Plant Diagnostics Laboratory
We now offer two forms of payment – scroll down to Step 3 for payment options.
Diagnosis of plant problems is the first step in an effective and economic management program. We serve farmers, greenhouse producers, landscape contractors, turf managers, arborists, nurseries, and others in agriculture and the green industries. Each diagnosis includes a written report with pest management strategies that are research based, economically sound, and environmentally appropriate for the situation.
Please note: The lab is not able to test for pesticide residues, VOC’s, or other contaminants.
The UMass Extension Plant Diagnostic Lab will send a written report when a conclusion has been reached on the diagnosis or identification. Detailed management recommendations are included with diagnoses. All results are confidential.
To Submit a Sample:
Step 1 — Read Guidelines for Preparing Your Sample
Choose the type of test from the list in Step 2, and read the instructions on taking and preparing samples. Accurate diagnosis requires both a representative sample and sufficient information about the cultural practices and environmental conditions associated with the problem.
For proper diagnosis, specimens must be received in good condition.
Step 2 — Complete a Submission Form
A completed Sample Submission Form is required for each specimen. Submission forms for each test can be accessed at the links below.
There is a fee per specimen (or particular problem). The appropriate fee or proof of payment must accompany each sample.
By check: Enclose your payment with the sample. Make checks payable to the University of Massachusetts
By credit card: Enclose a copy of your credit card sales confirmation with the sample.
For proper diagnosis, specimens must be received in good condition. Hand-deliver samples if possible, or send them by the fastest means available. Include accompanying information (such as photos, etc.) regarding the symptoms that are of particular concern to you. Federal Express, UPS, and Priority Mail through the U.S. Postal Service deliver directly to the building.
Walk-ins, please note: Credit card payments are available online only. If you wish to pay by credit card, your online receipt must accompany your sample. Payment at the lab is by cash or check only.
