In this paper, four nematophagous fungi (NVC 7.4, 28.8 NVC, NVH 14.9, 12.5 NVH) isolated from soils grown coffee and pepper in Dak Lak and Gia Lai provinces of Vietnam were studied to clarify their ability in nematode trapping under laboratory, green house and field conditions. The result showed that they had multi-trap ability for different species of nematodes, especially Meloidogyne arenaria and Meloidogyne incognita caused harm on pepper and Pratylenchus coffea caused harm on coffee in Vietnam. Four nematophagous fungi had plant parasitic nematode trapping effect reaching 51.36 - 72.37% in laboratory, 46.46 to 74.29% in greenhouse and 49.45 to 67.31% in field conditions These nematophagous fungi are promising resource that can be applied to control plant parasitic nematodes on coffee and pepper farming in Vietnam.
