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...

| Sumario: | 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 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). |
