Plant Clinic Opening

The University of Illinois Plant Clinic opens for the 2006 season on May 1. Hours are Monday through Friday, 8:00 to noon and 1:00 to 4:30. A large drop box sits outside the front door for depositing samples in the evening or on weekends. Specimen data forms are available in the drop box. For details about clinic services, sample submissions, and fees and to obtain forms and maps to the Plant Clinic, visit our Web site.

There is a fee for all plant clinic samples. These costs have not changed for several years. The fee schedule for 2006 follows:

General diagnosis, including cultures, plant, and insect ID

SCN or PWN*$18.75
ELISA tests*$25.00
Other nematodes (usually corn) $40.00

*SCN is the assay for soybean cyst nematode, including egg counts. PWN is pinewood nematode analysis. ELISA tests are specific serological tests. Call first (217-333-0519) if you are uncertain of available tests.

As in the past, payment must accompany any sample for diagnosis to be initiated. Checks should be made payable to the University of Illinois or to the Plant Clinic. Please do not send anything until May 1. Also keep in mind that the Plant Clinic is a laboratory meant to supplement your field diagnosis. Provide as much information with the sample as possible to obtain the most accurate diagnosis. If you have a specific test in mind, indicate that on the specimen data form (available on the Web site).

Several new ELISA tests (enzyme-linked immunosorbant assays) will be available in 2006. Details will appear in future issues of the Bulletin. If you have questions about testing services, please call the Plant Clinic; calls before May 1 will be redirected to Turner Hall.

The U of I Plant Clinic is a member laboratory of the north-central region of the National Plant Diagnostic Network (NPDN) and reports findings into the national database. Information about this network is available at Information about new pathogens, insects, and weed pests is disseminated through the NPDN. Two important diseases of current concern in Illinois are Asian soybean rust and Ramorum blight. Instructions for submitting suspect samples can be found on the Plant Clinic home page. Watch this site for updates on other pest problems as the season progresses.--Nancy Pataky
