DuPont today updates investors on DuPont Agriculture & Nutrition progress since its September 14 presentation on the growth strategy and pipeline for its seed, crop protection and soy ingredient businesses that generated $6.2 billion in revenue in 2004.

The company continues to see strong, balanced growth from Agriculture & Nutrition in Brazil.  Excellent product performance is driving Pioneer Hi-Bred International seed sales growth of more than 40 percent over 2004 despite difficult economic conditions in the region.  Introductory sales of biotech soybean varieties are positioning the company for further growth in that market in 2006.  Crop Protection sales in Brazil are up 7 percent with strong performance, notably in the sugarcane market.

The Agriculture & Nutrition sales and earnings outlook for the fourth quarter and full year is unchanged. The segment is on track for 2005 earnings growth in the high-teens for its fourth consecutive year.

Agriculture & Nutrition recently achieved a number of key successes in bringing its pipeline to the market:

• Herculex® RW Rootworm Protection and Herculex® XTRA, which contains both the Herculex® I Insect Protection and Herculex® RW Rootworm Protection traits, now have full U.S. regulatory approval .  The approvals allow Pioneer to sell corn hybrids with these traits in the U.S. for 2006 planting.
  
  Herculex® XTRA guards against a broader range of insects than other competitive products now available to growers.  The corn rootworm trait provides excellent root protection and dramatically reduces adult rootworm emergence.  Furthermore, early harvest results indicate Herculex® RW and Herculex® XTRA achieved 16-19 bushels yield advantage compared with corn protected with insecticides in drought-stressed locations.
  
  
• Herculex® I Insect Protection received approval for import and processing for feed use from the EU Commission.  Meaningful imports to the EU of grain from hybrids with the Herculex® I trait will begin to occur only after it also has been approved in the EU for "food" use, which is expected in early 2006.  Herculex® I has already been approved in 12 other countries around the world.
  
  
• Since September, DuPont Crop Protection has been granted U.S. registrations for two new herbicide blends:  DuPont™ Affinity™ BroadSpec herbicide for the control of tough broadleaf weeds in wheat and barley, and Velpar™ K4, a broad spectrum herbicide for sugarcane production.   Year to date, Crop Protection has received U.S. registrations for six new herbicide blends. All are based on patented, proprietary blend technology.
