Abstract:
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).
