Carduus pycnocephalus was one of the first weeds selected for biological control study by the USDA (Schroeder 1980). Biological control techniques for Carduus species have been extensively studied. The necessity for constant monitoring is all the more important given this weed's potentially long seed dormancy period (to 8 years). 2019 May;161:21-27. doi: 10.1016/j.phytochem.2019.02.005. 1981). 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. It prefers soils of high fertility, and its seedlings establish best on bare or disturbed sites (Wheatley 1971, Parsons 1973). 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. SEED DISPERSAL. The search for its natural enemies has included Italy, Greece, Iran, and Pakistan, as well as southern California (Baloch et al. Most contact oils evaporate slowly and owe their plant toxicity to their high content of aromatic compounds. Munz, P. A. Jordon-Thaden and Louda (2003) and Barros et al. High pH (6.5) also favors growth (Bendall 1975). pycnocephalus (L.) DC., 1838 Homonyms Carduus pycnocephalus L. Carduus pycnocephalus Spreng.

Free Amino Acids and Biogenic Amines Profiling and Variation in Wild and Sub-Endemic Cardueae Species from Sardinia and Corse. This is partly due to its germination requirements and timing. 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. An official website of the United States government. Ants may also play a role in dispersing the seeds (Uphof 1942). Carduus pycnocephalus, a member of the Thistle tribe of the Composite family, is an erect winter annual herb 3-18 dm tall. 42: 1157. 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). The areas are then heavily grazed with sheep at more than twice the normal stocking rate.

S. Calif. 11086. Sign up to receive information about Cal-IPC's upcoming events and project updates. subsp. Similarly, plants which are cut close to flowering time can produce seed on the cut portion. The growth of C. pycnocephalus is favored more by the addition of nitrogen than by phosphorus or potassium. Cal. Italian thistle invades pastures and rangeland. The use of herbicides to control C. pycnocephalus may not be appropriate on natural areas such as Nature Conservancy preserves. 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. 1979).
