An agroforestry system (SAF) is characterized by having a diversity of components, such as timber and non-timber forest species and crops, pastures, or a livestock production system. This diversity of components in the system reduces the intensity of diseases, e.g. foliar diseases. This study aimed to detect the fungal microorganisms associated with the leaf spots of plant species that are part of the agroforestry production systems of the Peruvian farmers from Yurimaguas and to determine the level of incidence of the leaf spots in the systems of agroforestry production. Different land cropping systems were implemented in the farms, such as palm (Bactris gasipaes) to produce palm hearts, cocoa (Theobroma cacao), and plantain (Mussa sp.). Also, silvopastoral systems with fast and slow growing timber species and cattle with pastures for grazing and reforestation in areas of secondary fores...
