Abstract

The experiment on Field efficacy and economics of different insecticides against tomato fruit borer [Helicoverpa armigera (Hubner)] was conducted during rabi 2021-2022, at Central Research Field, Department of Entomology, SHUATS, Naini, Prayagraj, U.P. The data on percent population reduction of different treatments revealed that the T5 Spinosad 45% SC (81.379) followed by T1 Indoxacarb 14.5% SC (75.140), T7 Emamectin benzoate 5% SG (74.634), T2 Flubendiamide 39.5% SC (68.634), T3 Novaluron 10%EC (65.647), T4 Fipronil 5% SC (54.225), T6 Neem oil 0.03% EC (49.533) found to be least efficient than all other treatments. Among the treatments studied the best and most economical treatment was Spinosad (1:6.72), Indoxacarb 14.5% SC 14.5SC (1:6.42), followed by Emamectin benzoate 5% SG (1:6.3), Novaluron 45% SC (1:5.09), Flubendiamide 20% WG (1:4.45), Fipronil 5% SC (1:7.9), (1:3.92), Neem oil 0.03% EC (1:3.45) as compared to control T0 (1:3.04).
