Widespread resistance in Phalaris minor is a major challenge for sustainable productivity. Recent increases in the development of herbicide resistance in Phalaris minor worldwide demand a high up strategies to control this weed. Herbicide-resistant weeds are a constraint to weed management. The use of potential management strategies is crucial in assuring sustainable production. A pot-culture experiment was conducted during the winter season of 2017-18 with the objective to evaluate the herbicidal efficacy for management of isoproturon-resistant Phalaris minor. Post-emergence herbicides used in this study were clodinafop –propargyl, metribuzin, sulfosulfuron, pinoxaden and Halauxifen methyl +Pyroxsulam. Increased doses (up to 1.5X &2.0X) of herbicide provided effective control of P. minor. However, application of recommended dose (1.0X) of metribuzin provides a satisfactory control of P. minor. These findings suggest that post-emergence herbicide controls resistant P. minor and delay further herbicide resistance in this weed.
