Abstract Endophytic fungi constitute a great resource for the implementation of sustainable agricultural practices. However, their diversity may be altered by agrochemicals used in conventionally managed agrosystems. Here we explored culturable endophytic associated with avocado ( Persea americana Mill.) conventional and organic orchards from three counties world’s leading productive region. In total, 529 fungal isolates were obtained branches roots trees. Identification based on ITS sequencing showed that most belonged to Ascomycota phylum (98 %) grouped into 52 genera, representing 102 tentative species. The community was dominated genera which common both management types, namely Fusarium, Colletotrichum, Dactylonectria , Diaporthe / Phomopsis . Twenty exclusive (e.g., Hypoxylon Talaromyces ) 10 only found Trichoderma ). Fungal species richness higher than orchards. Ordination clustering analyses revealed stronger effect site type structure, highlighting influence local factors shaping community. Overall, our findings confirm negative impact crop-associated significant assemblages. Moreover, results emphasize need assess risk possible latent pathogens represent crop or dominant forest surrounding
