Management of alternaria leaf blight of groundnut through fungicides
Author(s): HJ Kapadiya
Abstract: A field trial was carried out at Main Oilseeds Research station, Junagadh Agricultural University, Junagadh during summer2011 to 2015 to know the effect of various fungicide against alternaria leaf blight and their impact on groundnut pod yield. Seven treatments viz. mancozeb @ 0.2%, copper oxychloride @ 0.2%, hexaconazole @ 0.0075%, tebuconazole @ 0.0375%, difenoconazole @ 0.025%, propiconazole @ 0.025% applied three time at 35, 50 and 65 days after sowing (DAS) including one control were imposed. Among the different fungicide, mancozeb @ 0.2% three sprays at 35, 50 and 65 days after sowing were recorded minimum disease (22.95%), maximum pod (1873 kg ha-1) as well as haulm (4648 kg/ha) yield under the under the field condition followed by difenoconazole @ 0.025% three sprays at 35, 50 and 65 DAS which reducing alternaria leaf blght (24.47%), increasing pod (1846 kg ha-1) and haulm (4619 kg ha-1) yield. Moreover, on the basis of net realization per hector, mancozeb @ 0.2% obtained highest earning (Rs.14215), highly effective, economical in reducing alternaria leaf blight disease of groundnut followed by three sprays of difenoconazole @ 0.025% and hexaconazole @ 0.0075% with Rs. 9230 net realization noted in both the fungicide.
