Field experiment was conducted to manage the sedge and broad leaf weeds in lawn during November to December 2013 to February to March 2014. Experimental plot was red sandy loam soil with pH 6.50.The experimental plot consisted of bermuda grass Cynodon dactylon which was established through turfing. The experimental plot was laid out in a randomized complete block design (RCBD) having 17 treatments with three replications. Herbicide treatments include 2, 4-D sodium salt 80 WP at (2, 3 and 4g/lit of water), 2, 4-D dimethyl amine salt 58% EC at (5, 7.5 and 10 ml/lit of water), carfentrozone ethyl 40 DF at (0.25, 0.5 and 1 g/lit of water), fluroxypyr meptyl 48% EC at (1.5, 3 and 6 ml/lit of water) and chlorimuron methyl + metasulfuron methyl at (0.3, 0.4 and 0.5 g/lit of water). Hand weeding was done at every 20 days interval at 20 days after application of herbicides and also maintained one unweeded control in during November to December and February to March. The phytotoxic symptoms were observed only fluroxypyr meptyl 48% EC applied at 6 ml/lit of water at 3, 7, 10, 15 and 25 days after application of herbicides (DAAH) but it recovered at later stages. However, the other herbicides did not cause any phytotoxic effect on C. dactylon.
