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 field and screenhouse. Several materials are in use as organic amendment. However, the choice of materials for amendment will determine its efficiency in control. The use of organic amendments that are disease-free and with a narrow C:N ratio will improve soil fertility while more efficiently reducing the level of nematodes and minimising the risk of increasing the level of another soil borne pathogens and pest
