Abstract

An experiment was conducted during rainy (kharif) season of 2021 at the Agricultural Farm of Banaras Hindu University, Varanasi, Uttar Pradesh for evaluating the efficacy of pre-mix herbicide combinations applied as post emergence in managing weeds in transplanted rice. We assessed 9 different weed management treatments, including sole herbicide and pre-mix combinations and hand weeding in randomized block design. Results showed that herbicide combinations such as triafamone + ethoxysulfuron and bispyribac sodium + pyrazosulfuron effectively reduced weed density and biomass, improving crop growth attributes and ultimately yield. The study highlights the importance of using herbicide combinations for effective weed management in puddle-transplanted rice cultivation.
