M.Z.H. PRODHAN, M. ALTAF HOSSAIN, HOSNA KOHINUR, M.K.U. MOLLAH3 AND M.H. RAHMANAn experiment was conducted at the field of Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Ishurdi, Pabna, during March to June 2008 to develop integrated management approaches against insect pest complex of mungbean. The management approaches tested in the study were T1= Seed treatment with Imidachlorpid (5g/kg seeds) + Poultry manure (3t/ha) + Sequential release of bio-control agent (Trichograma chilonis + Bracon habetor) + Detergent @ 2g/l of water, T2 =Seed treatment with Imidachlorpid (5g/kg seeds) + Poultry manure (3t/ha) + Sequential release of biocontrol agent (Trichograma chilonis + Bracon habetor) +Neem seed karnel extract @ 50gm/lof water, T3 = Seed treatment with Imidachlorpid (5g/kg seeds) + Poultry manure (3t/ha) + Spray with Quinalphos @ 1ml / l of water and T4 = Untreated control. All the treatments significantly reduced insect’s infestation (except thrips) and produced higher yield compared to control. It was found that the highest yield was obtained from the treatment T3 (1316 kg/ha) which was statistically similar to T2 (1316 kg/ha) and T1 (1283 kg/ha). In case of Benefit Cost Ratio (BCR), the highest value was obtained from the treatment T3 (1.84), which was followed by T1 (1.55) and T2 (1.31).Download
