In the largest COST Action to date, 34 EU countries have banned together to find
a solution to stop Ragweed's spread on the continent. This invasive weed from
North America, now one of the most common air-borne allergens in the EU, causes
half of all asthma attacks in its regions, and costs the EU economy an estimated
€4.5B a year. CABI will join a consortium of over 120 biologists,
ecologists, economists, and medical
experts to explore sustainable solutions. Top on the agenda, biological control,
or using ragweed’s natural enemies to help stop its spread.
