ABSTRACT
The present in vitro study was carried out at the Department of Plant Pathology, University of Agricultural Sciences, Dharwad, Karnataka, India to evaluate the efficacy of various fungicides against Rhizoctonia solani (J. G. Kuhn) causing root rot of french bean using poisoned food technique. Among the contact fungicides tested, captan (70.37 %) and chlorothalonil (69.63 %) recorded maximum percent inhibition of mycelial growth and significantly superior over all other treatments. Carbendazim, difenoconazole, hexaconazole, propiconazole and tebuconazole (systemic fungicides) recorded cent per cent inhibition of mycelial growth of Rhizoctonia solani. Cent percent mycelial inhibition was recorded in all the combi product fungicides viz., (carbendazim + mancozeb), (trifloxystrobin + tebuconazole), (tricyclazole + mancozeb), (captan 70 % + hexaconazole 5 %) and (carboxin + thiram) at all the concentrations.
Keywords French bean, root rot, Rhizoctonia solani, fungicides.
