Weed Identification Services
The WSU Small Grains team provides a weed identification service where your specimens from your small grains field may be identified by a professional weed science Extension specialist. There is no charge.
Weeds are identified by flowers and fruits/seeds. Leaves, stems, buds, and roots may also aid in identification.
Digital Identification Method:
Digital images may be taken by cell phone or digital camera, but the best method for creating digital images of your specimens is with a flatbed scanner. Please include a ruler, coin, etc. in your image for determining scale. Digital images of your specimen should be emailed to: email@example.com.
Physical Identification Method:
To submit a physical specimen, place the sample in a sealed zip-lock bag with a DRY paper towel and mail to: Small Grains Extension, Washington State University, PO Box 646420 Pullman, WA 99164-6420

- Your reason for concern e.g. invasiveness, curiosity, toxicity, etc.
