Online Published on 18 January, 2024. Abstract Weed infestation is one of the major biotic factors limiting wheat production and productivity in absence of weed management practice. In order to control the broad-leaved weed infestation in wheat, the herbicides and their mixtures were tested in a field experiment under All India Coordinated Wheat and Barley Improvement Project, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, India during Rabi (winter) seasons of 2016-17 and 2017-18. Results showed that herbicide mixtures (broad-leaved weed killer) were found better in compared to alone application of broad-leaved weed herbicides. Among herbicide mixtures, application of metsulfuron 4 g/ha + carfentrazone 20 g/ha + surfactant 625 ml/ha resulted in highest growth, yield attributes, grain yield and weed control efficiency and it was followed by 2,4-D E 500 g/ha + carfentrazone 20 g/ha. Hence, the highest net returns ( 72209 and 69762/ha) and B: C (2.81 and 2.60) were recorded by application of metsulfuron 4 g/ha + carfentrazone 20 g/ha+ surfactant 625 ml/ha.Top Keywords 2,4-D, Carfentrazone, Economics, Florasulam, Halauxifen-methyl, Wheat, Weed management.
