Herbicide Resistance Testing Samples


  • Collect only mature, healthy seed from the suspect plants that have appeared to have survived the herbicide application.
  • A minimum of two thousand seeds per herbicide subgroup is required. When there is a need for several groups of herbicides to be tested, the number of seeds should be increased accordingly.
  • Seeds MUST be mature. Green or diseased seed will not germinate properly and will impede the diagnosis or make testing impossible.
  • Do not submit seed that has been treated with a pre-harvest herbicide (ex. glyphosate).
  • The sample MUST NOT contain any stems.
  • Seed should be clean with as little foreign material as possible.
  • Indicate the Herbicide Group(s) that you want to be tested.
  • Processing times may vary. We do not guarantee results before seeding.

Packaging and handling

  • Seeds MUST be dry before shipping. If your sample arrives mouldy or becomes mouldy during processing, it will not be tested.
  • To dry seeds, allow them to air dry for a few weeks on paper. Place them in a paper bag for shipment to the laboratory.
  • Ensure all sections of the Herbicide Resistance Testing Request Form are complete and submitted along with the sample.
  • Please note, the annual submission deadline is January 15 for weed seeds harvested during the prior year.
