The study was carried out to evaluate the efficacy of fungicides and bio-agents against the blast and brown spot disease in basmati rice under in vitro condition. All three fungicides (Tricyclazole75% WP, Propiconazole 25% EC and hexaconazole 5% EC) were found quite effective against the blast and brown spot disease of basmati rice. These fungicides were tested at three different concentrations i.e. 25 ppm, 50 ppm and 100 ppm. The bio-agents (Trichoderma harzianum and Pseudomonas fluorescence) were less effective as compared to fungicides. Among the evaluated fungicides propiconazole shows maximum mycelium inhibition percent of P. oryzae both 25ppm and 50ppm concentration level that was 64.44% and 76.30% while at 100ppm concentration tricyclazole (87.41%) shows maximum inhibition percent. Hexaconazole was most superior and shows maximum mycelial growth inhibition of H. oryzae at all above three concentration of fungicide. Among the eco-friendly treatment P. fluorocens expressed better bio-agent against P. oryzae and H. oryzae as compared to T. harzianum.
