In a continuing effort to purge GM traits from the rice industry, the Arkansas State Plant Board has banned the rice variety Clearfield 131. The measure passed on a 6-5 vote at a March 2 emergency meeting and came after lengthy board deliberation and often emotional testimony from farmers, seedsmen and millers. Bred to harness a natural mutation to tolerate the Newpath herbicide, Clearfield varieties have provided growers new tools to fight yield-sapping red rice. Many farmers facing red rice infestations consider the Clearfield technology a godsend and have set up farms around it.
