 ABSTRACT

A pot experiment to evaluate the efficacy of different doses of post-emergence herbicide isoproturon against broadleaf weed Chenopodium spp. was conducted during Rabi season of 2017-18 in the screen house at Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana) in wheat crop. It is applied at three doses (0.5X, X and 2.0X) in experiment under Completely Randomised Design (CRD) replicated thrice with six populations of Chenopodium spp. named as Siswal 1, Siswal 2, Saharwa, Charkhi Dadri, H.A.U. 1 and H.A.U. 2 populations collected from farmers fields of Haryana. Untreated pots were maintained as control for comparison. In observations, plant height, chlorophyll fluorescence, electrical conductivity (EC), percent control, fresh weight and dry weight were observed. Results revealed that isoproturon provided 100 per cent control to all populations even at half of the recommended dose of this herbicide. This is the key finding of this study because intervention with post-emergence isoproturon could resolve the problem of resistant Chenopodium spp. being faced by the farmers.

Key words: Chlorophyll fluorescence, Efficacy, Isoproturon, Chenopodium spp., Population.
