DuPont Achieves Regulatory Milestone for Agriculture Innovations

Wilmington, Del., Jan. 20, 2010 – DuPont announced it has applied to regulatory authorities in the European Union (EU) (represented by the U.K.), Canada and the United States for registration of two new crop protection disease control products. These countries will conduct a joint review as part of an Organization for Economic Cooperation and Development (OECD) Work Share project for regulatory harmonization. The two new fungicides, DuPont™ Fontelis™ and DuPont™ Vertisan™ will provide growers with preventative and curative disease control for a wide range of grain, fruit and vegetable crops.

“We look forward to providing these new tools to growers looking to maximize yield and quality with innovative answers to disease control issues,” said James C. Collins, president – DuPont Crop Protection. “These new products are another example of how DuPont Crop Protection is using market-driven science to help growers meet the global demand for increased food production.”

Submitting the regulatory package for the fungicides is a key milestone for DuPont. The company anticipates launching the new fungicides as early as 2011. DuPont also plans to develop additional products based on the active ingredient — penthiopyrad. Each of the new products will provide unique advantages to growers.

DuPont™ Fontelis™ fungicide will provide broad-spectrum control of diseases that threaten crop quality, yield and profitability in vegetables such as tomatoes and cucumbers, fruits such as apples, and peanuts.

DuPont™ Vertisan™ fungicide will provide broad-spectrum disease control in row crops such as wheat, barley and soybean. It is effective against a broad range of damaging plant diseases, including some diseases which have developed resistance to other fungicide chemistry classes.
