|Abstract||Both weed science and plant invasion science deal with noxious plants. Yet, they have historically developed as two distinct
research areas in Europe, with different target species, approaches and management aims, as well as with diverging institutions
and researchers involved. We argue that the strengths of these two disciplines can be highly complementary in implementing
management strategies and outline how synergies were created in an international, multidisciplinary project to develop efficient
and sustainable management of common ragweed, Ambrosia artemisiifolia. Because this species has severe impacts on human
health and is also a crop weed in large parts of Europe, common ragweed is one of the economically most important plant
invaders in Europe. Our multidisciplinary approach combining expertise from weed science and plant invasion science allowed
us (i) to develop a comprehensive plant demographic model to evaluate and compare management tools, such as optimal cutting
regimes and biological control for different regions and habitat types, and (ii) to assess benefits and risks of biological control.
It further (iii) showed ways to reconcile different stakeholder interests and management objectives (health versus crop yield),
and (iv) led to an economic model to assess invader impact across actors and domains, and effectiveness of control measures.
(v) It also led to design and implement management strategies in collaboration with the various stakeholder groups affected by
noxious weeds, created training opportunities for early stage researchers in the sustainable management of noxious plants, and
actively promoted improved decision making regarding the use of exotic biocontrol agents at the national and European level.
We critically discuss our achievements and limitations, and list and discuss other potential Old World (Afro-Eurasian) target
