Abstract:
In vitro efficacy of seventeen new molecules of fungicides were evaluated against Bipolaris setariae causing leaf blight on browntop millet at University of Agricultural Sciences, GKVK, Bangalore in order to find out effective fungicide against B. setariae. Mancozeb, among the six contact fungicides recorded cent per cent inhibition over control at 500 and 1000 ppm with mean inhibition of 96.54 per cent. Among the six systemic fungicides tested at 50, 100 and 150 ppm, propiconazole exerted 100 per cent inhibition of mycelial growth followed by tebuconazole which accounted 100 per cent inhibition at 100 and 150 ppm with mean inhibition of 94.69 per cent and cymoxanil + mancozeb among the five combi-product fungicides tested (100, 250 and 500 ppm) exhibited maximum (79.01 %) mean inhibition of mycelial growth. Among all groups, tricyclazole was found to be least effective.
