The use of certified disease free seed will also assure that potato cyst nematodes are not present due to planting infected tubers. Soil testing for potato cyst nematodes is also crucial in keeping track of the prevalence of the nematodes. Controlling the quantity of the nematodes allows the prevention of an epidemic.

About one hundred eggs are laid in batches, 2 to 5 cm (0.8 to 2.0 in) beneath the soil and hatch after about two weeks. The larvae develop in the soil for two to four years. They feed on seeds and seedlings and the new tillers of cereal crops, and gnaw their way into roots, finding their food by smell.
