Inside a squat, brick building set among roughly 800 acres of row crops, a mix of scientists, local growers and Arkansas Plant Board members prepare to get a look at an all-too-familiar problem.

They'll be touring the University of Arkansas System Division of Agriculture's Northeast Research and Extension Center in Keiser, near the banks of the Mississippi River. Plant Board Chair Greg Hay prepares the group for what they're about to see.

Following months of consideration, the Arkansas Plant Board has voted to loosen its ban on the controversial herbicide dicamba.

In an eight-hour meeting Wednesday, the board voted to move the cutoff date for spraying the herbicide from April 15 to May 25. A group of farmers had been seeking to push the date back to as late as June 15, but at the outset of Wednesday's meeting board members had been considering May 20 as a compromise.
