Abstract
Field trails on effectiveness of different IPM modules, including chemicals and cultural methods, against fall armyworm, Spodoptera frugiperda (J.E. Smith) infesting maize, conducted at University Research Farm, BCKV, Gayeshpur, West Bengal during 2021 and 2022, revealed significant reduction in larval population (60.75-56.12 per cent and 59.38-59.5 per cent) together with increased yield (57.33-50.67 q ha-1 and 58.17-51.50 q ha-1) over control IPM in module comprising hybrid napier grass as border + chlorantraniliprole (10%) + lamdacyhalothrin (5% ZC) @ 45g a.i ha-1 at 3 weeks after sowing + indoxacarb 14.5 per cent SC @ 50g a.i ha-1 5 weeks after sowing +lamdacyhalothrin 5 per cent EC @ 25g a.i ha-1, 7 weeks after sowing. The module 6 comprising with spinetoram 11.7 per cent SC (30g a.i ha-1) at 3 weeks after sowing and chlorantraniliprole 18.5SC (50g a.i ha-1) at 5 weeks after sowing and emamectin benzoate 5 per cent SG (10g a.i ha-1) at 7 weeks after sowing both the years of experimentation after sowing was found on par in respective parameters during 2021 and 2021, respectively. Two other modules, one with intercropping of coriander + spinosad 45 per cent SC @ 60g ai ha-1 at 3 weeks after sowing + azadirachtin 10,000ppm @ 5g a.i ha-1 at 5 weeks after sowing + chlorantraniliprole 18.5 per cent SC @ 50g a.i ha-1 at 7 weeks after sowing and the other comprising of chlorantraniliprole 18.5SC @ 50g a.i ha-1 three applications at 3, 5 and 7 WAS, were moderately effective in the management S. trugiperda.
