Tammy Sellmeyer bends to pick up a strawberry in the middle of a hoop house on the 25-acre farm she owns and operates with her husband, Greg, just south of Fulton, Mo. The Sellmeyers plant some 3,000 strawberry plants here each year and sell them at the Columbia, Mo. farmers market. This past May, they sold 400 quarts in just three hours. But two years ago, they didn't have many berries to sell at all because pests got to their crop.
