The Nematode Testing Service is devoted to our clients and will remain open until further notice. For the safety of all involved, we request that packages be sent via mail or express delivery, if at all possible. If samples must be delivered, please drop them off inside the bay of West or North loading docks* of Cordley Hall (map view). Please call us (541-737-5253) and leave a message that sample(s) have been dropped off and we will come get them.
* West & North Cordley Hall loading docks will be open to deposit samples from 10:00 a.m. to 4:00 p.m. (weekdays only).

These measures are being instituted to be in agreement with the University's policies, and to keep our customers and employees safe. We very much appreciate your cooperation!
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.
