American Cyanamid Company, AgriPro Seeds, Inc., and United Grain Growers Limited, today announced they have signed a research and development agreement to provide farmers with new
herbicide tolerant varieties of wheat, the single largest agricultural commodity globally.

"Many growers face limited yield and profit potential because they lack a reliable and effective method to control competitive weeds in wheat," says Scott Gaddis, Cyanamid's business director for imidazolinone tolerant crops. "We're committed to providing farmers with new innovative ways of maximizing their profitability. This agreement puts us closer to that goal."

Since the first imidazolinone tolerant crop was launched in 1992, thousands of growers have taken advantage of the benefits of this technology -- broad spectrum, season long, weed control that helps growers maximize yield and can eliminate the need for tank mixing or repeat applications. As a result of this agreement, these same opportunities will soon be available for wheat.

"UGG continues to establish close relationships with the best seed breeding programs and innovative partners in crop protection products from across the world," says Louie Sawatzky, UGG's managing director of Crop Production Services. "For the past ten years, AgriPro has worked with UGG to add real value by bringing superior wheat genetics to our customers' fields.
The introduction of imidazolinone tolerant wheat would be an exciting development for this program," he adds.

"AgriPro strives to provide wheat growers with the most advanced genetics and technologies available," explains Rob Bruns, Manager of Product Development for AgriPro Wheat. "Through this agreement with Cyanamid and UGG, we can offer growers the opportunity to further increase the value of their crop by combining superior weed control with high-quality, high-yielding
performance."

The imidazolinones are a unique family of crop protection products for weed control that were developed by Cyanamid Agricultural Products Research Division. The imidazolinones work on an enzyme which is present in plants but not in animals, birds, fish or insects.

The Cyanamid/AgriPro/UGG agreement is one of the most recent efforts by Cyanamid and collaborators to develop and market herbicide tolerant crops. Cyanamid was the first to market a herbicide tolerant crop with the release of imidazolinone tolerant corn in 1992, followed by imidazolinone canola, known as SMART(TM) canola, in Canada in 1995.

United Grain Growers is one of western Canada's largest agribusiness firms. Founded in 1906, the Winnipeg based company is diversified into grain merchandising, crop input sales and distribution, livestock production services and farm business communications. Proven Seed, a business unit of UGG, markets seed and plays an important role in bringing new genetic technology to western Canadian growers. UGG is publicly traded on the Toronto Stock Exchange and Winnipeg Stock Exchange, under the symbol "UGG."
