PCN Regulated Field Description: June 13, 2025

• Removed one PCN-infested field in Bingham County (119.71 acres) because it completed a release protocol for PCN-infested fields. The protocol comprised a sequence of surveys with negative laboratory results for PCN in accordance with 7 Code of Federal Regulations (CFR) §301.86-3(d)(1) and criteria listed in the “Canada and United States Guidelines on Surveillance and Phytosanitary Actions for the Potato Cyst Nematodes, Globodera rostochiensis and Globodera pallida.”
• Changed the regulated acreage of a PCN-associated field in Bonneville County by adding 2 acres to the south side of this field because it is now being farmed as one unit. We made this change in accordance with 7 CFR §301.86-3(a). In addition, we deregulated 19.07 acres from the west side of the same field because this land no longer meets the definition of an "associated field" in accordance with 7 CFR §301.86-3(c)(2); this 19.07-acre parcel of land is now a residential property.

With these changes, 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 6,315.74 acres, of which 3,420.10 acres are infested fields and 2,895.63 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.
