| dc.description | In Ecuador, mainly in the coastal zone, hard yellow corn is one of the most important products since its supply frames different activities in the agricultural sector, this being one of the transitory crops mostly planted by small, medium and large agricultural producers. However, among the parameters that affect crop production are the main diseases Leaf blight (Exserohilum turcicum), Asphalt spot (Phyllachora maydis), Common rust (Puccinia maydis), Ear rot (Diploidia zeae), Ear rot stem (Fusarium graminearum) and red ribbon (Spiroplasma kunkelli), whose inhibitory activity has caused loss, since their symptoms and affectation occur in the reproductive stage. In the research, the method with a qualitative approach and descriptive scope was used. Furthermore, to prepare this document, information was sought in updated texts, web pages, magazines, scientific articles, virtual libraries and all valuable bibliographic material to facilitate the development of this study. Consequently, it was established that the effects caused by phytopathogenic diseases induce a decrease in profitability, due to poor management of the crop, susceptibility to pests, the use of non-certified seeds and unfavorable climatic conditions, which generated higher production costs based on of the use and application of pesticides to counteract the pathologies that cause the effects on the quality and productivity of the crop produced mainly by causal agents of phytopathogenic diseases. | es_ES |

| dc.description.abstract | En el Ecuador principalmente en la zona litoral el maíz duro amarillo (Zea mays L) es uno de los productos más importantes puesto que su abastecimiento enmarca diferentes actividades del sector agropecuario, siendo este uno de los cultivos transitorios mayormente sembrados por pequeños, medianos y grandes productores agrícolas. Sin embargo, entre los parámetros que afectan la producción del cultivo se encuentran las principales enfermedades Tizón foliar (Exserohilum turcicum), Mancha del asfalto (Phyllachora maydis), Roya común (Puccinia maydis), Pudrición de la mazorca (Diploidia zeae), Pudrición del tallo (Fusarium graminearum) y cinta roja (Spiroplasma kunkelli), cuya actividad inhibidora ha ocasionado grandes pérdidas en económicas, ya que el daño que ocasionan estas enfermedades como su sintomatología y afectación se presenta con mayor incidencia en la etapa reproductiva. En la investigación se empleó el método con enfoque cualitativo y alcance descriptivo. Además, para la elaboración de este documento se buscó información en textos actualizados, páginas web, revistas, artículos científicos, bibliotecas virtuales y todo material bibliográfico de valor para facilitar el desarrollo de este estudio. Por consiguiente se estableció, que Las afectaciones ocasionadas por enfermedades fitopatógenas inducen el decrecimiento de rentabilidad, debido al mal manejo del cultivo, la susceptibilidad de plagas, el uso de semillas no certificadas y condiciones climáticos desfavorables, lo cual generado mayor costo de producción en función del uso y aplicación de plaguicidas para contrarrestar las patologías causales de las afectaciones en la calidad y productividad del cultivo producidas principalmente por agentes causales de enfermedades fitopatógenas. | es_ES |
