Abstract

Experiments on evaluation of blackgram (urdbean) Integrated Pest Management (IPM) module in comparison with the farmers’ practice were conducted at National Pulses Research Centre (NPRC), Tamil Nadu Agricultural University, Vamban, as well as in farmer's holdings with the variety Vamban 3 during kharif 2002 and 2003. Adoption of IPM module consisting of the components viz., seed treatment, erection of bird perches, installation of pheromone traps against Spodoptera litura and Helicoverpa armigera, use of bio-rational pesticides viz., Neem Seed Kernel Extract, S1 NPV/Ha NPV, mechanical management and need based application of insecticides registered reduced pod borer damage (4.2–10.8%), and pod bug damage (2.7–5.8%) as against the farmers’ practice viz., dusting with lindane 1.3 D @ 25 kg/ha at peak flowering, which registered higher pod borer damage (5.8–13.8%), and pod bug damage (3.8–7.8%). The grain yield (528–852 kg/ha.) and Benefit: Cost (1.37–2.21) were also higher in IPM plots compared to farmers’ practice.
