Biological control of blueweed
Blueweed, Echium vulgare, is a biennial plant native to Europe and Asia that has become a problematic weed in pasture and rangelands of North America where it is classed as noxious. Biological control can be used to help manage the weed. CABI has been tasked with identifying and studying specialist natural enemies from Europe and Asia that can be potentially introduced into North America as biological control agents.
