Abstract

An experiment was carried out to evaluate the IPM components against Helicoverpa armigera at farmer’s fields during 2007-08 crop seasons. The components of IPM package viz, placement of bird perches @ 50/ha to encourage predatory birds, BTk @ 1.0kg/ha and endosulfan 35EC @ 0.07% were undertaken in plots of at least 4000 sq. m. The minimum population of H. armigera was recorded in IPM block (1.38 larvae/mt row length) over farmers practice (3.27 larvae/mt row length). H. armigera incidence was reduced 57.80 per cent in recommended practice. The grain yield was increased 26.24 per cent in recommended practices over farmers practice and also Rs 7245/- per ha additional net return was obtained.
