Nematicide

Nematicide

A nematicide is a type of chemical pesticide used to kill parasitic nematodes. One common nematicide is obtained from neem cake, the residue obtained after cold-pressing the fruit and kernels of the neem tree. Known by several names in the world, the tree was first cultivated in India in ancient times and is now widely distributed throughout the world. The root exudate of marigold (Tagetes) is also found to have nematicidal action. Nematophagous fungi, a type of carnivorous fungi, can be useful in controlling nematodes, Paecilomyces being one example.

Prior to 1985, the persistent halocarbon DBCP was a widely used nematicide and soil fumigant. However, it was banned from use after being linked to sterility among male workers; the Dow Chemical company was subsequently found liable for more than $600 million in damages.

Besides chemicals, soil steaming can be used in order to kill nematodes. Superheated steam is induced into the soil which causes almost all organic material to deteriorate.
