Summary The recent invasion by (common ragweed) has, like no other plant, raised awareness invasive plants Europe. main concerns regarding this plant are that it produces a large amount highly allergenic pollen causes high rates sensitisation among humans, but also A. is increasingly becoming major weed agriculture. Recently, chemical and mechanical methods have been developed partially implemented Europe, sustainable strategies to mitigate its spread into areas not yet invaded reduce abundance badly infested lacking. One management tool, Europe successfully applied Australia, control. Almost all natural enemies colonised polyphagous cause little damage, rendering them unsuitable system approach. Two fungal pathogens reported adversely impact introduced range, their biology makes mass production application as mycoherbicide. In native range on hand, number herbivores associated with very narrow host seed production, stage most sensitive long‐term population winter annual. We discuss propose prioritisation these candidates classical or inundative approach against capitalising past experiences North America, Asia Australia.
