| Abstract |
Evaluate the purity tests of Calendula officinalis as dry part (flowers) and prepare formulation of the plant extract in two solvents, ethanol and methanol to be used as an anti-fungal against Al. solani, F. oxysporuim, R. solani and S. rolfsii.
Two experiments were carried out to evaluate the fungicidal effect of C. officinalis plant extract. The first experiment was carried out to determine the fungicidal effect of different concentrations 25, 50, 75 and 100 g/ ml of C. officinalis plant extract in two solvents ethanol and methanol on the linear growth of the fungi under investigation. The second experiment was performed in the greenhouse under the artificial infestation condition with R. solani causing damping-off and S. rolfsii causing southern blight diseases for tomato seedling. Tomato seeds variety Castle rock were applied by 1125 g/ kg. C. officinalis plant extract or fungicide carboxin (Vitavax) as seed treatment. Results of in vitro experiment showed that the C. officinalis plant extract in the different concentrations decreased the mycelial growth for all fungi under investigation. C. officinalis plant extract in ethanol solvent was more effective than in methanol solvent against all fungi under investigation.
Greenhouse experiment showed that the tomato seed treatment with carboxin (Vitavax) gave the highest protection against R. solani and S. rolfsii followed by C. officinalis plant extract in ethanol solvent.
