The impact of eight concentrations of coumarin (0, 100, 200, 400, 800, 1600, 3200 and 6400 ppm) were separately used as a pre-plant incorporated into soil on six plant species under greenhouse conditions. Generally, coumarin had phytotoxic effect against all plant species. The phytotoxic effect was concentration-dependent. The high concentrations could inhibit the emergence of seedlings (probably by stopping germination of seeds). Based on ED<sub>50</sub> parameter, the ranking of plant species for tolerance to coumarin was <em>S. halepense</em> > <em>Z. mays</em> > <em>C. album</em> > <em>A. retroflexus</em> > <em>E. cruss-gali</em> > <em>P. oleracea</em>.
