description Potato (Solanum tuberosum) is the fourth most important crop worldwide. The crop is affected by the climate variability, mainly in relation to diseases severity and pathogens survival, which is the case of late blight caused by Phytophthora infestans. The objective of this study was to evaluate the effect of the climatic elements on late blight severity. The study was carried out in the municipality of Mosquera, Cundinamarca, Colombia, from December 2015 to May 2016. The potato varieties Diacol Capiro (DC), ICA-Unica (IU) and Pastusa Suprema (PS) were included in this study. Data of late blight severity together with data of precipitation (Pr), relative humidity (RH), temperature (T), wind speed (VV), solar brightness (BS) were recorded, and with these data the agroclimatic indices water index (IH), temperature degree day (GD) and evapotranspiration reference (ETo) were calculated. There was a significant positive correlation (p < 0.05) of late blight severity in the three varieties with IH (0–158 ± 58), precipitation (0–63 mm ± 23 mm) and minimum temperature (2-10 °C ± 2 °C), and significant negative correlation (p < 0.05) of P. infestans severity with BS (2–7.7 h day-1 ± 1.7 h day-1). The GD (0–4 °Cd ± 1 °Cd) presented a significant positive correlation with DC and PS, and also positive correlation with the mean temperature (11–15.3 °C ± 1.41 °C) with DC. The ETo (0.4–3.3mm day-1 ± 0.87mm day-1) and maximum temperature (19.9–23 °C ± 0.75 °C) were significantly and negatively correlated with DC and PS, and also between VV (5 .27–7.95 km h-1 ± 0.79 km h-1) with DC. It was concluded that climatic variables influenced late blight severity and P. infestans survival.

El objetivo del trabajo fue evaluar el efecto de los elementos climáticos en la severidad del tizón tardío en el cultivo de papa. El estudio se realizó en el municipio de Mosquera, Cundinamarca, Colombia, entre diciembre del 2015 y mayo del 2016. Se evaluaron las variedades Diacol Capiro (DC), ICA-Única (IU) y Pastusa Suprema (PS), en las que se registró semanalmente la severidad del tizón tardío en conjunto con datos de precipitación (Pr), humedad relativa (HR), temperatura (T), velocidad del viento (VV), brillo solar (BS); datos con los que se calcularon los índices agroclimáticos: índice hídrico (IH), grados día (GD) y evapotranspiración de referencia (ETo). En este estudio se presentó correlación positiva significativa (p < 0,05) entre la severidad de tizón en las tres variedades, con el IH (0–158 ± 58), la precipitación (0–63 mm ± 23 mm) y la temperatura mínima (2-10 °C ± 2 °C), y correlación negativa significativa (p < 0,05) con el BS (2–7,7 h día-1 ±1,7 h día-1). Los GD (0–4 °Cd ± 1 °Cd) presentaron correlación positiva significativa con DC y PS, y también correlación positiva entre la temperatura media (11–15,3 °C ± 1,41 °C) con DC. La ETo (0,4–3,3 mm día-1 ± 0,87 mm día-1) y la temperatura máxima (19,9–23 °C ± 0,75 °C) se correlacionaron negativamente con DC y PS, y también entre la VV (5,27–7,95 km h-1 ± 0,79 km h-1) con DC. Se concluyó que las variables climáticas influyeron en la severidad y supervivencia de P. infestans en el cultivo de papa.Universidad Central del Ecuador2022-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlapplication/ziptext/xmlhttps://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/400810.29166/siembra.v9i2.4008Siembra; Vol. 9 No. 2 (2022): SIEMBRA; e4008Siembra; Vol. 9 Núm. 2 (2022): SIEMBRA; e40082477-88501390-892810.29166/siembra.v9i2reponame:Revista Siembrainstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4008/4977https://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4008/4979https://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4008/4980https://revistadigital.uce.edu.ec/index.php/SIEMBRA/article/view/4008/4981Derechos de autor 2022 Wilmar Alexander Wilches Ortiz, Ruy Edeymar Vargas Diaz, Eduardo María Espitia Malagónhttps://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccess2022-11-22T20:34:13Zoai:revistadigital.uce.edu.ec:article/4008Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/**Ecuador*2477-88501390-8928opendoar:*2022-11-22T20:34:13Revista Siembra - Universidad Central del Ecuadorfalse
