Berner, D. K., et al. Canada thistle (note that it's NOT 'Canadian' thistle) is in the family Asteraceae. This mechanism has only been observed in pistillate plants for dioecious C. arvense. [19] Florivores such as Beetles and Grasshoppers are commonly seen as well. Every plant species has a unique floral fragrance composition. This was seen in both natural plants emitting the fragrance and emitting the scent synthetically. – Creeping thistle, California thistle Scientific name: Cirsium arvense L. Family: Asteraceae (Sunflower family) Description Origin: Eurasia and North Africa. [20] This is thought to be the result of additive and synergistic effects from the blend increasing the attraction to the plant. Few of the popular common names of the plant are Creeping thistle, Field thistle, Californian thistle, Canadian thistle, lettuce from hell thistle, corn thistle, cursed thistle, field thistle, green thistle, hard thistle, perennial thistle, prickly thistle, small-flowered thistle, way thistle, Cardo cundidor, Choussio, Ciji, Da khawarak azghai, Honghuamiao, Ohtja, Koygocerten, Koygocuren, Ohakas, Perticone, … Mowing: Mowing just before flower buds open can stop the development of Canada thistle seeds. (When we first moved here, the place was overrun with thistles. European thistle naturalized in United States and Canada where it is a pernicious weed (同)creeping thistle, Cirsium arvense a nation in northern North America; the French were the first Europeans to settle in mainland Canada; "the border between the United States and Canada … Many herbicides registered in fruit crops may burn back the top growth of the weed, but do very little to suppress the extensive root system. Legal status: Canada thistle is considered a noxious weed in 46 states including Indiana. [22] It is believed that general arousal can be stimulated through exposure of a single compound, whereas the accumulated exposure of all the compounds influence the foraging behaviour of the butterflies. [2][3][4][5] The standard English name in its native area is creeping thistle. This is regulated through a regulatory feedback mechanism depending on the pollination status of the plant. Life Cycle Perennial General Description A rhizomatous perennial with lobed, spiny leaves and pink flowers. Applying herbicide: Herbicides dominated by phenoxy compounds (especially MCPA) caused drastic declines in thistle infestation in Sweden in the 1950s. Growing forages such as alfalfa can help control the species as a weed by frequently cutting the alfalfa to add nutrients to the soil, the weeds also get cut, and have a harder time re-establishing themselves, which reduces the shoot density. Shoots can also arise from the lateral buds on the underground portion of regular shoots, particularly if the shoots are cut off through mowing or when stem segments are buried.[17]. [46], The feathery pappus is also used by the Cherokee to fletch blowgun darts. Scientific Name Cirsium arvense (L.) Scop. More seeds are produced when male and female plants are closer together, as flowers are primarily insect-pollinated.

It is a non-native invasive species from Europe, and landowners with Canada thistle on their property are obligated to take measures to control it. Canada Thistle a.k.a. [12] The C3 plants originated during Mesozoic and Paleozoic eras, and tend to thrive in areas where sunlight intensity is moderate, temperatures are moderate, and ground water is plentiful. field thistle. Seedlings: Cotyledons are oval to round and pale green in color. Many weeds in perennial fruit crops are controlled during site preparation, but can become problematic again after crop establishment. [31], The species is widely considered a weed even where it is native, for example being designated an "injurious weed" in the United Kingdom under the Weeds Act 1959. – Creeping thistle, California thistle Scientific name: Cirsium arvense L.

Depending on the fruit crop grown, cool-season crops like cereal rye can be planted in row middles in the late summer/early fall and will compete with Canada thistle as it emerges in spring. The rust species Puccinia obtegens has shown some promise for controlling Canada thistle, but it must be used in conjunction with other control measures to be effective. Considered noxious under the BC Weed Control Act General Description • Erect herbaceous perennial 1.5 – 4’ tall with extensive creeping rootstock • Stems are branched, slightly hairy, ridged Leaves • Prickly, 2 - 8” long • … [18] the fragrance that C. arvense emits attracts both pollinators and florivores containing compounds that attract each respectively. Cirsium arvense is a perennial species of flowering plant in the family Asteraceae, native throughout Europe and western Asia, northern Africa and widely introduced elsewhere. Canada Thistle produces flowers from about June until August. [23][24][25] One to 5 flower heads occur per branch, with plants in very favourable conditions producing up to 100 heads per shoot. It also was a top producer of nectar sugar in a 2016 study in Britain, with a second-place ranking due to a production per floral unit of (2609 +/- 239 μg). [38] However, use of this weevil has had a damaging effect on other thistle species as well, include some that are threatened. [27][28][29], The flowers are visited by a wide variety of insects such as bees, moths, wasps and beetles[30] (the generalised pollination syndrome). Control: Often multiple types of control measures are needed. Scientific name: Cirsium arvense Despite being considered a 'weed' of cultivated ground, the seeds of the Creeping thistle provide an important food source for farmland birds, many of which are declining rapidly. Canada thistle control is difficult but the following info may help. It it also different from other native North American species given its large roots and multiple small flower heads on a branched stem, Its underground structure consists of four types, 1) long, thick, horizontal roots, 2) long, thick, vertical roots, 3) short, fine shoots, and 4) vertical, underground stems. Class A Noxious Weeds Common name Scientific name African rue Peganum harmala Canada thistle … If you bring hay on-farm, use a reliable source. Biological controls: There are limited options. [14] Each head contains an average of 100 florets. [15], GIven its adaptive nature, Cirsium arvense is one of the worst invasive weeds worldwide. Looking at certain butterflies species, it can be seen that the fragrance blend is highly attractive to them, being sensitive to their antennae. [13], Creeping thistle is a herbaceous perennial plant growing up to 150 cm, forming extensive clonal colonies from thickened roots that send up numerous erect shoots during the growing season. [1], The Canada thistle is part of the Cirsium genus, in the subtribe Carduinae, trube Cardueae and family Astreracae. Fragrance emission increases with age.

Canada thistle grows in a variety of habitats with full or partial sun and is often found in disturbed areas such as roadsides, trails, pastures, and recently flooded areas. The taproot is considered the most nutritious part. Cirsium arvense is a C3 carbon fixation plant. Differences can be seen in their R-protein mediated defenses, sensitivities to abiotic stresses and developmental timing. It differs from other species in the same genus given its dioecious flowers. [32] It is also a serious invasive species in many additional regions where it has been introduced, usually accidentally as a contaminant in cereal crop seeds. Common Name(s): Canada Thistle Scientific Name: Cirsium arvense (L.) Scop. Nonnative honeybees are shown to have the highest visitation rate, following other bee species such as halictus and lasioglossum. Scientific Name: Cirsium arvense (L.) Scop. Other Names Creeping thistle, perennial thistle, and green thistle. Plants systemically diseased with the rust gradually but surely die. Exclusion and sanitation: Avoid spreading thistle roots, shoots, and seeds by implements such as mowers between fields. Herbicides: There are essentially two herbicide strategies. It is an invasive weed native to Europe and Asia. This plant and the related entity italicized and indented above can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. As mentioned earlier, they thrive in disturbed soils.) Biological Control 67:350-360. [37] One larva of the species can consume up to 95% of seeds in a particular flower bud. Reproduction: By seeds carried up to 1/2 mile by wind and through adventitious shoots that develop from root buds. [16] Though asserted in some literature, creeping thistle does not form rhizomes. It is unclear if the government continues to use this weevil to control Canada thistles or not. [47], "Cursed thistle" redirects here. Canada thistle is a perennial thistle that grows 1.5-5 ft. tall, and is distinguished from other thistles by its extensive lateral root system, dense clonal growth, an Altervista Flora Italiana, Cardo dei campi comune, Acker-Kratzdistel, åkertistel. [21], The fragrance contains several compounds that attract diverse insects. Perhaps one of the most noxious weeds in the home garden, Canada thistle has a reputation for being impossible to get rid of. [34], Orellia ruficauda feeds on Canada thistle and has been reported to be the most effective biological control agent for that plant. Biological Control 86:28-35. http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200023656. Reductions in thistle density were estimated, in 10 sites in the U.S., Greece, and Russia, to average 43%, 64%, and 81% by 18, 30, and 42 months, respectively, after a single application of spores of the fungus.[43]. [17] The seeds are 4–5 mm long, with a feathery pappus which assists in wind dispersal. Thickets of thistle crowd out forage grasses in pastures and rangelands, reducing crop yields and productivity. Introduced into the United States around 1750. [18], The inflorescence compound cyme is 10–22 mm (0.39–0.87 in) in diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). It was introduced to North America in the 1600s, probably in agricultural seed shipments and is now widespread throughout the United States and Canada. If tillage is used as the primary method of control, it should be done often and deeply to deplete root reserves. Berner, D. K., et al. Control methods include cutting at flower stem extension before the flower buds open to prevent seed spread. Legal status: Canada thistle is considered a noxious weed in 46 states including Indiana. Cultivation/plowing: Cultivation may be used during site preparation and early crop establishment. [26] Creeping thistle foliage is used as a food by over 20 species of Lepidoptera, including the painted lady butterfly and the engrailed moth, and several species of aphids. View all resources. Scientific Name: Cirsium arvense (L.) Scop., Other Names: chardon des champs, Canadian thistle, Creeping thistle, Field thistle, chardon du Canada Family: Composite or Aster Family (Compositae) General Description: Perennial, reproducing by seed and by horizontal roots which produce new shoots, often forming dense patches. Canada thistle. Through comparison of its genetic expressions, the plant evolves differently with respects to where it has established itself. Spring is here and with it comes the emergence of weeds- especially problematic perennials like Canada thistle (Figure 1). Scientific name: Cirsium arvense (L.) Scop. Control Canada thistle in roadsides, field roads, and fencerows. Tillage is not a stand-alone treatment. The species spreads by creeping roots which in turn causes Canada thistle to … creeping thistle. Invasive and Problem Plants of the United States: Kay, Q. O. N. (1985).

Using multiple mowings, one at bud stage and one targeted toward fall regrowth, will help deplete root energy reserves. Other Names: Creeping thistle, perennial thistle, and green thistle. Growth habit: Deep-rooted and colony-forming perennial. Canada thistle, Cirsium arvense Asterales: Asteraceae - EDDMapS Repeated cutting at the same growth stage over several years may "wear down" the plant. Use tested seed when planting row middles to minimize the risk of contamination with weed seeds (Figure 2). [45] Bruichladdich distillery on Isle of Islay lists creeping thistle as one of the 22 botanical forages used in their gin, The Botanist. High antennal response are seen in consequence to the phenylacetaldehyde as well as the terpenes (oxoisophoroneoxide, oxoisophorone, and dihydrooxoisophorone) found in the blend. Bull thistles (Cirsium vulgare) are exactly that – bullish. Introduced into the United Hermaphrodites and subhermaphrodites in a reputedly dioecious plant. P-anisaldehyde is found in less than 1%, yet it attracts pollinators such as honey bees. Average seed production per plant has been estimated at 1530. Consider a combination of the following: © 2020 Purdue University | An equal access/equal opportunity university | Copyright Complaints | Maintained by Facts for Fancy Fruit. The leaves are very spiny, lobed, and up to 15–20 cm long and 2–3 cm broad (smaller on the upper part of the flower stem). Generally, new shoots begin to form in January. [44], Like other Cirsium species, the roots are edible, though rarely used, not in the least because of their propensity to induce flatulence in some people. Hover flies are also commonly seen pollinating the flower heads of this plant. Scientific name: Cirsium arvense (L.) Scop. Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. [citation needed] The leaves are also edible, though the spines make their preparation for food too tedious to be worthwhile. The stalks, however, are also edible and more easily despined. [12] MCPA and clopyralid are approved in some regions. This type of herbicide application is sometimes referred to as a “chemical mowing”. [14] According to Flora of Northwest Europe[23] the two varieties are: The Biology of Canadian Weeds: Cirsium arvense[14] list four varieties: The seeds are an important food for the goldfinch and the linnet, and to a lesser extent for other finches. Cover crops: There is some evidence that shows cover crops can be useful for suppressing Canada thistle growth. [14] The plant can bloom from seed in a year then subsequently the seeds produced can emerge in the following year.[2]. Glyphosate is a non-selective herbicide that can be used when the plant has grown a few inches tall, where the herbicide can be absorbed by the leaf surfaces. In Canada, C. arvense is classified as a primary noxious weed seed in the Weed Seeds Order 2005 which applies to Canada's Seeds Regulations.[33].
