Appearance and spreading of common ragweed (Ambrosia artemisiifolia L.) in Bosnia and HerzegovinaBašić, Fejzo (Avtor) Đikić, Mirha (Avtor) Gadžo, Drena (Avtor) common ragweedinvasive weedsBosnia and HerzegovinaIt has been more than seven decades since the first data on the presence of common ragweed (Ambrosia artemisiifolia) in Bosnia and Herzegovina was published. The literature data show that this invasive weed species has spread and became naturalized in a major part of Bosnia and Herzegovina, and has a tendency of further spreading. It is believed that was introduced from the north and spread towards the south. Depending on the weather conditions, common ragweed occurs predominantly during the mid-spring and produces inflorescences from July until the first frost. The common ragweed plants can grow to be over 2 meters high. This species is very adaptive to different environmental conditions, and its fast expansion in the area of Bosnia and Herzegovina was favored by the increase of areas under uncultivated and abandoned land after the war. Since common ragweed is harmful both as a weed species and as an allergenic plant dangerous to human health, it is necessary to take all available measures to prevent its further spread, but also to reduce the number of populations in the areas where it is already established.20172026-01-28 10:22:15Neznano26983UDK: 582.991.1(497.6)ISSN pri članku: 1855-7996DOI: 10.3986/fbg0032COBISS_ID: 43255085slImetniki avtorskih pravic na prispevkih so avtorji
