ENVOKE(R) herbicide gains registration in USA



Basel, Switzerland, October 1, 2003

Syngenta announced today that its herbicide ENVOKE(R) has received registration
from the U.S. Environmental Protection Agency. ENVOKE(R) controls a wide
spectrum of broadleaf weeds and grasses in cotton, sugarcane and tomatoes.

The active ingredient in ENVOKE(R), trifloxysulfuron sodium, controls these
weeds at an extremely low use rate. Extensive testing indicates that
applications made to cotton at the five-leaf stage and later are optimum in both
conventional and herbicide-tolerant varieties.

"ENVOKE is a much-needed answer to many of the major weeds that have troubled
cotton growers for years," said Mike Mack, President of Syngenta Crop
Protection, NAFTA. "Because of its broad-spectrum weed control and flexibility,
ENVOKE provides outstanding performance in both herbicide-tolerant and
conventional systems for weeds that are difficult to control."

ENVOKE(R) was first registered for use in Argentina in 2001 and is also used in
a number of other countries including Brazil and Australia.

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
2002 were approximately US $6.2 billion. Syngenta employs some 20,000 people in
over 90 countries. Syngenta is listed on the Swiss stock exchange (SYNN) and in
London (SYA), New York (SYT) and Stockholm (SYN). Further information is
