| Résumé : |
Common ragweed (Ambrosia artemisiifolia L.) was described in Switzerland already in the end of the 19th century. Ragweed remained hidden until changing conditions triggered its spread. The invasion of this neophyte in Switzerland is still in a stage, where an effective low cost control should be feasible. A survey of the Swiss Research station Agroscope Changins-Wädenswil ACW, formerly RAC Changins, showed a clear trend for 2005: Beside a few known foci in arable fields, ragweed grows mainly in private garden sites all over the country. Ragweed follows human activities, and it was observed that its seeds are found in bird grain mixtures. Seeds also enter the regions along the French and Italian borders by agricultural machines and excavated material from building sites. The fact that ragweed endangers public health was one reason to follow more carefully its beginning invasion. The spread of ragweed from private house gardens via compost or via professional gardening as pathways to the fields seems to be very easy. Therefore it was necessary to act rapidly to start an effective campaign in 2005. The information on how to eradicate ragweed went to all municipalities in Switzerland and met increasing interest. This year, the aim was to eradicate ragweed in house gardens, to reduce seed production and to make ragweed known to the population. The campaign will be continued in 2006. |
