Abstract:
A field experiment was conducted at Agriculture Experimental Station, Navsari Agricultural University, Paria, Valsad during rabi 2018-19 and 2019-20. The relative efficacy of eleven insecticides, viz., bifenthrin 10 EC (0.01%), imidacloprid 17.8 SL (0.005%), buprofezin 25 SC (0.025%), indoxacarb 14.5 SC (0.00725%), flubendiamide 48 SC (0.015%), chlorantraniliprole 20 SC (0.006%), spinosad 45 SC (0.015%), flonicamid 50 WG (0.0075%), diafenthiuron 50 WP (0.03%), fipronil 5 SC (0.01%) and dinotefuran 20 SG (0.0025%) against pod borer, Helicoverpa armigera Hubner was evaluated. Among the evaluated insecticides, chlorantraniliprole (0.006%), spinosad (0.015%), indoxacarb (0.00725%) and flubendiamide (0.015%) were found more effective against H. armigera. The treatment buprofezin (0.025%) and dinotefuran (0.0025%) found less effective to control the pest. The order of effectiveness of various treatments against H. armigera was found to be chlorantraniliprole (0.006%) ≥ spinosad (0.015%) ≥ indoxacarb (0.00725%) ≥ flubendiamide (0.015%) > bifenthrin (0.01%) ≥ fipronil (0.01%) ≥ diafenthiuron (0.03%) > imidacloprid (0.005%) ≥ flonicamid (0.0075%) ≥ buprofezin (0.025%) ≥ dinotefuran (0.0025%) > control.
