PRE herbicides were applied using 145 L ha−1 of water carrier delivered through a CO2-pressurized backpack sprayer with 8002 flat-fan nozzles. POST herbicides were applied 15 to 20 days after planting cotton to 3 to 4 leaves of Palmer amaranth using 145 L ha−1 delivered through an ATV-mounted sprayer with 8002 flat-fan spray nozzles. In 2011, a second POST application glufosinate (0.60 kg ai ha−1) was made to the POST and PRE+POST treatments for added weed control. |
