Effect of Selected Insecticides against Earias vittella (Fabricius) on Okra Abelmoschus esculentus L.

At the Sam Higginbottom University of Agriculture, Technology and Sciences in Prayagraj, Uttar Pradesh, India, a field experiment took place out at the Central Research Farm (CRF). Using a variant of Kasturi, the experiment was set up using a Randomized Block Design (RBD) with eight treatments that were each replicated three times. The treatments viz., Lambdacyhalothrin 2.5% EC@0.5-1ml/lit, Spinosad 45%SC @0.3-0.4ml/lit Flubendiamide 480SC @0.3ml/lit, Chlorantraniliprole18.5%SC 0.5ml/lit, Imidacloprid17.8%SL@ 1ml 2.5l, Emamectin benzoate 5%SG@5 g/land Neem oil@ 20 ml/l and along with untreated control were used against fruit and shoot borer (Earias vittella) infesting okra. All treatments have been shown to be significantly superior to control when analyzing the data on the larval population of the fruit and shoot borer of okra after the first and second spray. Among all the treatments Chlorantraniliprole 18.5%SC showed lowest larval population 10.21 and 9.98 by Spinosad 45% SC(11.45,12.29%), Emamectinbenzoate 5% SG(13.86,14.11%), Imidacloprid 17.8% SL(16.94,15.87%) Lambdacyhalothrin 2.5% EC(17.83,16.03%) Flubendamide 480SC (19.25and19.40%) Neemoil 20ml/l (20.35 and18.75%) Control 5% (24.84 and 25.98%). The highest yield and cost benefit ratio was recorded in Chlorantraniliprole 18.5% SC(153q/ha,1:6.54) followed by Spinosad 45% SC(150q/ha,1;6.01) Emamectinbenzoate 5% SG(125q/1;5.54), Imidacloprid 17.8% SL(117q/ha,1:5.28) Lambdacyhalothrin 2.5% EC(105q/ha1:4.83), Flubendamide 480 SC(79q/ha, 1:3.56 and Neemoil 20ml/l (7 0 q / h a ,1:3.03).
