Abstract:
The present investigation was carried out in randomized block design (RBD) during Kharif 2021 at the experimental field, BRDPG College, Deoria, Uttar Pradesh. Six treatments including an untreated check were evaluated against pests of okra in randomized block design. Overall efficacy of the insecticides against sucking insect pests in current investigation revealed that beta-cyfluthrin 8.49% + imidacloprid 19.81% @1 ml/liter and thiamethoxam 25 WG @ 0.5 g/liter was found most effective. The treatment lambda-cyhalothrin 4.6% + chlorantraniliprole 9.3% @1 ml and fipronil 5% SC @ 2 ml/liter were found next in order of effectiveness, while neem gold 2% @ 2 ml/liter and neem oil 3% @3 mll/liter were comparatively least effective in population reduction of sucking insect pests.
