Title: Bio-efficacy of different fungicides in managing blast of rice caused by Pyricularia grisea
Abstract: In vitro evaluation of different fungicides indicated that tebuconazole proved most effective as it completely inhibited the colony growth of P.grisea at 10 μg/ml whereas azoxystrobin + difenconazole, propiconazole and difenconazole completely inhibited the colony growth of the pathogen at 25 μg/ml. rest of fungicides viz. zineb, tricyclazole, kasugamycin and azoxystrobin proved least effective even at a concentration of 200 μg/. under pot culture conditions, tebuconazole @ 0.1 per cent was found to be highly effective in reducing leaf blast severity followed by propiconazole @ 0.1 per cent. Under field conditions, the efficacy of propiconazole, tricyclazole, tebuconazole and azoxystrobin + difenconazole was at par and proved to be effective fungicides in reducing the leaf and neck blast severity and increasing the yield.
