Studies on Management of tomato fruit borer (Helicoverpa armigera (Hubner) by chemical insecticides and neem products were carried out during Rabi season of 2015-2016 at Central Research Farm, Sam Higginbottom Institute of Agriculture, Technology and Sciences (Deemed to be University), Allahabad. The seasonal incidence of fruit borer (Helicoverpa armigera) from 1^st week of October with 2.81% damage which gradually increased and reached to its peak level with 39.54% fruit damage at 42^nd week of March. It was found that fruit borer infestation on damage increased but mean weather parameters lad no effect on the incidence of Helicoverpa armigera only maximum temperature showed positive correlation with fruit damage. Among the data on present infestation of fruit borer after first spraying results were statistically significant. The lowest infestation of fruit borer were recorded in treatments Profenophos 50%EC (4.350), Spinosad 45%SC (5.370), Deltamethrin 2.8%EC (5.90), NSKE (5.90), Chlorantraniliprole 18.5%SC (6.550), Neem oil (6.650). However all these treatments were superior over control. The maximum yield was reported Neem oil (15 q/ha), followed by NSKE (13.00 q/ha), Deltamethrin 2.8%EC (14.00 q/ha), Profenophos 50%EC (16.00 q/ha), Chlorantraniliprole 18.5%SC (12.00 q/ha), Spinosad 45%SC (13.00 q/ha).
