Abstract: A field experiment was conducted during Kharif 2016-17 using variety PKV TARA with eight treatments against the pod borer complex of Pigeon pea (Cajanus cajan L.)
The lowest population of H. armigera i.e 0.00 L/plant (100.00% larval reduction) was noticed in Flubendiamide 20 WDG and was most effective treatment and was found at par with Chlorantraniliprole 18.5 SC with 0.04 L/plant (90.47% larval reduction) followed by Spinosad 45 SC with 0.05 L/plant (88.63% larval reduction), Emamectin benzoate 5 SG with 0.05 L/plant (81.57% larval reduction), Indoxacarb 14.5 SC with 0.10 L/plant (75.00% larval reduction), Neem oil 2% with 0.13 L/plant (67.50% larval reduction) and (T1) i.e NSE 5% which was least effective than chemicals and recorded 0.13 L/plant (67.50% larval reduction) whereas highest population of H. armigera i.e 0.50 L/plant was recorded in control (water spray).
All the treatments recorded significantly higher yield over control. It was highest in Flubendiamide 20 WDG (15.66 q/h) with highest incremental cost benefit ratio of 6.32 over the control.
