Fifteen treatments with different doses and concentrations of pyroxsulam (12, 15, 18 and 30 g/ha of 3.0% and 3.6% OD both) along with 2,4-D ethyl ester 190 g/ha and aminopyralid 7.5 g/ha were taken in the experimental plot. Treatments having sulfosulfuron 25 g/ha, clodinafop 60 g/ha and isoproturon 1000 g/ha, weed free and weedy plot were also included as standard check. Application of pyroxsulam at 12 and 15 g, recorded significantly lower weed density of Phalaris minor at their lower concentration (3.0% OD) as compared to their higher concentration (3.6% O.D.). However, pyroxsulam at their higher doses (18 and 30 g) recorded similar density of Phalaris minor at both the concentrations at 30 days after herbicide application
