Strategies for non-chemical control of invasive allergenic neophyte Ambrosia artemisiifolia L.
Abstract
Common Ragweed (Ambrosia artemisiifolia L.) is a problematic invasive neophyte currently spreading all over Europe. It causes crop yield losses in agriculture and produces enormous amounts of pollen, which causes severe allergies and asthma and implies high medical costs. The pollen can be transported by wind to very long distances. The general purpose of the present project is to improve non-chemical and sustainable methods of control, as an alternative to herbicides. The latter are mainly used in agriculture, but cannot be applied in all cases (for ex. not in sunflower fields). Sometimes herbicides are forbidden out of environmental concern (on the roadsides and near human settlements), or cannot be used because this highly adaptive plant develops resistance to them. In this project, pot and field experiences are planned to test the efficiency of various mowing combinations (varying the height, timing and frequency of cutting) as well as sowing of concurrent vegetation (three standard seed mixtures are tested). The research is done in close collaboration with road maintenance authorities in order to conduct the experiment under realistic conditions. The results will bring knowledge about the biology of the species and measures to be undertaken to avoid further spreading of this problematic species. The significance of the project is clear considering the high medical costs that can be avoided if this species is controlled efficiently.
