Out-of-State Samples

NOTE: Due to personnel limitations under coronavirus prevention protocols, we are unable to accept out-of-state samples for disease diagnosis at this time, except in the Turfgrass Diagnostics Lab.

The NC State University PDIC has a USDA-APHIS permit to receive plant samples for disease diagnosis from elsewhere in the continental United States. This permit has specific requirements for documentation and packaging. In addition, we want samples to arrive in good condition for diagnosis. Out-of-state samples not properly packaged will be destroyed without examination.

Important: No live insects or other animals may be submitted from outside the state of North Carolina.

In addition to our packing and shipping instructions, please abide by the following:

  • Double-bag the sample.
  • Enclose a copy of the sample submission form with our permit number displayed at the top. If you are using a handwritten form that lacks the permit number, enclose a copy of the first page of the permit itself.
  • Place the sample in a sturdy cardboard box with all the seams taped closed. A paperboard envelope does not constitute adequate packaging.
  • You may use newspaper or bubble wrap to cushion the sample, but shredded paper and foam packing “peanuts” are discouraged.
  • Send the sample early enough in the week so that it is not in transit over the weekend.
