Comparative Efficacy of Selected Chemicals and Bio-pesticides Against Gram Pod Borer [Helicoverpa armigera (Hubner)] on Chickpea (Cicer arietinum L.)

Abstract

The experiment was conducted at Central Research Farm (CRF), Sam Higgin bottom University of Agriculture Technology and Sciences, Prayagraj during Rabi season in 2023-24. The experiment was carried out in Randomized Block Design (RBD) with eight treatments viz., Neem oil 2% @ 2ml/lit, Beauveria bassiana 1×1010 conidia/ml @ 2gm/lit, Profenofos 40% + Cypermethrin 4% @ 3ml/lit, Bacillus thuringiensis @ 2gm/lit, Indoxacarb 14.5 SC @ 0.5ml/lit, Spinosad 45 SC @ 0.5ml/lit, Emamectin benzoate 5% SG @ 1gm/lit and untreated control, with three replications. The data recorded on larval population of pod borer (Helicoverpa armigera) on third, seventh and fourteen days after two sprays revealed that Emamectin benzoate 5% SG was superior among all treatments with larval population of 2.12 and with highest cost benefit ratio and marketable yield of 1:3.65 and 29.16q/ha, followed by Spinosad 45 SC with a larval population of 2.42 and cost benefit ratio and yield 1:3.14 and 26.66 q/ha, Indoxacarb 14.5 SC with a larval population, cost benefit ratio and yield of 2.57, 1:3.12 and 25.83 q/ha, Profenofos 40% + Cypermethrin 4% EC with a larval population,cost benefit ratio and yield of 2.79, 1:2.81 and 22.5 q/ha, Bacillus thuringiensis @ 5mg/ml with larval population, cost benefit ratio and yield of 3.04, 1:2.79 and 21.25 q/ha, Beauveria bassiana @ 1×1010 conidia/ml with a larval population, cost benefit ratio and yield of 3.25, 1:2.26, 17.08 q/ha.
