Abstract:

The present study was conducted at the Research cum Instructional Farm, IGKV, Raipur, Chhattisgarh during Kharif season 2013-2014. Economics of eight newer insecticidal molecules, acetamiprid 20SP @ 20g a.i/ha, indoxacarb 14.5SC @ 50g a.i/ha, acephate 75SP @ 750g a.i/ha, spinosad 45SC @ 73g a.i/ha, emamectin benzoate 5WSG @ 9.5g a.i/ha, flubendiamide 20WG @ 50g a.i/ha, rynaxipyr 18.5SC @ 30g a.i/ha and thiamethoxam 25WG @ 75g a.i/ha against pod borer complexof pigeonpeawere evaluatedincluding control as check. Spinosad maintained its lethal effect with least pod damage of 6.00% which was at par with indoxacarb (6.14%), whereas maximum pod damage of 10.03% was recorded with flubendiamide. Pod damage in untreated control was 11.30%.The minimum grain damageof 2.10% was recorded with spinosad and indoxacarb, which were at par with emamectin benzoate (2.63%), whereas the maximum grain damage of 4.26% was recorded in flubendiamide. Grain damage in untreated control was 5.40%.

The highest grain yield (1360.54 Kg/ ha) was recorded in spinosad which was at par with indoxacarb (1207.48 kg/ha) emamectin benzoate (1139.44 kg/ha) and acetamiprid (1122.44 kg/ha), while the lowest grain yield (1037.41 Kg /ha) was recorded in flubendiamide, and the untreated control resulted least (816.32 kg /ha) grain yield.The highest incremental cost-benefit ratio was with spinosad (1:9.48) followed by indoxacarb (1:6.26), emamectin benzoate (1:5.43), acetamiprid (1:5.20), acephate(1:3.18), thiamethoxam (1:3.54) and rynaxipyr (1:2.75) while the lowest incremental cost-benefit ratio was with flubendiamide (1:1.89). Thus application of spinosad, indoxacarb, emamectin benzoate and acetamiprid proved to be the best regarding economic management of pod borers in pigeonpea.
