APHIS Adds Pale Cyst Nematode (Globodera pallida) Associated Fields and Removes Other Fields from Regulation in Idaho

TO:  State and Territory Agricultural Regulatory Officials 

On January 28, 2021, the Animal and Plant Health Inspection Service (APHIS) added 444 acres to the pale cyst nematode (PCN)-regulated area in Bingham County, Idaho, and released from regulation approximately 240 acres of associated fields in Bonneville County, Idaho. APHIS added the Bingham County fields because of the association of these fields with a PCN-infested field that was previously reported (DA-2020-01). APHIS has applied safeguarding measures on the interstate movement of PCN-regulated articles from these fields. APHIS released approximately 240 acres of associated fields in Bonneville County, Idaho, 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 7,354 acres, of which 3,446 acres are infested 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:
