Como una de las posibles medidas de manejo deaplicación práctica para la reducción de inóculo de Spongospora subterranea f. sp. subterranea en suelos infestados con quistosoros del patógeno, se evaluó la incidencia de su infección en diferentes plantas hospederas durante tres siembras consecutivas. Las siembras se realizaron en macetas que contenían 2 kg de suelo previamente inoculados con una concentración de 1x105quistosoros.g-1 de suelo; las cosechas de las plantas se realizaron cada tres meses, seleccionando dos muestras de raíz por maceta, una para observación de estructuras del patógeno por microscopía de luz, previa tinción con azul de tripano al 0,05% y otra para detección molecular mediante PCR en tiempo real (qPCR). Para el análisis estadístico se evaluaron los modelos Exponencial y Monomolecular, con el objetivo de seleccionar el que mejor se ajustara a los datos obtenidos. Según el valor estimado para la incidencia de estructuras del patógeno en las raíces, en las especiesCyphomandra betacea, Physalis peruvianum, Solanumnigrum, Allium cepa, Solanum quitoense y Rumex crispus,se reduce la presencia de quistosoros y zoosporangios después de tres siembras consecutivas en condiciones de casa de malla, mientras que en las especies Petroselinum crispum, Pennisetum clandestinum, Zea mays y Solanum lycopersicum se aumenta la incidencia de estructuras de S. subterranea f. sp. subterranea en las raíces. / Abstract. Trap crops have been considered an alternative strategy to reduce the inoculum of soil pathogens such as Spongospora subterranea f.sp. subterranea. In this work, the incidence of this pathogen was evaluated at three consecutive sowings using different alternative hosts. Plants were sown in pots containing 2 kg of soil inoculated with 1x105 cystosori per gram and harvested every three months. Roots were tested for the presence of cystosori and zoosporangia using light microscopy observations with trypan blue (0.05%) and Real-time PCR (qPCR). Data fitting was performed using Exponential and monomolecular models. According to the estimated incidence values of pathogen structures, plant species Cyphomandra betacea, Physalis peruvianum, Solanum nigrum, Allium cepa, Solanum quitoense and Rumex crispus, significantly reduced the amount of cystosori and zoosporangia after the three consecutive sowings. In contrast, Petroselinum crispum, Pennisetum clandestinum, Zea mays and Solanum lycopersicum increased the incidence of S. subterranea f. sp. subterranea.
