Title : Field Efficacy of Biorational Insecticides Based Modules for the Management of Helicoverpa armigera (Hübner) in Chickpea

Abstract :

Experiments were conducted at Banda University of Agricultural & Technology, Banda in 2018-19 and 2019-2020 to evaluate the field efficacy of biorational insecticides-based modules consisting Azadirachtin, NSKE, Bt, NSKE and Indoxacarb against Helicoverpa armigera in chickpea. The Indoxacarb 15.8 EC @ 50 g a.i./ha + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha was found most effective and in reducing H. armigera population. The field treated with this module recorded least pod damage 1.68% and 1.27% during 2018-19 and 2019-20, respectively. Data revealed that the fields treated with Indoxacarb 15.8 EC @ 50 g a.i./ha + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha recorded highest yield of 21.3 q/ha & 22.82 q/ha during both the year and found to be the best treatment. The maximum cost benefit (C: B) ratio of 1: 5.33 and 1: 8.17 was obtained from Indoxacarb 15.8 EC + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha during 2018-19 & 2019-20, respectively.
