EDEN Bioscience Corporation (Nasdaq:EDEN), which develops, manufactures and markets innovative, natural products for protecting plants and improving crop production, today announced that it has received temporary registration from the Ministry of Agriculture in the Peoples Republic of China for the use of Messenger(R) on tomatoes and peppers.

"We are very excited about Messenger's performance in China on many of the same crops that we address in the U.S.," commented Jerry Butler, President and Chief Executive Officer. "China represents a new market for us, and we have strong support from its university agricultural community for the use of Messenger. We anticipate additional approvals in China on canola, cotton, rice, tobacco, and citrus this year and next."

EDEN Bioscience(R) has conducted over 100 field trials in conjunction with researchers at Nanjing Agricultural University. This registration is valid through September 29, 2002. EDEN expects to receive final registration upon completion of this standard one-year period.

EDEN Bioscience is a plant technology company focused on developing, manufacturing and marketing innovative natural products for agriculture. EDEN believes its technology and initial product, Messenger, allow it to offer superior alternatives to existing plant protection and crop yield enhancement products in terms of both performance and safety and, importantly, to avoid the substantial public resistance to many chemical pesticides and genetically modified plants. Messenger, which received EPA approval for full commercial use in April 2000, is based on naturally occurring proteins called "harpins," which activate natural plant defense systems to
protect against disease and pests, and simultaneously activate plant growth systems, improving crop yield and quality. It has been extensively tested in hundreds of field trials in four countries and on more than 40 crops including: citrus, cotton, strawberries, tomatoes, peppers, melons, wheat, rice, corn, peanuts, tobacco, grapes and others. EDEN Bioscience's headquarters are at 3830 Monte Villa Parkway, Bothell, WA 98021, (425) 806-7300; www.edenbio.com
