Since our inception in 1989, the Insect and Plant Disease Diagnostic Labs have served over 25,000 citizens. Inquiries arrive in the form of walk-ins, phone calls, e-mails, and regular mail. We operate year-round and offer diagnostic services to the public. Services include plant disease identification, plant nutritional and cultural problem assessment, insect identification, and insect injury identification. Maine’s Integrated Pest Management programs also make use of the labs for insect identification as well as plant disease diagnosis.

Important Announcement:

UMaine Extension is operating and some staff are working remotely, but the Tick Lab, Plant Disease Diagnostic Lab and Insect Lab can now accept samples. However, University of Maine Cooperative Extension buildings are CLOSED in an effort to ensure the health and safety of the community, and to help stem the spread of the coronavirus.  Please contact each lab prior to dropping off any samples:
