Globodera pallida or the pale potato cyst nematode (PCN) can have a major impact on both the production and marketing of potatoes from Idaho and the United States. Control of the recent infestation in Southeastern Idaho will require both short term and long term approaches. The short term approaches are designed to reduce the presence of PCN in the soil to the level where it no longer a threat to potato production or export. This will be done by identifying soil fumigants, soil biofumigants, and bacterial and fungal biocontrol agents that effectively reduce the viability of PCN cysts currently in the soil. Long term approaches will be developed to minimize the potential for reinvestation of U.S. potato production fields in the future. This will be done by facilitating the identification and development of G. pallida resistant potato cultivars.
Using the combination of short term and long term approaches to control G. pallida will make it possible to eliminate the current threat to U.S. potato production and defend against G. pallida becoming a threat to the U.S. potato industry in the future.
