In Vitro evaluation of antifungal activity of Bioactive Compound 2H-FURO [2,3-H]-1-Benzopyran-2-one against seed borne fungi of maize

Antifungal activity of bioactive compound 2HFuro[ 2,3-H]-1-benzopyran-2-one recorded a significant activity at 100-1000 ppm concentration against all the ten Aspergillus species tested. A. flavus recorded complete inhibition at 100 ppm concentration, A. niger at 500 ppm, A. fumigates at 600 ppm, A. flavus oryzae and A. flavus columnaris at 700 ppm respectively. A. ochraceous and A. flavipes recorded complete inhibition at 900 ppm concentration. Compared to synthetic fungicide Captan and Thiram at 2000ppm concentration. Minimum Inhibitory Concentration (MIC) of bioactive compound was in the range of 100- 900ppm concentration against all the test fungi.
