 ABSTRACT

The present study was carried out during Rabi season of 2017-18 at Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana) to evaluate the efficacy of metribuzin as a pre emergence intervention against Rumex spp. in wheat crop. It was applied at three doses (0.5X, X and 2.0X ) in pot experiment under Completely Randomised Design (CRD) replicated thrice with four populations of Rumex spp. named as HHH (HAU Hisar), UPH (Ujha, Panipat), JHH (Jind) and JJR (Jhajjar) collected from farmers fields of Haryana. One unsprayed control was also kept for each population for comparison. In observations, plant height, chlorophyll fluorescence, electrical conductivity (EC), percent control, fresh weight and dry weight were recorded. Metribuzin as pre-emergence intervention provided 100 per cent control of all biotypes. No emergence was found in pots sprayed with metribuzin even at half of the recommended dose of this herbicide. This is the key finding of this study because pre-emergence intervention with metribuzin could resolve the problem of resistant Rumex biotypes being faced by the farmers.
