Abstract:
The investigations on “Grain yield and incremental cost benefit ratio (ICBR) biorational insecticides against Helicoverpa armigera in chickpea” were carried out at the Student’s Instructional Farm, C. S. Azad University of Agriculture and Technology, Kanpur during Rabi season 2021-22 and 2022-23 with three replications and eight treatments of biorational insecticides, against Helicoverpa armigera. The biorational insecticides like HaNPV, Nimbecidine, Bacillus thuringiensis, Beauveria bassiana, Dhatura leaf extract, Spinosad and Indoxacarb, in reducing the infestation of pod borer, Helicoverpa armigera and providing a higher net return per rupee invested. The higher grain yield of 20.10 q/ha and 19.70 q/ha was recorded with the application of spinosad 45% SC (Tracer) @ 84.375 g/ha during both years. The most favourable cost benefit ratio was obtained from the plot treated with spinosad 45% SC (Tracer) @ 84.375 g/ha 1:13.98 and 1:14.80 followed by indoxacarb 14.5% SC @ 75g/ha 1:8.51and 1:8.79, Bacillus thuringiensis @ 1.5 kg/ha 1:7.62 and 1:7.50, nimbecidine @ 2% 1:6.38 and 1:6.53, HaNPV @ 300LE/ha. 1:5.23 and 1:5.38, Beauveria bassiana @ 3kg/ha. 1:4.57 and 1:4.52 and dhatura leaf extract @ 5% 1:3.23 and 1:2.57 during both years.
