The aim of the present study was to evaluate the biological potential of three cyanobacterial strains (Nostoc muscorumSpirulina platensis and Anabaena flos-aquae) against soil pathogenic fungi. The different exudates were prepared at concentrations of 25, 50, 75 and 100% and their effects on two soil pathogenic fungi (Fusarium oxysporum and Rhizoctonia solani) were studied. Results revealed high efficiency of the algal culture filtrates in suppressing the fungal mycelial growth diameter. The best results were obtained by Spirulina platensis and Nostoc muscorum. The antifungal activity of the algal culture filtrates may contribute to the presence of bioactive compounds, i.e. total phenolic compounds, IAA and protease enzyme. This study can provide potential candidates for the development of biocontrol agents against these soil pathogenic fungi.
