摘要

Three sprays were carried out and thus, the data obtained revealed that, flonicamid 50 WG @ 0.4 ml/Lit. was found significantly superior to manage leafhopper and whitefly (2.98 & 2.09 / 3 leaves) population and it was followed by flonicamid 50 WG @ 0.3 ml/Lit. (3.19 & 2.29 / 3 leaves) and imidacloprid 17.8 SL (3.40 & 2.50 / 3 leaves). Similar finding was also reflected on yield and flonicamid 50 WG @ 0.4 ml/Lit. obtained highest (103.07 q/ha) yield among all the treatments and it was followed by flonicamid 50 WG @ 0.3 ml/Lit. (98.93 q/ha). None of the insecticides had adverse effect on natural enemies of leafhoppers and whiteflies in okra ecosystem.
