A standard method that gave good results was to flood the fields at a given time of the year. No details given since water is the main vector of nematodes. Perhaps they flood many fields at once.

Extensive research with Tagetes in England showed results to be erratic. Only certain strains have nematicide potentail and control involves ploughing the entire plants into the field and leaving them too fallow for many months. The supposedly nematicide power is actually biocide and has an inhibiting action against plant growth as well.
