Bioherbicidal activity and putative mode of action of Dittrichia graveolens against Amaranthus palmeri and A. retroflexus
The aqueous extract of D. graveolens exhibited concentration-dependent allelopathic effects on A. palmeri and A. retroflexus, with A. retroflexus showing greater sensitivity overall and A. retroflexus being more sensitive than A. palmeri on germination.
