(Distributed 09/05/08) Rice is among the many Louisiana agricultural commodities hurt by Hurricane Gustav, although the majority of the crop had been harvested in the southwest Louisiana rice belt before the storm came through.

(Distributed 09/09/08) WHITEVILLE – Farmer Jeffrey Sylvester gazed over a field that looked more suited for water-skiing than growing rice. “There’s a rice crop under that water,” he said. “That’s all standing rice.”
