Relationship between soybean delayed harvest and the presence of pathogens on seeds and stubble

Soybean delayed harvest may affect the sanitary seed quality, and thus itsuse for the following sowing season. The seed pathogens negatively affect the seed vigor and the normal seedling development hence affecting  optimum crop implantation. The goal of this study was to assess the effect of the so...

The seed pathogens negatively affect the seed vigor and the normal seedling development hence affecting  optimum crop implantation. The goal of this study was to assess the effect of the soybean delayed harvest due to adverse climatic conditions on the incidence of seed. The assessments were carried out during two seasons (years 2016 and 2018) in Pergamino, province of Buenos Aires, Argentina. The seeds and stems sanitary analyses were carried out using a blotter test and moist chamber respectively. The fungal reproductive structures were observed through morphological studies under  stereoscopic and optical microscope. The results of this study showed that soybean delayed harvest due to adverse climatic factors significantly increased the incidence of seed pathogens (p < 0.0001) and the presence of fungal reproductive structures on the stems (p < 0.0001). La cosecha demorada de soja puede afectar la calidad sanitaria de la semilla y la posibilidad de su uso para la siembra. Los patógenos de semillas afectan negativamente el vigor y el desarrollo normal de las plántulas y, por lo tanto, la buena implantación del cultivo. El objetivo de este trabajo fue evaluar el efecto de la demora en la cosecha por condiciones climáticas adversas, sobre la incidencia de los patógenos en las semillas, y la presencia de estructuras fúngicas reproductivas en los tallos. Las evaluaciones se realizaron durante   dos años (2016 y 2018) en la localidad de Pergamino, provincia de Buenos Aires, Argentina. Los análisis sanitarios de semillas y tallos se efectuaron a través del blotter test y cámara húmeda respectivamente; con posterior observación de estructuras reproductivas mediante estudios morfológicos bajo microscopio estereoscópico y óptico. Los resultados de esta experiencia  demostraron que la cosecha demorada de soja por factores climáticos adversos incrementó significativamente la incidencia de patógenos en las semillas (p < 0,0001) y la presencia de estructuras fúngicas de resistencia en los tallos (p < 0,0001).
