The Turfgrass Pest Diagnostic Lab evaluates samples for turfgrass diseases.

This service is designed for managers of high quality turfgrass such as athletic fields and golf courses. The primary difference between our service and other similar services is a rapid turnaround time and the direct involvement of turfgrass diagnostic experts. For this reason, it is always important to call PRIOR TO SENDING samples to make sure that the lab is accepting samples.

The price for in-state samples is $100 and $150 for out-of-state samples.

Disease Sample Submission Guidelines

  1. Submit generous amounts of plant material from the edge of the diseased area representing a range of symptoms (part dead part healthy). Two cup cutter plugs are usually sufficient. Aeration cores are not.
  2. Don't add water. Samples should be wrapped in aluminum foil, newspaper, paper towel, etc. Do not place samples in plastic bags. Ensure that soil is secure and not able to mix with turfgrass tissues during the shipping process.
  3. Deliver or ship samples via express courier immediately after collecting. Do not send samples if collected more than 12 hrs prior to shipping. Get new samples.
  4. All samples must be accompanied by any other pertinent information related to the issue. Images can help as well and should be uploaded here .
  5. Samples cannot be received on Saturday or Sunday; ship accordingly.
  6. Dr. John Kaminski is the Penn State faculty contact overseeing this service. You may contact Dr. Kaminski's Lab to advise when samples have been sent or for questions regarding this form and service.
