Corollas are pink to purple, approx. 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. 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. Without management it cannot be eliminated and may completely carpet the site. C. pycnocephalus can germinate at a variety of soil depths. 1. Accessibility 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. See our Written Findingsfor more information about Italian thistle (Carduus pycnocephalus), Clark County NWCB Fact Sheeton Italian Thistle, 1111 Washington Street SE 1982 . Cauline leaves are tomentose on the underside and contain spines on the lobe tips. The chemical is noncorrosive and is generally considered nonharmful to wildlife. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. Caffeoylquinic acids; Carduus spp. 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. It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. A variety of herbicides have been used on C. pycnocephalus, but they give only temporary control (Wheatley and Collett 1981). 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. 1959. Presentations are linked where available. Naturalized as a weed. 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). Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. (Hawkes et al. Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. 1979). 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.

Tysice darmowych zdj i wektorw. A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). 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. GRAZING, Grazing by sheep, goats, and horses can be effective in control- ling thistles, but cattle are of little value (Parsons 1973).

It is foliar absorbed and trans- located, making it effective in destroying the roots. 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. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). !Ct2eO@u%h&;4OL9%p=#$`05l6u+zL/=m=5gE+aSFWc$19#t30;`xePH41RcO5`+~+4/]Y. 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. 1974.

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. Ants may also play a role in dispersing the seeds (Uphof 1942). A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. University of Turin Instituional Repository AperTO.

Leaf: basal 10--15 cm, 4--10-lobed; cauline +- tomentose. Note: This information is based on publications available through Tropicos and may not represent the entire distribution. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. [2] Flavonoids and caffeoylquinic acid derivatives were the predominant classes of secondary metabolites characterizing the extracts. Italian thistle (Carduus pycnocephalus subsp. Jordon-Thaden and Louda (2003) and Barros et al. 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 Missouri Botanical Garden, 4344 Shaw Boulevard, St. Louis, MO 63110 USA, http://creativecommons.org/licenses/by-nc-sa/3.0/, http://creativecommons.org/licenses/by-nc/3.0/, http://creativecommons.org/licenses/by/3.0/, Species of concern in the Puget Sound watershed, Marine invertebrates of Puget Sound and adjacent waters, Terrestrial vertebrates of the Puget Sound watershed, USGS: Nonindigenous Aquatic Species in Puget Sound, Washington Natural Heritage Programspecies lists. 3)uowiF#o (:(#;C Spraying oil on thistle will be effective only if entire plants are coated.

After 48 h of incubation the most antiproliferative plant extract was Cynara cardunculus ssp. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). 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. 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).

Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973). C. pycnocephalus seeds are mucilaginous, unlike most other thistles. 0 Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. The .gov means its official. Control of C. pycnocephalus requires active management once it becomes established in an area. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. List-Based Rec., Soil Conserv. 2019 Mar 9;15:23. doi: 10.1186/s13007-019-0408-x. Then sheep will graze the thistle along with the grass. On soils of naturally high fertility, thistle invasion can be expected at an earlier stage than on poorer soils. This has proven most effective during the spring and early summer. GERMINATION AND GROWTH. Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. 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. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts.

When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). macrocephalus (Desf.) 2019 May;161:21-27. doi: 10.1016/j.phytochem.2019.02.005.

A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent. Pobierz bezpatne zdjcia i wektory kolce oset. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. Seed germination rate in Carduus pycnocephalus is very high, ranging between 83-96%. Munz, P. A. macrocephalus (Desf.) Near streams or lakes particular cautions should be taken when using herbicides. 1979). 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. Contact: Larry Serpa, Area Manager. The labels also give more precise information on mixing and safety precautions. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. These thistles can be cultivated or manually removed when small. 1982). Without management it cannot be eliminated and may completely carpet the site.

It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 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). Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world.

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. Western and central Europe, Mediterranean, Macaronesia, Caucasus, Western Asia, Himalayas. The following is a representative barcode sequence, the centroid of all available sequences for this 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.
