A field experiment was conducted in a farmer’s field near Chidambaram to evaluate some pesticides against key cabbage insect pests during kharif 2018 and summer 2019. The results revealed that emamectin benzoate 5SG, spinosad 45SC, flubendiamide 39.35SC, indoxacarb 14.5SC, chlorfenapyr 10SC and lambda cyhalothrin 5EC effectively reduced the incidence of Spodoptera litura (L.) and Trichoplusia orichalcea (F.) Maximum reduction was accomplished with flubendiamide and spinosad. Occurrence of natural enemies when evaluated did not reveal statistically significant differences. Maximum yield was obtained with flubendiamide (24.08, 25.15 t/ha) followed by spinosad (23.41, 23.19 t/ ha).
