Emex spinosus L. (Family Polygonaceae), a decumbent, branched annual herb, was assayed for its allelopathic potential because of it weedy habit. Aqueous extracts were obtained from powdered shoots and leaves at room temperature and by boiling. Various extracts significantly inhibited the germination and seedling growth of Triticum aestivum and Brassica compestris used as test species. The extracts reduced the development of cells and retarded cell division in root tip. Results revealed that the E. spinosus L. has a strong allelopathic potential at least against tested species. The phytotoxicity depended upon the test species and concentration of extract.
