The study of the antifungal potency of Citrus Limon seed powder extracts against a fungal strain Fusaruim spp. allowed to view a more interesting inhibitory activity of the methanol extract compared to the ethanol extract, acetone extract and aqueous extract. This is due to the variability of the chemical composition of each extract. The Fusaruim spp. showed a sensitivity for the four plant extract powder with a diameter of 26 mm to 30 mm methanol and ethanol extracts and for 31mm to acetone and aqueous extract of the minimum concentration 300μl (52,30 to 60 %). Statistical analysis shows that the mycelial growth of the control level was significantly higher than that observed on the boxes of treatment. The extracts tested appear to contain interesting bioactive compounds for inhibitory activity development Fusaruim spp. These bioactive compounds are produced in response to microbial infection in plants such as terpenoids, glycostéroïdes, flavonoids and polyphenols.
