The plant clinic serves as a clearinghouse for plant problems sent to the University of Illinois, from May through mid-September. Diagnoses are provided on field crops, trees, shrubs, turf, fruit, vegetables, or any other type of plant you can imagine. Specialists are called to help with diagnoses as needed and in an average year about 20 different specialists may have input on plant samples. Services include plant and insect identification; diagnosis of disease, insect, weed, and chemical injury symptoms (chemical residue testing not available); nematode assays; and help with nutrient-related problems, as well as management recommendations involving these diagnoses. The clinic cannot assess nutrient levels in tissue or soil samples.|
The University of Illinois Plant Clinic will be open from May 1 through September 15 this year. The clinic budget is supported in part by user fees. These fees have not changed since 1999 and are listed here. A check made payable to the University of Illinois must accompany each sample.
General diagnosis (including cultures) $12.50
Specialty tests (SCN, PWN, ELISA)* $18.75
Other nematodes (usually corn) $40.00
*SCN indicates the test for soybean cyst nematode. PWN indicates pinewood nematode analysis. ELISA is a technique used to test for various viral pathogens.
A specimen data form or equivalent information should always accompany a plant sample. As the saying goes, garbage in, garbage out. The ability to provide a thorough diagnosis is directly related to the quality of the sample and the type of information provided. Each of the University of Illinois Extension offices should have a copy of the specimen data form. You can also find the form in the Field Crop Scouting Manual, or you can access the form on the clinic website at http://www.cropsci.uiuc.edu/ research/clinic/clinic.html. There you will find information on clinic location, instructions on how to send a sample, a fee schedule, and more.
