Russian knapweed is a serious weed of dryland crops in its native range. It has been suggested that Russian knapweed likely established in North America wherever Turkestan alfalfa had been planted due to contamination of the alfalfa seed (Zouhar 2001).
Russian knapweed is a long-lived creeping perennial. It is the most widely distributed knapweed species in North America. It displaces desirable vegetation. Once established, Russian knapweed can form a monoculture and overtake large areas. Resulting infestations can reduce forage and wildlife habitat.
