Sample Submission Instructions

COVID-19 UPDATE (5/13/20)

The Rutgers Plant Diagnostic Laboratory is operational and processing samples received via shipment. (In accordance with University policy, we are not able to accept sample drop-offs at our building.)

Please email us directly for assistance—we are committed to doing all we can to help you with your plant health needs, including looking at physical samples. Campus buildings are locked and we cannot accept sample drop-offs. Carefully follow the directions below for sample submissions during this time.

  • Please contact us via email (richard.buckley@rutgers.edu and/or sabrina.tirpak@rutgers.edu) if you need further instructions for sample submissions.
  • See fee information, sampling instructions, and submission forms to accompany your physical sample.
  • Samples may be shipped via UPS or US Postal Service directly to our street address:

    Rutgers Plant Diagnostic Laboratory
    Ralph Geiger Turfgrass Education Center
    20 Indyk-Engel Way
    North Brunswick, NJ 08902
  • Please email us to inform us when to expect your sample—we will need to retrieve it from central campus mail services.
  • DO NOT send samples to PO Box 550, Milltown, NJ—they will not be able to be retrieved.
  • DO NOT try to leave samples outside of our building—the farm gates are locked and you will not be permitted entrance.
  • Emailed photographs are helpful when they accompany a physical sample, but we cannot make an accurate diagnosis or identification from a photograph alone.

Please return to this website to monitor lab status as the pandemic situation changes. Thank you for your patience as we deal with this unprecedented situation—we will do our best to minimize delays.
