Ohio Agricultural Law Blog--Changes made to Ohio's prohibited noxious weeds list
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.
