Notes for Plant sample submission:

  • Plant samples should be freshly collected and with a moderate amount of disease. Dead plants rarely yield an accurate diagnosis. Entire plants are preferred, especially if wilting symptoms are present. Place the roots in a plastic bag secured around the base of the plant and cover the top with another plastic bag, unsealed.  Place the sample in a sturdy box with crushed newspaper or other packing material. If only leaves or fruits are submitted, place them in zip-seal bags and box as above. Do not send samples in envelopes.
  • Any photographic or video images submitted shall become the property of The Ohio State University and may be used for educational or promotional purposes
