The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Medicinal properties Medicinal parts Has medicinal uses no Do not self-administer no Do no use if pregnant no Legally restricted no Toxicity precautions Medicinal notes . Tel. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. The herbicidal use of oils depends on their chemical and physical properties. Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). "Larvae thought to be Ceutorhynchus trimaculatus were recovered from mines in crowns of C. pycnocephalus rosettes in central Italy, though only adults were positively identified as fairly consistent associates of this plant. densiflora (Viv.) (Asteraceae), an endemic species of La Maddalena Archipelago (Sardinia--Italy). Leaves green and nearly hairless above and have cobwebby hairs below. These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. The seeds germinate at a wide variety of constant and alternating temperatures. Brahmi-Chendouh N, Piccolella S, Gravina C, Fiorentino M, Formato M, Kheyar N, Pacifico S. Foods. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. APPLYING HERBICIDES: Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre.

J Chromatogr B Analyt Technol Biomed Life Sci. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. [7] It favors grasslands, woodlands, and chaparral vegetation types, but is especially prevalent in oak woodlands in and around the Central Valley. Italian thistle invades pastures and rangeland. This is the profile for the plant - Carduus pycnocephalus subsp. S. Calif. 11086. However, this weed does displace more desirable forage or cover plants. Please see WAC 16-752 for more information on the quarantine list. government site. Catlogo de la Flora Vascular de Chile. It is a host species for the introduced weevil, Rhinocilus conicus, which also attacks native thistles. CHEMICAL CONTROL. High pH (6.5) also favors growth (Bendall 1975). Two other rusts, Puccinia centaureae dc and Puccinia galatica Sydow are also reported to attack Carduus pycnocephalus, but their impact has not been researched (Batra et al. Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator. Carduus tenuiflorus Carduus acanthoide Carduus pycnocephalus Carduus nutans 1 of 4 2013 GERMINATION AND GROWTH. Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. Carduus pycnocephalus is present on both the Ring Mountain and Jepson Prairie preserves in California, with Ring Mountain having the most significant infestation. According to Wheatley and Collett (1981), hand-hoeing is effective for small patches, but make sure to sever the root a good 10 cm below ground level. Carduus pycnocephalus reproduces only by seed. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. pycnocephalus Name 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). Carduus pycnocephalus is a thistle that is native to the Mediterranean region and some other countries further north or east. Cauline leaves are tomentose on the underside and contain spines on the lobe tips. b. Italian thistlegrows in dry, open area such as pastures, rangeland, right-of-ways, and waste areas. The herbicidal use of oils depends on their chemical and physical properties. pycnocephalus NATURALIZED Habit: Annual. Management Research Needs: A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. GRAZING, Grazing by sheep, goats, and horses can be effective in control- ling thistles, but cattle are of little value (Parsons 1973). Please enable it to take advantage of the complete set of features! Carduus nutans L. Photo by California Department of Food and Agriculture 1981). Contact: Larry Serpa, Area Manager. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). Epub 2015 Sep 1. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. One drawback is its long persistence in the soil, up to 18 months. Comments: It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent.[2]. Communities: weed, characteristic of disturbed places, Search efloras.org (Flora of North America). 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. Disclaimer.

This has proven most effective during the spring and early summer. 2,4-D can be used in combination with biological control measures to control Carduus. It survives best at low temperatures with short photoperiods (Kok 1979). The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years). Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. High pH (6.5) also favors growth (Bendall 1975). Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. Without management it cannot be eliminated and may completely carpet the site. Marengo A, Cagliero C, Sgorbini B, Anderson JL, Emaus MN, Bicchi C, Bertea CM, Rubiolo P. Plant Methods. Spraying oil on thistle will be effective only if entire plants are coated. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. C. pycnocephalus germinates at temperature and moisture regimes and in seedbed environments which would inhibit the germination of the alien annual grass species that presently dominate California grasslands. 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. 1972) and in 1973 to control C. pycnocephalus in southern California (Goeden and Ricker 1978). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Selective weed oils: There are several petroleum oils used for weed control. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. Flower heads typically occur in clusters of 2-5. Italian thistle (Carduus pycnocephalus subsp. According to Wheatley and Collett (1981), hand-hoeing is effective for small patches, but make sure to sever the root a good 10 cm below ground level. Ex. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. Chemicals such as Picloram and 2,4-D may be of some use in controlling the weed, but an integrated management program involving a combination of techniques will prove most effective. 463 0 obj <>stream 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. Drought favors a rapid increase in the thistle population. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. & D. D. Keck. 11681. Bot. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." Two other rusts, Puccinia centaureae dc and Puccinia galatica Sydow are also reported to attack Carduus pycnocephalus, but their impact has not been researched (Batra et al.

List-Based Rec., Soil Conserv. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. High pH (6.5) also favors growth (Bendall 1975). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 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). The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. Due to the similarities of the two species, there may be more Turkish thistle near to where it has already been found that was misidentified as Italian thistle (Porter At a depth of 0.5-2.0 cm germination is highest, but some seeds germinate to a depth of 8 cm (Evans et al. %PDF-1.6 % Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. ; Flavonoids; HPLC-PDA-MS/MS; ITS sequence; PCR-RFLP. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." The following is a representative barcode sequence, the centroid of all available sequences for this species. 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. The plant has become an introduced species in other regions, and on other continents, often becoming a noxious weed or invasive species. Leaf: basal 10--15 cm, 4--10-lobed; cauline +- tomentose.

On soils of naturally high fertility, thistle invasion can be expected at an earlier stage than on poorer soils. The necessity for constant monitoring is all the more important given this weed's potentially long seed dormancy period (to 8 years). Chemicals such as Picloram and 2,4-D may be of some use in controlling the weed, but an integrated management program involving a combination of techniques will prove most effective. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. This is partly due to its germination requirements and timing. This weevil has been studied in depth as a candidate biological control agent by USDA entomologists and may be usefully employed against C. pycnocephalus and other Carduus species in North America in the near future" (Goeden 1974). Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. It is prohibited to transport, buy, sell, offer for sale, or distribute plants or plant parts of quarantined species into or within the state of Washington or to sell, offer for sale, or distribute seed packets of seed, flower seed blends, or wildflower mixes of quarantined species into or within the state of Washington. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. It persists in the soil for 1-4 weeks. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). http://creativecommons.org/licenses/by-nc/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, http://creativecommons.org/licenses/by/4.0/, Carduus tenuiflorus var. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). In the U.S. it is found in only a few parts of Texas and Arkansas but is rapidly spreading and "out of control" in most of California (Dunn 1976). Without management it cannot be eliminated and may completely carpet the site. Were sorry, but GBIF doesnt work properly without JavaScript enabled. They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks).
