Because root knot nematodes don't move far in the soil without human help, neighboring plants may be infected while those at the end of the row remain healthy. To battle harmful nematodes, purchase plants and seed that are labeled nematode-resistant, and consider solarizing your soil during the summer prior to planting. The experiment was carried out in a sandy soil greenhouse in the Littoral NW Portugal.

Samples will be analyzed to determine the types and quantities of nematodes present in the soil, so appropriate recommendations for control can be made. Crop rotation: Although root knot nematodes have so many different plants they can infest, many gardeners recommend rotating susceptible crops in an alternating schedule with resistant or less susceptible species. The nematode resistant plants are characterized by failure of the nematodes to produce functional feeding sites in the host after invasion and to develop subsequently as reproducing females, including hypersensitive responses (Williamson and Kumar, 2006). Nematode-resistant plants will tolerate nematodes longer than other varieties, but plants bred to be nematode resistant can still be hosts to nematodes and can still increase the number of nematodes present in the soil, although less so than more susceptible varieties..
