The wild battle in Arkansas over dicamba, the controversial and drift-prone herbicide, just got even crazier. Local courts have told some farmers that they don't have to obey a summertime ban on dicamba spraying that the state's agricultural regulators issued last fall. The state has appealed. Meanwhile, farmers can't decide what seeds to plant, because seed and herbicide decisions are tightly linked. Time is short, though, because planting season has arrived."This not-knowing thing is concerning," says Mike Sullivan, a farmer in the town of Burdette. "It's embarrassing, is what it is.""Nobody knows what's going on," says Tom Burnham, another farmer located not far away in Blytheville. In late March, though, a different challenge to the dicamba ban, by a group of six farmers, produced a different decision. A judge dismissed the farmers' lawsuit, citing a ruling by the Arkansas Supreme Court that state agencies cannot be sued — yet the judge also gave the farmers exactly what they wanted. He lifted the ban on those six farmers because, he decided, they had been denied a legal avenue to appeal that ban. That ruling applied only to the six farmers who'd sued. But other farmers immediately seized the opportunity to file similar lawsuits in other counties. According to press reports, 155 farmers have joined similar lawsuits, and judges in Mississippi County and Phillips County have issued temporary injunctions that allow those farmers to spray dicamba.The state government is fighting back, appealing these decisions to the Arkansas Supreme Court.
