Wild carrot, Oxeye daisy, and wild mustard will no longer be prohibited noxious weeds in Ohio if the Ohio Department of Agriculture’s (ODA) revisions to the noxious weeds list become effective. ODA is proposing to remove the three plants after its five year review of plant species considered “noxious” for purposes of Ohio law. The agency is also proposing adding these 12 species to the noxious weeds list:

  • Yellow Groove Bamboo (Phyllostachys aureasculata), when the plant has spread from its original premise of planting and is not being maintained.
  • Field bindweed (Convolvulus arvensis)
  • Heart-podded hoary cress (Lepidium draba sub. draba). Hairy whitetop or ballcress (Lepidium appelianum)
  • Perennial sowthistle (Sonchus arvensis)
  • Russian knapweed (Acroptilon repens)
  • Leafy spurge (Euphorbia esula)
  • Hedge bindweed (Calystegia sepium)
  • Serrated tussock (Nassella trichotoma)
  • Columbus grass (Sorghum x almum)
  • Musk thistle (Carduus nutans)
  • Forage Kochia (Bassia prostrata)
  • Water Hemp (Amaranthus tuberculatus)

The director of ODA has the legal authority to designate noxious weeds. Several Ohio laws provide for control and removal of designated noxious weeds along public highways, toll roads, and railroads, and on private property.  The current noxious weeds list also contains the following plants, which will remain on the list:

  • Grapevines: (Vitis spp.), when growing in groups of one hundred or more and not pruned, sprayed, cultivated, or otherwise maintained for two consecutive years.
  • Canada thistle (Cirsium arvense L. (Scop.))
  • Poison hemlock (Conium maculatum)
  • Cressleaf groundsel (Senecio glabellus)
  • Musk thistle (Carduus nutans)
  • Purple loosestrife (Lythrum salicaria)
  • Mile-A-Minute Weed (Polygonum perfoliatum)
  • Giant Hogweed (Heracleum mantegazzianum).
  • Apple of Peru (Nicandra physalodes)
  • Marestail (Conyza canadensis)
  • Kochia (Bassia scoparia)
  • Palmer amaranth (Amaranthus palmeri)
  • Kudzu (Pueraria montana var. lobata)
  • Japanese knotweed (Polygonum cuspidatum)

ODA is requesting public comments on the revised list of noxious weeds through April 27, 2018. E-mail comments to ecomments@agri.ohio.gov or mail them to Legal Section, Ohio Department of Agriculture, 8995 E. Main St., Reynoldsburg, Ohio 43068. Learn more about noxious weed laws in our bulletin, here.
