The cyanobacteriumNostocmuscorum was isolated from Al-Hassa, Saudi Arabia. Present study has undertaken effectiveness of Nostocmuscorumin different solvent (Petroleum ether, Chloroform, petroleum ether, Methanol) extract against five plant pathogenic fungi namely Alternaria alternate, Aspergillusflavus, Fusariumoxysporum, Rhizoctoniasolani and Rhizopusstolonifer. Different organic extracts were prepared at a concentration of 1mg/disc.The data obtained here showed that high efficiency of the algal culture filtrates in suppressing the fungal mycelial growth. The best results were obtained by culture filterateextract, chloroformic and methanolic extracts of the algal cell pellet. The antifungal activity of the algal culture filtrates and extracts of algal cell pellets may contribute to the presence of bioactive compounds. This study can provide potential candidates for the development of biocontrol agents against these fungi.
