Ignite Rate and Timing In LibertyLink Cotton

LibertyLink cotton was commercialized in 2004 and offers an alternative to Roundup Ready and Roundup Ready Flex for over-the-top weed control in cotton.  The LibertyLink technology allows topical applications of glufosinate from cotton emergence through early bloom.  The technology also serves as a tool in a glyphosate resistance management program.  To date, resistance to glufosinate has not been reported in weeds.  Research was conducted in Stoneville, MS, to (1) evaluate rates of glufosinate in sequential applications in a LibertyLink weed control system with and without a residual herbicide.
