Sample Submission Guidelines
The Rapid Turfgrass Diagnostic Service (RTDS) is offered by the Institute of Food and Agricultural Sciences (IFAS), University of Florida in conjunction with the Cooperative Extension Service. The service is now available by request to turfgrass managers outside the United States. Samples must be pre-approved and must be accompanied by shipping labels and permits provided by The Florida Extension Plant Diagnostic Center (FEPDC) staff. Contact clinic staff at PDC@ifas.ufl.edu or Dr. Harmon to request instructions and forms.
- 1. Submit generous amounts of plant material from the edge of the diseased area representing a range of symptoms (part diseased part healthy). Two cup cutter plugs are usually sufficient. Aeration cores are not.
- 2. Don’t add water. Samples should be sealed in plastic bags and may be wrapped in aluminum foil, newspaper, paper towel, etc before being sealed in a plastic bag.
- 3. 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 the international submission form and shipping labels sent to you upon request as pdf files. Give complete information on the form and keep the form separate from the sample. Limit sample information to one (1) sample per form. You are encouraged to include any other pertinent information in addition to that requested on the form.
- 5. Samples cannot be received on Saturday or Sunday; ship accordingly.
- 6. Dr. Phil Harmon is the UF faculty contact overseeing this service. You may contact Dr. Harmon to advise when samples have been sent or for questions regarding this form and service.

The primary role of the RTDS is to determine if the plant dysfunction involves an infectious causal agent, e.g. fungus, bacterium or virus. This is done by associating causal agents with symptomatic plant tissue.
The RTDS does not routinely test water or soil for plant disease causal agents.
- 1. All plant samples should originate within the geographical boundaries of the contiguous 48 states or be accompanied by appropriate USDA/FDACS plant importation permits.
- 2. Plant samples must be adequate in quality and quantity and be accompanied by this completed form or equivalent information. Obtaining the appropriate sample before submission will save both time and shipping expense. NOTE: FEPDC staff are required by law to immediately destroy samples from outside the US that are not accompanied by our permit and shipping label.
- 3. Samples must be accompanied by payment to insure timely release of disease determinations and recommendations. Clientele can arrange for monthly invoicing by contacting FEPDC staff if Clinic usage is five (5) or more times per month. We accept and prefer Visa or Mastercard payment.
- 4. Samples are processed on a first come first served basis in most cases.
- 5. Plant disease determinations and associated control options are direct mailed, emailed or sent by FAX.
