Pale Cyst Nematode (Globodera pallida) – Addition of regulated areas in Idaho

Country: United States

Title: Pale Cyst Nematode (Globodera pallida) – Addition of regulated areas in Idaho

Jonathan Jones, National Policy Manager for Potato Cyst Nematode Programs, at 301-851-2128.


Effective December 29, 2014, the Animal and Plant Health Inspection Service (APHIS) added 994 acres to the pale cyst nematode (PCN) regulated area in Bingham County, Idaho. APHIS took this action based on the confirmations of PCN cysts in soil samples from four potato production fields in Bingham County between October 28 and December 8, 2014. This action brings the number of PCN-infested fields to 26 and the infested area to 2,897 acres. The total area in Idaho under regulation is 7,734 acres.

In accordance with the PCN regulations, APHIS has applied safeguarding measures on the interstate movement of PCN-regulated articles from these areas. APHIS will follow up with a notice of this change to the regulated area in the Federal Register. The specific PCN-regulated areas can be found at:

The cysts were found in soil samples during routine delimiting surveys and ongoing cooperative monitoring efforts by APHIS and the Idaho State Department of Agriculture. All infested fields are within a 7.5-mile radius that spans a portion of northern Bingham County and southern Bonneville County. After APHIS completes the trace investigation for this most recent find, any additional acres that need to be regulated due to their primary association with the newly infested acres will be listed on the PCN program website provided above.

Under IPPC Standards, Globodera pallida is considered a pest that is present: only in some areas and subject to official control in the United States.
