Current sample

The University of Missouri Plant Diagnostic Clinic (PDC) has been serving Missouri since 1965.  We assist county Extension Specialists, commercial businesses and private citizens with their pest problems. The PDC is capable of plant disease diagnosis (including turfgrass), identification of unknown plants and insects (including arachnids). Besides clinic staff, a diverse group of Plant Sciences faculty specializing in agronomy, entomology, horticulture, or plant pathology assist with identification of pests as needed. The clinic is open year round to receive samples. 

The PDC does not test plant nutrient levels, soil characteristics or identify nematodes. Samples submitted to the clinic requiring these tests can be forwarded to the respective lab, at your discretion, additional fees will apply.

The Plant Diagnostic Clinic provides identification and management solutions in a written report for:

  • Plant Disease 
  • Turfgrass Disease 
  • Plant/Weed Species 
  • Insect/Mite Species
