Author(s): Prafull Gupt, Navneet Rana and Agale SV

Abstract: Investigation on “Evaluate the bio efficacy of different insecticides against pod borer Helicoverpa armigera in Pigeonpea” was conducted during June 2016 to February 2017, at the Research cum Instructional farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (CG). Management of H. armigera by sequential insecticidal treatments, Treatment 5 with sequential application of Chlorantraniliprole 18.5 SC @ 30g a.i./ha > Chlorantraniliprole 18.5 SC @ 30g a.i./ha > Acetamiprid 20 SP @ 20g a.i./ha maintained its lethal effect with least percent pod damage (15.58%), grain damage (6.41%) showed highest grain yield (1302.08 kg/ha) and net profit over untreated control (Rs.15511.83) which was at par with treatment 6 Chlorantraniliprole 18.5 SC @ 30g a.i./ha > Indoxacarb 15.8 EC @ 73g a.i./ha>Acetamiprid 20 SP @ 20g a.i./ha [(18.23%), (7.21%), (1192.01 kg/ha) and (Rs.11303.30) respectively]. In the untreated control the yield obtain was 856.42 kg /ha which was lowest of all the insecticidal treatments.
