Bio-efficacy of emamectin benzoate 5% SG against shoot and fruit borer Earias vitella (Fabricius) on okra

Field experiment was conducted to evaluate and validate the efficacy of some novel insecticides against shoot and fruit borer on okra. Effect of five different doses of Emamectin benzoate 5%SG along with Lambda cyhalothrin 5% EC, Deltamethrin 2.5%EC and Chlorantaniliprole18.5%EC were evaluated. The shoot and fruit borer infestation was recorded. Before each spray as well as 2, 4, 8 and 10 days after each spray. The results clearly indicated that Emamectin benzoate 5%SG at 17.0g a.i/ha were found most effective against shoot and fruit borer with an average reduction of 90.72% in population after three sprays. All treatments gave significantly higher fruits yield of okra over untreated control (3.3t/ha). However, highest yield of okra fruits (8.29t/ha) was obtained from Emamectin benzoate 5%SG at17.0ga.i/ha followed by the treatment Emamectin benzoate 5% SG at 10.25 ga.i/ha yields (8.04t/ha).
