carduus pycnocephalus medicinal uses
C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. University of Turin Instituional Repository AperTO. 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. Contact: Larry Serpa, Area Manager. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). Chemical control can be achieved with a variety of products including: Clopyralid, glyphosate, Diquat, Picloram, and 2, 4-D ester. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. Species descriptions and data provided by: 2012-2023. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). "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. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. 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. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. .

Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. 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). 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. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. The labels also give more precise information on mixing and safety precautions. 1986. 1980). National Library of Medicine Western and central Europe, Mediterranean, Macaronesia, Caucasus, Western Asia, Himalayas. Leaf: basal 10--15 cm, 4--10-lobed; cauline +- tomentose. 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. 8 0 obj Carduus nutans L. Photo by California Department of Food and Agriculture Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. Home | Contact | UW Privacy | UW Terms of Use. Disclaimer. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. Drought favors a rapid increase in the thistle population. Carduus pycnocephalus auct. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. ); U.S. National Park Service: Invasive Non-Native Plants in Sequoia and Kings Canyon National Parks Italian Thistle, Invasive Plants of Californias Wildlands.

CHEMICAL CONTROL. were analyzed and characterized by HPLC-PDA-MS/MS and PCR-RFLP of the nrDNA internal transcribed spacer (ITS). Hand pulling, cultivation, and grazing are all effective control measures. Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. 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. 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. 1979). Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. Bookshelf In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. 1982). 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. subsp. They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). 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 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 . 1979). Olympia, WA 98504-2560. The https:// ensures that you are connecting to the Selective weed oils: There are several petroleum oils used for weed control. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. It crowds out more desirable forage, as well as native plants, and excludes livestock grazing where infestations are dense. Bossard, CC., J.M. Chem Biodivers. Ethiopian traditional medi- . One drawback is its long persistence in the soil, up to 18 months. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. (You can unsubscribe anytime. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. Diagnostic Characteristics: Carduus pycnocephalus can be distinguished from other thistle species by its relatively small and few terminal flowerheads and narrow phyllaries with copious tiny, firm, One drawback is its long persistence in the soil, up to 18 months. This has proven most effective during the spring and early summer. 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).

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. 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. 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. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. 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. 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. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). 2,4-D does not affect grasses. We won't sell or give away your email address. Monitoring is needed to determine the effectiveness of any C. pycnocephalus control measures. Randall, and M. Hoshovsky. [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). 3)uowiF#o (:(#;C Flower heads typically occur in clusters of 2-5.

Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. 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. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 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). 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. ]KPTjcqD(fIV'.u;!W=:=4MC3AH}t[L72lHA^x`v]X[NC_;p ]&` The multiple stems are winged with spines. 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. Please enable it to take advantage of the complete set of features! subsp. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. Italian thistle can grow densely, crowding out other vegetation with dense rosette 'colonies' in the winter, thereby preventing establishment of native plants. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. arduus pycnocephalus L. Photo by A. Brousseau.

The primary threat of this weed is its ability to dominate sites throughout California. 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 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). 1979). A common name search of Northwestern Sedge matches 'Northwestern Sedge' and 'Northwestern Showy Sedge'. S. Calif. 11086. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. The effects of prescribed fire on C. pycnocephalus also need investigation. pycnocephalus (L.) DC., 1838, Dissertao de mestrado. It is foliar absorbed and translocated, making it effective in destroying the roots. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. 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). other members of the genus Carduus such as C. pycnocephalus have been reported to have potent antiinflammatory activity (Conforti et al., 2009). 1979). Nyman, Carduus pycnocephalus L., Carduus cephalanthus Viv.) Grapevine Green Pruning Residues as a Promising and Sustainable Source of Bioactive Phenolic Compounds. Jordon-Thaden and Louda (2003) and Barros et al. C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. 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). To control by cutting, use a sharpened shovel at the top of the root crown. 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. It has been introduced, presumably accidentally, to the USA, Australia, New Zealand and some other countries in Europe, Asia, Africa and South America. Accessibility The areas are then heavily grazed with sheep at more than twice the normal stocking rate. 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. Epub 2006 Nov 2. The seeds germinate at a wide variety of constant and alternating temperatures. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. This is partly due to its germination requirements and timing.

Then sheep will graze the thistle along with the grass. stream subsp. A variety of herbicides have been used on C. pycnocephalus, but they give only temporary control (Wheatley and Collett 1981). The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981).

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. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). 1979). The herbicidal use of oils depends on their chemical and physical properties. Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). 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). Wb p Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). This weevil mainly reproduces on certain thistles belonging to the Carduus-Silybumcirsium complex.

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. 1972) and in 1973 to control C. pycnocephalus in southern California (Goeden and Ricker 1978). APPLYING HERBICIDES: Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. Spraying oil on thistle will be effective only if entire plants are coated. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). Marengo A, Maxia A, Sanna C, Mandrone M, Bertea CM, Bicchi C, Sgorbini B, Cagliero C, Rubiolo P. Phytochemistry. [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. Italian thistle grows in dry, open area such as pastures, rangeland, right-of-ways, and waste areas. Comments: It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). 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 seeds germinate at a wide variety of constant and alternating temperatures.
