Abstract
Twenty-eight cyanobacterial strains were isolated from IARI rice field soil samples, which included eight genera. These strains were screened for algicidal activity using lawn of Synechococcus Synechocystis. Out of twenty eight strains only four strains showed inhibition zones indicative of algicidal activity and these strains belong to the genera Nostoc (Ni, N2), Oscillatoria and Phormidium . Such algicidal compounds play a significant role in the abundance of the organisms and have immense potential as biocidal agents in agriculture and industry.
