Abstract

The exogenous application of hatching factors (HFs) to soil in the field gave an approximately 50% reduction in the population size of Globodera rostochiensis. This control was found to be due to a combination of suicide hatch and increased in-egg mortality caused presumably by incomplete hatch stimulation. The rates of hatch and emergence of J2s from cysts of G. rostochiensis were found to be dependent on hatching factor concentration in vitro and in the field. Encysted eggs of G. rostochiensis in the field during the first year of rotation after the previous year's potato crop were found to be more sensitive to HF concentration than those in the second year of rotation.
