Abstract

A study was conducted at the Agricultural Research Station (UAS, Dharwad), Sankeshwar, Karnataka during Kharif 2022-23 to assess the effectiveness of different insecticides against soybean leaf folder, Omiodes indicata. Among five treatments, lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.4 ml l-1 exhibited the lowest mean population of soybean leaf folder, Omiodes indicata on 5th and 10th day after spray with 2.12 and 0.98 larval population per meter row length, respectively which was followed by emamectin benzoate 5 % SG @ 0.3 g l-1 (3.03 and 1.83 larvae per meter row length).  Lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC was found to be the best effective treatment with 81.97 % reduction over control followed by emamectin benzoate 5 SG (71.61 %). Similar results were obtained with per cent defoliation.
