Life cycle . 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. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. [2] Carduus pycnocephalus L.: Chile (South America)United States (North America). 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. Contact: Larry Serpa, Area Manager. 1980). A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). 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). Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Biological control techniques for Carduus species have been extensively studied. 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. g -pWQ /PzD`,|c4*#?x`(56A} Qf - Flowers are purple. Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. Italian thistle is a spiny annual or sometimes biennial that can grow 6 to 8 feet in height. 1. Where does it grow? Gayana, Bot. 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. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). 42: 1157. Epub 2006 Nov 2. Marticorena, C. & M. Quezada. Repeated greenhouse inoculations of the rust on growing rosettes significantly reduced the growth of C. pycnocephalus but not the number of florets (Oliveri 1984). Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. The chemical is noncorrosive and is generally considered nonharmful to wildlife. N5D#uD0qBsOb^g Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). po114543:!null:!po60488:!po23271:!cbo74532:!mg84205:!mg55602:!io11908:!gp15673:!gp15673:!null:!

The seeds start to germinate in the fall with the first effective rain. Control of C. pycnocephalus requires active management once it becomes established in an area. Free Amino Acids and Biogenic Amines Profiling and Variation in Wild and Sub-Endemic Cardueae Species from Sardinia and Corse. 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. 2,4-D does not affect grasses. Keywords: 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. A variety of herbicides have been used on C. pycnocephalus, but they give only temporary control (Wheatley and Collett 1981). Denn pidvme tisce novch obrzk. 2016;30(8):920-5. doi: 10.1080/14786419.2015.1079189. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). Would you like email updates of new search results? The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). Sheep selectively graze the tender thistles and will kill 90-95% of the weeds. 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 . This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). %PDF-1.6 % After 48 h of incubation the most antiproliferative plant extract was Cynara cardunculus ssp. [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. Biological control agents, particularly the weevil Rhinocyllus conicus and the rust Puccinia Carduii-pycnocephali, show considerable promise in controlling C. pycnocephalus. 0 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 mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. 1978). Ornano L, Venditti A, Donno Y, Sanna C, Ballero M, Bianco A. Nat Prod Res. It is foliar absorbed and translocated, making it effective in destroying the roots.

World flora Family Compositae Genus . 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. See our Written Findingsfor more information about Italian thistle (Carduus pycnocephalus), Clark County NWCB Fact Sheeton Italian Thistle, 1111 Washington Street SE Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. Herbicides can be applied uniformly over an area (for large infestations) or by spot spraying only the individual plants. SEED DISPERSAL. 0[ W d A$WXDHm@,[W DJ_gm "=a*mH. bg3_]@ Q$T5'^ (Hawkes et al. 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. Carduus nutans L. Photo by California Department of Food and Agriculture 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. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. [8][12][13], Grazing by sheep or goats (not cattle) in Australia has showed promise as well.[14]. carduus Carduus pycnocephalus var. hbbd```b``"o5 IDu0&IsNGR"Y:@$ 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. The necessity for constant monitoring is all the more important given this weed's potentially long seed dormancy period (to 8 years). To control by cutting, use a sharpened shovel at the top of the root crown. official website and that any information you provide is encrypted Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. The effects of prescribed fire on C. pycnocephalus also need investigation. Native to: Northern Africa, Asia and Western and Southern Europe [3], Flower heads are 2-5 per cluster, densely matted with cobwebby hairs at the base of the phyllaries and spiny towards the tips. Hand pulling, cultivation, and grazing are all effective control measures. Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. 9PA$R-T8K3!"m8!NFC 8Lfyp4Mk^.nau]boY@f1!($4F &h4.L1=T]eC[,`9ZCxh2 endstream endobj 394 0 obj <>>>/Filter/Standard/Length 128/O(';[\\2}3lVEgVb\(=/T)/P -1340/R 4/StmF/StdCF/StrF/StdCF/U(Z 0~K )/V 4>> endobj 395 0 obj <>/Metadata 11 0 R/PageLayout/OneColumn/Pages 391 0 R/StructTreeRoot 15 0 R/Type/Catalog>> endobj 396 0 obj <>/ExtGState<>/Font<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 397 0 obj <>stream subsp. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. 1979). 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). Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). 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. 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. The labels also give more precise information on mixing and safety precautions. These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. 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. 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. g-a( +6O ,]YE:DumW2ZVQ'h[ ==*`vY7R!vo DKJ@58a+PI}!HB.a0u{'#-&V#_cBG{zBJ)&>Lg>a~7EcB5I]w'Y FQn2 6pa[3,f~66{w[. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). Since it is a nonselective herbicide, it must be carefully applied. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). Cauline leaves are tomentose on the underside and contain spines on the lobe tips. Carduus pycnocephalus, a vigorous annual thistle, arrived in California during the 1930s and has since become a serious weed problem. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. High pH (6.5) also favors growth (Bendall 1975). According to Goeden (1974), C. pycnocephalus serves as an . 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). When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. 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. 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. One drawback is its long persistence in the soil, up to 18 months. macrocephalus (Desf.) Grapevine Green Pruning Residues as a Promising and Sustainable Source of Bioactive Phenolic Compounds. 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 reproduces only by seed. 1979). 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. 2019 Gary McDonald:!2008 Zoya Akulova:!2017 Gary McDonald:!2016 Ken Lunders:!2017 James Bailey:!2019 Cynthia Powell:!2017 Cynthia Powell:!2019 James Bailey:!2019 Julie Kierstead Nelson:!2019 Julie Kierstead Nelson:!2004 Carol W. Witham:! Carduus pycnocephalus is present on both the Ring Mountain and Jepson Prairie preserves in California, with Ring Mountain having the most significant infestation. 1982). . Encyclopedia of Puget Sound is published by the Puget Sound Institute at the UW Tacoma Center for Urban Waters. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). GRAZING, Grazing by sheep, goats, and horses can be effective in control- ling thistles, but cattle are of little value (Parsons 1973).

Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. 8 0 obj It has been introduced, presumably accidentally, to the USA, Australia, New Zealand and some other countries in Europe, Asia, Africa and South America. Munz, P. A. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). 1979). 1979). On this Wikipedia the language links are at the top of the page across from the article title. 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. Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. Please enable it to take advantage of the complete set of features! 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. This site needs JavaScript to work properly. Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent. 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 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. 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. This has proven most effective during the spring and early summer. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. Spraying oil on thistle will be effective only if entire plants are coated. Marengo A, Cagliero C, Sgorbini B, Anderson JL, Emaus MN, Bicchi C, Bertea CM, Rubiolo P. Plant Methods. A common name search of Northwestern Sedge matches 'Northwestern Sedge' and 'Northwestern Showy Sedge'. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought.

GC/MS analysis revealed the presence of nineteen components . pycnocephalus) and the plants in question, Gaskin et al. Serv., U.S.D.A. The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California. 1980). Global Range: Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. Phytochemical analysis of non-volatile fraction of Artemisia caerulescens subsp. [7] It favors grasslands, woodlands, and chaparral vegetation types, but is especially prevalent in oak woodlands in and around the Central Valley. Drought favors a rapid increase in the thistle population. Since it is a nonselective herbicide, it must be carefully applied. "Larvae thought to be Ceutorhynchus trimaculatus 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. 1974. albidus - C. p .

In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. sharing sensitive information, make sure youre on a federal Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). cinereus - C. p . Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle,[1] is a species of thistle. 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).

It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). subsp. The primary threat of this weed is its ability to dominate sites throughout California. C. pycnocephalus is a problem on Nature Conservancy property in this state and presents additional problems on grazed pastures. Seeds are also spread when infested pastures are cut and the hay fed to animals on clean areas. Sheep selectively graze the tender thistles and will kill 90-95% of the weeds. Mechanical methods can be effective but must be done before the plant sets seed. 1985. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. Carduus pycnocephalus Name Synonyms Carduus arabicus subsp. [5][8] Check with local, regional, and national regulations directing use. Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. C. pycnocephalus has been rapidly spreading on rangelands previously dominated by alien annual grasses (Evans et al. Site by, Weed biological control agents approved for California, Taking to the air to locate, prioritize and treat effectively, Tackling invasive plants on California Sept. of Fish & Game lands, Lessons from the front: Taking stock to avoid surprises, California Exotic Pest Plant Council draft list exotic plants of greatest concern October 1993. 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). Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years). 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. The following is a representative barcode sequence, the centroid of all available sequences for this species. 1981). Marengo A, Maciel LS, Cagliero C, Rubiolo P, Herodes K. Plants (Basel). The site is secure. 1981). 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. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Additionally, the root must be severed at least 4 inches (10cm) below the ground to prevent the plant from regenerating. Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. 1979). Two fungi have been evaluated as agents on Italian thistle. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. 1981). 2019 Mar 9;15:23. doi: 10.1186/s13007-019-0408-x. Slashing is more effective than mowing as it destroys the aerial part of the plant more thoroughly (Parsons 1973). 2,4-D can be used in combination with biological control measures to control Carduus. This is partly due to its germination requirements and timing. Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. It persists in the soil for 1-4 weeks. 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 is partly due to its germination requirements and timing. 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. Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. ]KPTjcqD(fIV'.u;!W=:=4MC3AH}t[L72lHA^x`v]X[NC_;p ]&` 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 Weed class: A 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. They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). [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). 393 0 obj <> endobj C. pycnocephalus can germinate at a variety of soil depths. Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. were analyzed and characterized by HPLC-PDA-MS/MS and PCR-RFLP of the nrDNA internal transcribed spacer (ITS). Near streams or lakes particular cautions should be taken when using herbicides. J Chromatogr B Analyt Technol Biomed Life Sci. However, this weed does displace more desirable forage or cover plants. 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. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. [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. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. The effects of prescribed fire on C. pycnocephalus also need investigation. The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. Is this Weed Toxic? Common names Italian plumeless thistle in . Ex. Olympia, WA 98504-2560. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. 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. Epub 2015 Sep 1. Yes, I would like to receive emails from California Invasive Plant Council. The primary threat of this weed is its ability to dominate sites throughout California. Leaves green and nearly hairless above and have cobwebby hairs below.

Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. The seeds germinate at a wide variety of constant and alternating temperatures. Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. 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. 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. 1979). government site. 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. Selective weed oils: There are several petroleum oils used for weed control. 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. University of California Press, Berkeley. It crowds out more desirable forage, as well as native plants, and excludes livestock grazing where infestations are dense. C. pycnocephalus can germinate at a variety of soil depths. Epub 2022 Jan 27. 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. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). 3)uowiF#o (:(#;C 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.
