Ohio noxious weeds

By: Peggy Kirk Hall, Wednesday, September 19th, 2018

New changes to Ohio’s prohibited noxious weeds list took effect last Friday, September 14th.  In a previous blog post, we explained that the Ohio Department of Agriculture (ODA) was considering an update to the list as part of a mandatory five year review of all administrative rules.  ODA ultimately added 13 new species to the list, and removed 3 species.

Added to the list of prohibited noxious weeds are:

  • 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).

Removed from the list are:

  • Wild carrot (Queen Anne’s lace) (Daucus carota L.).
  • Oxeye daisy (Chrysanthermum leucanthemum var. pinnatifidum).
  • Wild mustard (Brassica kaber var. pinnatifida).

Still on the list are:

  • Shatter cane (Sorghum bicolor).
  • Russian thistle (Salsola Kali var. tenuifolia).
  • Johnsongrass (Sorghum halepense).
  • Wild parsnip (Pastinaca sativa).
  • Grapevines: 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).
  • 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).

The revised list can be found online at Ohio Administrative Code § 901:5-37-01.  Readers may recall that the Farm Office’s Ag Law Library has a law bulletin on Ohio’s Noxious Weed Laws.  It has been updated to reflect the changes, and is available here.

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.

Noxious weed law questions are common in the midst of the growing season and this year is no different.  Below is a sampling of frequently asked questions we've received about noxious weed law.  Learn more about the laws in our new law bulletin, Ohio's Noxious Weed Laws, available here.

My neighbor doesn’t keep his fence row clear of noxious weeds.  What can I do about it?
First, talk to the neighbor.  If your neighbor doesn’t respond favorably, the second step is to provide a written notice to the neighbor stating that he has ten days to clear the fence row of the noxious weeds.  Third, if the neighbor still doesn’t take action, provide a written notice of the situation to the township trustees, which will initiate a process that could result in the trustees determining that there is a valid need to clear the fence row and hiring some to do the work.  Your neighbor will be legally obligated to pay for the costs on his property tax bill.

I’ve been notified by my township trustees that I have noxious weeds on my property.  What should I do?
Be aware that you must respond within five days of the date the trustees notified you about the weeds or the trustees will have the authority to destroy.  Your options are to destroy or cut the weeds or to provide information to the township trustees showing that there is no need to take action.  For example, such information might include showing that noxious weeds don’t exist on the property or showing that plants were incorrectly identified as noxious weeds.

Do I have to destroy my crop if noxious weeds are on my land?
No, Ohio law states that you must only “cut or destroy the weeds” if you have been notified by the township trustees that noxious weeds are on your property.  

Noxious weeds are growing in the road right-of-way. Can I remove them myself and charge the township for my costs? 
You may remove the noxious weeds, but you will probably not receive reimbursement for your costs unless the township trustees violated their duty to cut the weeds even after you followed the proper legal process for demanding their action.  Ohio law requires the township trustees to cut road right-of-way weeds in early June and August, in early September if necessary, and at other times if public safety is at issue.  If they fail to do so, you should formally complain to the township trustees in writing or by speaking at a township meeting.  If the trustees still fail to take action, the next step is to file a “writ of mandamus” action that asks the court to order the clearing.  Seeking reimbursement for your work prior to following this legal process is not the proper method for enforcing the township’s duty, according to the Second District Court of Appeals in Mezger v. Horton, 2013 Ohio 2964. 

How do I know which weeds are “noxious”?
The director of the Ohio Department of Agriculture conducts rulemaking to designate a plant as a prohibited noxious weed.  The list of plants that the director has formally designated as noxious weeds is in the Ohio Administrative Code and is available at http://codes.ohio.gov/oac/901:5-37-01
