| dc.description | Bananas are one of the main export crops, as well as one of the largest generators of jobs and foreign exchange that Ecuador has. This fruit is in high demand in other continents for its flavor and high quality. There are some factors that influence banana production, such as black leaf streak disease caused by the fungus (Mycosphaerella fijiensis) that drastically attacks the foliar tissue of the crop, thus causing losses and generating a higher production cost to combat said fungus. On the farm La Rabuda, it is considered that this pathogen reduces photosynthesis and affects the normal growth of the plant. In the absence of effective control, it can reduce bunch weight by 50% and can cause 100% production losses due to poor fruit quality. In the last 2 years the farm has carried out a variety of cultural tasks and aerial fumigations that have managed to control and prevent black sigatoka, currently there is no visual evidence of damage greater than 50% in the plantation. In 2018 there was a greater infection of damage caused by this disease, which caused the quality of the fruit to decrease in size and thickness. On the other hand, in 2019 there were no problems due to additional security controls being implemented, due to the threat of the disease fusarium oxysporum race 4 that was found in Colombia. | es_ES |

| dc.description.abstract | El banano es uno de los principales cultivos de exportación, así como también uno de los mayores generadores de empleos y divisas que tiene el Ecuador. Esta fruta es muy demandada en otros continentes por su sabor y su alta calidad. Existen algunos factores que influyen en la producción de banano como lo es la sigatoka negra causado por el hongo (Mycosphaerella fijiensis) que ataca drásticamente al tejido foliar del cultivo, causando así perdidas y generando un mayor costo de producción para combatir dicho hongo. En la hacienda la Rabuda se considera que este patógeno disminuye la fotosíntesis y afecta el crecimiento normal de la planta. En ausencia de un control efectivo puede reducir el peso del racimo en un 50% y puede causar perdidas de producción del 100% debido a la mala calidad de la fruta. En los últimos 2 años la hacienda a realizado una variedad de labores culturales y fumigaciones aéreas que han logrado controlar y prevenir la sigatoka negra, en la actualidad no se evidencia visualmente daños mayores al 50% en la plantación. En el año 2018 hubo una mayor infección de daño causada por esta enfermedad lo cual ocasionó que la calidad de la fruta disminuya en tamaño y grosor. En cambio, en el 2019 no se presentaron problemas debido que adicionalmente se implementaron más controles de seguridad, debido a la amenaza de la enfermedad fusarium oxysporum raza 4 que se encontraba en Colombia. | es_ES |
