Efficacy of chemicals, bio-agents and their compatibility in management of stem rot disease of groundnut


Author(s): DRS Vineela, SK Beura, A Dhal, SK Swain and D Sethi

Abstract: Stem rot of groundnut (Sclerotium rolfsii) causes losses in yield upto 25% and the losses may be accounted for 40-50% in terms of mortality of crop, particularly in kharif groundnut when the climatic conditions are more favourable for pathogens. Management of soil borne pathogens were found difficult, uneconomical and harmful for the environment. Under in vitro investigation on management of groundnut stem rot, Trichoderma hamatum showed highest antagonistic acitivity (75.2%) in dual culture method followed by Trichoderma harzianum (74.7%). Carbendazim 12% + mancozeb 63%, carboxin 37.5% + thiram 37.5%, Triazole group fungicides such as tebuconazole 25.9% SL, hexaconazole 5% EC, difenoconazole 10% WP, propiconazole 25% EC, showed 100% pathogen inhibition in poison food technique followed by Azoxystobin 25%EC (87.26%). Compatibility of bioagents with fungicides reveled that all the three species viz. T. vorode, T. harzianum and T. hamatum were compatible with the chemical azoxystobin.
