Submission tips

The labs offer the following tips on collecting and submitting samples:

  • Collect living plants that exhibit varying stages of decline.
  • Collect as much of the living plant as possible, several plants should be sent if feasible.
  • Do not submit dead plants.
  • For herbaceous plants, collect the entire plant, including as much of the root system as possible.
  • Dig out (dont pull) several symptomatic plants and shake excess soil from roots.
  • Bundle plants together and wrap roots only in a plastic bag, allowing stems and leaves to hang out of the bag.
  • Wrap the entire bundle of plants in newspaper and place it in a cardboard box.
  • Wrap mushrooms, roots, fruits and other soft, fleshy samples in a sturdy box. Most other samples can be placed in a plastic bag, which is loosely folded at the top, but not sealed.
  • DO NOT add moist paper towels or the specimen may decompose during shipping. If possible place several leaves in a flat paper envelope and the rest of the plant in the bag.
  • For nematode analysis, ship soil in plastic bags and keep refrigerated until shipped. It is important that nematode samples are not exposed to high temperatures. Specific guidelines for sample collection are available upon request.
  • For insect samples, send small specimens in a vial of alcohol; never in an envelope. Pack larger insects, such as moths, in cotton, in a sturdy box.
  • Ship samples immediately after collection. Ship samples by overnight delivery or mail early in the week to insure fast delivery. Plant samples often decompose if left in the post office over the weekend.
