Abstract
The purpose of the experiment was to compare the effectiveness of four newer insecticides: rynaxpyr, spinosad, indoxacarb, and emamectin benzoate with bio-based insecticides such as Bacillus thuringiensis, HaNPV, biodynamics and waste decomposer along with control (untreated) for the management of gram pod borer, it’s a major insect pest problem of chickpea crop throughout India as well as in Punjab. The result revealed that all the treatments like insecticides and bio-based were effective as compared to control (2.66 larvae per five plants) and percent pod damage (23.05%). Among the all treatment T2 application of spinosad was proved as a best treatments for the management of gram pod borer larvae (0.91 larvae per five plants) and pod damage percentage (9.25%) and yield (23.8 qn/ ha) over the performance of control (12.5 qn/ha) in treated plot followed by the T3 rynaxpyr (1.03 larvae per five plants), (10.35%) and yield (21.5 qn/ha) performance over control followed by the T1 emamectin benzoate and T4 indoxacarb after these newer insecticide bio-based insecticides T5 Waste decomposer was found effective with (1.30 larvae per five plants), percent pod damage (12.04%) and (17.90 qn /ha) which is followed by the T6 B. thuringiensis, T5 HaNPV, T9 NSKE respectively and T7 biodynamics spray was least effective than other treatments (1.74 larvae per five plant), (12.04 larvae/five plants) and yield (15.5 qn/ha) but effective as compared to the untreated plot. Where spinosad was most effective to manage the H. armigera in chickpea crop.
