CALLISTO(R) Herbicide Named 2003 Product of the Year



Basel, Switzerland, August 29, 2003

CALLISTO(R), Syngenta's recently introduced blockbuster herbicide for corn, has
been named Product of the Year by Agri Marketing, a USA agribusiness magazine.

The Product of the Year Award program was created by the magazine to recognize
one agricultural product each year for outstanding marketing and impact in the
marketplace.

"We look for ag products or services that are generating excitement today and
will undoubtedly stand the test of time to be long recognized as major
contributors to the ag industry," said Bill Schuermann, senior vice president,
publisher and editorial director with Agri Marketing magazine.

Registered in the USA as a reduced-risk product in June 2001, CALLISTO(R) has
quickly become the leading post-emergent broadleaf herbicide in corn, used on
more than 4 million hectares of corn since its introduction.

CALLISTO(R) was originally inspired by the natural herbicides exuded by the
Callistemon citrinus plant. It provides a new mode of action for broadleaf weed
control, including those resistant or tolerant to glyphosate and certain other
herbicides. It provides growers with unprecedented post-emergent control of more
than 40 broadleaf weeds and offers unmatched crop safety along with a favorable
environmental profile.

LUMAXTM and CAMIXTM, two new pre-emergent herbicide mixtures - part of the
CALLISTO(R) - family, were recently launched in the USA corn market.

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
