<jats:title>Abstract</jats:title><jats:p>The effects of water extracts of Chenopodium album leaves and roots on the growth of grass weed (Setaria viridis) and broad leaf weed (Corchorus olitorius) grown with beans (Phaseolus vulgaris) in greenhouse pots were studied in the National Research Centre, Giza, Egypt. In this experiment fresh leaf and root extracts and their corresponding dry leaf and root extracts at different concentrations were used. There were significant inhibitions in the dry weights of S. viridis and C. olitorius by all extracts at the flowering stage of beans and at harvest. The inhibition effect of all C. album extracts on both weeds (dry weight/pot) depended on the extracted plant organ (leaf or root), its fresh or dry form as well as its concentrations. The inhibition caused by the leaf extract was much higher on weed growth than that of root extract. A higher concentration of fresh leaf extract (25%) had the highest significant inhibition effect. The results also indicated that C. olitorius was more sensitive to the extracts than S. viridis. On the other hand, the inhibition effect of the extracts on the growth of both weeds was accompanied by increased bean growth and yield/plant. The analysis of both leaf and root extracts of C. album revealed that the total content of polyphenols and flavonoids in the leaf extract was more than triple that of the root extract. The results suggested that the fresh leaf extract of C. album may be a possible tool for the development of weed control using natural herbicides.</jats:p>
