Syngenta extends China manufacturing facility to support Asia growth

Basel, Switzerland, 28 February 2006

Syngenta today opened a technology center and broke ground for an additional production plant at its Gramoxone® facility in Nantong, Province of Jiangsu, PRC.

The new technology center in China has been established to provide technical support for additional local production and global sourcing. The 1600 square meter facility has four advanced laboratories for analysis and process development.

On the same site, the company also broke ground for a new manufacturing facility to meet growing demand for its modern insecticide portfolio. This is expected to become operational by mid 2007.

Participating in the opening ceremony, John Atkin, COO, Syngenta Crop Protection said: “These latest two projects at our Nantong site will significantly expand our capability to manufacture cost-competitive products that meet the highest standards. They will further strengthen our position in the growing Asian market”.

The Syngenta Nantong site was established in 1998 and is one of the largest agrochemical facilities in China. Since its opening in 2001, the site was granted numerous awards for safety, environmental performance and technology.

Syngenta is a world-leading agribusiness committed to sustainable agriculture through innovative research and technology. The company is a leader in crop protection, and ranks third in the high-value commercial seeds market. Sales in 2005 were approximately $8.1 billion. Syngenta employs more than 19,000 people in over 90 countries. Syngenta is listed on the Swiss stock exchange (SYNN) and in New York (SYT). Further information is available at www.syngenta.com.
