Organic extracts (Chloroform, ethyl acetate and hexane) of three normal and pesticide adapted strains of blue green algae (BGA) were investigated for their antifungal activity against the fungal pathogens of rice. The pesticide adapted strains showed better antifungal activity when compared with the normal strains. The maximum zone of inhibition was 14mm, 21mm, and 22mm for Fusarium fujikori, Rhizoctonia oryzae and Curvularia oryzae. The percentage of activity increased when compared with the control strains were 12.3, 5.3 and 6.6percentage repectively.
