Ambrosia artemisiifolia L. (common ragweed) is a weed original from North America from where it spread in Europe around 1870. In our country, it first appeared in the Banat Region, at the beginning of the 20th century. As a result of research carried out between 2002 and 2005, the species was identified in all 27 control points in the plain area of the Banat, with numerous and wide populations (2,9 - 126,1 weeds/m2) located on non-cultivated agricultural lands or on lane lands. On cultivated lands, common ragweed has been only sporadically signalled (0,3 - 4,1 weeds/m2), in 5 control points, only in tillage spring crops (sunflower, maize, vegetables). If from an agricultural point of view Ambrosia artemisiifolia L. does not represent, at least for the moment, a threat, if we take into account the serious health issues (it's pollen causes hay fever in humans) we need to keep it under control.
