The Forest Health Diagnostic Lab is committed to helping the citizens of New York resolve their troubles with insects and plants. We are available year-round to identify your insects, plants, and plant and tree diseases.

If you need something identified you can e-mail a digital image, bring or mail your specimen to the lab. The more information you can provide about the insect, plant or plant problem, the easier it will be for us to identify. There is no charge for this service.
