Assessment of allelochemicals potential of peganum harmala L. for biological control of cynodon dactylon L.

الملخص EN

This study was conducted to evaluates the allelopathic potential of Peganum harmala L.

(Zygophyllaceae) on the growth of Cynodon dactylon L.

(Poaceae).

Seeds, stems, and a mixture of (seeds and stems) aqueous extracts of P.

harmala plants were applied as a foliar application to three weeks old seedlings of Cynodon dactylon weeds.

The result indicated that the application of aqueous extracts of different plant parts of P.

harmala caused a significant reduction in growth traits of Cynodon dactylon including plant height, number of branches, number of leaves, and plant weight.

Moreover, the result revealed that the Inhibitory effect of P.

harmala aqueous extract on Cynodon dactylon L was more pronounced in plant height and number of leave plant-1 traits.

In addition, the results illustrated that among the different P.

harmala plant parts used in this study, seeds extract was the most toxic and caused the greatest negative effect on growth traits of Cynodon dactylon.

According to the results, the degree of toxicity of different P.

harmala plant parts can be arranged in the following order: seeds > mixture > stems.

The results of this study concluded that the use of Peganum harmala L plant has the potential to be developed further as a bio herbicide system to control weed such as Cynodon dactylon L.
