Screening of New Molecules of Fungicides against sclerotium Rolfsii, rhizoctonia Bataicola and fusariumsp. Causing Root Rot/wilt Complex of Soybean

The ischolar_main trot/ wilt complex of soybean has become a major production constraint in Karnataka. The associated pathogens causing the ischolar_main rot/ wilt are identified as Sclerotium rolfsii, Rhizoctonia bataicola and Fusarium sp. in northern Karnataka, either in combination of two or more than two pathogens. In vitro screening of fungicides, bioagents and botanicals was taken up to identify an effective molecule against all the three pathogens. In vitro studies revealed that Mancozeb, Carbendazim, Thiophanate methyl, Hexaconazole, Propiconazole, Carbendazim + Mancozeb and Carboxin + Mancozeb were more effective in inhibiting the mycelial growth of all the three pathogens.
