PCN Regulated Field Description: August 1, 2025

Since the last update to the PCN regulated area on June 13, 2025, APHIS amended the pale cyst nematode (PCN) regulated area in Bingham County, Idaho as follows:

• Approximately 50.10 acres from a 56.28-acre PCN-associated field (Bingham County, Idaho – T01N, R37E, section 22) have been released from regulation. APHIS removed these acres because this land no longer meets the definition of an ‘associated field’ in accordance with 7 Code of Federal Regulations (CFR) §301.86-3(c)(2). In addition, this parcel was converted to non-agricultural use and is deregulated in accordance with 7 CFR §301.86- 3(d)(4).

With this change, the total number of PCN-regulated fields is 56, of which 31 are infested fields and 25 are associated fields. The current PCN-regulated area in Idaho is 6265.64 acres, of which 3,420.10 acres are infested fields and 2,845.53 acres are associated fields.  The infested fields are within an 8.5-mile radius that spans a portion of northern Bingham County and southern Bonneville County.
