Boehmeria nivea, Ramie, Fiber yield, Imperata cylindrica, Quizalofop-ethyl, Weed

Imperata cylindrica was the dominant grass weed (42-46%) followed by Cynodon dactylon (10%) and Cyperus rotundus (8-12%). Weed infestation throughout growing season of ramie reduced the fibre yield up to 51%. Significant reduction in weed density and dry weight was recorded in both quizalofop-ethyl at 40 g/ha and quizalofop-ethyl at 60 g/ha with weed control efficiency of 72-77% and weed index of 11-15%. The highest fibre yield was recorded in weed free treatment (470-504 kg/ha/cut) which was statistically at par with that of quizalofop-ethyl at 40 g/ha and quizalofop-ethyl at 60 ml/ha treatments (400-447 kg/ha/cut), respectively. Significant reduction of plant height of ramie was observed in ethoxysulfuron at 20 g/ha at initial growth stage. Quizalofop-ethyl at 40 g/ha or quizalofop-ethyl at 60 g/ha followed by one hand weeding may be applied for effective weed control in ramie.
