Das EU Projekt HALT Ambrosia – Fragen und Antworten

Abstract

The aim of the project is to contribute to the reduction of the prevalence of common ragweed (Ambrosia artemisiifolia L.) in European countries in order to reduce the burden on public health, agriculture and biodiversity. This will consist of developing strategy elements for the reduction of common ragweed and its pollen in countries where the species is already established, e.g., Hungary, Slovenia, parts of Austria, and Southeastern Europe and for the prevention of further import and spread in countries not yet heavily infested, such as Germany, the Netherlands and Northern European countries. Laboratory and field experiments covered the germination biology and seed bank behaviour and the impacts of chemical and non-chemical control strategies on common ragweed. Trials on integrated control strategies like increased competition on common ragweed were conducted, too. Desk-top studies on biological control and investigations of the impact of common ragweed on the biodiversity were carried out by associated project partners. Based on these results recommendations for successful control of common ragweed in rural and non-rural areas have been developed.
