Probleme bei der Unkrautbekämpfung in einem Gebiet mit hohen Abundanzen von Ambrosia artemisiifolia und Möglichkeiten der Reduzierung der Beifuß- Ambrosie in dieser Region

A distribution area of common ragweed (Ambrosia artemisiifolia) is situated in the south of Brandenburg. The weed species appears in arable fields and at roadsides. In some fields herbicide application is required due to the high frequency of weed plants. Efficient herbicides are available in maize but in some crops like legumes and sunflowers the listed herbicides are not sufficiently efficient. Especially in organic farming, at boundary areas and at uncultivated fields solutions for control of common ragweed are still missing.
