Free Amino Acids and Biogenic Amines Profiling and Variation in Wild and Sub-Endemic Cardueae Species from Sardinia and Corse. Marticorena, C. & M. Quezada. Caffeoylquinic acids; Carduus spp. This usually forces a massive germination of thistles that can be destroyed during cultivation (Wheatley and Collett 1981). It persists in the soil for 1-4 weeks. Spraying oil on thistle will be effective only if entire plants are coated. 1979). The essential oil of the air dried aerial parts of Carduus pycnocephalus L. F. Asteraceae was prepared by hydrodistillation. 1959. 2,4-D is available in ester, amine, emulsifiable acid, and low volatile ester formulations. 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). pycnocephalus NATURALIZED Habit: Annual. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Marengo A, Maciel LS, Cagliero C, Rubiolo P, Herodes K. Plants (Basel). Spraying should be done on calm days with dry plants (dew or rain will dilute the herbicide, reducing its effectiveness). Seed dispersal by water and on animals and machinery is less important (Parsons 1973). Without management it cannot be eliminated and may completely carpet the site. BIOLOGICAL CONTROL. High pH (6.5) also favors growth (Bendall 1975). 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. 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. We won't sell or give away your email address. These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. 1971, Baloch and Kahn 1973, Goeden 1974). It is native to: the Mediterranean region in southern Europe, North Africa, and Western Asia; East Europe and the Caucasus; and the Indian Subcontinent. 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. (415) 435-6465. High pH (6.5) also favors growth (Bendall 1975). The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. 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. subsp. 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. Observation: Carduus pycnocephalus L.

Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Sheep selectively graze the tender thistles and will kill 90-95% of the weeds. 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. 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). 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. A great deal of research has been conducted on Carduus species throughout the world, but much more needs to be done on Carduus pycnocephalus. With the right combination of control measures, it should be possible to eliminate C. pycnocephalus from selected areas. 1981). [8][12][13], Grazing by sheep or goats (not cattle) in Australia has showed promise as well.[14]. C. pycnocephalus apparently arrived in California during the 1930s (Goeden 1974). 1998). endstream endobj startxref A significant amount of seed can be produced even if thistles are constantly mowed at 8 cm (Tasmanian Department of Agriculture 1977). FOIA CRUPY ). We suggest you upgrade to a modern browser. Former preserve manager Greg Wolley (1986) has used both hand pulling and cutting to destroy the plants at Ring Mountain Preserve, CA. Near streams or lakes particular cautions should be taken when using herbicides. 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. 2,4-D does not affect grasses. Berkeley, California: The Calflora . The distance that seeds can be spread by wind is not known, but it is at least several hundred meters. other members of the genus Carduus such as C. pycnocephalus have been reported to have potent antiinflammatory activity (Conforti et al., 2009). Sheep selectively graze the tender thistles and will kill 90-95% of the weeds. 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 .

In many of the countries where it has become naturalized it is . They are left ungrazed until the pasture has reached a height of 10-15 cm (about 6 to 10 weeks). Only three insect species appear to hold promise as biological control agents in California (Goeden 1974). 1985. Picloram (Tordon): Dr. Jim McHenry (1985) of the University of California, Davis, recommends picloram to control C. pycnocephalus on Nature Conservancy lands. 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 is the profile for the plant - Carduus pycnocephalus subsp. 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). Epub 2022 Jan 27. 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 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).

Only 2-3 weeks should be required for control. It persists in the soil for 1-4 weeks. It is foliar absorbed and trans- located, making it effective in destroying the roots. Application should be at the rate of 1-1.5 lbs/100 gallons of water with 1 quart of surfactant/100 gallons. It crowds out more desirable forage, as well as native plants, and excludes livestock grazing where infestations are dense. Certorhynchus trimaculatus occurs in Europe and northern Africa (Bolt et al. pycnocephalus Carduus tenuiflorus var. Element Stewardship Abstract; Don Pitcher, Mary J. Russo (revision), 1986. 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. The herbicidal use of oils depends on their chemical and physical properties. [8][9] Its tendency to grow under the canopy of oaks increases the risk of wildfire damage to the trees, as fire can more easily spread to the canopy. 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. Leaves are pinnately lobed into spiny-lobed segments, with the terminal spine being most prominent.
