carduus pycnocephalus medicinal uses
S. Calif. 11086. Epub 2006 Nov 2. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. 2023 Jan 10;12(2):319. doi: 10.3390/plants12020319. Mechanical methods can be effective but must be done before the plant sets seed. This is partly due to its germination requirements and timing. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) This has proven most effective during the spring and early summer. 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. Common names Italian plumeless thistle in . Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). 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. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). [8] Other rust species have been found on Italian thistle as well. Species descriptions and data provided by: 2012-2023. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. MECHANICAL CONTROL. The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). Nile and Mediterranean regions, eastern desert, and Sinai. 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. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). [8][12][13], Grazing by sheep or goats (not cattle) in Australia has showed promise as well.[14]. Without management it cannot be eliminated and may completely carpet the site. Italian thistle (Carduus pycnocephalus subsp. Naturalized as a weed. Since it is a nonselective herbicide, it must be carefully applied. Bookshelf (Goeden and Ricker 1978). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. subsp. synonym auct. 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. This site needs JavaScript to work properly. 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.

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 . Spraying oil on thistle will be effective only if entire plants are coated. !Ct2eO@u%h&;4OL9%p=#$`05l6u+zL/=m=5gE+aSFWc$19#t30;`xePH41RcO5`+~+4/]Y. Phyllary (flower head scale) margins are not scarious, unlike its close relative, C. tenuiflorus. After 48 h of incubation the most antiproliferative plant extract was Cynara cardunculus ssp. C. pycnocephalus can germinate at a variety of soil depths. 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. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." 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).

Photo by A. Brousseau. Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. Database of the U.S.D.A., Beltsville. Plants grow up to 20 dm, are often slightly woolly, and narrowly winged along stems and spined. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. Brahmi-Chendouh N, Piccolella S, Gravina C, Fiorentino M, Formato M, Kheyar N, Pacifico S. Foods. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Flickr photos above were identified by the individual photographers but not reviewed by EoPS. macrocephalus (Desf.) 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. 1980). A common name search of Northwestern Sedge matches 'Northwestern Sedge' and 'Northwestern Showy Sedge'. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Sign up to receive information about Cal-IPC's upcoming events and project updates. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. ; Flavonoids; HPLC-PDA-MS/MS; ITS sequence; PCR-RFLP. See our postcardfor early detection information about Italian and slenderflower thistle. Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. Hand pulling, cultivation, and grazing are all effective control measures. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. Presentations are linked where available. Weed class: A GERMINATION AND GROWTH. 1959. Ethiopian traditional medi- . Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. 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. Tropicos does not categorize distributions as native or non-native. 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. Identification and characterization of major flavonoids and caffeoylquinic acids in three Compositae plants by LC/DAD-APCI/MS. 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). The weevil was released on infestations of Italian and slender-flower thistles at 16 sites in 11 counties in northern California during 1975-77 with establishment at most of the sites (Hawkes et al. It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). It has been introduced, presumably accidentally, to the USA, Australia, New Zealand and some other countries in Europe, Asia, Africa and South America. The seeds germinate at a wide variety of constant and alternating temperatures. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). 9PA$R-T8K3!"m8!NFC 8Lfyp4Mk^.nau]boY@f1!($4F &h4.L1=T]eC[,`9ZCxh2 2022 Mar;19(3):e202100827. Accessibility 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). 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. Carduus pycnocephalus reproduces only by seed. 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. stream C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. Drought favors a rapid increase in the thistle population. intermedius - C. p . C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). Please enable it to take advantage of the complete set of features! Keywords: 11681. 1971, Baloch and Kahn 1973, Goeden 1974). The herbicidal use of oils depends on their chemical and physical properties. The following is a representative barcode sequence, the centroid of all available sequences for this species. It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. >> Olympia, WA 98504-2560. 1979). Where a presentation is not available, find more information by reading the abstract in the Cal-IPC Symposia Archive. 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. 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). Additionally, the root must be severed at least 4 inches (10cm) below the ground to prevent the plant from regenerating.
