Syngenta presents new fungicide at British Crop Protection Congress

Basel, Switzerland, 31 October 2005

Today at the 2005 British Crop Protection Congress (BCPC), Syngenta presented its new fungicide active ingredient to agricultural experts. Mandipropamid, developed under the code 446, controls late blight in potatoes and tomatoes as well as downy mildew in vines and a number of vegetable crops.

Mandipropamid, the first derivative of the chemical class of mandelamide fungicides, sets a new standard in performance: locking rapidly and tightly to the leaf’s waxy layer, it provides a highly effective, weatherproof and long-lasting barrier to diseases.

“Mandipropamid is a significant innovation. This new technology further strengthens our leading fungicide portfolio, which offers growers a complete range of solutions to control plant disease” said John Atkin, Chief Operating Officer, Syngenta Crop Protection. “Mandipropamid is one of eight new crop protection products planned for launch by 2012.”

Mandipropamid is scheduled for launch in 2007 and will be offered as single formulation as well as in spray programs with other Syngenta brands, including Ridomil Gold®, Shirlan®, Quadris Max® and Bravo®. This new compound will be marketed globally and peak sales are expected to exceed $100 million annually.

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 2004 were approximately $7.3 billion. Syngenta employs some 20,000 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.
