The present field studies were conducted during kharif 2016 to determine the field efficacy of selected insecticides and neem products against shoot and fruit borer [Earias vittella (Fabricius)] on okra [Abelmoschus esculentus (L.) Moench]” at Central agriculture field, SHUATS (Sam Higgin bottom University of Agriculture, Technology and Sciences), Allahabad, Uttar Pradesh (India). Studies revealed that maximum mean pest population recorded in control and all the treatments were found effective in reducing the infestation of shoot and fruit borer as compared to control, while it was found minimum in insecticides treated plots as compared to neem product treated plots. Among the treatments application of Rynaxypyr 20 SC @ 20 g.a.i. /ha was found superior in recording less infestation of pest on shoot and fruit of okra (2.25%) and (3.80%). Followed by Cypermethrin 10% EC (2.74%) and (4.12%), Flubendamide 480 SC (4.65%) and (5.38%), Spinosad 45% (5.01%) and (5.39%), Cypermethrin + neem oil (6.25%) and (6.76%), Neem oil (8.25%) and (9.19%), NSKE (8.933%) and (9.95) respectively.
