Abstract:
The aim of this work was to evaluate efficacy of nano formulation and fungicides against Banded Leaf and Sheath Blight in maize to identify the effective management tools. For this purpose two field and lab experiments were conducted during 2020 and 2021. A significant reduction in the severity of the symptoms of Rhizoctonia solani was found after the use of Azoxystrobin + tabuconazole (100% reduction in Mycelial growth) and Azoxystrobin (100% reduction), control of BLSB of maize In vitro at 250, 500 and 750 PPM, whereas minimum mycelial growth inhibition recorded 68.89 percent in Fluxopyroxad + Pyraclostrobin followed by Sedexane with 67.50percent respectively. Under artificially inoculated conditions in field in both tested seasons kharif 2020 and 2021, Azoxystrobin + tabuconazole and Azoxystrobin were provided best efficacy by minimum PDI and disease rating with maximum grain yield. However, this positive effect was still evident variations in effectiveness of fungicides were observed during the same treatment in repeated trials.
