From the Environmental Registry: Updating the Schedule of Noxious Weeds in Ontario

Regulation Proposal Notice: Updating the Schedule of Noxious Weeds in R.R.O. 1990, Regulation 1096 - General made under the Weed Control Act, R.S.O. 1990, c. W-5.

Description of Regulation:

The Weed Control Act and Regulation 1096 prohibit listed noxious weeds from being grown where they have the potential to negatively affect agricultural land. The list in the regulation’s Schedule of Noxious Weeds is outdated. Proposed revisions include the removal of nine weeds that are no longer considered to be significant threats to agriculture or horticulture in Ontario and the addition of nine new weeds that are considered emerging threats to the agriculture industry within Ontario.

Purpose of Regulation:

The Schedule of Noxious Weeds in Regulation 1096 includes nine weed species that are no longer considered to be significant threats to agriculture or horticulture in Ontario. Designating some of these plant species as noxious weeds may be in conflict with conservation initiatives, most notably the restoration and conservation of habitat to support pollinator health. The nine plant species can be managed through modern management practices upon farmed land.

It is proposed that the following species currently listed in the Schedule of Noxious Weeds under R.R.O. 1990, Regulation 1096 be removed:

1. Colt’s-foot (Tussilago farfara L.)
2. Dodder spp. (Cuscuta spp.)
3. Johnson grass (Sorghum halepense (L.) Persoon)
4. Black-seeded proso millet (Panicum miliaceum L. (black-seeded biotype))
5. Yellow rocket (Barbarea spp.)
6. Cypress spurge (Euphorbia cyparissias L.)
7. Leafy spurge (Euphorbia esula L. (complex))
8. Russian thistle (Salsola pestifer Aven Nelson)
9. Tuberous vetchling (Lathyrus tuberosus L.)

Removing some of the above weed species from the Schedule of Noxious Weeds would demonstrate support for sustaining biodiversity in Ontario. Some species, such as Colt’s-foot and yellow rocket, are also known to attract pollinating insects, such as bees.

The Schedule of Noxious Weeds in Regulation 1096 has not been subject to a comprehensive update for many years. Nine weed species have been identified that are considered to be emerging threats to the agriculture industry in Ontario. Some of the species recommended for addition have previously caused large losses in crop revenues in other jurisdictions (e.g., kudzu) and are of growing concern to Ontario farmers.

It is proposed that the following weed species are added to the Schedule of Noxious Weeds:

1. Smooth bedstraw (Gallium mollugo (L.))
2. Wild chervil (Anthriscus sylvestris)
3. Common crupina (Crupina vulgaris Cass.)
4. Jointed goatgrass (Aegilops cylindrical Host)
5. Kudzu (Pueraria lobata)
6. Wild parsnip (Pastinaca sativa)
7. Serrated tussock (Nassella trichotoma)
8. Tansy ragwort (Senecio jacobeae)
9. Wolly cup grass (Eriochloa villosa (Thunb.) Kunth)
These proposed changes would support initiatives related to invasive alien species control, biodiversity, and the environment.
