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: Allen et al. ( 1955) reported the chemical to be an effective nematocide. Non-Fumigant Chemicals: The search for new systemic insecticides led to the development of a series of organophosphate and organocarbamate chemicals which are potential chemotherapeutants for nematode control. These are generally not phytotoxic at concentrations used for field control. 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.
