WILMINGTON, Del., November 9, 2006 - In a briefing today with investment analysts, DuPont said its subsidiary Pioneer Hi-Bred International, Inc. is seeing strong product performance from its seed products from this year’s harvest in North America and continues to grow in Brazil despite a difficult agricultural economy in that country. “With the results in on almost 20,000 field tests, Pioneer corn is averaging 6 bushels per acre more than competitors’ products, a 50 percent increase in the Pioneer corn yield advantage over last year,” said William S. Niebur , vice president -- DuPont Crop Genetics Research & Development. “We are especially excited about the performance we are seeing from our newer corn products.”
