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 On soils of naturally high fertility, thistle invasion can be expected at an earlier stage than on poorer soils. Life cycle . N5D#uD0qBsOb^g Stem: 2--20 dm, glabrous or slightly woolly, narrowly spiny-winged. Year Listed: 1991 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. 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. High pH (6.5) also favors growth (Bendall 1975). 1979). Identification and characterization of major flavonoids and caffeoylquinic acids in three Compositae plants by LC/DAD-APCI/MS. Where a presentation is not available, find more information by reading the abstract in the Cal-IPC Symposia Archive. The .gov means its official. Selective weed oils: There are several petroleum oils used for weed control. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). Carduus tenuiflorus Carduus acanthoide Carduus pycnocephalus Carduus nutans 1 of 4 2013 The plant has become an introduced species in other regions, and on other continents, often becoming a noxious weed or invasive species. Tropicos does not categorize distributions as native or non-native. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. 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). 1979). 1979). Carduus pycnocephalus reproduces only by seed. The seeds germinate at a wide variety of constant and alternating temperatures. g -pWQ /PzD`,|c4*#?x`(56A} Qf - After their introduction to See Canyon in southern California, the weevil destroyed 90% of the achenes and infested 91% of the capitula; however, the population of C. pycnocephalus did not decline (Goeden and Ricker 1978). Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). Italian thistle can grow densely, crowding out other vegetation with dense rosette 'colonies' in the winter, thereby preventing establishment of native plants. The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. Contact: Larry Serpa, Area Manager.

Olympia WA 98504, P.O Box 42560 It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. 3152 Paradise Drive, Room 101, Tiburon, CA 94920. Seeds buried 1.3 cm deep show the highest percentage emergence, whereas 20 to 25% of seeds buried 5 to 10 cm deep remain dormant. Italian Plumeless-thistle - Italian plumeless thistle. Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. Biological control techniques for Carduus species have been extensively studied. (Hawkes et al. APPLYING HERBICIDES: Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. Ethiopian traditional medi- . : This plant is also on the Washington State quarantine list. Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. Its spiny leaves, stems, and phyllaries prevent animals from grazing on it and nearby forage. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. Munz, P. A. Drought favors a rapid increase in the thistle population. Typing "Northwestern Sedge" return only 'Northwestern Sedge'. 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. See our Written Findingsfor more information about Italian thistle (Carduus pycnocephalus), Clark County NWCB Fact Sheeton Italian Thistle, 1111 Washington Street SE [7] It favors grasslands, woodlands, and chaparral vegetation types, but is especially prevalent in oak woodlands in and around the Central Valley. Cauline leaves are tomentose on the underside and contain spines on the lobe tips. It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. 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. S. Calif. 11086. Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. 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 . 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. Epub 2015 Sep 1. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. It survives best at low temperatures with short photoperiods (Kok 1979). It is foliar absorbed and translocated, making it effective in destroying the roots. 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. %%EOF It is found in disturbed areas, often with basaltic soils, fertile soils, or soils with a relatively high pH (> 6.5).[5][7]. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. 9PA$R-T8K3!"m8!NFC 8Lfyp4Mk^.nau]boY@f1!($4F &h4.L1=T]eC[,`9ZCxh2 Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973).

However, caution must be exercised when using these products, and their use is not always appropriate, especially near water surfaces and other sensitive natural habitats. The brown seeds do not usually dehisce from the seedheads, and this may be important in the establishment of these seeds in the seedbed litter (Evans et al. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). Flower heads typically occur in clusters of 2-5. 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 Circium. UFRGS,1-132,2020, Karlsson (2004-03-18 23:00:00) Frteckning ver svenska krlvxter, Monogr. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). Species of flowering plant in the daisy family Asteraceae. Since it is a nonselective herbicide, it must be carefully applied. The effects of prescribed fire on C. pycnocephalus also need investigation. (Asteraceae), an endemic species of La Maddalena Archipelago (Sardinia--Italy). The greatest diurnal fluctuation that supported optimum germination was 10 C for 16 hours and 35 C for 8 hours in each 24-hour period. 2,4-D can be used in combination with biological control measures to control Carduus. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). 1971, Baloch and Kahn 1973, Goeden 1974). 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). Flowers are purple. The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. All three species are unknown as artichoke or safflower pests, apparently only reproduce on Cadruinae, cause injury to vital plant parts at a critical growth stage of their host-plant (and thus appear capable of influencing the reproductive potential of C. pycnocephalus), and occur over a relatively wide geographic area. Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. The seeds start to germinate in the fall with the first effective rain. 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. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. b. 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. Careers. A variety of herbicides have been used on C. pycnocephalus, but they give only temporary control (Wheatley and Collett 1981). 437 0 obj <>/Encrypt 394 0 R/Filter/FlateDecode/ID[<6077C6EA8B98D0438538133787DC7747><7352E31CF2E5D44D8E07E3D1DB06B7BC>]/Index[393 71]/Info 392 0 R/Length 171/Prev 295012/Root 395 0 R/Size 464/Type/XRef/W[1 3 1]>>stream Before Olympia, WA 98504-2560.

Gard.,107(2):1154-1565,2008, USDA Natural Resources Conservation Service (NRCS) PLANTS Database (2021yx), https://plants.usda.gov/home/plantProfile?symbol=CAPY2. It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) >> subsp. Bossard, CC., J.M. Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). Seeds buried 1.3 cm deep show the highest percentage emergence, whereas 20 to 25% of seeds buried 5 to 10 cm deep remain dormant. In high fertility situations, using a roller to compact the soil is recommended during seedbed preparation (but not during seed sowing). Serv., U.S.D.A.

Management Programs: Carduus pycnocephalus is present on both the Ring Mountain and Jepson Prairie preserves in California, with Ring Mountain having the most significant infestation. Carduus pycnocephalus is an annual herb that is not native to California. Other Common Names: Plymouth thistle, shore thistle 1979). 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. cinereus - C. p . . Marengo A, Cagliero C, Sgorbini B, Anderson JL, Emaus MN, Bicchi C, Bertea CM, Rubiolo P. Plant Methods. To control by cutting, use a sharpened shovel at the top of the root crown. Marengo A, Maciel LS, Cagliero C, Rubiolo P, Herodes K. Plants (Basel). Carduus pycnocephalus reproduces only by seed. Unfortunately, half of the identified species of insects found feeding on C. pycnocephalus in southern California are also pests of cultivated plants, thus not good choices for biocontrol. 8 0 obj C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. The brown seeds do not usually dehisce from the seedheads, and this may be important in the establishment of these seeds in the seedbed litter (Evans et al. Additional research needs to be conducted on insects that can be used to control C. pycnocephalus and on the potential impact of these insects upon endangered native Cirsium species (Kok et al. Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. Genus Carduus is presented in Saudi Arabia by two species Carduus pycnocephalus and C. arabicus, they are widely spread in central, eastern and the northern . intermedius - C. p . The essential oil of the air dried aerial parts of Carduus pycnocephalus L. F. Asteraceae was prepared by hydrodistillation. University of Turin Instituional Repository AperTO. Because of this concern, their use has been somewhat limited. Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. However, this weed does displace more desirable forage or cover plants. Corollas are pink to purple, approx. [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). The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. Wb p General information about Carduus pycnocephalus (CRUPY) Western and central Europe, Mediterranean, Macaronesia, Caucasus, Western Asia, Himalayas. The combination of the two techniques discriminates the four species within the genus, giving further information on these little-investigated plants, traditionally used in the Mediterranean area and in Sardinia. Additionally, the root must be severed at least 4 inches (10cm) below the ground to prevent the plant from regenerating. 0 Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. BIOLOGICAL CONTROL. 2,4-D: 2,4-D is a phenoxy-type herbicide used for broadleaf weed control that works as a selective hormone or growth regulator. [8] Other rust species have been found on Italian thistle as well. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. 1972) and in 1973 to control C. pycnocephalus in southern California (Goeden and Ricker 1978). Epub 2022 Jan 27. 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. C. pycnocephalus can germinate at a variety of soil depths. Without management it cannot be eliminated and may completely carpet the site. %PDF-1.2 HHS Vulnerability Disclosure, Help 1982 . These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. % A winter annual, Carduus pycnocephalus stems range from 8 inches (20 cm) to 6.6 feet (2.0 m), and are glabrous to slightly wooly. 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. pycnocephalus NATURALIZED Habit: Annual. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. Authors: Don Pitcher and Mary J. Russo, Global Invasive Species Team, The Nature Conservancy. The effects of prescribed fire on C. pycnocephalus also need investigation. Fl. 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. 2,4-D can be used in combination with biological control measures to control Carduus. The following is a representative barcode sequence, the centroid of all available sequences for this species. Marticorena, C. & M. Quezada. Because of this concern, their use has been somewhat limited. 1979). It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) Carduus pycnocephalus Media in category " Carduus pycnocephalus " The following 141 files are in this category, out of 141 total. The primary threat of this weed is its ability to dominate sites throughout California. They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). 1985. Cal. ")\OYwoybSUU!U?7! xmY@P%i7"ri|? Ants may also play a role in dispersing the seeds (Uphof 1942). Epub 2006 Nov 2. The herbicidal use of oils depends on their chemical and physical properties. Unauthorized use of these marks is strictly prohibited. These thistles can be cultivated or manually removed when small. Denn pidvme tisce novch obrzk.

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). 2,4-D does not affect grasses. The multiple stems are winged with spines. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). 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). High pH (6.5) also favors growth (Bendall 1975). Spraying oil on thistle will be effective only if entire plants are coated. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Phenolic Composition of Inflorescences of Carduus nutans L. Intra-specific variation in the little-known Mediterranean plant Ptilostemon casabonae (L.) Greuter analysed through phytochemical and biomolecular markers.

Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. Carduus pycnocephalus, a vigorous annual thistle, arrived in California during the 1930s and has since become a serious weed problem. 1981). In southern Europe, all major parts of C. pycnocephalus plants are damaged by one or more insect species, whereas in southern California the thistles are relatively free of insect damage. Nkter pln zdarma, nkter za velmi nzk poplatek. [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. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. 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. The brown seeds do not usually dehisce from the seedheads, and this may be important in the establishment of these seeds in the seedbed litter (Evans et al. 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). It persists in the soil for 1-4 weeks. 2016;30(8):920-5. doi: 10.1080/14786419.2015.1079189. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. 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.

Italian thistle grows in dry, open area such as pastures, rangeland, right-of-ways, and waste areas. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. This is partly due to its germination requirements and timing. Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. Carduus species can be distinguished from native and introduced Cirsium species by their simple pappus hairs. Presentations are linked where available. pycnocephalus / Plymouth Thistle / Xewk tal-fjura gira. Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. Were sorry, but GBIF doesnt work properly without JavaScript enabled. When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. Sixteen edible plants from Southern Italy were evaluated for their in vitro antiproliferative properties, using the sulforodamine B (SRB) assay, on four human cancer cell lines: breast cancer MCF-7, prostate cancer LNCaP, amelanotic melanoma C32 and renal adenocarcinoma ACHN. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). Calflora: Information on California plants for education, research and conservation, with data contributed by public and private institutions and individuals, including the Consortium of California Herbaria. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. densiflora (Viv.) /Filter /LZWDecode 1979). It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 1979). Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. Only 2-3 weeks should be required for control. [web application]. It survives best at low temperatures with short photoperiods (Kok 1979). A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). C. pycnocephalus seeds are mucilaginous, unlike most other thistles. C. pycnocephalus has been rapidly spreading on rangelands previously dominated by alien annual grasses (Evans et al. Keywords: The greatest diurnal fluctuation that supported optimum germination was 10 C for 16 hours and 35 C for 8 hours in each 24-hour period.

Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). It is a host species for the introduced weevil, Rhinocilus conicus, which also attacks native thistles. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. 1979).
