| Abstract | ||
| The current research aims at studying the effect of the aqueous extract of mint plant (Muntha piperita) on growth of some fungi such as ; Rhizoctonia solani, Aspergillus niger, Aspergillus terreus, Fusarium oxysporum, Fusarium oxysporum f.sp. The extract has been added to the PDA media at four concentrations 25%, 50%, 75% and 100% in addition to the control treatment (standard PDA media only ) . The results show the effectiveness of the aqueous extracts of mint plant in the inhibition of fungal growth . The highest inhibition is at 100% concentration of the extract , at which the growth of Rhizoctonia solani recorded values of colony diameter; 4.49,6.83, and 8.33 cm for the incubation periods of 1,2,or 3 days , respectively , in comparison with Aspergillus terrens which records the lowest growth values ; 1.82, 2.55, and 3.93 cm colony diameter for the same incubation period as above , respectively . However , the fungus Rhizoctonia solani is not affected by the extract treatments, especially after the incubation periods of 4,5,6,or 7 days . The results also show significant effect of the media on fungal growth . The standard PDA medium gives the highest fungal growth values of colony diameter ; 3.65, 49.13, 5.85, 6.64, 7.23, and 7.72 cm for all incubation periods in compare with 100% concentration of the extract which records values of colony diameter; 3.71, 5.07, 5.89, and 6.64 cm for the same incubation periods , respectively . For the interaction , there is a significant effect of the combination of Fusarium oxysporum and 100% concentration of the extract for the incubation period of 1,2,and 3 days , while the combination of Aspergillus niger , and 100% concentration gave significant effect for the incubation period of 4,5,6, and 7 days in comparison with to other treatment . | ||
