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. 2,4-D can be used in combination with biological control measures to control Carduus. (Hawkes et al. [11] Puccinia cardui-pycnocephali is a species of rust (fungus) apparently exclusive to Carduus pycnocephalus. 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. When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. 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. Marengo A, Maciel LS, Cagliero C, Rubiolo P, Herodes K. Plants (Basel). This weevil has been studied in depth as a candidate biological control agent by USDA entomologists and may be usefully employed against C. pycnocephalus and other Carduus species in North America in the near future" (Goeden 1974). Insects that tested host-specific by the California Dept. A winter annual, Carduus pycnocephalus stems range from 8 inches (20cm) to 6.6 feet (2.0m), and are glabrous to slightly wooly. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Bookshelf %%EOF Brahmi-Chendouh N, Piccolella S, Gravina C, Fiorentino M, Formato M, Kheyar N, Pacifico S. Foods. It is most effective when applied in February or March at 1/8 to 1/16 lb acid equivalent per acre. C. pycnocephalus can germinate at a variety of soil depths. 1. 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 .

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. 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). GRAZING, Grazing by sheep, goats, and horses can be effective in control- ling thistles, but cattle are of little value (Parsons 1973). The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. SEED DISPERSAL. 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). It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) 3)uowiF#o (:(#;C 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). Continuous grazing significantly reduces thistle numbers but is not as effective as the use of an autumn break (Bendall 1973). Ants may also play a role in dispersing the seeds (Uphof 1942). 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. 2023. 437 0 obj <>/Encrypt 394 0 R/Filter/FlateDecode/ID[<6077C6EA8B98D0438538133787DC7747><7352E31CF2E5D44D8E07E3D1DB06B7BC>]/Index[393 71]/Info 392 0 R/Length 171/Prev 295012/Root 395 0 R/Size 464/Type/XRef/W[1 3 1]>>stream Grazing by sheep, goats, and horses can be effective in controlling thistles, but cattle are of little value (Parsons 1973).

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. b. Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. This weevil has been studied in depth as a candidate biological control agent by USDA entomologists and may be usefully employed against C. pycnocephalus and other CARDUUS species in North America in the near future" (Goeden 1974). A common name search of Northwestern Sedge matches 'Northwestern Sedge' and 'Northwestern Showy Sedge'. Tropicos does not categorize distributions as native or non-native. The areas are then heavily grazed with sheep at more than twice the normal stocking rate.

The chemical is noncorrosive and is generally considered nonharmful to wildlife. It is foliar absorbed and trans- located, making it effective in destroying the roots. J Chromatogr B Analyt Technol Biomed Life Sci. 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. Grapevine Green Pruning Residues as a Promising and Sustainable Source of Bioactive Phenolic Compounds. Biological control techniques for Carduus species have been extensively studied. 1978). 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. Carduus speciesUnlike , Cirsium species have feathery, plumose pappus hairs (Douglas et al. 1982). 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. Mechanical methods can be effective but must be done before the plant sets seed. Mowing or slashing is not always reliable because the plant can regrow from the base and produce seeds very quickly. CRUPY ). This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). Ethiopian traditional medi- . BIOLOGICAL CONTROL. 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). 393 0 obj <> endobj Development of an innovative and sustainable one-step method for rapid plant DNA isolation for targeted PCR using magnetic ionic liquids. The multiple stems are winged with spines. Grubbing hoes must cut the plants 2 to 4 inches below ground level to prevent resprouting from dormant axillary buds. No after-ripening is required, and seeds can germinate either rapidly or after a long dormancy period. 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. University of Turin Instituional Repository AperTO. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought. It is found in disturbed areas, often with basaltic soils, fertile soils, or soils with a relatively high pH (> 6.5).[5][7]. The seeds germinate at a wide variety of constant and alternating temperatures. 2007. Clipboard, Search History, and several other advanced features are temporarily unavailable. Its inability to reproduce vegetatively makes control easier, but constant monitoring will be necessary due to its potentially long seed dormancy (to 8 years).

Utilizing double quotes for exact terms can narrow your search results. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). (415) 435-6465. Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. 1978). macrocephalus (Desf.) Native to: Northern Africa, Asia and Western and Southern Europe Randall, and M. Hoshovsky. Control of C. pycnocephalus requires active management once it becomes established in an area. The areas are then heavily grazed with sheep at more than twice the normal stocking rate. Western and central Europe, Mediterranean, Macaronesia, Caucasus, Western Asia, Himalayas. 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). 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. Marengo A, Maxia A, Sanna C, Mandrone M, Bertea CM, Bicchi C, Sgorbini B, Cagliero C, Rubiolo P. Phytochemistry. Management Requirements: With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas. Several management techniques appear promising, and integrated control operations involving a combination of practices need investigation. hC:2r)#OH93 0@cxC1!8,j`Ma# 2pXC3,F7h@6KA #;KqAS$ alA0@7-: 1*KP;Kj/Q2cH#65SLK1IH8-:DL`@U`AWVeV eCollection 2019.

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. C. pycnocephalus has been rapidly spreading on rangelands previ- ously dominated by alien annual grasses (Evans et al. Cone sprayers produce greater atomization of the chemicals and increase the chance of drift into unwanted areas. Observation: Carduus pycnocephalus L.

Prior to using any herbicide, check with the County Agricultural Commissioner to determine which chemicals are legal to use in a given situation. 1979). Carduus species (Compositae) are widely distributed in the Mediterranean area, and traditionally used for both food and medicinal purposes. 1985. Monitoring is needed to determine the effectiveness of any C. pycnocephalus control measures. . Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent. 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). Bendall (1974) found that 85% of Carduus pycnocephalus seeds produce germination inhibitors, but they are readily leached. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. Ready-to-Use Nutraceutical Formulations from Edible and Waste Organs of Algerian Artichokes. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Naturalized as a weed. Serv., U.S.D.A. It is widely distributed in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas across much of California. 9PA$R-T8K3!"m8!NFC 8Lfyp4Mk^.nau]boY@f1!($4F &h4.L1=T]eC[,`9ZCxh2 It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 1974. 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.
