Potato Cyst Nematode (PCN) Phytosanitary Sampling
KirK Engineering & Natural Resources, Inc. and Northern Rockies Engineering, Inc. provide phytosanitary sampling for potato cyst nematode (PCN) as a contractor to USDA Animal and Plant Health Inspection Service (APHIS) and several state seed departments. PCN is a microscopic roundworm which causes growth retardation or at very high densities major crop loss. APHIS and state seed departments provide soil screening to verify that U.S. potatoes are PCN-free prior to export and to aid in early detection of PCN. To assist these agencies, we use USDA approved sampling methods for seed potato and commercial production fields, to ensure that fields remain free of this pest.
