A field experiment was conducted to evaluate the effect of sequential application of herbicides on weed density, weed dry weight and yield of winter irrigated cotton in 2019-2020 at Agricultural College and Research Institute, Madurai, Tamil Nadu. In cotton field, lesser number of weeds m-2 and weed dry weight m-2 were observed in weed free check and was followed by pre-emergence(PE) application of pendimethalin at 1.0 kg ha-1 at 3 DAS followed by one hand weeding at 30 DAS followed by pendimethalin 1.0 kg ha-1 (T6) (Lay by application). The highest seed cotton yield was obtained in weed free check (T7) which was statistically on par with treatment pre-emergence application of pendimethalin at 1.0 kg ha-1 at 3 DAS followed by one hand weeding at 30 DAS followed by pendimethalin 1.0 kg ha-1 (T6) (Lay by application). During the experimentation the highest B:C ratio was obtained in pre-emergence application of pendimethalin at 1.0 kg ha-1 at 3 DAS followed by one hand weeding at 30 DAS followed by pendimethalin 1.0 kg ha-1 (T6)(Lay by application).
