| dc.description | Sugar cane, belonging to the Poaceae family, is the source of sugar, one of the most consumed foods in the world. The objective set for this work was: Describe the phytoparasitic nematodes in sugarcane cultivation in Ecuador. A qualitative and descriptive approach to the methodology was developed, and information was collected from up-to-date sources for the creation of this report. Websites, journals, scientific papers, online library resources, and any relevant reference materials to advance this study. The results obtained regarding phytoparasitic nematodes in sugarcane are Pratylenchus spp. and Meloidogyne spp. In Ecuador, nematodes damage the root system of sugarcane by injecting toxins, which causes deformations (Meloidogyne spp) and necrosis (Pratylenchus spp). Damage not only reduces crop production, but also reduces its quality; Pratylenchus spp. It lives inside the roots and emerges when the root is completely decomposed, either as a consequence of the damage caused or simply to migrate to other roots, causing damage through the cortical tissue by breaking the cell wall; carbofuran-based chemical nematicides at doses of 5 kgha are usually the most effective way to control high levels of Meloidogyne spp. It is concluded that in Ecuador the presence of phytoparasitic nematodes damages the root system of sugarcane by injecting toxins, which causes deformations (Meloidogyne spp) and necrosis (Pratylenchus spp) and therefore decreases crop yield. | es_ES |

| dc.description.abstract | La caña de azúcar, perteneciente a la familia Poaceae, es la fuente del azúcar, uno de los alimentos más consumidos en el mundo. El objetivo planteado para este trabajo fue: Describir los nemátodos fitoparásitos en el cultivo de la caña de azúcar en el Ecuador. Se desarrolló un enfoque cualitativo y descriptivo para la metodología, y se recopiló información de fuentes actualizadas para la creación de este informe. Sitios web, revistas, documentos científicos, recursos de bibliotecas en línea y cualquier material de referencia relevante para avanzar en este estudio. Los resultados obtenidos en cuanto a los nematodos fitoparásitos en caña de azúcar son Pratylenchus spp. y Meloidogyne spp. En el Ecuador los nemátodos dañan el sistema radicular de la caña de azúcar al inyectar toxinas, lo que causa deformaciones (Meloidogyne spp) y necrosis (Pratylenchus spp). Los daños no sólo reducen la producción de cultivos, sino que también reducen su calidad; Pratylenchus spp. vive en el interior de las raíces y emerge cuando la raíz está completamente descompuesta, ya sea como consecuencia del daño causado o simplemente para migrar a otras raíces, provocando daño a través del tejido cortical al romper la pared celular; los nematicidas químicos a base de carbofuran en dosis de 5 kgha suelen ser la forma más eficaz de controlar los niveles altos de Meloidogyne spp. Se concluye que en Ecuador la presencia de los nemátodos fitoparásitos daña el sistema radicular de la caña de azúcar al inyectar toxinas, lo que causa deformaciones (Meloidogyne spp) y necrosis (Pratylenchus spp) y por ende disminuye el rendimiento en el cultivo. | es_ES |
