Isolation and identification of nematophagous fungi from native rice-producing areas of Costa Rica. The objective of this study was to isolate and identify nematophagous fungi from rice-producing areas of Costa Rica. The study was conducted between April 2008 to August 2009. Soil from three rice-producing regions of Costa Rica, Central Pacifi c, Atlantic and Region Huetar Chorotega were analyzed by the sprinkling plate method in search of nematophagous fungi. The fungal isolated were identifi ed as Trichoderma sp., Paecilomyces sp., Fusarium oxysporum, Fusarium tabacinum, Fusarium sp., Monacrosporium sp., Aspergillus sp., Geotrichum sp., Phythium sp., Cladosporium, Curvularia sp., Phoma sp., Oomycete and sterile mycelium. The results suggest a high diversity of nematophagous fungi with potential for use as biological control agents.
