OSU Nematode Testing Service - Submission

 

LABELING INDIVIDUAL SAMPLES

  • Each sample bag requires its own unique label.  Soil or plant material in separate bags will be processed as separate samples, unless otherwise noted. If sample bag contains both soil and roots in one bag, indicate on submission form what type of extraction you are requesting- soil, root, or both.
  • Plastic bags may be labeled on the outside with waterproof maker.  However, waterproof marker may abrade to illegibility during shipment, especially if samples leak soil or moisture.  To avoid label degradation, seal bags completely.
  • When using separate paper labels, double-bag each sample in plastic bags and put the label between the two bags. Paper in soil disintegrates.

INFORMATION TO ACCOMPANY COLLECTIVE SAMPLES

  • Include the nematode submission form or equivalent information in shipment with samples.
  • Supply your name, address, and phone, as well as site identification, current crop, and cropping history on either a Nematode Sample Submission Form or on another paper.  Please indicate if the invoice or a copy of the report is to be sent to another party. One submission form may be used for up to ten samples: use one line on the form for each sample. Enter soil and root samples on separate lines. Front (submission info) side of form may be photocopied). Do not rely on just the exterior mailing or return address label for sample identification.
  • Protect paperwork in a separate plastic bag to keep it safe from moisture damage and abrasion.
  • Avoid faxing or mailing the form separately from the sample if possible.

WILL YOU NEED SPECIES IDENTIFICATION?

We report plant-parasitic nematodes by genus (for example, Pratylenchus – lesion nematode – or Meloidogyne – root knot nematode) unless species identification is requested.  If requested, we report by species (for example, Pratylenchus penetrans or Meloidogyne hapla) for an additional fee.  Species identification may be helpful in assessing existing or potential nematode damage, because damage levels differ between both plant and nematode species.  However, in many cases species ID provides no additional management value.  Please indicate on the submission form if you want species identification. Phone (541) 737-5253 (lab) or (541) 737-5255 (Russ Ingham) with questions.
