A field experiment entitled "Integrated weed management in isabgol (Plantago ovata Forsk.)". was carried out during rabi season of 2019-20 at the Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The experiment comprising nine treatments was laid out in randomized block design with three replications. The results revealed that next to the weed free treatment, significantly higher values of growth parameters viz., plant height and plant spread, yield and yield attributes viz., seed yield plant-1 and stover yield plant-1, seed yield, stover yield, test weight and harvest index were recorded with Pendimethalin 900 g/ha as pre-emergence + Quizalofop ethyl 50 g/ha applied as a post-emergence at 35-40 DAS followed by the treatment Pendimethalin 900 g/ha as pre-emergence + Oxadiargyl 80 g/ha applied as a post-emergence at 35-40 DAS. Besides, weed free condition, application of Pendimethalin 900 g/ha as pre-emergence + Quizalofop ethyl 50 g/ha post-emergence at 35-40 DAS followed by the treatment Pendimethalin 900 g/ha as pre-emergence + Oxadiargyl 80 g/ha applied as a post-emergence at 35-40 DAS were found more effective in reducing the weed population up to harvest and resulted in minimum dry weight of weeds, besides lower weed index and higher weed control efficiency and herbicidal efficiency index.
