Bio efficacy of Selected Systemic and Non Systemic Fungicides invitro and invivo Condition against Banded Leaf and Sheath Blight Disease of Maize caused by Rhizoctonia solani Kühn
Year: 2020
Type: article
Abstract: Ten fungicides were tested at different concentrations in in vitro and in vivo for the management of banded leaf and sheath blight of maize. Thiophanate methyl 70 WP, difenoconazole 25EC, hexaconazole 5 EC and validamycin 3 SL were screened against Rhizoctonia solani at 10, 15, 20 and 25 ppm concentrations for their anti fungal activity. where, as mancozeb 75WP,chlorothalonil 75 WP, zineb 75WP and captaf 50 WP of the fungus at 100,200, 300 and 400 ppm concentrations, respectively along with control. At10 percent concentration difenoconazole, thiophanate methyl, completely check the radial growth of the fungus. Based on effectiveness of fungicides in vitro, they were further tested under in vivo conditions. carbendazim 50 WP @ 0.1 % applied as seed treatment followed by validamycin 3SLfoliar spray showed lower disease severity, highest grain yield followed by 2750Kg/ha @ 0.2 per cent.
