DIAGNOSTIC SERVICES

We assist a wide variety of people experiencing problems with plants and pests. Our laboratory specializes in diagnosing many of the problems caused by arthropods (insects, mites, ticks, etc.), pathogens (fungi, oomycetes, bacteria, viruses), nematodes, and abiotic factors.

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.


WE CANNOT ACCEPT MEDICAL MARIJUANA SAMPLES DUE TO MSU COMPLIANCE WITH FEDERAL POLICY.
