Plant Pests and Diseases

At the main campus of Ohio State University there is a Plant and Pest Diagnostic Clinic (PPDC) that can help homeowners and horticulture industry stakeholders to diagnose potential problems with trees, shrubs, annual or perennial landscape plants and also LAWN and SPORTS TURF. 

For a FEE, individuals can mail a sample to Columbus (overnight shipping is required to preserve sample).  Certain criteria does apply to the quality and size of the sample.

PPDC will assess the sample for symptoms of fungal and bacterial pathogens or signs of insect or other pest damage.  A report will be returned with their findings.  Poor samples may reveal negative results.  If a cause is identified, instructions for correction will be shared, if solutions are available for the particular disease or pest identified.

Master Gardener Horticultural Hotline

Master Gardener Hotline is a FREE service provided to the community by trained volunteers of the Ohio State University.  The Master Gardener Volunteers of Medina are available to help homeowners with consumer-scale horticultural issues such as garden pests or garden diseases.  Volunteers work to research the potential plant problem and offer factsheets and information to improve plant health. However, we do not have a plant pathology lab on site.  If volunteers are unable to identify the problem, clients will be referred onto the PPDC Clinic (above) for further investigation at the client's expense.

The volunteers accept calls, photos, or walk-in samples on:

*TUESDAYS, April through October (*new day of the week)

9:00 A.M. to 12:00 P.M.

at the Medina Extension Office. 

Water Testing

OSU Extension does not collect nor analyze water samples at the office.

For well or cistern water that is used in the home for drinking and bathing, contact your local health department to discuss water sampling and testing. 

For concerns about chemical or mineral content in your water, you may contact a private lab approved by the Ohio Environmental Protection Agency (EPA) and arrange a sample.  Contact a few laboratories to compare prices.  Some water tests can be expensive depending on what you would like the water tested for.

Mineral / Rock Identification

OSU Extension does not identify rocks and minerals at the office.

The Cleveland Museum of Natural History has a Minerology Services Lab.  

From their site: "The Department of Mineralogy has a full-service petrographic laboratory where they can produce thin sections and polished sections with quick turnaround times. It also is equipped with a Zeiss Ultraphot and Nikon E400 POL microscopes. When the laboratory is in use for cutting rocks, visual identification of single rock or mineral specimens is offered free of charge. Phase identifications through thin section and/or XRPD are also available for a fee. Contact the curator for fees and to schedule an appointment."
