Abstract
A field experiment was conducted at the Agricultural Research farm of Rani Lakshmi Bai Central Agricultural University, Jhansi during the Rabi season 2021-22 to find out the efficacy of different IPM modules on the larval population of Helicoverpa armigera (Hubner) in chickpea. Among the different tested management modules, module-2 comprising of Spinosad 45% SC (75 g a.i./ha) + Datura leaf extract 25% was found to be most effective in minimizing the larval population (0.69 larvae/ 5 plants) along with that the lowest percent pod damage (6.91%), the highest yield (1.57 t/ha) and the highest net profit were also obtained. However, the highest incremental benefit-cost ratio was recorded in module-1 [NSKE 5% + Marigold (Transplanting 15 days after sowing of chickpea in 3:1)] (6.32: 1) due to less pesticide application and more return obtained from Marigold.
