Plant Diagnostic Lab/ Plant Health Program
What is the UNH Plant Diagnostic
Laboratory?
The UNH Plant Diagnostic Lab (UNH-PDL) is a diagnostic facility funded by UNH
Cooperative Extension. The diagnostic services offered by the UNH-PDL include
identification of plant pathogens, stress-related disorders, and pests.
The UNH-PDL is directed by the Cooperative Extension Plant Health specialist.
The UNH-PDL also serves as a resource for information, data, and examples utilized
for training and educational programs offered throughout New Hampshire and the
New England region. Educational training in the identification and management
of plant health problems is provided for Master Gardeners, Tree Stewards, Extension
Educators and Specialists, and different professional plant grower's.
What information is provided with the diagnosis?
Each completed diagnosis is returned with the identification of the causal agent
and information about the management of the disease, pest, or disorder. Management
recommendations stress the use of cultural, or non-chemical methods, but may
also include chemical recommendations when warranted.
Where is the Plant Diagnostic Lab located?
The UNH Plant Diagnostic Lab is affiliated with the Plant Biology Department
and is located on the UNH campus, 38 College Road, in Spaulding Hall, room G37. Click here for
written directions or here for a map.
Who may submit plant samples to the UNH-PDL?
Anyone growing or maintaining plants may submit samples to the UNH-PDL. Clients
include home gardeners, landscapers, golf course superintendents, arborists,
and commercial nursery, fruit, vegetable, and greenhouse operations. Although
the majority of the samples received by the UNH-PDL are from New Hampshire, out-of-state
submissions are also accepted.
How are samples submitted to the UNH-PDL?
Ideally, samples should include healthy, moderate, and advanced/severe examples
of the problem. The best samples include transition from health to diseased on
the same sample. Samples may be submitted directly to the UNH-PDL by mail or
'walk-ins,' or they may be submitted through the UNH Cooperative Extension offices
located in each of the ten New Hampshire counties. Samples may be mailed to:
The Plant Diagnostic Lab, Plant Biology Dept., G37 Spaulding Hall, UNH, Durham,
NH 03824. For additional information on submitting samples contact your county
Cooperative Extension office or call 862-3200.
Is there a fee for submitting samples to the UNH-PDL?
There is a $15.00 charge for samples submitted to the UNH Plant Diagnostic Lab.
A sample consists of one or several specimens of a single plant species (one
or several tomato plants would be a single sample; one tomato and one pepper
plant would be two samples). All samples should be accompanied by a Disease
Identification form (Available throughout the UNHCE county offices or by
calling 862-3200).
