Golden Valley, Minn. - August 23, 2007 - Syngenta announced today that it has obtained full regulatory approval in Japan for Agrisure® RW, its corn rootworm insect control corn seed. Agrisure RW now has full approval in the United States, Canada, and Japan, and import approval in Australia and New Zealand.

Syngenta’s innovation in genetics and traits such as Agrisure RW is helping growers meet the rapidly expanding demand for corn. The Agrisure brand spans a wide range of products bringing new choices to growers including Agrisure CB/LL, Agrisure GT, Agrisure RW, Agrisure GT/RW, Agrisure GT/CB/LL, Agrisure CB/LL/RW and Agrisure 3000GT.

In this introductory year, Agrisure RW growers participated in a comprehensive stewardship program to ensure their grain would remain in domestic markets. With this approval, Agrisure RW grain can now be accepted by elevators exporting grain to Japan. However, Syngenta is committed to and will continue to implement the grain stewardship program with growers through the end of 2007.

Golden Valley, Minn. - August 13, 2007 - For 2008, NK is expanding its already diverse portfolio to include 23 new soybeans, all selected from extensive research at more than 800,000 soybean plots at eight Syngenta research centers throughout the United States.

“This powerful soybean lineup provides growers with a broad range of options for the toughest disease, pest and weed issues that maximize yield performance in your fields,” says Jamie Leifker, NK marketing manager with Syngenta Seeds.

The new additions include six salt excluder soybeans, which limit distribution of chloride to vital plant parts, improving performance in salty fields. Plus, six of the new soybeans have been designated Extra Edge(tm) High Protein soybeans, and five are Extra Edge High Oil soybeans. The Extra Edge soybean portfolio characterizes products that offer high levels of oil or protein, and meet recommendations from the United Soybean Board, which encourages growers to choose soybeans that fit processor needs.

“By starting with the superior genetics of NK® Brand soybeans and adding Syngenta insect, disease and weed management options, growers have access to real productivity solutions that deliver higher yield and more profit,” Leifker says. “Plus, NK provides bulk options for increased efficiency, including the industry-leading TruBulk® soybean seed delivery system.”
