Abstract


A field experiment was conducted during kharif 2006-07 and 2007-08 at Agricultural Research Station, Dharwad Farm to evaluation of fungicides, Taqat 500g/ha, Taqat 750g/ha and propiconazole @ 0.1 per cent were effective in controlling the foliar diseases. Maximum yield of 2287.45 kg per hactare was recorded in Taqat 750g/ha. Seed treatment with P. fluorescens @ 10 g per kg + foliar spray @ 0.2 per cent on 30, 40, 50, 60, 70, 80 and 90 DAS, seed treatment with P. fluorescens @ 10 g per kg + foliar spray @ 0.2 per cent on 30, 50, 70 and 90 DAS, seed treatment with P. fluorescens @ 10 g per kg  + foliar spray @ 0.2 per cent on 30, 60 and 90 DAS, Copper oxychloride (0.3%) + Streptocycline Sulphate (0.05%) gave better control of the foliar diseases than fungicidal treatments. Maximum yield of 2227.27 kg per hactare was recorded in the seed treatment with P. fluorescens @ 10 g per kg + foliar spray @ 0.2 per cent on 30, 40, 50, 60, 70, 80 and 90 DAS and was significantly higher over the control.
