Diseases sample collected , isolation, purification of Rhizoctonia solani. The effect of application of Borogold (combination of Nano Silver Particles Peroxy Acid) on management of sheath blight of rice. Evaluation of “Bacillus subtilis ZB87- 1/21 MTCC” for the management of sheath blight of rice. In the present study, we have evaluated aqueous extracts of commonly available ten plant species belonging to ten families in vitrofor their inhibitory effect on the mycelia growth of Rhizoctonia solani. In this experiment result was found as the lowest mycelial growth of R. solaniwas recorded in clove extract of garlic (Allium sativumL.) which was found significantly superior among all the treatment with lowest mycelial growth of pathogen (25.33 mm). Results in terms of percent growth inhibition of R. solanirevealed that clove extract of garlic produced maximum inhibition (71.85 %) followed by leaf extract of karanj (38.88 %), bulb extract of onion (37.03%), leaf extract of jetropha (30 %). Evaluation of pesticide (fungicide + insecticide compatibility) against sheath blight of rice Invitro study was conducted in plant pathology Uttaranchal University , Dehradun to control sheath blight of rice by application , of Borogold. The tested Borogold i.e., T3 (Root dipping or three spray of borogold), treatment found highly effective in reducing the disease severity of sheath blight, 17.77% and 62.94% decrease of the disease over control treatment was at par with T1 (Root dipping or two spray of borogold), 18.51% reducing the disease severity and 60.94% decrease disease over control and T2 (Root dipping or two spray of borogold + need based spray of borogold), 19.25% reducing the occurrence of disease and 59.07% decrease the disease over control treatment followed by T6 (No root dipping or two spray or borogold), 34.06% reducing the disease severity and 28.14% decrease the disease over control. T5 (No root dipping or two spray of borogold + need based spray of borogold), 35.55% reducing the disease severity and 25.00% decrease the disease over control, where as the maximum disease severity 47.40% was recorded under T7 (control).
