Groundnut is one of the most important economic oilseed crops of the world. It belongs to the family leguminosae and mostly infected by several fungal, bacterial and viral diseases among which Stem rot caused by Sclerotium rolfsii is considered as one of the most destructive diseases in the groundnut growing areas. An experiment was conducted to check efficacy of few selected essential oils and Trichoderma viride against Sclerotium rolfsii on field conditions. Three types of essential oils viz., Neem oil, Clove oil, Eucalyptus oil and one bio-agent viz. Trichoderma viride were selected @ 5 percent concentration as seed treatment. The other three treatments were the combination of each selected oil with the taken bio-agent viz. Neem oil @ 5 % + Trichoderma viride @ 5 %, Eucalyptus oil @ 5 % +Trichoderma viride@ 5 % and Clove oil @ 5 % +Trichoderma viride@ 5 %. An untreated replication served as control. Readings for disease incidence, growth parameters were taken at desired no of days. On field conditions, among all the treatments Clove oil @ 5 % +Trichoderma viride@ 5 % showed the most significant results followed by Eucalyptus oil@ 5 % +Trichoderma viride@ 5 % and Clove oil @ 5 %. The lowest inhibition was seen in control plot. Subsequently benefit cost ratio was also most desirable with Clove oil @ 5 % + Trichoderma viride@ 5 %.
