Bio-herbicidal potential of extracts from allelopathic plants against the emergence of multi-species weed seed bank in Ghana

Background: Growing public concerns about the health and environmental hazards associated with synthetic herbicides have necessitated the pursuit of sustainable weed management alternatives. Allelopathic plant extracts present a potential solution for environmentally friendly weed control. However, little is known about the bioherbicidal potential of allelopathic plant species native to Ghana. Objective: This study screened aqueous and ethanol extracts from allelopathic plants in Ghana, to examine their potential as bio-herbicides for sustainable weed management, and also identified the allelocompounds present.
