In vitro evaluation of twelve phytoextracts (aqueous and methanolic extract) of locally available plants having antimicrobial properties were done against Rhizoctonia solani, Kuhn by sequentially highering the concentration of the extracts i.e. at 1%,2.5%, 5% and 10%. The poisoned food technique employed for the purpose.Among all phytoextracts, clove extracts of garlic gave highest inhibition against the fungal growth in all concentrations of its both solvent extracts i.e. 43.23% to 82.73% in aqueous extract and 51.50% to 90.27% in methanolic extract followed by turmeric and datura respectively. The highest radial growth inhibition was achived by methanolic extract of garlic @ 10% (90.27%) followed by its aqueous extract(82.73%) and turmeric aqueous extract(65.23%) respectively in the same concentration. The best performing phytoextracts were tested in vivo in pot culture and in the field(2018 kharif & 2019 kharif) to confirm their efficacy against the fungus inciting sheath blight in rice. The garlic methanolic extract was treated along with its nano-emulsion in vivo condition and nano-emulsion of methanolic extract was found most effective by reducing the percent disease index in both the years(2018 kharif and 2019 kharif). Carbendazim 50WP(1l/lit) was used as standard fungicide for comparison.
