Abstract:
Bio-efficacy of newer insecticides were assessed against pod borer, Helicoverpa armigera Hubner on pigeonpea during Kharif, 2020. The results revealed that all the treatments were significantly superior in reducing the pest infestation. However, Chlorantraniliprole 18.5SC at 150 ml/ha caused significantly minimum larval population recorded the lowest flower, pod, and grain damage, and significantly found maximum grain yield. Indoxacarb 14.5 SC at 500 ml/ha and Flubendiamide 480 SC at 100 ml/ha were found to be the next best effective treatment. Whereas, Novaluran 10 EC at 500 ml/ha and Monocrotophos 36 SL 500 ml/ha (Farmer’s practices) were observed least effective treatments against the pest. The yield increased varied from 22.85 to 90.81 percent. The highest (1:7:51) ICBR was also recorded Chlorantraniliprole 18.5 SC at 150 ml/ha followed by Indoxacarb 14.5 SC at 500 ml/ha (1:5.98), Spinosad 45 SC at 125 ml/ha (1:4.94) and Emamectin benzoate 5 SG at 125 gm/ha (1:4.55).
