How to Control Nematode: Chemical, Physical and Biological Control
These are discussed in brief here:
Chemical Control:
Fumigants:
Non-Fumigant Chemicals:
Cultural Practices:
They result in partial or complete control of nematodes and include:
Crop Rotation of Non-Host Plants:
Physical Methods:
Biological Control:

Content: A major drawback with them is that they are highly toxic to mammals. ADVERTISEMENTS: These chemicals are dispersed in the soil by water. Nematicidal action is limited to the narrow root zone. Nematicidal activity is usually due to narcotization and behaviour modification rather than the killing of the nematodes. Interference in the nematode infection, development and reproduction can temporarily slow or halt an increase in the number of nematodes. Chemical control of nematodes has not made much headway in India mainly due to the prohibitive cost of the nematicides, difficulty of application over large areas and the lack of awareness of the nematode problem. In spite of high initial costs of nematocides, there is increasing evidence that a judicious use of these chemicals would be economical on selected crops, such as cotton, sugarcane, citrus, grape vine, potato, vegetables and even wheat and barley in heavily infested fields. Cultural Practices: They result in partial or complete control of nematodes and include:
