This study aims to determine the contents of phenolic compounds from sorghum shoot extracts by fractional extraction in different solvents (ethanol, ethanol-chloroform, ethanol-hexane, ethanol-ethyl acetate, and ethanol-methylene chloride) and to assess their weed control efficacy. Results showed that the highest total amount of phenolic compounds was extracted using the solvent 'ethanol-ethyl acetate'. In order to assess allelopathy activity for potential weed management purposes, a bioassay was performed with four weed species including Abutilon avicennae, Digitaria sanguinalis, Amaranthus retrqflexu, and Echinochloa crus-galli. A germination study indicated that all sorghum extracts had an inhibitory effect on all four-weed species. Bioassay results showed that, the extract obtained by ethanol-ethyl acetate solvent was more effective than other extracts (ethanol, ethanol-chloroform, ethanol-hexane, and ethanol-methylene chloride). In this work, the identification of the best extraction method from sorghum using different solvents could possibly lead to the development of an environmentally friendly natural herbicide for a more sustainable agriculture.
