Description An experiment was conducted during rabi season in 2007-08 and 2008-09 to find out appropriateScheduling of fungicidal sprays for the management of powdery mildew of cumin. Significant differenceswere observed amongst various fungicidal spray schedules for disease intensity, yield, volatile oil and1000-seed weight. The treatments with two sprays of difenaconazole @ 0.05 per cent and two spraysof wettable sulphur @ 0.2 per cent were at par with three sprays of difenaconazole @ 0.05 per cent andwettable sulphur @ 0.2 per cent with respect to per cent disease intensity, seed and oil yield and 1000-seed weight. Thus, two sprays of difenaconazole (0.05 %) proved most effective in reducing diseaseand recorded 19.05 per cent disease intensity with higher reduction in disease (67.24 %) over controland also gave higher yield (522.8 kg h -1), volatile oil (4.11 %) and 1000-seed weight (2.62 g). But on thebasis of economic analysis, two sprays of wettable sulphur @ 0.2 per cent from disease onset andthereafter at an interval of 17 days with the higher profit (Net ICBR 1:10.86) was observed best to twosprays difenaconazole @ 0.05 per cent (Net ICBR 1:0.57) with respect to disease intensity (21.02 %) andoverall yield followed by three sprays of of wettable sulphur @ 0.2 per cent (Net ICBR 1:7.18), twosprays of hexaconazole @ 0.05 per cent (Net ICBR 1:6.64), two dusting of sulphur (Net ICBR 1:6.06) andmancozeb 0.25 per cent.
