Abstract:Background: Pigeonpea is one of the most widely grown pulse crop in India, and farmers should use recommended pesticides to harvest good yield instead of using ineffective and unknown agrochemicals.
Methods: A field trial was conducted at RLBCAU, Jhansi, (India), to study efficacy of Beauveria bassiana, chlorantraniliprole, cypermethrin, emmamectin benzoate, indoxacarb, profenophose, quinalphos, and spinosad against leaf webber, (Maruca vitrata Geyer), pod borer, (Helicoverpa armigera), and pod fly, (Melanagromyza obtuse) affecting pigeonpea crop during Kharif season 2020.
Result: Spinosad had the most extended residual effect on pigeonpea against all the insects, thus been able to save more than 90% of the pod and grain from insect damage, as well as reduce larval populations by 90%. The spinosad treated plots provided the higher benefit cost ratio and grain yield.
