Effect of application of borogold (Combination of nano silver particles peroxy acid) on management of sheath blight of Rice

Abstract

Sheath blight disease in rice has caused major crop losses in worldwide. Managing the causal agent of disease Rhizoctonia solani Kuhn is difficult because of its broad range and formation of sclerotia which can survive in harsh environmental condition; therefore developing innovative disease management methods without application of hazardous chemicals has been considered as the main concern to maintain sustainable agriculture. The present research revealed to control sheath blight disease of rice by application of Borogold (SNSp). The tested silver nanoparticles 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 59.07% decrease the disease over control treatment followed by T6 (No root dipping or two spray or borogold, whereas the maximum disease severity 47.40% was recorded under T7 (control).
