dc.description | Corn is an agricultural product that is produced mostly in the world. According to its nutritional qualities to produce animal protein, human consumption, and industrial use, it has become one of the most important products in international markets. In Ecuador many families are dedicated to this activity, being Los Ríos where 45% of the country's production is concentrated. Science has long wondered how to activate a plant's defense system where and when it is needed, a field in which a breakthrough has just taken place. Because plants have a deficient immune system, it is necessary to generate mechanisms that increase these systems, it is necessary to use tools to produce plants, however, the appearance of new concepts of plant fungal control has allowed the flourishing of a new line of physiological activators. The objective of the research is to evaluate inducers of acquired resistance (IRA) on the asphalt stain complex in corn cultivation. The investigation was carried out on the grounds of the Hacienda "La Suerte", province of Los Ríos. In this study, the maize hybrid of the simple type Emblema was used. In the field work, an experimental design of "randomized complete blocks (BCA)" was used. The treatments were: salicylic acid, chitin, Peptide-Gramicidin, Poly-Glucosarine, Fosetyl Aluminum and a Control, all of them in two doses and applications, at 20 and 35 days after sowing. It was assessed: Incidence and severity of the disease with formulas, and severity of the disease with a diagrammatic scale. In addition, agronomic variables related to crop production were evaluated. The presence of grain spotting disease (Phyllachora maydis, Monographella maydi, Coniothyrium phyllachorae) was evident in the evaluation area. The application of physiological resistance activators generated control over the appearance of asphalt staining, compared to the control which was severely attacked. The application of salicylic acid 1.0 l/ha registered the least damage of the disease in all the evaluations. The highest production was achieved by applying salicylic acid asphalt stain control at 1,0 l/ha with 10166,67 kg/ha, the control had the worst average yield (4846,67 kg/ha). | es_ES |

dc.description.abstract | El maíz es un producto agrícola que se produce mayormente en el mundo. De acuerdo con sus cualidades alimenticias para la producción de proteína animal, el consumo humano y el uso industrial se ha convertido en uno de los productos más importantes en los mercados internacionales. En el Ecuador muchas familias se dedican a esta actividad, siendo Los Ríos donde se concentra el 45% de la producción país. Durante mucho tiempo la ciencia se ha estado preguntado cómo activar un sistema de defensa de una planta donde y cuando se necesita, un campo en el que se acaba de producir un importante avance. Los vegetales por poseer un sistema inmunitario deficiente es necesario generar mecanismos que aumenten estos sistemas, es necesario utilizar herramientas para producir plantas, sin embargo, la aparición de nuevos conceptos de control fúngico vegetal ha permitido el florecimiento de una nueva línea de activadores fisiológicos. El objetivo de la investigación evaluar inductores de resistencia adquirida (IRA) sobre el complejo mancha de asfalto en el cultivo de maíz. La investigación se ejecutó en los terrenos de la Hacienda “La Suerte”, provincia de Los Ríos. En este estudio se empleó el hibrido de maíz de tipo simple Emblema. En el trabajo de campo se utilizó diseño experimental de “bloques completos al azar (BCA)”. Los tratamientos fueros: acido salicílico, quitina, Peptídicos-Gramicidina, Poli-Glucosarina, Fosetyl Aluminio y un Control, todos ellos en dos dosis y aplicaciones, a los 20 y 35 dias después de la siembra. Se valoró: Incidencia y severidad de la enfermedad con fórmulas, y severidad de la con escala diagramática. Además, se evaluó variables agronómicas relacionadas con la producción del cultivo. Fue evidente la presencia de la enfermedad de manchado de grano (Phyllachora maydis, Monographella maydi, Coniothyrium phyllachorae) en la zona de evaluación. La aplicación de activadores fisiológicos de resistencia generó control sobre la aparición del manchado de asfalto, en comparación con el testigo el cual fue atacado severamente. La aplicación de ácido salicílico 1,0 l/ha registró el menor daño de la enfermedad en todas las evaluaciones. La producción más alta se logró aplicando para el control de mancha de asfalto acido salicílico 1,0 l/ha con 10166,67 kg/ha, el testigo tuvo el peor promedio de rendimiento (4846,67 kg/ha). | es_ES |
