Abstract:
The field experiment was conducted during rabi season 2018-2019 in order to evaluate the Management by biorational Insecticides against of gram pod borer (Helicoverpa armigera hub.) in chickpea (Cicer arietinum L.). Gram pod borer (Helicoverpa armigera Hub.) is a serious pest of chickpea which is injurious to pulses crop of India and in the world also, however it is qualitative and quantitative loss and therefore, management of gram pod borer population by spraying of Helicoverpa armigera nuclear polyhedrosis virus (HaNPV), Bacillus thuringiensis (Bt.), Beauveria bassiana (BB), NSKE 5%, HaNPV + Bt., Beauveria bassiana+ NSKE, Bacillus thuringiensis+ HaNPV+ Beauveria bassiana. Helicoverpa armigera nuclear polyhedrosis virus (HaNPV) + Bacillus thuringiensis (Bt.) becomes imperative to minimize the larval population of gram pod borer. Further it was noted that there was lowest damage range i.e. 2.00, 1.33 and 1.67 was recorded at the first spray and 1.67, 1.00 and 1.33 was found at the second spray.
