Field experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Bawal (Rewari), Haryana during Kharif seasons of 2011 and 2012. Fifteen treatments including three insecticides, one fungicide, three antagonists, one amendment and one neem formulation were evaluated in sole and combination treatments as seed dresser whereas chlorpyriphos 20 EC and poultry manure were incorporated in soil to find out effective combination for control of collar rot and white grub of groundnut. Minimum disease incidence 0.3 and 0.7 per cent and white grub infestation 1.2 and 1.5 per cent was recorded during 2011 and 2012 with seed treatment of chlorpyriphos 20 EC @ 25 ml/kg seed + PM 4 @ 10 ml/kg seed + captan 3g/kg seed followed by imidacloprid 17.8 SL @ 7 ml/kg seed and chlorpyriphos 20 EC @ 25 ml /kg seed + Bacillus thuriengensis@ 10 ml/ kg seed + captan 3 g/kg seed. The yield was significantly (at 5% level) low (7.10 q/ha during 2011 and 6.8 q/ha during 2012) in control as compared to chlorpyriphos 20 EC + PM-4 + captan treatment (20.20 q/ha during 2011 and 19.80 q/ha during 2012) which ranked at first place. The seed treated with imidacloprid 17.8 SL 7 ml /kg seed also produced good yield in both the years and was rated as second best treatment followed by chlorpyriphos + Bacillus thurengiensis+ captan. The results obtained herein provide the foundation for an effective and sustainable programme of management for groundnut white grub and collar rot. Integrated approach having chlorpyriphos 20 EC @ 25 ml/ kg seed, Pseudomonas maltophilia(PM4) @ 10 ml/kg seed and captan 3 g/kg seed was found to be most effective for control of collar rot and white grub infestation in ground nut.
