Allelopathic Potential of Aqueous Extracts from Fleagrass (Adenosma buchneroides Bonati) against Two Crop and Three Weed Species

This study aimed to assess the phytotoxic potential of fleagrass (Adenosma buchneroides) on weeds and crops. We assessed effects applying aqueous extracts seed germination seedling growth three (Bidens pilosa, Paspalum thunbergia, Bromus japonicus) two crops (Oryza sativa Zea mays). The influence six doses extract was through a Petri dish experiment. qualitatively characterized using widely targeted metabolomics analysis found mainly comprise flavonoids, phenolic acids, alkaloids, polysaccharides, phenylpropanoids, terpenoids, phenolamides, quinones. mean IC50 for crop 168,796, weed 11,454. inhibition effect tested species, from highest lowest, followed order B. japonicus > Pilosa P. thunbergii O. Z. mays. These results indicate remarkable species-specific sensitivity treatment, that are more tolerant than weeds. Elucidation details fleagrass–weed/crop interaction can serve as basis intercropping with in management strategies at controlling
