An increasing number of researchers worldwide are showing interest in organic amendment of soil as means of nematode control. Numerous plant species with nematicidal compounds have been identified. Neem (Azadirachta indica) is considered the best-known example of plants with nematicidal properties and is available commercially in some parts of the world. Its efficiency has been proven locally, with the seed powder giving good control in both fields and greenhouses. Several materials are in use as organic amendments. However, the choice of materials for amendments will determine their efficiency in control. The use of disease-free organic amendments with a narrow C:N ratio will not only improve soil fertility but also reduce the level of nematodes and minimise the risk of increasing the level of another soilborne pathogens and pests.
