There are no U.S. grade standards for Kudzu. These instructions have been developed by the Specialty Crops Inspection Division to assist officially licensed inspectors in making inspections, writing certificates and to assist in the proper identification of specialty type fruits and vegetables.
Kudzu (Yaka, Magnagna, Fankot) The kudzu root resembles the sweet potato somewhat, but has very coarse, tough skin. Some roots will grow to great size, but only the smaller roots are used commercially. The plant is a hairy, twining perennial which grows 30 to 60 feet long. Commercial use has slowed somewhat, being replaced by the sweet potato, but it is still grown for its starch content. It is native to China and Japan.
