dc.descriptionThe present investigation developed the theme related to the chemical control of Asian soybean rust (Glycine max (L) Merril.). Worldwide, soybean cultivation is one of the most important oilseeds, therefore it is necessary to join efforts to improve its production, which is influenced by the quality of the grain at harvest; However, the factors that limit crop productivity are linked to soil management, unfavorable environmental conditions, incidence of pests, diseases and weeds. According to the information obtained, it was determined that the losses in soybean crops, due to the resistance of the Asian rust disease, oscillate between 25 and 80%, with chemical control being a main strategy to reduce the risk of the disease; the sowing of resistant varieties is a measure to reduce the attack of the disease at a lower cost, because the application of fungicides increases production costs / ha, therefore it causes low economic income; On the Ecuadorian coast, the months of October and November are considered the most critical periods for the incidence of the disease, due to the optimal temperature and relative humidity conditions; It is necessary to establish the crop between the months of May and June to avoid the proliferation of the disease and the plots treated with Difconazole + Strobirulins, alone or in mixtures, have a lower rate of rust severity in soybean plantations.es_ES

dc.description.abstractLa presente investigación desarrolló la temática referida al control químico de la roya asiática de la soya (Glycine max (L) Merril.). A nivel mundial, el cultivo de soya es una de las oleaginosas de mayor importancia, por tanto es necesario aunar esfuerzos para mejorar su producción, lo que se ve influenciado por la calidad del grano en la cosecha; sin embargo, los factores que limitan la productividad en el cultivo están ligado con el manejo de suelos, condiciones ambientales desfavorables, incidencia de plagas, enfermedades y malezas. De acuerdo a la información obtenida se determinó que las pérdidas en los cultivos de soya, debido a la resistencia de la enfermedad de Roya asiática oscilan entre el 25 y 80 %, siendo el control químico una estrategia principal para reducir el riesgo de la enfermedad; la siembra de variedades resistentes es una medida para disminuir el ataque de la enfermedad en menor costo, debido a que la aplicación de los fungicidas incrementa los costos de producción/ha, por tanto causa bajos ingresos económicos; en la costa Ecuatoriana, los meses de octubre y noviembre son considerados los periodos más críticos para la incidencia de la enfermedad, debido a que se presentan condiciones de temperatura y humedad relativa óptimas; siendo necesario establecer el cultivo entre los meses de mayo y junio para evitar la proliferación de la enfermedad y las parcelas tratadas con Difeconazole + Estrobirulinas, solos o en mezclas presentan menor índice de severidad de la roya en plantaciones de soya.es_ES
