Screening of Bioagents and Botanicals against Sclerotium rolfsii, Rhizoctonia bataticola and Fusarium Sp Causing Root Rot/wilt Complex of Soybean

The ischolar_main trot/ wilt complex has become a major production constraint in Karnataka. The associated pathogens causing the ischolar_main rot/ wilt are identified as Sclerotium. rolfsii, Rhizoctonia bataticola and Fusarium sp. in northern Karnataka, either in combination of two or more than two pathogens. In vitro screening of bioagents and botanicals was taken up to identify an effective strain/botanical pesticide against all the three pathogens. In vitro studies revealed that Trichoderma viride, Trichoderma harzianum, Azadirachtin, Neem oil were more effective in inhibiting the mycelial growth of all the three pathogens.
