carduus pycnocephalus medicinal uses

(eds. However, this weed does displace more desirable forage or cover plants. Italian thistle invades pastures and rangeland. C. pycnocephalus can germinate at a variety of soil depths. It crowds out more desirable forage, as well as native plants, and excludes livestock grazing where infestations are dense. 1981). Plants grow up to 20 dm, are often slightly woolly, and narrowly winged along stems and spined. subsp. 0 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. Carduus pycnocephalus Common Names: Italian thistle Evaluated on: 5/22/04 List committee review date: 08/07/2005 Re-evaluation date: Evaluator (s) John J. Knapp/ Invasive Plant Program Manager Catalina Island Conservancy P.O. Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973).

Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. 1980). Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). 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. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. 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. Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. One drawback is its long persistence in the soil, up to 18 months. [11] Puccinia cardui-pycnocephali is a species of rust (fungus) apparently exclusive to Carduus pycnocephalus. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977).

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. (Asteraceae), an endemic species of La Maddalena Archipelago (Sardinia--Italy). Chem Biodivers. [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. In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. Life cycle . These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) 9PA$R-T8K3!"m8!NFC 8Lfyp4Mk^.nau]boY@f1!($4F &h4.L1=T]eC[,`9ZCxh2 Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. 1979).

Carduus pycnocephalus is an annual herb that is not native to California. -. A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. On soils of naturally high fertility, thistle invasion can be expected at an earlier stage than on poorer soils. C. pycnocephalus can germinate at a variety of soil depths. Only 2-3 weeks should be required for control. Is this Weed Toxic?

World flora Family Compositae Genus . 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][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. Selective weed oils: There are several petroleum oils used for weed control. Biological control techniques for Carduus species have been extensively studied. 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. Catlogo de la Flora Vascular de Chile. Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. GERMINATION AND GROWTH. 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. Then sheep will graze the thistle along with the grass. The multiple stems are winged with spines. and transmitted securely. 1971, Baloch and Kahn 1973, Goeden 1974). Common names Italian plumeless thistle in . 1980). 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. cinereus - C. p . Dr. McHenry recommends using a flat-fan nozzle (Spraying Systems Co. #8003 or 8004 nozzle tip) rather than the cone nozzles available on most garden sprayers. Unauthorized use of these marks is strictly prohibited. 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. Drought favors a rapid increase in the thistle population. Insects that tested host-specific by the California Dept. The primary threat of this weed is its ability to dominate sites throughout California. Olympia, WA 98504-2560. hbbd```b``"o5 IDu0&IsNGR"Y:@$ 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). 3 Carpocoris mediterraneus.jpg 2,150 1,616; 1.79 MB C. bourgeanus-asp-2.jpg 2,448 3,264; 4.28 MB C. pycnocephalus-brcteas-1.jpg 3,121 2,342; 1.79 MB C. pycnocephalus-brcteas-2.jpg 2,048 1,536; 1.19 MB University of California Press, Berkeley.

Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." Gayana, Bot. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). The chemical is noncorrosive and is generally considered nonharmful to wildlife. Disclaimer. The primary threat of this weed is its ability to dominate sites throughout California. [8] Other rust species have been found on Italian thistle as well. [8][12][13], Grazing by sheep or goats (not cattle) in Australia has showed promise as well.[14]. Two fungi have been evaluated as agents on Italian thistle. Global Range: Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. 1979). Carduus speciesUnlike , Cirsium species have feathery, plumose pappus hairs (Douglas et al. Comments: It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). ), 2006-2023 California Invasive Plant Council. 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. Hand pulling, cultivation, and grazing are all effective control measures. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. 1979). Contact: Larry Serpa, Area Manager. The effects of prescribed fire on C. pycnocephalus also need investigation. Authors: Don Pitcher and Mary J. Russo, Global Invasive Species Team, The Nature Conservancy. Sheep selectively graze the tender thistles and will kill 90-95% of the weeds. 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. 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. University of California Press, Berkeley. Its spiny leaves, stems, and phyllaries prevent animals from grazing on it and nearby forage. L.Photo by G. Piper. Other Common Names: Plymouth thistle, shore thistle Italian thistle is a spiny annual or sometimes biennial that can grow 6 to 8 feet in height. 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. They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). endstream endobj startxref Were sorry, but GBIF doesnt work properly without JavaScript enabled.

Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. 1982 . The labels also give more precise information on mixing and safety precautions. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. Ex. CRUPY ). Tel. Tropicos does not categorize distributions as native or non-native. C. pycnocephalus can germinate at a variety of soil depths. The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). Observation: Carduus pycnocephalus L.

Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator. This site needs JavaScript to work properly. 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. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. This is partly due to its germination requirements and timing. Italian Plumeless-thistle - Italian plumeless thistle. 1. It survives best at low temperatures with short photoperiods (Kok 1979). official website and that any information you provide is encrypted 1982). 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). Syst. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. 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. Olympia WA 98504, P.O Box 42560 Weed class: A Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). 42: 1157. Nyman, Near streams or lakes particular cautions should be taken when using herbicides. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. 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). 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). National Library of Medicine Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus.

Naturalized as a weed. 1979). J Chromatogr B Analyt Technol Biomed Life Sci. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 1979). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). Chemical control can be achieved with a variety of products including: Clopyralid, glyphosate, Diquat, Picloram, and 2, 4-D ester. 1986. Epub 2006 Nov 2. 2019 Mar 9;15:23. doi: 10.1186/s13007-019-0408-x. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. S.

Grubbing hoes must cut the plants 2 to 4 inches below ground level to prevent resprouting from dormant axillary buds. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. Anonymous. pycnocephalus (L.) DC., 1838, Dissertao de mestrado. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). macrocephalus (Desf.) Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years). 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. Cauline leaves are tomentose on the underside and contain spines on the . (Goeden and Ricker 1978). Ready-to-Use Nutraceutical Formulations from Edible and Waste Organs of Algerian Artichokes. High pH (6.5) also favors growth (Bendall 1975). Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Box 2739 Avalon, CA 90704 (310) 510-1299 jknapp@catalinaconservancy.org Joseph DiTomaso University of California-Davis Jordon-Thaden and Louda (2003) and Barros et al. SEED DISPERSAL. Rhinocyllus conicus was first introduced into Canada in 1968 for the biological control of musk thistle (Carduus nutans L.) and plumeless thistle (Carduus acanthoides L.) (Harris and Zwolfer 1971). Italian thistle can facilitate fire spread and frequency by providing fuels in some habitats and creates monocultures that reduce native seedling recruitment and survival. Bookshelf : This plant is also on the Washington State quarantine list. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. 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 . 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. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). 1979). 3152 Paradise Drive, Room 101, Tiburon, CA 94920.
