What steps does DuPont take to minimize adventitious presence in seed products?
DuPont invests significant time and resources to maintain the highest possible level of seed variety purity so that our customers will enjoy the full genetic potential of a specific variety, whether we developed it with conventional breeding or biotechnology. During seed production and harvesting, we meet or exceed the requirements of international, national and state regulatory authorities by using many strategies to prevent cross-pollination and seed mixing such as using required isolation distances between fields; planting border rows of a different variety that is not harvested for seed; staggering the planting dates of adjacent fields so that pollen shedding and receptivity are not in sync; and carefully cleaning the planting, harvesting, storage and conditioning equipment after each use. In addition, field inspectors monitor seed field operations to help ensure purity. Finally, we have a state-of-the-art genetic purity testing program and a detailed product identification and tra
