Evaluation of different insecticides at different days after crossing ETL of moth trap catches on incidence of pink bollworm Pectinophora gossypiella on Bt cotton

DU Gosavi, BV Bhede and SS Ajabe

The field experiment was conducted in Kharif season of 2018 at Department of Agricultural Entomology, V.N.M.K.V. Parbhani (M.S.), India to evaluate different insecticides on different days after pheromone trap (gossyplure) catches (after crossing ETL of 8 moths/ trap/ night.) for the management of pink bollworm on Bt cotton. The experiment was laid out in Split plot Design with three replications. The results revealed that the proper period for spraying was 2nd (T1) and (T2) 6th day after crossing ETL of moths trapped in pheromone traps. It was followed by 10th (T3) and 14th (T4) day after crossing ETL. The most effective insecticide against pink bollworm was lambda-cyhalothrin 5 EC and followed by profenofos 40 + cypermethrin 4 EC, profenofos 50 EC and chlorantraniliprole 18.5 SC. The interaction results indicated that spraying of lamda-cyhalothrin 5 EC on 2nd and 6th day after crossing ETL of moth trap catches in pheromone trap showed most effective management of pink bollworm on Bt cotton.
