Abstract
Evolution of multiple herbicide resistance in Phalaris minor in wheat has resulted from the repeated use of herbicides with a similar mode of action which could threaten the sustainability of the rice-wheat cropping system in North-West India. In this context, field studies were conducted at Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during 2011–12, 2012–13 and 2013–14 in randomized block design replicated four times and at farmer's field during 2016–17 and 2017–18 with the objective to evaluate the efficacy of herbicide with alternative mechanism of action for the control of resistant P. minor in wheat. The treatments included pyroxasulfone 85, 102, 127.5 g/ha, pendimethalin 750 g/ha as pre-emergence (PE), sulfosulfuron 25 g/ha, clodinafop 60 g/ha as postemergence (PoE) and unsprayed control. However, the treatments during 2013–14 included pyroxasulfone 85, 102, 127.5 g/ha, pendimethalin 750 g/ha and unsprayed control with pendimethalin 1125 g/ha as PE at farmers’ field instead of pendimethalin 750 g/ha. The results indicated that pyroxasulfone at 127.5 g/ha recorded effective control of P. minor and its biomass and gave the highest wheat grain yield (4.87, 4.80 and 5.43 t/ha) during 2011–12, 2012–13 and 2013–14, respectively At farmer's field, pyroxasulfone 127.5 g/ha has been found effective against the resistant populations of Phalaris with 5.37 and 5.42 t/ha grain yield. The current study demonstrated that PE application of pyroxasulfone at 127.5 g/ha would be a suitable option for the control of resistant populations of Phalaris in wheat in Punjab.
