Fl. 2,4-D does not affect grasses. 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. Seedlings grow through the winter as rosettes and produce flowering stalks in the late spring before the summer drought.

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. It is a serious pest in Australia, New Zealand, South Africa, Pakistan, Iran, and Europe. Seed dispersal by water and on animals and machinery is less important (Parsons 1973).

High pH (6.5) also favors growth (Bendall 1975). CRUPY ). 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. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973).

Carduus pycnocephalus L, which is related to the Astraceae family, was well-known as a privileged medicinal plant that has innumerable respected biological potency. 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. 3 Carpocoris mediterraneus.jpg 2,150 1,616; 1.79 MB C. bourgeanus-asp-2.jpg 2,448 3,264; 4.28 MB C. pycnocephalus-brcteas-1.jpg 3,121 2,342; 1.79 MB C. pycnocephalus-brcteas-2.jpg 2,048 1,536; 1.19 MB 8600 Rockville Pike 1959. 2,4-D does not affect grasses. 8 0 obj
Carduus pycnocephalus reproduces only by seed. Spraying oil on thistle will be effective only if entire plants are coated. : This plant is also on the Washington State quarantine list. 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). Slenderflower thistle, Carduus tenuiflorus, is similar but it generally has more flowerheads (5-20), than Italian thistle, Carduus pycnocephalus (1-5 flowerheads). Bot.

It was imported into California in 1969 for the biological control of milk thistle (Silybum marianum Gaertn.) 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. 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.

Genus Carduus which belongs to the family Astraceae includes approximately 100 species worldwide ( Chaudhary, 2000) and is widely distributed around the Mediterranean. Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Ants may also play a role in dispersing the seeds (Uphof 1942). Introduction. The herbicidal use of oils depends on their chemical and physical properties. A variety of herbicides have been used on C. pycnocephalus, but they give only temporary control (Wheatley and Collett 1981). C. pycnocephalus can germinate at a variety of soil depths. Because of this concern, their use has been somewhat limited. The areas are then heavily grazed with sheep at more than twice the normal stocking rate. Italian thistle can grow densely, crowding out other vegetation with dense rosette 'colonies' in the winter, thereby preventing establishment of native plants. 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. Cultivation before seed production will eventually eliminate thistles, but only if repeated for several years. The seeds germinate at a wide variety of constant and alternating temperatures. 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. macrocephalus (Desf.) 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. 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. %
Gayana, Bot. 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). Surfactants affect the surface property of the spray by lowering surface tension to increase the herbicide's effectiveness. [2] 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. C. pycnocephalus seeds are mucilaginous, unlike most other thistles. 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. 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). GC/MS analysis revealed the presence of nineteen components . These species are Psylliodes chalsomera, Rhinocyllus conicus, and Ceutorhynchuys trimaculatus. Seeds of C. pycnocephalus exhibit rapid germination (within 2 weeks) at optimum temperatures (Evans et al. 1971, Baloch and Kahn 1973, Goeden 1974). 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. Generally it does poorly on the surface of a bare seedbed, but on the surface of clay soils it shows 70% germination. 2023. 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). According to Goeden (1974), C. pycnocephalus serves as an . 1972) and in 1973 to control C. pycnocephalus in southern California (Goeden and Ricker 1978). When spraying large areas, a horizontal boom (6-8 feet long) made from aluminum tubing will improve herbicide coverage. 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.
