Area-wide Nematodes

Field locations for seed and tablestock potatoes for growers who export were sampled in September, October and November. A total of 48 soil samples were taken in 10 counties across Nebraska. Samples will be analyzed by the UNL Plant Pathology Department for the presence of quarantine and export significant nematodes including: potato rot (Ditylenchus destructor); potato cyst (Globodera pallida, G. rostochiensis); soybean cyst nematode (Heterodera glycines); root knot nematodes (Meloidogyne chitwoodi, M. hapla, M. javanica); and other plant parasitic nematode genera. Dr. Tom Powers, UNL nematologist, and his staff will conduct morphological and molecular diagnostics of all adult and juvenile nematodes found in the soil samples. The identification of plant parasitic nematodes will establish and maintain pest-free areas for the export of plants and plant products. The documentation of species distribution will document compliance to certification of potatoes. All samples have been sent to the University of Nebraska for analysis.
