Abstract

A field trail was conducted at Central Research Farm (CRF), Naini, Prayagraj during Kharif from July to November 2021 in Randomized Block Design (RBD) with three replications. Eight treatments were evaluated against Earias vittella i.e., Flubendiamide @480% SC, Indoxacarb @ 14.5% SC, Spinosad @ 45% SC, Chlorantraniliprole 18.5% EC, Neem oil @ 2%, Emamectin benzoate @ 5% SG, Cypermethrin @ 25% EC and untreated Control.Results revealed that, among the different treatments lowest per cent infestation of okra shoot and fruitborer was recorded in Chlorantraniliprole 18.5% EC (8.02%,5.15%). Emamectin benzoate 5% SG (9.26%, 6.75%) was found to be the next best treatment followed by Flubendiamide@480% SC (10.29%, 7.48%), Cypermethrin@25%EC (11.41%,9.24), Indoxacarb @14.5% SC (12.32%,10.00%), Spinosad @ 45% SC (13.13%, 11.53%) whereas Neem oil @ 2% (14.25%,12.70) was found to be least effective against this pest. Among the treatments,  Chlorantraniliprole 18.5% EC gave the highest marketing yield and cost benefit ratio (188 q/ha and 1:8.41) followed by Emamectin benzoate 5% SG (176 q/ha and 1:8.41), Flubendiamide @ 480% SC (152q/ha and1:7.18), Cypermethrin @ 25% EC (135q/ha and1:6.22), Indoxacarb @ 14.5% SC (121.2q/ha and1:5.74), Spinosad @ 45% SC (114.6 q/ha and 1:5.29) and Neem oil @ 2% (102.4 q/ha and 1:4.80) as compared to control plot (87.2 q/ha and 1:4.2).
