Abstract:
The field trial was conducted at Naini Agricultural Institute, Prayagraj during the kharif season of 2022 at Central Research Farm, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, (U.P). Eight treatments including control were evaluated against Earias vittella (F) i.e.,(T₁) Chlorantraniliprole 18.5% SC @0.5ml/lit, (T₅) Spinosad 45% SC @0.4ml/lit, (T₂) Fipronil 5% SC @1ml/lit, (T₃) Imidacloprid 17.8% SL @0.3ml/lit, (T₇) Metarhizium anisopliae (CFU 1×10⁸) @4gm/lit, (T₄) Nisco sixer plus @2ml/lit, (T₆) Neem oil 1500 ppm @2ml/lit, (T₀) untreated control. Each insecticide was sprayed twice at 15 days interval. All the insecticide tested significally reduced the pest infestation compared to untreated control. The lowest percent of shoot and fruit borer infestation were observed Chlorantraniliprole (9.37% and 6.45%) after first and second insecticidal application respectively, which is followed by Spinosad (10.54% and 6.96%), Fipronil (11.12% and 7.85%), Imidacloprid (11.94% and 9.07%), Metarhizium anisopliae (12.71% and 9.31%), Nisco sixer plus (13.19% and 9.57%), Neem oil (14.10% and 10.34) and Untreated control (19.81% and 25.11%). Among all the treatment cost benefit ratio were reported best and most economical in Chlorantraniliprole 18.5% SC (1:4.89), followed by Spinosad 45% SC (1:4.45), Fipronil 5% SC (1:4.44), Imidacloprid 17.8% SL (1:3.97), Metarhizium anisopliae CFU 1×10⁸ (1:3.41), Nisco Sixer plus (1:2.89), Neem oil 1500 ppm (1:2.76), untreated control (1:1.93).
