Field Efficacy of Insecticides and Botanicals for Management of Spotted Stem Borer (Chilo partellus) on Maize (Zea mays L.)

Abstract

The field investigation was conducted during the Kharif 2021 and 2022 at the Central Research Farm (CRF) of Naini Agriculture Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh, India. The experiment was organized in a Randomized Block Design, comprising twelve treatments, each replicated thrice. The treatments included Chlorantraniliprole 18.5 SC (0.5 ml/l), Lambda cyhalothrin 2.5% EC (10 ml/l), Thiamethoxam 25 WG (10 gm/kg), Profenophos 50 EC (3ml/l), Cypermethrin 10 EC (4 ml/l), Neem oil 3% (30 ml/l), Verticillium lecani 1.15 WP (15 ml/l), Spinosad 45 SC (0.3 ml/l), Emamectin benzoate 5 SG (0.40 gm/kg), Indoxacarb 15.8 EC (1.5 ml/l), NSKE 5% (50 ml/l), and control plot. The results showed that the lowest population of stem borer was identified with Emamectin benzoate 5 SG (2.24), (0.82) and (3.61), (2.33) followed by Chlorantraniliprole 18.5 SC (2.41), (1.01) and (3.82), (2.46) during the Kharif seasons of both 2021 and 2022. Neem oil 3%, NSKE 5% were found to be least effective over the other treatments and is significantly superior over the control.
