Field experiments were conducted on groundnut for white grub Holotrichia consanguinea Blachard management using different IPM components in Gujarat during kharif 2018 and 2019. Two different eco-friendly modules were evaluated and compare with farmers practices. In Module I included on set of monsoon, spraying of chlorpyrifos 20 EC @ 0.04% on surrounding trees, seed treatment of chlorpyrifos 20 EC @ 20 ml/kg, Placement of aggregation pheromone on host tree (5 block/tree), Soil application of Beauveria bassiana @ 5 kg ha-1 (Min. 2 x 106 CFU/g) + castor cake (250 kg ha-1) before sowing, Application of B. bassiana @ 5 kg ha-1 in plant row with FYM (250 kg ha-1) after 30 days of germination. While Module II used Metarhizium anisopliae instead of B. bassiana. While in farmers practices included application of chlorpyriphos 10 G @ 10 kg ha-1 with urea at initiation of pest attack. Among the evaluated two ecofriendly module and farmers practices the lowest per cent plant mortality (3.03 %) and 0.56 grub/m2 was recorded in Module II. The highest pod and halum yield 2180 and 3942 kg ha-1, yield increase over control 31.00 and 39.37 %, avoidable loss 23.67 and 28.25% was recorded in module II. The maximum (32474 Rs/ha) net realization was found in the treatment of Module II. Looking to the NICBR, the highest (1:5.35) return was obtained with the treatment of Module II followed by Module I (1:2.93).
