carduus pycnocephalus medicinal uses
Deferring autumn grazing of sheep has been effective in reducing stand density because the thistles grow etiolated and less spiny when competing with ungrazed grasses. List-Based Rec., Soil Conserv. The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. Even with freezing temperatures during the daily cold period, germination was optimum if warm-period temperatures were from 5 to 20 C (Evans et al. : This plant is also on the Washington State quarantine list. stream Identification and characterization of major flavonoids and caffeoylquinic acids in three Compositae plants by LC/DAD-APCI/MS. It reduces the establishment of annual grasses and reduces the value of hay and other crops due to the blanketing effect of the overwintering rosettes, high rate and timing of germination, and its broad range of germination conditions. 2,4-D is lethal to 50% of tested animals (LD50) at 300-1000 mg/kg body weight and is classified as being of "little" to "some" hazard. Bendall (1974) describes a grazing control method that has proven successful in Australia: thistle-infested areas are closed to grazing in the fall when seedlings appear. It persists in the soil for 1-4 weeks. Optimum conditions for rust infection (18 to 20 C, 90 to 100% relative humidity) are likely to occur in autumn, in regions with a Mediterranean climate. 2007. Fl. /Length 9 0 R Summary 2 Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle, is a species of thistle.It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. Please enable it to take advantage of the complete set of features! Two fungi have been evaluated as agents on Italian thistle. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. Disclaimer. [8][9] Its tendency to grow under the canopy of oaks increases the risk of wildfire damage to the trees, as fire can more easily spread to the canopy. This weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex. Then sheep will graze the thistle along with the grass. >> This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). This species has been studied in depth by USDA entomologists as a natural enemy of musk thistle, but certainly should also be considered for importation into California for C. pycnocephalus control" (Goeden 1974). Cauline leaves are tomentose on the underside and contain spines on the . Carduus pycnocephalus is an annual herb that is not native to California. 1978). Carduus tenuiflorus Carduus acanthoide Carduus pycnocephalus Carduus nutans 1 of 4 2013 Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy.

Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Near streams or lakes particular cautions should be taken when using herbicides. A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. 1986. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). /Filter /LZWDecode Seed germination rate in Carduus pycnocephalus is very high, ranging between 83-96%. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. However, according to Charles Turner (1985) of the USDA Biocontrol Lab in Albany, California, it is possible that these insects may also prey on several of the endangered native thistles in the genus CIRSIUM. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. Seed germination rate in Carduus pycnocephalus is very high, ranging between 83-96%. Even with freezing temperatures during the daily cold period, germination was optimum if warm-period temperatures were from 5 to 20 C (Evans et al. Copyright 2017 Elsevier Ltd.

The chemical is noncorrosive and is generally considered nonharmful to wildlife. The seeds germinate at a wide variety of constant and alternating temperatures. In California, more than 40 species of indigenous or introduced phytophagous insects have adopted this alien weed as an alternate food-plant, at least 15 of which also find it a suitable reproductive host. /app/up/entry/73/th/22000.jpg:!0000 0000 0108 1272:!/app/up/mg/44/th/13398.jpg:!/app/up/entry/29/th/8868.jpg:!/app/up/cbo/248/th/74532.jpg:!/app/up/mg/280/th/mg84205-2.jpg:!/app/up/mg/185/th/mg55602-2.jpg:!/app/up/io/39/th/io11908-0.jpg:!/app/up/gp/78/th/15673.jpg:!/app/up/entry/90/th/27010.jpg:!0000 0000 1104 0321:! With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). C. pycnocephalus does not reproduce vegetatively, but its seeds are well equipped for dispersal by wind because of the large pappus and relatively small size. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. Nile and Mediterranean regions, eastern desert, and Sinai. Comments: It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). 1982). Leaf: basal 10--15 cm, 4--10-lobed; cauline +- tomentose. 2023. Leaves green and nearly hairless above and have cobwebby hairs below. One drawback is its long persistence in the soil, up to 18 months. Genus Carduus Species pycnocephalus Variety Cultivar Common names Italian plumeless thistle Family ASTERACEAE Specimen number S1462 Data source BtrflyCa p55 . For larger areas where the thistles are dominant, cultivation and cropping is a successful method of control provided a vigorous perennial pasture is established immediately after the cropping phase. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). macrocephalus (Desf.) [5][8] Check with local, regional, and national regulations directing use. Carduus pycnocephalus (Italian thistle) is a winter annual forb (family Asteraceae) that is native to the Mediterranean region of southern Europe, northern Africa, western Asia. High pH (6.5) also favors growth (Bendall 1975). Global Range: Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Bookshelf Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. Munz, P. A.

Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. HHS Vulnerability Disclosure, Help Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. C. pycnocephalus has been rapidly spreading on rangelands previously dominated by alien annual grasses (Evans et al. 2022 Mar;19(3):e202100827. The areas are then heavily grazed with sheep at more than twice the normal stocking rate. In California, more than 40 species of indigenous or introduced phytophagous insects have adopted this alien weed as an alternate food-plant, at least 15 of which also find it a suitable reproduc- tive host. -.

Italian thistle (Carduus pycnocephalus subsp. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. Though some Carduus species are known to accumulate nitrates in toxic quantities, C. pycnocephalus has apparently not been incriminated as a toxic weed (Goeden 1974). Jordon-Thaden and Louda (2003) and Barros et al. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Tropicos does not categorize distributions as native or non-native. Grubbing hoes must cut the plants 2 to 4 inches below ground level to prevent resprouting from dormant axillary buds.

Greuter analysed through phytochemical and biomolecular markers. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. Ants may also play a role in dispersing the seeds (Uphof 1942). It reduces the establishment of annual grasses and reduces the value of hay and other crops due to the blanketing effect of the overwintering rosettes, high rate and timing of germination, and its broad range of germination conditions. Stem: 2--20 dm, glabrous or slightly woolly, narrowly spiny-winged. Carduus pycnocephalus and C. tenuiflorus behaved as short-season annuals, C. vulgare and Onopordum showed a strongly biennial response, and the other species were annual except for C. nutans .

The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. The blanketing effect of overwintering rosettes can severely reduce the establishment of other plants, as the leaves of the rosette can become erect in dense stands (Parsons 1973). Even with freezing temperatures during the daily cold period, germination was optimum if warm-period temperatures were from 5 to 20 C (Evans et al. Free Amino Acids and Biogenic Amines Profiling and Variation in Wild and Sub-Endemic Cardueae Species from Sardinia and Corse. Several recent studies (Kok 1980, Trumble and Kok 1980a, 1980b) have shown that the weevil Rhinocyllus conicus is not adversely affected by field applications of 2,4-D.

For this method to be successful, the autumn grazing break is necessary so that vigorous growth of other plants is allowed to occur, forcing the thistles to grow tall and tender. [8] Mowing and slashing are not reliable as the plant is able to regrow and produce seed even at a height of 3 inches (7.6cm). This site needs JavaScript to work properly. Management Requirements: With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas.

The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973). They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). Since it is a nonselective herbicide, it must be carefully applied. In southern Europe, more than 80 species are associated with C. pycnocephalus; about one third of them are stenophagous and restricted to host plants belonging to the tribe Cynareae. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. The adults are foliage feeders, but more importantly the larvae mine crowns of rosettes and tips of expanding and expanded shoots, blasting the latter, and thus reduce the production of flowerheads. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. Other Common Names: Plymouth thistle, shore thistle Species Impact: Though some Carduus species are known to accumulate nitrates in toxic quantities, C. pycnocephalus has apparently not been incriminated as a toxic weed (Goeden 1974). Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. The necessity for constant monitoring is all the more important given this weed's potentially long seed dormancy period (to 8 years).

Carduus pycnocephalus can be distinguished from other thistle species by its relatively small and few terminal flowerheads and narrow phyllaries with copious tiny, firm, forward-pointing hairs, especially on the midrib (Hitchcock and Cronquist 1973). It is foliar absorbed and trans- located, making it effective in destroying the roots. 2,4-D ester should be applied when the thistles have a central stock height of no greater than 0.25 m (Wheatley and Collett 1981).
