Seeds identification

The CFIA's Seed Program includes regulations restricting the presence of weed species in seed in an effort to prevent the introduction and spread of new weeds in Canada through seeds. Some weed species can invade agricultural and natural areas, causing serious damage to our economy and environment.

Tools for identifying weed seeds:

Weed seeds fact sheets

The Fact Sheets provide the user with images and descriptive information to aid in seed identification. Each fact sheet contains multiple seed images or drawings, feature descriptions, similar species comparisons and information on potential growth habitats and contamination sources for the plant species in question.
