Sample submission guidelines

Please note - This is a Teagasc client service only. We do not accept samples from the general public. The first step is to contact your Teagasc Advisor. Samples may be sent following consultation.

Sending samples by post

You can submit samples to the diagnostic service only by pre-arrangement with your Teagasc Advisor. Notice must be given that samples are being sent by your Advisor. Samples without any contact and background information (see guidance below), will not be processed. If advised to send samples directly to the plant clinic, they must be prepared and packaged as follows:

  • Pick a representative sample that is not too diseased (Whole plant is preferable, dead plants are not acceptable as an accurate diagnosis cannot be given).
  • Carefully dry the sample as best you can.
  • Wrap in brown paper or newspaper
  • Place in a sealed plastic bag

Post in an A4 sized padded envelope or suitably sized box to:
