Field tests were conducted to clarify the seeding time and seeding rate for the highest antagonistic effect on nematode density by Lycopersicon peruvianum, Solanum sisymbriifolium and S. nigrum cultivation in Globodera rostochiensis (PCN) infested fields at Shiribeshi County, Hokkaido, Japan. Hatchability of PCN in soil sown with L. peruvianum was much greater than S. sisymbriifolium and S. nigrum, and decreasing densities of PCN in L. peruvianum soil was the highest among the three solanaceous plants. The antagonistic effect of spring sowing (June) of L. peruvianum was greater than summer sowing (August), and an excellent effect was obtained at the 1 kg/10 a seeding rate for spring sowing of L. peruvianum, which was equivalent to the effect of the resistant potato variety 'Hana-Shibetsu' (H1).
