Prevention of Spread
Plant-parasitic nematodes move only relatively short distances under their own power; therefore, the most usual means of nematode spread is the transportation of infested soil and infected plant parts by humans. Sanitation and good cultural practices are the best preventive measures against nematodes. Obtain plants from reputable nurseries and wash soil from tools and machinery before using them at a new location. Nematodes also might be carried by wind, water, and animals. These methods of spread can be important under certain situations such as when water runs from an infested site.
Establishment in a new area occurs only when sufficient numbers of viable nematodes are transported to a location where susceptible hosts are subsequently planted and where the environment is suitable for reproduction of the nematode species.
