In 2-year field trial conducted at winter season at farmers field. Eleven treatments were assessed for the effectiveness of insecticides and plant extracts (oils) against the gram bean borer. There were 1.08 to 14.30 larvae per 5 plants of H. armigera at the start of experiment. Emamectin benzoate 5 SG @ 11 g active ingradient per hectare (T3) recorded the lowest bean borer population (1.08 larvae/5 plants), and it outperformed the other treatments. Chlorantraniliprole 200 SC @ 25 g active ingradient per hectare (T2), emamectin benzoate 5 SG @ 8.25 g active ingradient per hectare + nirgundi oil @ 6% (T11), emamectin benzoate 5 SG @ 8.25 g active ingradient per hectare + pongamia oil @ 2.5% (T10), chlorantraniliprole 200 SC @ 18.75 g active ingradient per hectare + nirgundi oil @ 6% (T9), and chlorantraniliprole 200 SC @ 18.75 g active ingradient per hectare + pongamia oil @ 2.5% (T8) also demonstrated a significant decrease in bean borer populations with 1.12, 1.17, 1.21, 1.26, and 1.35 larvae/5 plants, respectively. The untreated control showed highest population of H. armigera
