Abstract:
This study was conducted at the laboratory of the Plant Pathology,
Department of Plant Protection, College of Agricultural Studies, Sudan
University of Science and Technology to evaluate the effect of Jatropha
curcas L. seeds and leaves aqueous extract on two fungi, Fusarium solani
and Aspergillus niger in culture media compared to control under laboratory
conditions.
Three concentrations of seeds and leaves aqueous extract (5ml, 2.5ml,
and 1.25ml) were used in addition to a control treated with sterile distilled
water.
VII
The results obtained showed that both extracts from seeds and leaves
and at all concentrations exhibited an inhibitory effect on the growth of the
two fungi tested compared to control. The highest inhibition effect was
obtained at 5ml concentration of extract seeds as well as of leaves on each of
the two fungi.
Generally, the inhibition zone increase with the increase in
concentration of each extract. However, the inhibitory effect of seeds extract
on both fungi was more pronounced than that of leaves.
In conclusion, this study showed that Jatropha seeds and leaves contain
antifungal properties that could be investigated in further studies.
