Animal and Plant Health Inspection Service

Subject: APHIS Removes Pale Cyst Nematode (Globodera pallida) Associated Fields from Regulation in Idaho

To: State and Territory Agricultural Regulatory Officials

On July 13, 2021, the Animal and Plant Health Inspection Service (APHIS) released two pale cyst nematode (PCN) associated fields, which have a combined area of approximately 271 acres, from regulation in Bingham County, Idaho. APHIS released the fields because the fields have completed a release protocol comprised of a sequence of surveys with negative laboratory results for PCN, in accordance with 7 CFR §301.86, subpart 3(d)(2).

With these changes, the current regulated area is 7,083 acres, of which 3,446 acres are infested fields, and 3,637 are associated fields. The infested fields are in an 8.5-mile radius that spans a portion of northern Bingham County and southern Bonneville County.

APHIS will follow up with a notice of this change to the regulated area in the Federal Register.

The specific PCN-regulated areas are on the following website:


For additional information about the PCN program, please contact the National Policy Manager, Lynn Evans-Goldner, at 301-851-2286.
