Abstract: The present investigation was undertaken to find out suitable and low cost substitute for the management of Helicoverpa armigera (Hubner) on chickpea by using microbials and botanicals. The field trial was laid out in the premises of Insectary, Entomology Section, College of Agriculture, Nagpur, during the rabi season of 2013-14. The experiment was laid out in randomized block design (RBD) with three replications and eight treatments including control (water spray). The observations were recorded on average per cent pod damage caused by Helicoverpa armigera (Hubner) and average grain yield of chickpea. The observations on percent pod damage at harvest stage indicated that pod damage ranged from 18.64% to 38.85%. The treatments spinosad 45 SC 0.01% (18.64%) and quinolphos 25 EC 0.05% (21.24%) recorded lowest pod damage and afforded the best protection against Helicoverpa armigera (Hubner) by reducing 18.64 per cent and 21.24 per cent pod damage respectively on harvest as compared to control (38.85%). The treatments spinosad 45 SC 0.01%, quinolphos 25 EC 0.05% and HaNPV 500 LE/ha 1ml/l had shown similar effect and recorded 15.23,14.22 and 12.68 q/ha grain yield respectively, as compared to control 7.45 q/ha.
