The UNH Plant Diagnostic Lab will not be accepting samples as of June 1, 2021
We appreciate your patience and cooperation during this time of transition, and appreciate your support for UNH Cooperative Extension.
The diagnostic services offered by the UNH Plant Diagnostic Lab include identification of plant pathogens, stress-related disorders and pests.
Please note: The lab is not able to test for pesticide residues or other contaminants.
The UNH-PDL provides diagnostic services for plant health issues to commercial producers and home horticulturists, landscapers and turf managers, arborists, and others in agriculture and the allied green industries.
The UNH Plant Diagnostic Lab will email (or send) a written report when a conclusion has been reached on the diagnosis or identification of the problem. Management recommendations (if applicable) will be included with the report. E-mail responses will come from firstname.lastname@example.org. Please be sure that e-mail from this address is not marked by your server as spam. All results are confidential.
The UNH-PDL is directed by the Cooperative Extension Plant Health Specialist and serves as a resource for information and materials for training and educational programs offered throughout New Hampshire and the New England region.
