Evaluation of New Molecules in Ipm Modules Against Helicoverpa Armigera (HüBner) in Chick Pea

Field trial was laid during rabi seasons on various IPM modules evaluated on cv. ‘JG-315’ of Chick pea. Module M₅ (pheromone traps @ 20/ha, bird perch @ 40/ha, chlorantriniliprole @ 0.15 lit/ha & water spray) followed by M₄ (pheromone traps @ 20/ha, bird perch @ 40/ha, emamectine benzoate 5 SG @ 0.15 kg/ha and HaNPV@ 400 LE/ha + Teepol + sugar) and M₃ (pheromone traps @ 20/ha,bird perch @ 40/ha,flubendiamide 39.35 SC 0.08 lit/ha and HaNPV@ 400 LE/ha + Teepol + sugar) were found effective to reducing the population of H. armigera. The highest yield (1592 kg/ha in 2009 & 1607 kg/ha in 2010) was obtained from M₅ followed by M₄ (1545 kg/ha in 2009 & 1558 kg/ha in 2010) in comparison to control and other modules including farmer’s practice. The highest B: C ratio were obtained from M₅ (1:3.47) followed by M₃ (1:3.35), M₄ (1:3.18), M₁ (1:2.52), M₂ (1:2.28) and M₆-farmer practice (1:1.89) and the trend was almost similar in the succeeding year. Module M_5, was proved superior to other modules in respect of managing the pest infestation and B:C ratio.
