The antifungal activity of different extracts of Astericus Imbricatus against botrytis cinerea isolated from tomato show that the percentage of the inhibition was almost100% for the four extracts of organic solvents at 500 ppm. At 250 ppm the percentage of inhibition was almost 70% for the ether extract and for the chloroform extract, 60 % and 50% for the ethyl acetate extract and for methanol extract, respectively. While the aqueous extract of Astericus Imbricatus exhibited moderate antifungal activity. The corrosion inhibition by an Astericus Imbricatus extract (AIE) on C38 steel in hydrochloric acid (HCl) solution has been investigated by electrochemical methods and weight loss. Potentiodynamic polarization studies clearly reveal that the presence of AIE does not change the mechanism of the hydrogen evolution reaction and they act essentially as cathodic and anodic inhibitor. Inhibition efficiency of AIE reached 96.33% at 0.6 g/l. The adsorption of AIE on C38 steel surface obeys the Langmuir isotherm.
