The application of fungicides is one of the main strategies for its management; however, the pathogen has developed resistance to groups of fungicides. In search of a new control alternative, the antagonistic activity of 40 strains of endophytic fungi (EF) on <em>B. cinerea </em>was evaluated at the National University of Cañete. Antibiosis tests were performed with the extraction of secondary metabolites from the strains of HE and mycoparasitism with the method pre-colonized plate by the pathogen, where the mycelial inhibition of the pathogen and HE colonization, respectively, were evaluated. The metabolites obtained from the genus <em>Aspergillus</em> (strain 111) completely inhibited the mycelial growth of pathogen, followed by the genera <em>Nigrospora</em> (58) and <em>Aspergillus</em> (117) with 89.82 % and 63.33 % respectively compared to <em>Cladosporium</em> (116) which had less effect towards the pathogen with 3.19 % mycelial inhibition. However, all the strains of the genus <em>Trichoderma</em> (1, 91, 93 and 94), <em>Alternaria</em> (5 and 78), <em>Fusarium</em> (106), <em>Cladosporium</em> (41) and <em>Lasiodiplodia</em> (49) completely colonized the pathogen and were considered as more aggressive mycoparasites followed of the 117 and 111 <em>Aspergillus</em> strains that colonized 83.33 % and 63.33 % to the pathogen respectively. These endophytic fungi with antagonistic activity towards <em>B. cinerea </em>could be used as an alternative for disease control in blueberry cultivation.</p&gt;}, number={3}, journal={Bioagro}, author={Leon-Ttacca, Betsabe and Yactayo-Yataco, Richard and Astete-Farfán, Almendra and Mattos-Calderón, Luz and Arestegui-Cantoral, Jasmín}, year={2022}, month={Aug.}, pages={209-220} }
