| Sumario: | In order to determine the threat that plant-parasitic nematodes pose to crop production, it is essential to establish an accurate estimation of their presence. The extraction efficiency from soil, therefore, is a critical step in establishing disease pressures presented by nematodes or the conditions of soil health. To achieve high nematode extraction efficiency, various methods and modifications have been developed over time (Oostenbrink, 1954; Seinhorst, 1956; Harrison & Green, 1976; Viaene et al., 2021) with variations being introduced locally, depending on the availability or access to certain materials.
