Allelopathy investigations can be an opportunity to make new generation of Bioherbicides and growth inhibitors.To investigate the Allelopathic effect of six medicinal plants (Artemisia absinthium, Datura stramonium, Eucalyptus globolus, Hypericum perforatum, Nerium oleander, Salvia officinalis) on three current weed species in Iran (Amaranthus retroflexus, Chenopodium album, Portulaca oleracea), three factorial experiment, each by 3 factors (Weed Species in 3 level, Medicinal Plants in 6 levels and Extract Saturation in 4 Levels 100%, 70%, 40% and distilled water as control) conducted on completely randomized design. One of the experiments was conducted as pre-emergence and two other was done as post emergence. Results showed that the Eucalyptus globolus has the inhibitoriest effect between studied medicinal plants. In addition, the allopathic effect of extracts increased by increasing the saturation. According to the grouping medicinal plants in 3 main groups (Essential oil plants group containing Eucalyptus globules and Salvia Officinalis, Alkaloid plants group containing Datura stramonium and Nerium oleander and Flavonoid plants group containing Artemisia Absinthium and Hypericum Perforatum), this result obtained that Essential Oil Plants, have greater allopathic effect in comparison of two other groups. Results also showed that the pre-emergence factors are more affected by medicinal plants extracts, rather than post emergence factors.
