【 摘 要 】

Soybean delayed harvest may affect the sanitary seed quality, and thus itsusefor the following sowing season. The seed pathogens negatively affect the seedvigor and the normal seedling development hence affecting optimum cropimplantation. The goal of this study was to assess the effect of the soybeandelayed harvest due to adverse climatic conditions on the incidence of seed pathogens and the presence of fungal reproductive structures on the stems.The assessments were carried out during two seasons (years 2016 and 2018)in Pergamino, province of Buenos Aires, Argentina. The seeds and stemssanitary analyses were carried out using a blotter test and moist chamberrespectively. The fungal reproductive structures were observed throughmorphological studies under stereoscopic and optical microscope. The resultsof this study showed that soybean delayed harvest due to adverse climaticfactors significantly increased the incidence of seed pathogens (p<0.0001)and the presence of fungal reproductive structures on the stems (p<0.0001).
