Dipsacus fullonum

... in Argentina, common teasel is found in some of the most important natural conservation areas, forming dense monocultures which displace desirable species, including the “Otamendi Natural Reserve”, (34o142’ S; 58o532’ W) (Cordo, 2004) and “Costanera Sur Ecological Reserve” (34o36’ S; 58o21’ W). (Daddario et al., 2017)

Dipsacus fullonum L. is a biennial weed that is widely spread in the Pampean region of Argentina. Plants of this species showing leaf mosaic symptoms were collected near sunflower (Helianthus annuus L.) crops infected with Sunflower chlorotic mottle virus (SuCMoV). Symptomatic plants were tested by biological, serological and molecular assays.... Results indicate that D. fullonum mosaic is caused by an isolate of SuCMoV. Thus, this finding has epidemiological relevance as the weed may act as a natural virus reservoir.

- O cardo comum é uma espécie invasora disseminada que foi introduzida na província de Buenos Aires, Argentina, onde altera a composição de espécies de áreas protegidas e pastagens nativas.

Teasel is an invasive weed which negatively impacts infested areas. Teasel can reduce species diversification in natural areas, leading to less available food sources for wildlife. Cut-leaved teasel has been reported to present considerable problems for conservation in natural areas such as the suppression or elimination of native species which alters nutrient and hydrological cycles (Huenneke and Thomson 1994; Solecki 1993; Werner 1977). The taproot can alter soil moisture levels by reducing infiltration and increasing runoff (Lacey et al. 1989). (Bentivegna, 2006)
