The University of Missouri Plant Diagnostic Clinic (PDC) has been serving Missouri since 1965. We assist county extension Specialists, commercial businesses, private farmers and growers and homeowners with their plant health problems. The PDC is capable of plant disease diagnosis and identification of unknown plants and insects (including arachnids). Besides clinic staff, a diverse group of Plant Sciences faculties specializing in agronomy, entomology, horticulture, and 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 labs, at your discretion, additional fees will apply.
