Holiday Hours

The lab will be closed November 24th-25th for the Thanksgiving holiday.  We will also be closed December 23rd-January 2nd for Christmas break.  Please plan accordingly and have samples submitted to the lab by December 19th.  We will resume normal business hours on January 3rd, 2023.  

MSU Plant & Pest Diagnostics is open for samples that are dropped-off or mailed to the lab.  Please avoid shipping samples on Fridays as packages are not delivered to campus on weekends.  When submitting plant samples, we encourage clients to email digital images to accompany the physical samples. Images can be sent to pestid@msu.edu.  

WE CANNOT ACCEPT MARIJUANA samples due to MSU compliance with federal policy.

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.
