Response of Xtend Cotton to Low Rates of 2,4-D

Field study was conducted in 2019 at the Delta Research and Extension Center, in Stoneville, Mississippi, to evaluate cotton (Xtend technology) injury at various low rates of 2,4-D (1/16X, 1/32X, and 1/64X) and assess which crop growth stage is more sensitive than the others. All applications were made at three cotton growth stages: 3- to 4-leaf, square, and at flowering. 2,4-D (1X) rate is 32 fl oz/A.
