2012 Season at the University of Illinois Plant Clinic

What a fantastic start to the 2012 season, the 37th year of operation of the University of Illinois Plant Clinic. Samples have already been arriving as the unusually warm weather has inspired early field work, plant growth, and observations of pest issues. The Plant Clinic began operating year-round last fall, when we moved to a new location in Turner Hall on the south end of the Urbana campus. During the winter our business hours are reduced, but on Monday, April 30, we will resume full-day hours of 8 a.m. to noon and 1 to 4:30 p.m.

One of the new Plant Clinic diagnostic labs in Turner Hall.

Our services include plant and insect identification; diagnosis of disease, insect, weed, and chemical injury (chemical injury on field crops only); nematode assays; and help with nutrient-related problems. We also offer recommendations involving all these issues. Some of the techniques we use are microscopic examination, laboratory culturing, virus assays, and nematode assays. Many samples can be diagnosed within a day or two, though should culturing be necessary, it may be as long as two weeks before isolates are ready for a final reading. Nematode processing also requires 1 to 2 weeks depending on the procedure. We send you final diagnoses and invoices through both U.S. mail and email. If you provide your email address on the sample form, you will get your information earlier.

Please refer to our website ( for additional details on sampling, sample forms, fees, and services. If you have questions about what, where, or how to sample, call us at 217-333-0519 during business hours. (As the university transitions to a new phone system, we should even have voicemail by mid-June.) Whenever submitting a sample, provide as much information as possible on the pattern of injury in the planting, the pattern on individual affected plants, and details of how symptoms have changed over time to cause you concern.

Our fees vary depending on the procedure required for diagnosis. General diagnosis including culturing is $15; ELISA and immunostrip testing are $25; nematode analysis for SCN or PWN is $20; specialty nematode testing (such as corn) is $40. For us to begin diagnosis, payment must accompany your sample. Make checks payable to the University of Illinois or to the Plant Clinic. If you are not sure which test is needed, call us.

To send a sample by U.S. mail or a delivery service, use this address: University of Illinois Plant Clinic, 1102 S. Goodwin, S-417 Turner Hall, Urbana, IL 61801.

To drop off a sample at S-417 Turner Hall: Park in the metered lot F28 on the east side of Turner or at the ACES library metered lot on the west side of Turner. Come in the south door. Take the elevator in the southeast corner of the building to the 4th floor. Turn left when you exit the elevator; we are in the southeast corridor. If we are temporarily away from the office, use the green dropbox located just outside our door.
