The root trot/ wilt complex has become a major production constraint in Karnataka. The associated pathogens causing the root 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.
