carduus pycnocephalus medicinal uses

Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). 1959. Mapping weeds and rare plants to inform management and conservation in the Zaca and Jesusita fires. Italian Plumeless-thistle - Italian plumeless thistle. Cal. << Seed dispersal by water and on animals and machinery is less important (Parsons 1973). National Library of Medicine synonym auct. hbbd```b``"o5 IDu0&IsNGR"Y:@$ %PDF-1.6 % The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. 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. The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. 1982 . According to Goeden (1974), C. pycnocephalus serves as an . An official website of the United States government. The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. macrocephalus (Desf.) C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). This is partly due to its germination requirements and timing. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. 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]. This is partly due to its germination requirements and timing. 1978). 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). This weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). Phytochemical analysis of non-volatile fraction of Artemisia caerulescens subsp. 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. Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator. Marengo A, Maxia A, Sanna C, Mandrone M, Bertea CM, Bicchi C, Sgorbini B, Cagliero C, Rubiolo P. Phytochemistry. 1981). 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. Repeated greenhouse inoculations of the rust on growing rosettes signif- icantly reduced the growth of C. pycnocephalus but not the number of florets (Oliveri 1984). Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. Hand pulling, cultivation, and grazing are all effective control measures. We suggest you upgrade to a modern browser. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al.

It persists in the soil for 1-4 weeks. Carduus pycnocephalus, a vigorous annual thistle, arrived in California during the 1930s and has since become a serious weed problem. It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. % The chemical is noncorrosive and is generally considered nonharmful to wildlife. Jordon-Thaden and Louda (2003) and Barros et al. (eds. Comments: It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). pycnocephalus (L.) DC., 1838, Dissertao de mestrado. Olympia, WA 98504-2560. Ants may also play a role in dispersing the seeds (Uphof 1942). 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. Free Amino Acids and Biogenic Amines Profiling and Variation in Wild and Sub-Endemic Cardueae Species from Sardinia and Corse. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). 1979). It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. [3], The plant grows in a rosettes of 1014 inches (2536cm) in diameter, with four to ten lobed basal leaves that are 46 inches (1015cm) long. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. Clipboard, Search History, and several other advanced features are temporarily unavailable. Tel. The seeds germinate at a wide variety of constant and alternating temperatures. Without management it cannot be eliminated and may completely carpet the site. PMC The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. Hand pulling, cultivation, and grazing are all effective control measures. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. GC/MS analysis revealed the presence of nineteen components . 393 0 obj <> endobj This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. Nile and Mediterranean regions, eastern desert, and Sinai. Near streams or lakes particular cautions should be taken when using herbicides. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. Biological control techniques for Carduus species have been extensively studied. Italian plumeless thistle, compact-headed thistle, Italian thistle, University of Alaska Anchorage, Alaska Natural Heritage Program, Washington State Noxious Weed Control Board, http://wiki.bugwood.org/index.php?title=Carduus_pycnocephalus&oldid=49872, Center for Invasive Species and Ecosystem Health at the University of Georgia, This page was last modified 15:09, 18 December 2013 by. 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. 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. 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. 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). 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. & D. D. Keck. In many of the countries where it has become naturalized it is . 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. Grapevine Green Pruning Residues as a Promising and Sustainable Source of Bioactive Phenolic Compounds. 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. >> Because of this concern, their use has been somewhat limited. 2016;30(8):920-5. doi: 10.1080/14786419.2015.1079189. 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. Species of flowering plant in the daisy family Asteraceae. Marticorena, C. & M. Quezada. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. Control of C. pycnocephalus requires active management once it becomes established in an area. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. Several management techniques appear promising, and integrated control operations involving a combination of practices need investigation. Stem: 2--20 dm, glabrous or slightly woolly, narrowly spiny-winged. University of California Press, Berkeley. 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. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). Carduus pycnocephalus L.: Chile (South America)United States (North America). It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. 2,4-D can be used in combination with biological control measures to control Carduus. 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). 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. 1979). Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. Grazing by sheep, goats, and horses can be effective in controlling thistles, but cattle are of little value (Parsons 1973). Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Is this Weed Toxic? L.Photo by G. Piper. 1974. Gard.,107(2):1154-1565,2008, USDA Natural Resources Conservation Service (NRCS) PLANTS Database (2021yx), https://plants.usda.gov/home/plantProfile?symbol=CAPY2. Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973). Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Fl. 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). Biological control techniques for Carduus species have been extensively studied. pycnocephalus NATURALIZED Habit: Annual. 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. The herbicidal use of oils depends on their chemical and physical properties. albidus - C. p . High pH (6.5) also favors growth (Bendall 1975). 1971, Baloch and Kahn 1973, Goeden 1974). ; Flavonoids; HPLC-PDA-MS/MS; ITS sequence; PCR-RFLP. The essential oil of the air dried aerial parts of Carduus pycnocephalus L. F. Asteraceae was prepared by hydrodistillation. (415) 435-6465. If there is reasonable ground cover during the late summer and autumn the thistle will not invade a site, but it will come in following overgrazing or creation of fire breaks (Parsons 1973). Monitoring is needed to determine the effectiveness of any C. pycnocephalus control measures. The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). subsp. 1981). Serv., U.S.D.A.

Federal government websites often end in .gov or .mil. SEED DISPERSAL 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. C. pycnocephalus can germinate at a variety of soil depths. stream The site is secure. It survives best at low temperatures with short photoperiods (Kok 1979). Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California. 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. 1985. Common names Italian plumeless thistle in . 1979). 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.

Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. 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. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. 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. 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. Ants may also play a role in dispersing the seeds (Uphof 1942). Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. endstream endobj startxref This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984).

The areas are then heavily grazed with sheep at more than twice the normal stocking rate. The https:// ensures that you are connecting to the Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). This weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex. 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. Were sorry, but GBIF doesnt work properly without JavaScript enabled.

It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 1971, Baloch and Kahn 1973, Goeden 1974). GRAZING, Grazing by sheep, goats, and horses can be effective in control- ling thistles, but cattle are of little value (Parsons 1973). 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). 0 Seeds are light brown to brown with veins, 0.18 to 0.24 inches (4 to 6 mm long), with hairs attache at one end. Only 2-3 weeks should be required for control. 2019 May;161:21-27. doi: 10.1016/j.phytochem.2019.02.005. 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. MeSH One drawback is its long persistence in the soil, up to 18 months. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. Communities: weed, characteristic of disturbed places, Search efloras.org (Flora of North America). C. pycnocephalus has been rapidly spreading on rangelands previously dominated by alien annual grasses (Evans et al. .4-.6 in (1-1.4cm) long, and the fruits are brown to gold, with a bristly, minutely barbed pappus. Caffeoylquinic acids; Carduus spp. Catlogo de la Flora Vascular de Chile.

Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. macrocephalus (Desf.) Tel. Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. 1980). Flowerheads narrow and in terminal clusters of 1 to 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. 1. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. Development of an innovative and sustainable one-step method for rapid plant DNA isolation for targeted PCR using magnetic ionic liquids.

Nyman, Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). The seeds germinate at a wide variety of constant and alternating temperatures. According to Goeden (1974), C. pycnocephalus serves as an alternative food-plant or breeding host to a diversity of phytophagous insects, most of which are euryphagous, ectophagous, sap- or foliage-feeding species. 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. Other Common Names: Plymouth thistle, shore thistle The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. 1979). Randall, and M. Hoshovsky. The plant has become an introduced species in other regions, and on other continents, often becoming a noxious weed or invasive species. "Larvae thought to be Ceutorhynchus trimacu- latus 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.

Knapp/ Invasive Plant Program Manager Catalina Island Conservancy P.O. In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Flower heads typically occur in clusters of 2-5. Since it is a nonselective herbicide, it must be carefully applied. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. 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. 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). The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974).

S. Calif. 11086. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. 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. Carduus pycnocephalus is present on both the Ring Mountain and Jepson Prairie preserves in California, with Ring Mountain having the most significant infestation. 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. Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. The primary threat of this weed is its ability to dominate sites throughout California. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. 1979). Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. [3][4][5], Carduus pycnocephalus has become a noxious weed in Australia, New Zealand, Macaronesia, South Africa, the Arabian Peninsula, South America, Hawaii, and North America, especially in much of California. It is most abundant in coastal areas and occurs as a weed of pastures, ranges, roadsides, rural areas, fallow cropland, railroad rights-of-way, field margins, and ditchbanks (Goeden and Ricker 1978). It is foliar absorbed and trans- located, making it effective in destroying the roots. 1979). of Agriculture and caused significant damage to the reproductive structures of the Italian thistle have not been utilized, due to concerns about possible predation of California's native thistle species. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Bot. University of Turin Instituional Repository AperTO. Leaf: basal 10--15 cm, 4--10-lobed; cauline +- tomentose. It is found in disturbed areas, often with basaltic soils, fertile soils, or soils with a relatively high pH (> 6.5).[5][7].
