A pesar de su importancia, información sobre el agente causal y epidemiología no se encuentran bien documentados en Colombia, limitando el establecimiento de herramientas de manejo. El objetivo fue determinar las dinámicas espacio-temporales y el impacto de la MT de la papa asociada a Verticillium a escala micro (lote) y meso (regional) en Cundinamarca, Colombia. Para ello, se colectó material vegetal para el aislamiento y se recopiló información edafoclimática y del sistema productivo a nivel regional. A escala micro se hizo seguimiento de la incidencia y severidad de la MT y al final del ciclo se cosecharon los tubérculos y se evaluaron los parámetros de rendimiento y calidad. A nivel temporal se realizó el análisis del desarrollo de la curva de progreso de la enfermedad evaluando modelos temporales y a nivel espacial se implementaron análisis de patrones puntuales y geoestadística. Como resultado, se identificaron cinco morfotipos de Verticillium spp. como agente causal. La MT estuvo presente en todas en las provincias evaluadas con prevalencia del 28.6% para Cundinamarca y se encontró asociada a factores epidemiológicos como movimiento de suelo por maquinaria y ciclos continuos de siembra. Los análisis espacio-temporales indicaron que la MT presentó patrones espaciales agregados o aleatorios y el modelo logístico fue el que mejor representó la curva de progreso. La enfermedad redujo la producción por planta entre el 24 y 46% en peso, afectando la cantidad de tubérculos en las categorías gruesas. Nuestro trabajo indica que el patógeno se encuentra establecido en el suelo, bajo las condiciones del sistema productivo en Cundinamarca y que podría ser un limitante para la producción del cultivo de papa. (Texto tomado de la fuente).Potato early dying (PED) caused by species of the genus Verticillium is a limiting disease that results in losses between 10 and 50% globally. Despite its significance, information of the causal agent, epidemiology, and disease status in Colombia is not well documented, hampering management tools. The main objective of this research was to determine the spatial-temporal dynamics and the impact of EM associated with Verticillium at micro and meso-scales in the department of Cundinamarca, Colombia. To achieve this, plant material was collected for the isolation and characterization of the causal agent. Edaphoclimatic information and regional production system data were compiled. The incidence and severity of EM were monitored at the plot level, and at the end of the crop cycle, tubers were harvested to assess yield and quality parameters. Classic temporal models of the disease progress curve were evaluated, and at the spatial level, point pattern analysis and geostatistics were implemented. As a result, Verticillium spp. was identified as the causal agent, and five pathogen morphotypes were found. EM had a prevalence of 28.6% in Cundinamarca, with presence in all evaluated provinces, and it was associated with regional epidemiological parameters such as soil movement by machinery and continuous planting cycles. The spatial-temporal analyses indicated that EM exhibited a spatial pattern of aggregation or randomness, and the disease progress curve was best represented by the logistic model. The production per-plant was reduced by 24 to 46% in weight due to the disease, affecting the quantity of tubers in the zero and first quality categories. Our work suggests that the pathogen is established within the conditions of the production system in Cundinamarca and could be a limiting factor for potato crop production.
