Evaluation of Newer Insecticides on Pod Fly, Melanagromyza obtusa in Pigeon pea (Cajanus cajan)

The present study on the efficacy of newer insecticide molecules on the pod fly infestation and damage revealed that the T₄: Flubendiamide 480 SC @ 30 g a.i. ha⁻¹ and T5: Lufenuron 5.4 EC @ 30 g a.i. ha⁻¹ were significantly superior over other treatments and they were found to be on par with each other and recorded with 4.33 & 4.67 Nos/25 pods, respectively. After two applications of T₄: Flubendiamide 480 SC @ 30 g a.i. ha⁻¹ the podfly damage reduction was up to 81.20% and other treatments reported the damage between 43.82 - 77.93% over untreated check. The highest yield was reported in plots treated with T₄: Flubendiamide 480 SC @ 30 g a.i. ha⁻¹ for its highest grain yield of 711.0 kg/ha with 78.49% increase over untreated check. The other treated plots reported between 459.00 - 613.33 kg of grain yield/ha with 15.23 - 53.89% increase over untreated check. The highest Benefit: Cost ratio was obtained in the plots treated with T₄: Flubendiamide 480 SC @ 30 g a.i. ha⁻¹ (1:1.59) and other treatments reported between 1:1.07–1:1.40.
