Broad-leaved weed management in wheat through herbicide mixture in sub-tropical Shivalik Himalayan foothills

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.
