Abstract

The research was conducted on okra crop to check the efficacy of some insecticides and their combinations against okra shoot and fruit borer, Earias vittella (Fab.). The study was carried out during kharif 2023 at Central Research Farm of Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (U.P.) with eight treatments including untreated check which were replicated thrice. All the treatments were found to be superior over untreated control, neem oil 3%, spinosad 45 SC, cypermethrin 25 EC, profenophos 50 EC, spinosad 45SC + neem oil 3%, cypermethrin 25EC + neem oil 3%, profenofos 50 EC + cypermethrin 25 EC were tested to compare the efficacy against Earias vitella and their influences on yield of okra. Here the best and the most economic treatment was profenofos 50 EC + cypermethrin 25 EC followed by cypermethrin 25EC + neem oil 3%, spinosad 45SC + neem oil 3%, spinosad 45 SC, cypermethrin 25 EC, profenophos 50 EC and the least effective treatment was neem oil 3%. The highest yield among the treatments was noticed in profenofos 50 EC + cypermethrin 25 EC (140quintal/hac.) and the lowest in neem oil 3% (75quintal/hac.) with cost benefit ratio 1:4.7 and 1:2.0, respectively.
