Evaluation of different integrated pest management modules against lentil aphid (Aphis craccivora) in lower gangetic plains of Eastern India

The current research work was proposed to assess the feasibility and economic viability of three integrated pest management (IPM) modules including farmers' practices against major lentil pest, lentil aphid (A. craccivora). The IPM modules comprised of different strategies including seed treatment, use of bio-rational and new generation insecticides with novel mode of action. Module 2 i.e. seed treatment with Imidacloprid 600 FS and Carbendazim 50 WP (@ 3 ml + 2 g/kg of seed), Rhizobium treatment + PSB + PGPR, application of NSKE 5% at 40 days after sowing (DAS) and spraying with Chlorantraniliprole 18.5 SC @ 20 g a.i./ha at 50% flowering stage was found to be superior to other modules in respect of managing aphid population and highest yield and net return as well as highest benefit cost ratio of 3.17. Module 4 i.e. farmers' practice was the least effective in terms of reduction in pest incidence and yield.
