Evaluation of eco-friendly approaches for the management of pod borer complex of pigeonpea [Cajanus cajan (L.) Millsp.]

Md. Abbas Ahmad

The field experiment conducted to evaluate the relative efficacy of different biopesticides against gram pod borer complex Helicoverpa armigera (Hübner) and pod fly, Melanogromyza obtusa (Malloch) infesting Pigenopea during Kharif season 2018-19. The population was recorded at different days after spraying of insecticides and it was found that the number of larvae varied non-significantly different from the control in both spray application. The pod borer H. armigera was found lowest in Chlorantraniliprole 18.5 SC @ 30 g a.i/ha (6.25%), followed by Azadirachtin 1500 ppm @ 5.0 ml/l (7.33%) and Bt. kurastaki @ 1.0 g/l (9.33%) as compared to control (13.89%). Grain damage varied from minimum (8.42%) due to pod fly, M. obtusa and pod borer, H. armigera (3.35%) Chlorantraniliprole 18.5 SC @ 30 g a.i/ha followed by Azadirachtin 1500 ppm @ 5.0 ml/l (14.25%) as compared to (27.63%) due to pod fly, M. obtusa and (13.89%) pod borer, H. armigera in untreated control.
