or the past decade, pale cyst
nematode (PCN) has been an
unwelcome topic for potato
growers.
While the destructive parasites aren't
eradicated in eastern Idaho, where
most of the potato field contamination
has occurred, efforts are making

progress. In 2007, nearly 20,000 acres
were part of the U.S. Department of
Agriculture Animal and Plant Health
Inspection Service's (USDA-APHIS)
regulated area. As of Dec. 1, 2018, that
number was down to 7,554, with 3,277
acres still classified as infested.
To be infested, inspectors must
find at least two cysts from two
different soil samples with one of
those cysts containing viable PCN
Pale cyst nematode infestation still present in
Idaho, but affected acreage shrinking
eggs or juveniles. Regulated fields are
fields that have been exposed to soil or
other articles containing PCN and are
considered high risk for infestation.
The infestation has been contained
to an area with an 8.5-mile radius
that spans portions of Bingham and
Bonneville counties, mostly located
southwest of Idaho Falls.
If unchecked, PCN can cause up to
80 percent yield loss in potato fields,
