Abstract: (Triticum aestivum L.) is the world’s most widely cultivated and leading staple food. But their production is continuously decreased due to infestation of grassy and broadleaf weeds. Chenopodium album is most dominant broadleaf weed of wheat and other Rabi crops. Which limit the production of Rabi crops. Therefore, there is need to know about the current status of herbicide resistance/poor efficacy of different herbicides against C. album. The present investigation was conducted during the Rabi season of 2017-18 in the screen house of Department of Agronomy Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana). Pot experiment was conducted in completely randomized design, replicated thrice using different herbicides namely Accord Plus and Lanfida applied at three doses (0.5X, X and 2.0X) in the experiment as post-emergence. Untreated pots were maintained as control for comparison. The results in general indicated that Chenopodium populations have poor efficacy was observed with Lanfida; however application of Accord Plus recorded complete control. Higher value of plant height, chlorophyll fluorescence, fresh weight and dry weight and lower value of EC was observed in the herbicidal treatments showing poor efficacy against the test populations. Accord Plus post-emergence (POE) application of other herbicides has already been recommended and promoted for the management of Chenopodium populations.
