Diagnostic Clinic
The in-house plant pest diagnostic clinic utilizes visual diagnostics only. There is a $5 fee per insect, plant disease or plant identification sample, and a $7 fee per turfgrass/lawn sample. Forms can be requested from our office. PDF forms for samples are available below.
Most samples will be looked at within two business days. More difficult assessments require longer. Samples requiring growth in a moist chamber can take ten to fourteen days.
Fill out as much of the information as you can and send the sample to Ohio State University Extension, 9127 Miles Rd., Cleveland, OH 44105.
The quality of any diagnosis depends upon the quality of the sample. Please provide a generous sample which includes both infected and non infected tissues. A report will be sent via eMail or ground mail.
The ability to make a diagnosis often hinges on the quality of the sample and information provided. One leaf or a single squashed insect is not sufficient to provide a diagnosis. The best sample contains both infested and non-infested tissue.
