This study aimed to determine the main pathogens present in Senegalia polliphyla (DC.) seeds and to evaluate the fungicidal potential of Metrodorea flavida (K. Krause) extracts. For this purpose, concentrations of 0.5, 1.0, 1.5 and 2.0% of the extract of Metrodorea flavida leaves were used, in an ethanolic or aqueous form. The experiment was carried out using the Blottertest method to assess the incidence of pathogens in seeds and after application of treatments. Thus, the effect of extracts on the incidence of pathogens and the effects of the extracts on the germination and morphological characteristics of the seedlings was analyzed. The main pathogens found in Senegalia polliphyla seeds were Aspergillus flavus and Fusarium oxysporum. The aqueous and ethanolic extracts reduced the infestation of pathogens associated with Senegalia polliphyla seeds, as well as the main fungus found: Aspergillus flavus Link. It was also found that the extracts did not influence the germination and morphological characteristics of Senegalia polliphyla seedlings in all concentrations evaluated, thus being a promising alternative for pathogen control in forest seeds.
