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. Larvae of Rhinocyllus conicus feed within the flowerheads of C. pycnocephalus, mining the receptacle and destroying the developing achenes (Goeden 1974, 1978). GERMINATION AND GROWTH. were analyzed and characterized by HPLC-PDA-MS/MS and PCR-RFLP of the nrDNA internal transcribed spacer (ITS). 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. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Marengo A, Maciel LS, Cagliero C, Rubiolo P, Herodes K. Plants (Basel).

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. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. 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). The seeds germinate at a wide variety of constant and alternating temperatures. The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. An official website of the United States government. 1981). No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. endstream endobj startxref [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). 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. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. It is foliar absorbed and trans- located, making it effective in destroying the roots. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. Global Range: Carduus pycnocephalus originated in western and southern Europe but today is widespread throughout temperate parts of the world. 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). 1980). Drought favors a rapid increase in the thistle population. 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. High pH (6.5) also favors growth (Bendall 1975). subsp. Vyhledejte jednodue svj distel obrzek mezi miliony krsnch fotografi, snmk a vektor ve vysok kvalit.

After 48 h of incubation the most antiproliferative plant extract was Cynara cardunculus ssp. Thistles will invade basalt soils earlier than granite soils, and granite soils before sedimentary soils (Wheatley and Collett 1981). They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). The primary threat of this weed is its ability to dominate sites throughout California. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. Munz, P. A. Keywords: Munz, P. A. The seeds start to germinate in the fall with the first effective rain. 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. 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 Circium. Although other thistle species present greater problems on these preserves, C. pycnocephalus control has been included as an adjunct to other control efforts. Marticorena, C. & M. Quezada. 2023 Jan 10;12(2):319. doi: 10.3390/plants12020319. Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). & D. D. Keck.

Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). Cauline leaves are tomentose on the underside and contain spines on the lobe tips. L.Photo by G. Piper. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. This period also corresponds to the germination and vegetative growth periods of C. pycnocephalus (Oliveri 1984). Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California.

Observation: Carduus pycnocephalus L. (florenza artale May 1, 2022) World flora (Species of the World flora) May 1, 2022 The labels also give more precise information on mixing and safety precautions. Its spiny leaves, stems, and phyllaries prevent animals from grazing on it and nearby forage. Carduus pycnocephalus, with common names including Italian thistle, Italian plumeless thistle, and Plymouth thistle, is a species of thistle. A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. 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.

Clipboard, Search History, and several other advanced features are temporarily unavailable. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). 1979). 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). These thistles can be cultivated or manually removed when small. It survives best at low temperatures with short photoperiods (Kok 1979). Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. 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. 1979). Grazing by sheep, goats, and horses can be effective in controlling thistles, but cattle are of little value (Parsons 1973). Olympia WA 98504, P.O Box 42560 1981). Hand pulling, cultivation, and grazing are all effective control measures. Phenolic Composition of Inflorescences of Carduus nutans L. Intra-specific variation in the little-known Mediterranean plant Ptilostemon casabonae (L.) Greuter analysed through phytochemical and biomolecular markers. In field situations, the added hardship of intra- and interspecific competition may cause a greater effect on thistle populations. C. pycnocephalus seeds exhibit polymorphism, with brown seeds that have less mucilage and germinate at lower temperatures than silver seeds. Careers. High pH (6.5) also favors growth (Bendall 1975). Near streams or lakes particular cautions should be taken when using herbicides. It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) /app/up/entry/73/th/22000.jpg:!0000 0000 0108 1272:!/app/up/mg/44/th/13398.jpg:!/app/up/entry/29/th/8868.jpg:!/app/up/cbo/248/th/74532.jpg:!/app/up/mg/280/th/mg84205-2.jpg:!/app/up/mg/185/th/mg55602-2.jpg:!/app/up/io/39/th/io11908-0.jpg:!/app/up/gp/78/th/15673.jpg:!/app/up/entry/90/th/27010.jpg:!0000 0000 1104 0321:! /Filter /LZWDecode [5][8] Check with local, regional, and national regulations directing use. Carduus pycnocephalus is present on both the Ring Mountain and Jepson Prairie preserves in California, with Ring Mountain having the most significant infestation. [5][10], Biological control agents have limited success with Carduus pycnocephalus. The areas are then heavily grazed with sheep at more than twice the normal stocking rate. Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. Please enable it to take advantage of the complete set of features! intermedius - C. p . The mucilage is abundant and adhesive enough to aid in seed dispersal (Evans et al. Carduus pycnocephalus Common Names: Italian thistle Evaluated on: 5/22/04 List committee review date: 08/07/2005 Re-evaluation date: Evaluator (s) John J. Knapp/ Invasive Plant Program Manager Catalina Island Conservancy P.O. C. pycnocephalus can germinate at a variety of soil depths. 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 reproductive host. Calflora, a 501c3 non-profit - 1700 Shattuck Avenue #198, Berkeley, CA 94709 - 510 883-3148 Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. %%EOF 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). It displaces desirable forage or cover plants, but more commonly colonizes disturbed habitats where interspecific competition is less intense (Goeden 1974). Carduus pycnocephalus is a thistle that is native to the Mediterranean region and some other countries further north or east. Life cycle . synonym auct. This is the profile for the plant - Carduus pycnocephalus subsp. Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). 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. 1998). Several management techniques appear promising, and integrated control operations involving a combina- tion of practices need investigation. Olympia, WA 98504-2560. When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. BIOLOGICAL CONTROL. Psylliodes chalcomera was a fairly consistent associate of C. pycnocephalus in its vegetative and early reproductive stages throughout central and southern Italy.

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). 1979). [2] 2023. It is found in disturbed areas, often with basaltic soils, fertile soils, or soils with a relatively high pH (> 6.5).[5][7]. 11681. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). Then sheep will graze the thistle along with the grass. Serv., U.S.D.A. Selective weed oils: There are several petroleum oils used for weed control. Note: This information is based on publications available through Tropicos and may not represent the entire distribution. Plants grow up to 20 dm, are often slightly woolly, and narrowly winged along stems and spined. macrocephalus (Desf.) The herbicidal use of oils depends on their chemical and physical properties. 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). 2,4-D has been applied to C. pycnocephalus with limited success (Taylor 1977). 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 ( Control of C. pycnocephalus requires active management once it becomes established in an area. 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. HHS Vulnerability Disclosure, Help Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. (eds. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). 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). Epub 2022 Jan 27. CRUPY ). 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). C. pycnocephalus can germinate at a variety of soil depths. [web application]. [11] Puccinia cardui-pycnocephali is a species of rust (fungus) apparently exclusive to Carduus pycnocephalus. Only 2-3 weeks should be required for control. Mapping weeds and rare plants to inform management and conservation in the Zaca and Jesusita fires. The essential oil of the air dried aerial parts of Carduus pycnocephalus L. F. Asteraceae was prepared by hydrodistillation. 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. (2005) have reported the presence This has proven most effective during the spring and early summer. Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. 1978). Italian Plumeless-thistle - Italian plumeless thistle. One drawback is its long persistence in the soil, up to 18 months. With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas. 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, 1979). Gayana, Bot. 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. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Home | Contact | UW Privacy | UW Terms of Use.

Federal government websites often end in .gov or .mil. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. 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. Bookshelf 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. Naturalized as a weed. A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. 1979). 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. 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. Utilizing double quotes for exact terms can narrow your search results. 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). Chemical control can be achieved with a variety of products including: Clopyralid, glyphosate, Diquat, Picloram, and 2, 4-D ester. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. This has proven most effective during the spring and early summer. 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. Statistical analyses, on both chemical and biomolecular results, revealed that individuals clustered according to their taxonomic classification. A Certified Pest Control Applicator should be hired for large jobs or those requiring nonselective herbicides. Flowers are purple.
