Kill Poison Hemlock Now!
– Christine Gelley, Agriculture and Natural Resources Educator, Noble County OSU Extension
Poison hemlock has already emerged in a vegetative state around Noble County and beyond. Soon it will be bolting and blooming on stalks 6-10 feet tall. All parts of the plant are toxic to all classes of livestock if consumed and is prevalent along roadsides, ditches, and crop field borders.
It is a biennial weed that does not flower in the first year of growth but flowers in the second year. The earlier you can address poison hemlock with mowing and/or herbicide application, the better your control methods will be.
There’s Potential for Poisoning During Fall Grazing
– Jordan Penrose, Ohio State University Extension Agriculture and Natural Resources Educator, Gallia County (previously published in Farm & Dairy)
With fall fast approaching, it may be time to assess potential problems that could arise when livestock are grazing, such as trees and grasses. A good practice of walking or driving through your pastures will help you know what is growing in or around them.

Multiflora Rose Problems in Pastures? Control it Now!
Originally posted in the BEEF Cattle Newsletter, June 13, 2018– Dwight Lingenfelter, Penn State Extension Associate, Weed Science
As spring progresses, multiflora rose aggressively grows and eventually blooms in late May/early June. Several tactics can be used to control this problem weed and these methods will be briefly discussed.

Ohio Noxious Weed Identification – Week 18 Wild Mustard
Family: Mustard, Brassicaceae.
Habitat: Wasteland, roadsides, grain and other fields crops, primarily in northern Ohio.
Life cycle: Annual annual or summer annual.
Growth Habit: 1-2 feet high, branched and erect.
Leaves: Alternate, 2-7 inches long. Lower leaves have petioles and are irregularly lobed and toothed with bristly hairs; upper leaves are smaller and may not be lobed; petioles lacking or short.
Stem: Branched near top, bristly.
Flower: June – October. 1/2 inch, bright yellow, four-petal flowers borne in small terminal clusters.
Fruit: Slender, slightly curved, smooth seedpod about 1 inch long; borne on upper branches.
Similar plants: The yellow rocket looks similar but has rounded lower leaves that are more heart shaped.

Ohio Noxious Weed Identification – Week 17 Wild Carrot
Wild Carrot
Family: Parsley, Apiaceae.
Habitat: Dry fields, wastelands, pastures, and no-till field crops.
Life cycle: Biennial, forming a rosette the first year and producing flowers and seed in the second.
First Year Growth Habit: A basal rosette.
Second Year Growth Habit: 1-3 feet tall, branched and erect.
Leaves: Alternate, pinnately compound, finely divided and hairy.
Flowering Stem: Tall, hairy, stout, and branched.
Flower: June – October (second year). Small, lacy white 5-petaled flowers in flat-topped, umbrella shaped clusters with one dark reddish-brown flower in the center. Flower closes up and turns brown as it matures.
Root: Fleshy taproot.
Similar plants: Leaves have the appearance and odor of a garden carrot. Wild carrots taproot is not as large as the garden carrot. The plant also resembles poison hemlock (Conium maculatum). However, wild carrot has a hairy stem while poison hemlock has a smooth stem with purple blotches. The dark floret in the center of the inflorescence in second year and a distinctive carrot smell in the first year will also help distinguish this common weed.

Ohio Noxious Weed Identification – Week 16 Poison Hemlock
Poison Hemlock
Family: Parsley, Apiaceae.
Habitat: Wet sites, gardens, roadsides, wastelands, pastures, and meadows.
Life cycle: Biennial, forming a rosette the first year and producing flowers and seed in the second.
First Year Growth Habit: Basal rosette of finely divided leaves with a pungent odor.
Second-Year Growth Habit: 2-7 feet tall, branched plant with flowers.
Leaves: Alternate, pinnately compound, finely divided, toothed, and glossy green.
Stems: Branched, waxy with purple blotches; hollow between nodes and grooved.
Flower: June – August (second year). Clusters of small white flowers with 5 petals in a loose, umbrella-like cluster, 2-7” across.
Root: Fleshy taproot.
Similar plants: During the first year, poison hemlock resembles wild carrot, but has a strong, pungent odor. Further, young leaves of wild carrot are more finely divided and its stem is hairy. At maturity, poison hemlock can be difficult to distinguish from water parsnip and water hemlock. Look for purple blotches on the stem to identify poison hemlock. Water hemlock (Cicuta maculata), which is also highly poisonous, has a magenta-streaked stem and lanceolate leaflets with sharply-toothed edges. Water parsnip (Sium suave) is not poisonous and has toothed lanceolate leaflets.
The problem is….This plant is highly poisonous to both humans and animals. Poison hemlock is a large and impressive plant which has been planted as an ornamental in some areas. It grows quickly in fertile soils.
