How to Submit a Sample to the UPPDL
NOTICE: Our Lab Fees Have Changed
Please be aware that our lab fees have increased as of April 1, 2018. The new fee structure for mail and walk-in samples is as follows:
- Basic services (visual/microscopic examination, pest ID & management).
- This includes, but is not limited to, all turf grass samples (the UPPDL does not culture turf diseases) and arthropod (insect, spider, mite, etc.) identifications.
- Most samples submitted fall under "basic services".
- Basic services + disease culturing.
- Basic services + DNA/virus testing
Cash or check only; we do not accept credit cards. Make checks payable to the "UPPDL".
*Before submitting a sample for disease culturing ($15) or DNA/Virus testing ($30):
Contact our lab (435-797-2435 or firstname.lastname@example.org) or visit your local county Extension office to discuss the sample/issue. We do not test for all diseases so your sample should be pre-screened.
If you submit a sample for disease culturing, DNA or virus testing without contacting the lab prior to submission and we cannot perform the desired test, we will conduct the "basic services" listed above.
No refund for overpayment of testing services will be given.
List of What the UPPDL Does Not Test For:
Human pathogens or parasites
- We do not accept samples containing human skin, secretions, blood, etc.
- For these types of diagnostics please see your medical care provider.
- We do accept samples of ticks, bed bugs, fleas, bird mites, etc. collected from
the home or structure that are submitted in a vial containing ethanol or rubbing alcohol.
Verticillium for alfalfa export certification
Verticillium (with excpetions; please call prior to submitting)
Dutch Elm Disease
Bacterial leaf scorch
Fungi or pathogens in soil (we only test plant tissues, not soil)
Soil dwelling nematodes (we do test for plant-pathogenic nematodes)
Plant or soil nutrients (contact the usual.usu.edu for nutrient testing)
If we can not perform the desired testing, please contact one of the following labs for further assistance:
General Instructions for Submitting a Sample:
Complete the submission form (pdf format) and include with your sample. Additional information can be added to the back of the form; please indicate on the front of the form if you have written on the back.
Provide images via email, or printed and included with your sample.
- Type of images:
- Include a range of perspectives of the plant, turf area or damage, from close-up to over-all pictures of the yard or area of interest.
- We are interested in seeing the damage but equally interested in the surroundings (overall environment) of the plant and property, etc.
- Close-ups of dead grass or dead branches/leaves do not typically help with diagnosis.
Email images to email@example.com.
