Schedule of noxious weeds: Changes effective January 1, 2015

Effective January 1, 2015, amendments to the Schedule of Noxious Weeds, a regulation under the Weed Control Act, added nine weeds that are prohibited from growing where they will negatively affect agricultural land, crops or livestock.

The added weeds are:

  • common crupina
  • serrated tussock
  • wild chervil
  • jointed goatgrass
  • smooth bedstraw
  • wild parsnip
  • kudzu
  • tansy ragwort
  • woolly cupgrass

In addition, nine weeds have been removed. The weeds have been removed because they are no longer considered significant threats to agriculture and can be managed through modern management practices. These changes will help support pollinators.

The removed weeds are:

  • black-seeded proso millet
  • nodding thistle spp.
  • tuberous vetchling
  • goat’s beard spp.
  • Russian thistle
  • yellow rocket
  • Johnson grass
  • scotch thistle
  • wild carrot
