Michigan State University Diagnostic Services was established in 1999 as a multi-disciplinary plant health and pest diagnostic facility.  Diagnosticians specializing in plant pathology, entomology, nematology and weed science work as a team to diagnose plant health and pest-related problems.  Our simple goal -- to provide a timely diagnosis of the problem and appropriate recommendations of control.

We accept samples from a wide range of clients, including growers, homeowners, nursery and landscape professionals, agribusiness specialists, pest control personnel, county extension and campus specialists, regulatory agencies, etc.

Samples submitted to the laboratory can be analyzed for the presence of insect pests, plant pathogens or nematodes.  Our weed scientist performs plant identifications and deals with herbicide related problems or issues.  We also offer testing for herbicide resistance and pesticide residue analysis.
