Abstract
El presente trabajo de investigación titulado “Efecto de tres dosis de chlorothalonil + dimethomorph en el control de Peronospora variabilis Gäum. en Chenopodium quinoa Willd. Var. Salcedo INIA en Laredo - La Libertad”, se realizó en el fundo Santa Rosa, en el sector de San Carlos perteneciente al distrito de Laredo, Departamento de La Libertad desde el 14 de Julio del 2014 al 11 de Octubre del 2014. Los objetivos fueron: Evaluar el efecto de tres dosis de chlorothalonil + dimethomorph en el control del mildiu Peronospora variabilis Gäum. en Chenopodium quinoa Willd. Var. Salcedo INIA en Laredo - La Libertad. Determinar cuál de las tres dosis de clorothalonil + dimethomorph producirá el mejor control del mildiu Peronospora variabilis Gäum. en Chenopodium quinoa Willd. Var. Salcedo INIA en Laredo - La Libertad. Se utilizó el diseño de bloques completos al azar (DBCA) con tres repeticiones y tres tratamientos del fungicida a base de chlorothalonil + dimethomorph, donde el T1 estuvo constituido por una dosis de 0.5 K/cil, el T2 por 1 K/cil. y el T3 por 1.5 K/cil. En cuanto al efecto de las tres dosis de clorothalonil + dimethomorph en el control de Peronospora variabilis Gäum se encontraron estadísticamente diferencias significativas y altamente significativas en las características evaluadas tanto en el porcentaje de incidencia y el porcentaje de severidad de área foliar afectada, siendo el T3 (1.5 K/cil.) el que presento mejores resultados.
ABSTRACT This research paper entitled “Effect of three doses of chlorothalonil + dimethomorph in the control of Peronospora variabilis Gäum. in Chenopodium quinoa Willd. Var. Salcedo INIA in Laredo – La Libertad”, was held at the Santa Rosa estate in the area of San Carlos belonging to the district of Laredo Department of Freedom July 14, 2014 until October 11, 2014. Objectives were: Evaluate the effect of three doses of chlorothalonil + dimethomorph in controlling mildew Peronospora variabilis Gäum. in Chenopodium quinoa Willd. Var. Salcedo INIA in Laredo - La Libertad. Determine which of the three doses of Clorothalonil + dimethomorph produce the best control mildew Peronospora variabilis Gäum. in Chenopodium quinoa Willd. Var. Salcedo INIA in Laredo - La Libertad. The design of complete random (DBCA) blocks with three replications and three treatments based fungicide chlorothalonil + dimethomorph, where T1 was made of a dose of 0.5 K / cil, the T2 by 1 K / cil. was used and T3 by 1.5 K / cil. As for the effect of three doses of Clorothalonil + dimethomorph in the control of Peronospora variabilis Gäum statistically significant and highly significant differences in the characteristics evaluated both in the percentage of incidence and severity of the percentage of affected leaf area they are found to be statistically T3 (1.5 K / cyl.) that presented the best results.
