Soybean [Glycine max (L.) Merril] is the world most important legume crop which contributes 25 percent to the global edible oil. Root rot of soybean is an important disease caused by Rhizoctonia bataticola. An experiment was conducted in 2023-24 in which the efficacy of seven different fungicides against Rhizoctonia bataticola was evaluated by poisoned food technique. Among these tested fungicides, Carboxin 17.5%+ Thiram 17.5% at 0.05%, 0.1% and 0.15% concⁿ, Metalaxyl 4% + Mancozeb 64% at 0.1% and 0.15% concⁿ, Carbendazim 50% WP at 0.1% and 0.15% concentrations and Mancozeb 75% WP at 0.15% concⁿ were showed 100 percent inhibition of the mycelial growth of R. bataticola. Whereas the rest of the 3 fungicides, Captan, Azoxystrobin 23% and Thiophonate Methyl were also inhibit the growth of R. bataticola in the range of 70.95% to 90.20% at 0.05%, 0.1% and 0.15% concⁿ. Respectively.
