Abstract: A field experiment was conducted at Agricultural College and Research Institute, Coimbatore during December, 2018 to March, 2019 to study the effect of chemical weed management practices on economics of irrigated sesame. The field experiment was laid out in randomized block design with eleven treatments and replicated thrice. Total cost of cultivation,gross return, net return and benefit cost ratio were computedfor each treatment.Cost of production of sesame crop was highly influenced by the weed management options due to high infestation of weeds and increased labour cost. On the basis of field experimentation, it can be concluded that, integrating herbicide and hand weeding provided the highest net profit due to increased yield at a relatively low cost. Results revealed that pre-emergence application of pendimethalin @ 750g/ha with one hand weeding at 30 DAS recorded significantly higher gross and net return, compared to other treatments which also resulted to high benefit cost ratio. In addition to that, PE pendimethalin 38.7 CS @ 0.65 kg a.i./ha+ HW at 30 DAS (T2), EPoE imazythapyr 35 a.e. + Imazamox 35 a.e. @ 30 g a.e./ha + HW at 40 DAS (T9) and PE oxyfluorfen 23.5 EC @ 200 g a.i./ha+ HW at 30DAS (T3) recorded higher net return and benefit cost ratio than twice hand weeding even though lower yield is recorded compared to twice hand weeding.
