2017 Season at the University of Illinois Plant Clinic

Welcome to the 2017 Plant Clinic Season! We are open year round to serve your plant diagnostic needs.

Plant Clinic services include plant and insect identification, diagnosis of disease, insect, weed, and chemical injury problems (chemical injury on field crops only), nematode assays, and help with nutrient related problems, as well as recommendations involving these diagnoses. Microscopic examinations, laboratory culturing, virus assays, and nematode assays are some of the techniques used at the Plant Clinic. Many samples can be diagnosed within a few days. Should culturing be necessary, isolates may not be ready to make a final reading for 10-14 days. Nematode processing also requires 1-2 weeks depending on the procedure. We send your final diagnosis and invoice to you through both the US mail and email.

Please refer to our website at for additional details on samples, sample forms, fees, and services offered. If you have questions about what, where, when, or how to sample call us at 217-333-0519. When submitting a sample, please provide as much information as possible including the pattern of injury in the planting, the pattern on individual affected plants, and details describing how symptoms have changed over time to cause you concern. Pictures of the affected plants or areas can also be sent with the sample to give us a better idea of what is occurring in the environment.

Our fees vary depending on the procedure necessary. General diagnosis including culturing is $15, ELISA and other serological testing is $25, nematode analysis for SCN or PWN is $20, specialty nematode testing (such as corn) is $40. Checks should be made payable to the University of Illinois Plant Clinic. Please contact us if you are uncertain of which test is needed.
