abstract
The present field experiment were conducted to evaluate “Bio-efficacy of different insecticides against gram pod borer (Helicoverpa armigera) on groundnut” under field condition during Kharif season of 2019 at research farm of Oilseed Research Station, Latur, Maharashtra, India. The observations on total number of gram pod borer larvae were recorded on top, middle and bottom leaves of five randomly selected plants from each treatment at one day before and 3, 7, and 14 days after first and second application of insecticides. The treatments of different insecticides viz., Chlorantranilliprole 0.0185 percent, Indoxacarb 0.01 percent, Emamectin benzoate 0.002 percent, Cypermethrin 0.002 percent, Profenophos 0.1 percent and Quinalphos 0.005 percent were evaluated against gram pod borer (Helicoverpa armigera H.) revealed that among all the insecticides chlorantranilliprole 0.0185 percent was found most effective for managing gram pod borer larvae population followed by indoxacarb 0.01 percent, emamectin benzoate 0.002 percent, cypermethrin 0.002 percent, profenophos 0.1 percent and quinalphos 0.005 percent Significantly higher seed yield (3286 kg/ha) of groundnut was recorded in treatment chlorantranilliprole 0.0185 percent however, it was found at par with treatment Indoxacarb 0.01 percent (3133 kg/ha). The highest ICBR (1:5.02) was recorded with treatment chlorantranilliprole 0.0185 percent which was followed by Indoxacarb 0.01 percent (1:4.91).
