The present study investigate the effect of six medicinal rhizosphere blue greens and their aqueous root extract on the growth of plants extract have slight inhibitory effect on the growth of Cyanosarcina significantly decreased by increasing the concentrations of the root extract of all Cyanosarcina fontana that was very sensitive and completely disappearance around the root zone from all tested plants. Qualititative analysis of some phytochemical investigated plants extract contained alkaloids, proteins, carbohydrates, and plants, Verbesina encelioides, Glinus lotoides, Helotropium supinum, constituents of these medicinal plant roots are taken into our consideration. All investigated plants extract contained alkaloids, proteins, carbohydrates, and terpenoides. While tannins were recorded only in aqueous extract of Mentha microphylla. Results indicated that, the total number of blue greens was Mentha microphylla, Juncus subulatus and Pulicaria undulate on the diversity of plants, greatly reduced around these plant roots. Addition of 1% and 3% of all aqueous root fontana. In general, the total carbohydrates, total proteins, and total lipids were tested plants.
