carduus pycnocephalus medicinal uses

It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. GERMINATION AND GROWTH Seed germination rate in Carduus pycnocephalus is very high, ranging between 83-96%. It is foliar absorbed and trans- located, making it effective in destroying the roots. 1. Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. Native to: Northern Africa, Asia and Western and Southern Europe 1979). C. pycnocephalus can germinate at a variety of soil depths. Biological control techniques for Carduus species have been extensively studied. Tel. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). 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. subsp. 1981). Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. (You can unsubscribe anytime. Carduus pycnocephalus is a thistle that is native to the Mediterranean region and some other countries further north or east. This is partly due to its germination requirements and timing. pycnocephalus NATURALIZED Habit: Annual. SEED DISPERSAL. 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. . In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. 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. Development of an innovative and sustainable one-step method for rapid plant DNA isolation for targeted PCR using magnetic ionic liquids. 1982 . When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. (2019) identified these plants at Turkish thistle, Carduus cinereus. Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator. 42: 1157. Epub 2006 Nov 2. Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years). The primary threat of this weed is its ability to dominate sites throughout California. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. medicinal plants for their daily healthcare needs (Ojewole, 2004). High pH (6.5) also favors growth (Bendall 1975). eCollection 2019. Epub 2022 Jan 27. 1979). 1979). .4-.6 in (1-1.4cm) long, and the fruits are brown to gold, with a bristly, minutely barbed pappus. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Jordon-Thaden and Louda (2003) and Barros et al. Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent. ")\OYwoybSUU!U?7! xmY@P%i7"ri|?

It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 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. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). Carduus pycnocephalus is an annual herb that is not native to California. Olympia WA 98504, P.O Box 42560 Bethesda, MD 20894, Web Policies 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 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.

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. 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]. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. Carduus speciesUnlike , Cirsium species have feathery, plumose pappus hairs (Douglas et al. It survives best at low temperatures with short photoperiods (Kok 1979). The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973).

Clipboard, Search History, and several other advanced features are temporarily unavailable. 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). 1971, Baloch and Kahn 1973, Goeden 1974). Disclaimer. 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. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). J Chromatogr B Analyt Technol Biomed Life Sci. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Without management it cannot be eliminated and may completely carpet the site.

Authors: Don Pitcher and Mary J. Russo, Global Invasive Species Team, The Nature Conservancy. Italian thistle grows in dry, open area such as pastures, rangeland, right-of-ways, and waste areas. 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. [5][10], Biological control agents have limited success with Carduus pycnocephalus. C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. The effects of prescribed fire on C. pycnocephalus also need investigation. 2,4-D does not affect grasses. (415) 435-6465. %%EOF Hand pulling, cultivation, and grazing are all effective control measures. Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). [2][6] It is a C-listed weed by the California Department of Agriculture and a Moderate Invasive Plant rating by the California Invasive Plant Council. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). 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 These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). macrocephalus (Desf.) 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). 1978). Phyllary (flower head scale) margins are not scarious, unlike its close relative, C. tenuiflorus. APPLYING HERBICIDES: Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. 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. 1979). 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. 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 weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. 1979). No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. Randall, and M. Hoshovsky. The seeds start to germinate in the fall with the first effective rain. 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. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). official website and that any information you provide is encrypted Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. 8 0 obj & D.

They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). 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. 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. 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. C. pycnocephalus can germinate at a variety of soil depths. 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. Cal. GC/MS analysis revealed the presence of nineteen components . 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. 2022 Dec 7;11(24):3955. doi: 10.3390/foods11243955. government site. Fl. 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 grow densely, crowding out other vegetation with dense rosette 'colonies' in the winter, thereby preventing establishment of native plants. Each plant profile in the database contains nomenclature info, botanical data, plant description, large, high-resolution pictures, images and photos of the plants and its parts, detailed information such as uses, history . The plant has become an introduced species in other regions, and on other continents, often becoming a noxious weed or invasive species. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973).

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. It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. More information can be found by downloading our Written Findings. /Filter /LZWDecode Similarly, plants which are cut close to flowering time can produce seed on the cut portion. stream Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. 1981). Stem: 2--20 dm, glabrous or slightly woolly, narrowly spiny-winged. Plants grow up to 20 dm, are often slightly woolly, and narrowly winged along stems and spined. pycnocephalus Name 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.

Spraying oil on thistle will be effective only if entire plants are coated. A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). /Length 9 0 R 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. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. This is partly due to its germination requirements and timing. Ants may also play a role in dispersing the seeds (Uphof 1942). 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.

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. Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. This has proven most effective during the spring and early summer. Carduus pycnocephalus L.: Chile (South America)United States (North America). 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.

Wb p Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. Grubbing hoes must cut the plants 2 to 4 inches below ground level to prevent resprouting from dormant axillary buds. Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). 2019 Mar 9;15:23. doi: 10.1186/s13007-019-0408-x. 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. High pH (6.5) also favors growth (Bendall 1975). !Ct2eO@u%h&;4OL9%p=#$`05l6u+zL/=m=5gE+aSFWc$19#t30;`xePH41RcO5`+~+4/]Y. Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. Species descriptions and data provided by: 2012-2023. 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. Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973). Where a presentation is not available, find more information by reading the abstract in the Cal-IPC Symposia Archive. The labels also give more precise information on mixing and safety precautions. 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).

A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. Encyclopedia of Puget Sound is published by the Puget Sound Institute at the UW Tacoma Center for Urban Waters. University of California Press, Berkeley. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. Biological control techniques for Carduus species have been extensively studied. 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. Please see WAC 16-752 for more information on the quarantine list. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Italian thistle (Carduus pycnocephalus subsp. According to Goeden (1974), C. pycnocephalus serves as an . Seed dispersal by water and on animals and machinery is less important (Parsons 1973). J Chromatogr B Analyt Technol Biomed Life Sci. The multiple stems are winged with spines. This weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex. 1980). The plant grows in a rosettes of 10-14 inches (25-36 cm) in diameter, with four to ten lobed basal leaves that are 4-6 inches (10-15 cm) long. Munz, P. A. densiflora (Viv.) C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. 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). 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. It is foliar absorbed and translocated, making it effective in destroying the roots. The https:// ensures that you are connecting to the Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. Unauthorized use of these marks is strictly prohibited. It persists in the soil for 1-4 weeks. The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. We won't sell or give away your email address. 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. [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. 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.

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. (Asteraceae), an endemic species of La Maddalena Archipelago (Sardinia--Italy). 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. 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. 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). 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. 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.
