Objectives

• Improve knowledge about the biology of common ragweed, and identify those parts of its life cyle that are most sensitive for control
• Understand the history and modes of spread of common ragweed, and actual degree of infestation throughout European countries
• Evaluate the levels of adaptation enabling common ragweed to increase its invasive range
• Optimization of non-chemical control like adaptive cutting regimes and seeding competitors

Expected deliverables

• Recommendations for optimal cutting regimes in habitat types where other measures cannot be applied
• Propose seed mixtures that work well at the regional level in outcompeting ragweed
• Develop a concept for monitoring common ragweed populations in Europe
