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.
