Sample Collection and Submission Instructions

The manner in which samples are collected, preserved, and submitted ensures a proper identification in a timely and efficient way.

Put as much information as possible on the sample submission form.  WRITE WITH A PENCIL OR PERMANENT INK PEN that will resist smearing. Pictures of the symptoms in the field will be very helpful in the preliminary analysis, and it can be E-mailed to the diagnostician.

  1. Place the sample submission form inside the zip lock bag.  The bag will protect the paperwork from damage.  Put the zip lock bag and the specimen inside the shipping container.
  2. Mail samples early in the week to avoid the weekend layover in the post office.
  3. For emergency samples, use overnight courier services or overnight mail.


  1. Submit generous amounts of plant material representing a range of symptoms.
  2. Do not add water or pack a sample that is wet.
  3. Keep samples refrigerated after collection until they are submitted.
  4. Do not mix samples in the same submission bag.
  5. Samples arriving from sites in Florida that are 2 days or less mailing time from Quincy, can be sealed in plastic bags for shipping.
  6. Samples arriving from distances greater than 2 days mailing time from Quincy should be packed tightly in a box with dry paper.  Do not seal in plastic because of the likelihood of sample deterioration during the mailing period.  Do not add moisture.

Turf samples should be collected near the margin of the affected area so that a range of diseased and healthy tissue is included. Two cup cutters plugs are usually sufficient. Send pictures of overall symptoms. Wrap samples in newspaper or paper towel before being sealed in a plastic bag.
