Arkansas rice growers will be banned in 2007 from planting the Cheniere variety, a seed rice that has tested positive for a genetically modified rice that contaminated some long-grain supplies this year. The decision Wednesday by the state Plant Board came as farmers are making decisions about planting for next year. "We need to act as quickly as possible, because producers are making business decisions right now," Plant Board Director Darryl Little said at the meeting in Little Rock.
