Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. Statistical analyses, on both chemical and biomolecular results, revealed that individuals clustered according to their taxonomic classification. Anonymous. 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.

Bookshelf Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California. 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. 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. doi: 10.1002/cbdv.202100827. 1980). 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. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. Italian thistle is a spiny annual or sometimes biennial that can grow 6 to 8 feet in height. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). Carduus species can be distinguished from native and introduced Cirsium species by their simple pappus hairs. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). These thistles can be cultivated or manually removed when small.

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. 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). They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). Hand pulling, cultivation, and grazing are all effective control measures. Clipboard, Search History, and several other advanced features are temporarily unavailable. Repeated greenhouse inoculations of the rust on growing rosettes signif- icantly reduced the growth of C. pycnocephalus but not the number of florets (Oliveri 1984). 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.

The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 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]. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. 1979).

Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Chemicals such as Picloram and 2,4-D may be of some use in controlling the weed, but an integrated management program involving a combination of techniques will prove most effective. The seeds start to germinate in the fall with the first effective rain. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 42: 1157. 2019 May;161:21-27. doi: 10.1016/j.phytochem.2019.02.005. 1971, Baloch and Kahn 1973, Goeden 1974). 1. 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 medicinal uses

1980). Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. 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. Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy.

Deferring autumn grazing of sheep has been effective in reducing stand density because the thistles grow etiolated and less spiny when competing with ungrazed grasses. Species of flowering plant in the daisy family Asteraceae. 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 . cinereus - C. p . 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. 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. Utilizing double quotes for exact terms can narrow your search results. 2,4-D can be used in combination with biological control measures to control Carduus. 1979). 1979). 1979). Stem: 2--20 dm, glabrous or slightly woolly, narrowly spiny-winged. [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. 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. Two fungi have been evaluated as agents on Italian thistle. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. (415) 435-6465. Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent. Encyclopedia of Puget Sound is published by the Puget Sound Institute at the UW Tacoma Center for Urban Waters. The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. Keywords: Fl. In many of the countries where it has become naturalized it is . Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. The seeds germinate at a wide variety of constant and alternating temperatures. Stewardship Overview: Carduus pycnocephalus, a vigorous annual thistle, arrived in California during the 1930s and has since become a serious weed problem. Seed germination rate in Carduus pycnocephalus is very high, ranging between 83-96%. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. It persists in the soil for 1-4 weeks. Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. Ants may also play a role in dispersing the seeds (Uphof 1942). [5][8] Check with local, regional, and national regulations directing use. 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. 1981). 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. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). C. pycnocephalus can germinate at a variety of soil depths. marmoratus - C. p . cardunculus on C32 and .

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. arduus pycnocephalus L. Photo by A. Brousseau. 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. Italian thistle can facilitate fire spread and frequency by providing fuels in some habitats and creates monocultures that reduce native seedling recruitment and survival. Flowers are purple. Syst. 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. Contact: Larry Serpa, Area Manager. It is a host species for the introduced weevil, Rhinocilus conicus, which also attacks native thistles. Fl. 2019 Mar 9;15:23. doi: 10.1186/s13007-019-0408-x. 1959. 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. Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. J Chromatogr B Analyt Technol Biomed Life Sci. 2023. 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. Flower heads typically occur in clusters of 2-5. Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy. Grazing by sheep, goats, and horses can be effective in controlling thistles, but cattle are of little value (Parsons 1973). Drought favors a rapid increase in the thistle population. Carduus pycnocephalus is an annual herb that is not native to California. . It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. Carduus pycnocephalus auct. 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. 1979). Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. Please click here to see a county level distribution map of Italian thistle in Washington. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. After 48 h of incubation the most antiproliferative plant extract was Cynara cardunculus ssp. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. 2007.

Mechanical methods can be effective but must be done before the plant sets seed. Life cycle . [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. GC/MS analysis revealed the presence of nineteen components . 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). 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). Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. In high fertility situations, using a roller to compact the soil is recommended during seedbed preparation (but not during seed sowing). The herbicidal use of oils depends on their chemical and physical properties. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. 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. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. Please see WAC 16-752 for more information on the quarantine list. The primary threat of this weed is its ability to dominate sites throughout California. Missouri Bot. Selective weed oils: There are several petroleum oils used for weed control. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. GERMINATION AND GROWTH. Our website has detected that you are using an outdated insecure browser that will prevent you from using the site. 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 distance that seeds can be spread by wind is not known, but it is at least several hundred meters. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). Without management it cannot be eliminated and may completely carpet the site. 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. 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. It survives best at low temperatures with short photoperiods (Kok 1979). Presentations are linked where available. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). Biological control techniques for Carduus species have been extensively studied. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. Common names Italian plumeless thistle in . 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. The fungal rust Puccinia Carduii-pycnocephali Sydow, is known to occur only on the genus Carduus (Batra et al. Nyman, Carduus pycnocephalus L., Carduus cephalanthus Viv.) Cal. Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. 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). Ants may also play a role in dispersing the seeds (Uphof 1942). 1979). 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. PMC %PDF-1.6 % [8] Other rust species have been found on Italian thistle as well. Similarly, plants which are cut close to flowering time can produce seed on the cut portion.

HHS Vulnerability Disclosure, Help 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). Management Requirements: With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Gayana, Bot. 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). 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. [3], Flower heads are 2-5 per cluster, densely matted with cobwebby hairs at the base of the phyllaries and spiny towards the tips. University of California Press, Berkeley. Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). 1982). Though some Carduus species are known to accumulate nitrates in toxic quantities, C. pycnocephalus has apparently not been incriminated as a toxic weed (Goeden 1974). 2,4-D does not affect grasses. 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.

Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. CRUPY ). 1972) and in 1973 to control C. pycnocephalus in southern California (Goeden and Ricker 1978). 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. 3152 Paradise Drive, Room 101, Tiburon, CA 94920. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). government site. 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 search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Only 2-3 weeks should be required for control. 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 . 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). Slenderflower thistle, Carduus tenuiflorus, Washington State Noxious Weed Control Board. 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. High pH (6.5) also favors growth (Bendall 1975). .4-.6 in (1-1.4cm) long, and the fruits are brown to gold, with a bristly, minutely barbed pappus. Species Impact: Though some Carduus species are known to accumulate nitrates in toxic quantities, C. pycnocephalus has apparently not been incriminated as a toxic weed (Goeden 1974). >> The hydroalcoholic extracts of four wild edible Carduus species collected in Sardinia (Carduus argyroa Biv., Carduus nutans subsp. Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. Statistical analyses, on both chemical and biomolecular results, revealed that individuals clustered according to their taxonomic classification. Anonymous. 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.

Bookshelf Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. The ITS region was sequenced in parallel, and a PCR-RFLP method was applied with three selective restriction enzymes. Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California. 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. 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. doi: 10.1002/cbdv.202100827. 1980). 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. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). It occurs in a variety of disturbed habitats and germinates rapidly and in large numbers. Bracts at the base of flowerheads are stiff and upright with forward pointing hairs. Italian thistle is a spiny annual or sometimes biennial that can grow 6 to 8 feet in height. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). Carduus species can be distinguished from native and introduced Cirsium species by their simple pappus hairs. Seed dispersal by water and on animals and machinery is less important (Parsons 1973). These thistles can be cultivated or manually removed when small. Introduced in Sri Lanka, Ethiopia, USA, Uruguay, Australia, New Zealand, PP1 - Efficacy Evaluation of Plant Protection Products, PP3 - Environmental Risk Assessment of Plant Protection Products, PM4 - Production of Healthy Plants for Planting, PM8 - Commodity-specific Phytosanitary Measures, PM9 - National Regulatory Control Systems, Regional Plant Protection Organizations / EU / EAEU, Carduus pycnocephalus ( Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. Serv., U.S.D.A. Observation: Carduus pycnocephalus L. (florenza artale May 1, 2022) World flora (Species of the World flora) May 1, 2022 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. 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. 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). They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). Hand pulling, cultivation, and grazing are all effective control measures. Clipboard, Search History, and several other advanced features are temporarily unavailable. Repeated greenhouse inoculations of the rust on growing rosettes signif- icantly reduced the growth of C. pycnocephalus but not the number of florets (Oliveri 1984). 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. Weed class: A Monitoring is needed to determine the effectiveness of any C. pycnocephalus control measures. 0 Wb p Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). The multiple stems are winged with spines. ; Flavonoids; HPLC-PDA-MS/MS; ITS sequence; PCR-RFLP. Without management it cannot be eliminated and may completely carpet the site. macrocephalus (Desf.) Picloram kills half the test animals (LD50) at 8000 mg/kg body weight and is considered to be of "relatively no hazard." See our postcardfor early detection information about Italian and slenderflower thistle. (Hawkes et al. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). Naturalized as a weed. Contact: Larry Serpa, Area Manager. 463 0 obj <>stream /Length 9 0 R Ants may also play a role in dispersing the seeds (Uphof 1942). C. pycnocephalus seeds are mucilaginous, unlike most other thistles. 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.

The length of time the seeds can survive in the soil is not known but appears to be at least 8 years (Parsons 1973). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. 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]. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. 1979). UFRGS,1-132,2020, Karlsson (2004-03-18 23:00:00) Frteckning ver svenska krlvxter, Monogr. The seeds germinate at a wide variety of constant and alternating temperatures.

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. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. Chemicals such as Picloram and 2,4-D may be of some use in controlling the weed, but an integrated management program involving a combination of techniques will prove most effective. The seeds start to germinate in the fall with the first effective rain. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 42: 1157. 2019 May;161:21-27. doi: 10.1016/j.phytochem.2019.02.005. 1971, Baloch and Kahn 1973, Goeden 1974). 1. Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years).
