Growing quality seed potatoes means growing disease free potatoes. To accomplish this, many states have established regulatory programs, we are certified by the Wisconsin Seed Potato Program. The state program includes multiple on-farm inspections during the growing season, and a winter grow out in Florida. This level of inspection ensures that you receive high quality, disease free seed. Seed that is not monitored/State Certified will have an unknown level of disease. Disease in the seed results in a reduction of plant vigor and yield, disease spread to healthy plants, and potentially the introduction of pathogens into your soils. The lengthy inspection process covers leaf roll, mosaics, spindle tuber, bacterial ring rot, blackleg, rhizoctonia, verticillium, mycoplasmas, white mold, early blight, late blight, variety mixture, growth and vigor, insect control, weed control, isolation and stand.
