UW Extension’s Plant Diagnostic Clinic Offers Free Identification Services

University of Wyoming Extension has reopened its Plant Diagnostic Clinic, which assesses
plant samples that may harbor diseases.
Based in Laramie but serving communities statewide, the Plant Diagnostic Clinic supports
county extension educators and community members by diagnosing possible diseases in
any type of plant, including houseplants, turf, row crops, forages and even trees.
The clinic also provides disease management suggestions. Recommendations could include
chemical controls, alternative irrigation practices or resistant plant varieties to
grow instead.
Plant diagnostic services are free and open to any member of the public, from home
gardeners to commercial producers. However, those interested in submitting samples
are encouraged to reach out to their local extension offices before contacting the
diagnostic clinic directly.
“The first point of contact should be someone in your county,” says Jean Williams-Woodward,
UW Extension plant pathologist and director of the Plant Diagnostic Clinic. “A lot
of times, county educators know what’s specifically happening in their county.”
For example, if a county is experiencing a wave of a particular plant problem, a local
extension educator could likely provide a diagnosis more quickly than the diagnostics
team in Laramie. If county educators cannot provide answers, they can facilitate contacting
the clinic for assistance.
After submitting samples, submitters and county educators will receive official reports
with plant diagnoses and recommendations.
