Are burdock and cocklebur the same thing?

Cocklebur (far left): Annual plant that germinates and produces seed the same year. Burdock (left): Biennial (sometimes short-lived perennial) plant that germinates and spends the first growing season as a rosette, producing a flower stalk and seed the second growing season.

How is cocklebur dispersed?

A primary dispersal mechanism for spiny cocklebur is “hitchhiking” on animal fur or human clothing. The fruits float in water, and can also be effectively dispersed by water. Seeds can be spread by clinging to feedsacks or in contaminated hay.

How do you get rid of cockle burrs in your yard?

Apply a pre-emergent herbicide to the area in the spring, before the cockleburs come up. Some effective herbicides for cockleburs include Flumetsulam and Metribuzin. Use the herbicides appropriately, following the directions on the bottle. Mow over the new plants as soon as they come up.

How toxic is cocklebur?

Toxic principle: Carboxyactractyloside (CAT), sulfated glycoside, is the principle toxin in cocklebur plants. Clinical signs: Consumption of as little as 0.75% of body weight of cotyledonary portions can cause death, with clinical signs occurring a few hours post cocklebur sprout or seed ingestion.

Are Cockleburs poisonous to humans?

Although they might look and taste like sunflower seeds, cocklebur seeds should never be eaten! Carboxyatractyloside found in the seeds can cause abdominal pain, vomiting, low blood sugar, seizures, and even severe liver injury.

What would have happened if cocklebur fruit did not have hooks?

Each cocklebur fruit contains two seeds that may remain viable for many years. The prickly burs hook into your clothing and become tightly attached, like the Velcro® fasteners on shoes and day packs. Often the vicious burs form tangled clots in the fur of animals, and must be cut out of the hair.

How does xanthium look like?

The leaves are spirally arranged, with deeply toothed margins. Some species, notably Xanthium spinosum, are also very thorny with long, slender spines at the leaf bases. It is covered with stiff, hooked spines, which stick to fur and clothing and can be quite difficult to detach.

How do I get rid of cocklebur naturally?

The most effective methods of cocklebur control are hand pulling or chemical controls. Cocklebur plants reproduce easily by seed, which are generally dispersed on water. The seed can lie dormant in the soil for up to three years before ideal conditions cause it to germinate.

How do you control cocklebur?

Is Xanthium strumarium poisonous?

The mature plant is reported as non-toxic; although toxicity has been re- ported in cattle which had ingested mature plants with burs despite the general belief that ingestion of burs should be limited by mechanical injury during mastication. There are a few case reports about Xan- thium Strumarium poisoning in humans.

Where do cockleburs grow in the United States?

Today cocklebur seems to be over-insured. It is a common weed anywhere soil disturbance produces bare soils with poor drainage. The plant seems equally at home growing along scoured stream banks as it does roadsides and farm fields.

What kind of seed does a cocklebur plant have?

Cocklebur ( Xanthium strumarium or Xanthium spinosum) plants grow prickly fruit (burrs) that are spread easily by clinging to clothing and fur. Although it is hard to believe, the unfriendly-looking cocklebur is related to the sunflower and the daisy!

Can a cocklebur plant be harmful to humans?

Sadly, cocklebur can become the villain as its burs get hopelessly tangled in hair and fur. Also, every part of the plant is extremely toxic to mammals. This plant has caused many a death in both livestock and humans.

How long do cocklebur stay in the soil?

These long-lived seeds can sit in the soil for decades before they decide to germinate. Before humans, when disturbance regimes were a lot less hectic, this strategy likely assured that cocklebur would manage to stick around in any given area for the long term.
