Plain language summary

Seed lots imported into Canada must be free of prohibited noxious weeds. Weed seeds mixed in with crop seeds or grain are one of the main pathways for unintentional introductionof invasive plants into any country. Seed purity testing is done by manually searching the seed sample for contaminating seeds which are then analysed morphologically for species identification. The process can be lengthy and the identification by seed analyst experts can sometimes be limited to the genus or family level.
