Bidens pilosa, also known as blackjack, cobbler’s peg, and Spanish needle, among others, is a noxious weed in Africa, North America, Asia, and other parts of the world. In a study published in Allelopathy Journal, researchers tested the natural herbicidal properties of three North American shrubs in genus Baccharis (B. dentata, B. uncinella, and B. anomala) against B. pilosa, as well as their effect on lettuce (Lactuca sativa).
The researchers concluded that B. uncinella was the most effective of the three Baccharis species in terms of potential as a natural herbicide.
