Even before Roundup Ready crops Arkansas farmers were moving away from residual herbicides to more total postemergence weed control programs. The big reason was due to the erratic nature of residual herbicides.

At a recent meeting at the Arkansas State Plant Board, new dicamba- and 2,4-D-tolerant crops were discussed. There were presentations by several university weed scientists and representatives of the respective companies.
