A five-year nematological survey on the incidence of potato cyst nematode (PCN) in the potato production areas of Atok, Modaymen, Natubleng, Sinipsip, Pactil, Cada, located in Benguet and Mountain Province [Philippines] was conducted in 748 farms. Only 49 fields had infestations with counts of cyst per 100 grams soil ranging from 1 to 312, an average of 300 eggs/larva per cyst. Results also indicated that harvesting of potato tubers 70 to 80 days after planting reduced PCN population densities. In addition, the reproduction rate of the nematode decreased to about 30% after a four-year crop season by planting susceptible and resistant potato varieties alternated with non-host crops such as cabbage, sweet peas, and carrots.
