Clean Plant Center of the Northwest

The Clean Plant Center Northwest (CPCNW) is a collaborative effort of scientists, researchers, nurseries and growers. We work together to increase the economic sustainability of specialty crop production in the United States.

The program emphasizes the management of diseases caused by viruses and virus-like agents that affect vegetatively propagated perennial plants including fruit trees, grapevines and hop plants.

  • Viruses cause smaller yields and lower quality fruits, nuts and vegetables

  • Viruses drain growers of time and money

  • Viruses mean fewer choices in the produce aisle for consumers

CPCNW is based at Washington State University’s Irrigated Agriculture Research and Extension Center (WSU-IAREC) in Prosser, Washington.

At the CPCNW, we offer clean plant services for fruit trees, grapes and hops. We have several different methods of diagnosing a wide range of virus and virus-like diseases. Our research strives to find better, faster and cheaper ways to test for viruses, and better ways to mange virus diseases once they appear. Our facilities provide places to diagnose, clean and store virus-tested trees and plants. Each team member brings a unique set of skills and experiences to CPCNW.

A major component of our effort is to work with Clean Plant Centers around the U.S. to keep agriculture growing strong by providing commercial agriculture with healthy virus-tested planting material.
