Potato growers in Idaho and eastern Oregon are scheduled to vote in March on whether to continue their federal marketing order.

Growers in Idaho and Malheur County, Ore., will vote by mail March 5-18 on the future of the order, according to the U.S. Department of Agriculture.

The potato marketing order requires a referendum every six years to continue, according to a news release from the USDA. To be eligible to vote, growers must have produced Irish potatoes within the production area between Aug. 1, 2009 and July 31, 2010, according to the release.

For the marketing order to continue, it must be approved by at least two-thirds of the growers voting, or by growers accounting for two-thirds of the volume of potatoes represented in the election.

The USDA Agricultural Marketing Service said it will mail ballots to growers of record before the voting period. However, the agency said growers who fail to receive ballots can request them from Barry Broadbent: AMS, USDA, 805 S.W. Broadway, Suite 930, Portland, OR 97205; by calling (503) 326-2724; or faxing (503) 326-7440.
