del agricultor.
