Potato Cyst Nematode, ID (FY2009) Grant uri icon



  • The potato cyst nematode (Globodera pallida) is a new pest of potato production fields in southern Idaho and potential impact on potato-based agricultural economies is significant. This project will investigate biological and chemical approaches to controlling G. pallida and develop educational program for potato producers in southern Idaho on control and prevention of G. pallida. The first objective involves evaluating the use of biofumigants from the genus Brassica and Sinapis to reduce G. pallida cyst viability by using seed meal and liquid extracts. The second objective is to isolate and identify possible biocontrol organisms from G. pallida cysts. The third objective is to evaluate potato germplasm for resistance to G. pallida. The fourth objective is to evaluate potential trap crops for G. pallida. The fifth objective is to develop potato grower education programs to minimize threat of infestation by G. pallida. The sixth objective is to evaluate an extract from a pathogen of wheat as a potential control method for G. pallida. The seventh objective is to continue research on the life cycle of G. pallida to insure adequate production of G. pallida cysts in laboratory and greenhouse to supply the cysts needed for the other objectives of this project. By combining several approaches to control G. pallida, a management plan for G. pallida will be developed that would increase the potential for elimination of G. pallida from Idaho production fields and minimize the economic impact on potato production based agricultural economies of the western United States.
