A field experiments with the objective to determine the performance evaluation of Oxadiargyl for effective weed management in sunflower was conducted under irrigated condition. The experiment was laid out in randomized block design consisting of nine treatments and replicated thrice. Weed free environment produced higher growth and yield parameters, however it’s on par with the other treatments T2 and T3 which are having combination of herbicide followed by hand weeding. Pre emergence application of Oxadiargyl @ 125g ai/ha fb hand weeding gave excellent control of all the weeds at all the stages of the crop and it recorded higher weed control efficiency and the lowest weed index. Highest net returns of Rs. 26,151/ha and benefit cost ratio of 1.47 was observed in Pre emergence application of Oxadiargyl @ 125g ai/ha fb hand weeding at 30 DAS.
