Dry root rot caused by Rhizoctonia bataticola (Taub) Butler, is one of the most widely distributed and destructive disease of soybean [Glycine max (L.) Merril], causing accountable quantitative and qualitative losses. All of the 17 fungicides (seven systemic, six contact and four combi- fungicides) evaluated in vitro were found effective with significant mycelial growth inhibition of R. bataticola, over untreated control. However, carbendazim 50% WP (@ 500, 1000 and 1500 ppm), carboxin 37.5% + thiram 37.5% WP (@ 1500, 2000 and 2500 ppm) and carbendazim 12% WP + Mancozeb 63% WP (@ 2000 and 2500 ppm) resulted with cent per cent (100%) mycelia growth inhibition, followed by Thiophanate methyl 70% WP with average mycelia growth inhibition of 93.57 per cent, Captan 50 % WP (89.48%) and Hexanconazole 5% EC (87.62%), over untreated control.
