Response of purple nutsedge to glyphosae

Response of purple nutsedge to glyphosae

Proceedings 28th Annual Meeting Southern Weed Science Society: 146

Purple nutsedge clones were well controlled with glyphosate at 1.5 and 3 lb/acre applied from 3 weeks after initial foliar emergence. C. rotundus was susceptible to glyphosate when applied 7 weeks after foliar emergence. Established stands of C. rotundus treated in June 1973 with glyphosate at 0.38, 0.75, 1.5 and 3 lb/acre showed the greatest response to the herbicide (at least 91% control with the higher rates) after 1 month.
