Description
Summary:The antagonism and diversity of fungi have been studied in several environments, including agricultural soils. Nevertheless, information regarding fungi that are able to control Fusarium sp., Rhizoctonia sp. and Sclerotium rolfsii in integrated Crop-Livestock-Forest systems soils is unknown. Ten treatments were assessed, including monoculture, integration of Crop-Livestok-Forest, fallow and native forest. During the rainy and dry season was carried out fungi colony forming units (CFU), antagonistic potential and molecular identification. The results showed that CFU were higher in the rainy season and integrated systems of production. Fungal isolates as Penicillium, Talaromyces, Eupenicillium, Trichoderma, Aspergillus, Chaetomium, Acremonium, Curvularia, Purpureocillium, Bionectria, Paecilomyces, Plectospharella, Clonostachy, Mucor, Fennellia and Metarhizium were able to control Rhizoctonia sp., Fusarium sp. and Sclerotium rolfsii. This is the first report to describe culturable fungi species from the Amazon biome that are able to control pathogens. Furthermore, we suggest that integrated production systems can be a strategy for increasing fungal biomass and the rainy and dry season can modulate the density of soil fungi also, mainly in a tropical region.
