Developmental models of peanut pox Arachis hypogaea L.
The incidence of leaf spot on peanut (Arachis hypogaea L. cv. Runner) caused by a complex of Cercospora arachidicola Hori and Cercosporidium personatum (Berk. & Curt.) Deighton, was evaluated during the 1986/87, 1987/88, and 1988/89 growing seasons. Three non-linear models were used for desc...

| description | The incidence of leaf spot on peanut (Arachis hypogaea L. cv. Runner) caused by a complex of Cercospora arachidicola Hori and Cercosporidium personatum (Berk. & Curt.) Deighton, was evaluated during the 1986/87, 1987/88, and 1988/89 growing seasons. Three non-linear models were used for describing disease progress in time. The models' evaluation criteria include significant estimated parameters, randomness of the residuals, the standard deviation about the regression line, and the coefficient of determination (R²). The fits were better for Exponential and Logistic models in 1986/87 and 1988/89, and for Logistic and Gompertz models in 1987/88. |

Durante las campañas agrícolas 1986/87, 1987/88 y 1988/89, se evaluó la incidencia de la viruela del maní Arachis hypogaea L. causada por Cercospora arachidicola Hori y Cercosporidium personatum (Berk. y Curt.) Deighton. Para describir las epifitias, se analizaron tres modelos no lineales: Exponencial, Logístico y Gompertz. Para evaluar el ajuste de los diferentes modelos, se consideró la significancia de los parámetros estimados, la dispersión de los residuos, la desviación estándar de la regresión lineal y el coeficiente de determinación (R²). En las campañas 1986/87 y 1988/89, el mejor ajuste se obtuvo con el modelo Exponencial, seguido por el Logístico; y en el ciclo 1987/88, esta relación ocurrió con los modelos Logístico y Gompertz.
