Potatoes (Solanum tuberosum) are grown for commercial and home garden production in North Carolina. Most of the commercial potato production acreage (~20,000 acres) is located in eastern North Carolina. Approximately 80% of the commercial potato crop is sold and processed into potato chips, while the remainder of the crop is sold as fresh market (table stock) potatoes for boiling and baking. Potatoes provide an added source of income to farmers in rural, eastern North Carolina and are often grown in rotation with lower economic value field crops such as corn, sorghum, soybean and wheat. Diseases, insects, unbalanced soil fertility, poor stand establishment and weeds continue to influence the production of healthy potato crops in North Carolina.
