Answer: Nematodes in the soil are best controlled using a combination of practices that will reduce the nematode population to numbers that will not cause significant plant damage. The following practices can be used to reduce nematode numbers:
Plant nematode resistant varieties.
Plant non-host plants in rotation with susceptible varieties.
Till the soil during the summer months to remove soil moisture (must be done after plants have been removed).
Cover the soil with clear plastic and leave in place for 6 to 8 weeks during June, July, August or September.
While you can't eliminate all nematodes the above practices can reduce the population of nematodes in the soil. You can almost never. Since you cannot completely eliminate nematodes, each year you will need to repeat these steps.
