Management of okra powdery mildew through agrochemicals

Abstract

To know the field performance of selected phytoproduct, phytoextracts, fungicides and insecticide against powdery mildew disease the field experiment was conducted at N. M. College of Agriculture Farm during late Rabi season of the year 2014-15 and 2015-16. The results showed that hexaconazole @ 0.005% recorded highest per cent disease control (92.48 %) of powdery mildew followed by wettable sulphur @ 0.2% (87.21 %), triazophos @ 0.05% (79.68 %) and trifloxystrobin 25% w/w + tebuconazole 50% w/w @ 0.5% (78.86 %). Whereas, Cassia tora seed extract @ 1% (61.33 %), C. tora leaf extract @ 1% (59.79 %) and neem oil @ 0.0006 (58.33 %) showed the fungicidal effect and minimized the disease. Similarly, significantly higher fruit yield was recorded in fungicidal treatment of hexaconazole @ 0.005% and triazophos @ 0.05% in comparison to other treatments.
