Plant Diagnostic Clinic

**Message to Plant Diagnostic Clinic Clients**

Due to personnel changes, we must temporarily suspend diagnostic services on horticultural and row crop samples at the University of Missouri Extension Plant Diagnostic Clinic, effective immediately, due to the departure of the Clinic Director. Disease diagnostic services for turf, led by Dr. Lee Miller, will continue to accept your turf samples. More information on submitting turf samples can be found at http://turfpath.missouri.edu.

You can find useful information on the National Plant Diagnostic Network web site at http://www.npdn.org/ including a listing of diagnostic clinics in other states. The plant diagnostic clinics at Purdue University and Iowa State University are among those that will accept your out-of-state samples. These and other clinic web sites include sample submission forms and other useful information.
