Abstract: | The aim of our study is to use plant extracts as bio fungicides on Mauginiella scaettae causal agent of the date palm inflorescences rot . The antifungal activity of these extracts is tested by the micro- dilution method in a solid environment in order to calculate the antifungal index. The extraction method allowed us to obtain a return, the highest of which is that of Pomegranate peelers (1.66%) followed by Lantana camara (0.065%) then the lowest castor (0.043). The results of the antifungal activity show that the methanolic extracts of the three plants have a biological control potential of M. scaettae. The effectiveness of each methanolic extract is tested for different concentrations (5%, 10%, 20%, 50%, 100%) and estimated by the growth inhibition rate of the fungus. For the extract of Ricinus communis, the best inhibition rates are observed for the concentrations of 50% and 100% with respective values of 72% and 82% inhibition the Lantana camara extract has a strong inhibitory effect ( 75%) for the 100% concentration. Pomegranate peeler extract has good inhibitory effects at 50% and 10% concentrations with inhibition rates of 72% and 82% respectively. The result with which we concluded in this work is that extracts of Punica granatum show a good fungistatic effect against M.scaettae fungi compared to the two extracts Lantana camara and Ricinus communis. |
