MSU Plant & Pest Diagnostics provides plant health analyses and identification of nematodes, weeds, insects, and other arthropods.

Services and fees Submittal forms How to submit a sample

We assist a wide variety of people experiencing problems with plants and pests. Samples may be submitted to the lab by mail or dropped off at our facility. We will analyze the sample for a nominal fee and provide a diagnosis or identification of the problem as well as recommendations for control. However, please be aware that while we strive to diagnose plant health problems to the best of our abilities, there may be cases where a definitive diagnosis is not possible. In such instances, we will do our utmost to rule out potential causes and provide the most accurate information available. Your understanding and cooperation are greatly appreciated.
