Plant & Weed Identification

The Department of Crops and Soil Sciences contracts with an expert in plant identification.  Weed/plant ID samples can be sent directly to the expert at Weed Science.

Samples submitted to the Plant Pest Diagnostic Clinic for identification will be forwarded to the above expert for identification, and the client will be informed of the identity of the plant via the Diagnostic Clinic. Weed control recommendations will not be given with identification.

Weed control information for the home gardener can be found on the WSU Extension Hortsense site. The Pacific Northwest Weed Management Handbook is one resource available to the commercial grower.
