Cost Effective Analysis of Fall Armyworm (Lepidoptera: Noctuidae) on Maize at Allahabad

During Kharif 2022, an experiment was conducted to evaluate the cost benefit ratio by using different insecticidal application viz., Indoxacarb 14.5 SC @ 425ml/ha, Spinetoram 11.7 SC @ 250ml/ha, Azadirachtin 0.15% @ 5ml/ha, Nisco sixer plus @ 500 ml/ha, lambda cyhalothrin 5 EC @ 320ml/ha, cypermethrin 25 EC @ 1lit/ha, fipronil 0.6% G @ 60 g/ha and untreated control against fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), on maize with three replications. Results revealed that highest grain yield was recorded in (T2) Spinetoram 11.7 SC (64.58 q/ha) followed by (T1) Indoxacarb 14.5 SC (60.49 q/ha), (T5) Lambda cyhalothrin 5 EC (58.34 q/ha). Insecticidal treatment with (T2) Spinetoram 11.7 SC (1:2.31) had the highest cost benefit ratio, followed by (T1) Indoxacarb 14.5 SC (1:2.11), (T5) Lambda cyhalothrin (1:2.10), (T6) Cypermethrin 25% EC (1:2.04), (T7) Fipronil 0.6 % G (1:2.03), (T4) Nisco sixer plus (1:1.99), (T3) Azadirachtin 0.15 % (1:1.97) over untreated control (1:1.91). End of the experiment it reported that spinetoram is best for crop compare to other chemicals.
