Successful launch of LUMAXTM: new product in CALLISTO(R) family

Basel, Switzerland, August 6, 2003

Syngenta announced today that its newly launched corn herbicide LUMAXTM, part of
the CALLISTO(R) range, has been successfully introduced in the US market. LUMAX
TM, has been used on more than 2.5 million acres in its first season.  This
premium product is for use in the most intensive, high yielding regions of the
corn belt, providing the early weed control necessary for high yield in a single
application.

"I've been searching for a product that will control our weed problems with one
spraying," said Nick Adams, a 4,000-acre grower in Iowa. "LUMAXTM has proved to
me that it can get the job done."

LUMAXTM was registered for use on corn in the USA in late 2002.  It combines the
superior performance of CALLISTO(R) with two other Syngenta active ingredients.
Syngenta plans to extend market development of LUMAXTM into other key corn
producing countries in 2004-6.

The CALLISTO(R) family offers excellent weed control at low use rates,
outstanding crop safety and proven yield benefits.  CALLISTO(R), first launched
in the USA in mid 2001, has set a new standard in broad leaf weed control and is
the fastest growing herbicide in corn. Global sales of the CALLISTO(R) range
grew strongly in the first half of 2003 to almost US$ 200 million
