| Abstract | ||
| Preliminary phytochemical screening of the three plants; Anabasis articulata Forssk., Salsola kali L. and Cornulaca monacatha Del. showed that these plants contained flavonoids, phenolics, glycosides and/ or carbohydrates, sterols, terpenes, tannins, alkaloids and saponins. The active constituents present in ethyl alcohol (96 and 70%) and water extracts with high percentages in the three plants. Anabasis articulata plant contained the higher percentages of saponins and alkaloids, while the plant S. kali contained the higher percentage of flavonoids and tannins. Three compounds of alkaloids were isolated from Anabasis articulate, while Co. monacatha contained two alkaloid compounds . In greenhouse experiments, interaction between plant extracts, crown gall bacteria and Fusarum oxysporum, F. lycopersici were studied on tomato plants using the selected plant extracts in different solvents. S.kali plant extracted with ethyl acetate and Carnulaca monacatha extracted with ethyl alcohol 70%. The two medical plants have the greatest effect on reducing the incidence of wilt especially in fertilized treatments. On the other hand, Anabasis articulata extracted with ethyl alcohol 70 % and Cornulaca monacatha extracted with ethyl acetate and petroleum ether have the greatest effect in reducing the size and weight of galls. | ||
