The Blueberry Extension Program is led by Dr. Wei Qiang Yang, district berry extension agent serving the North Willamette Valley. Our work is focused on commercial berry crops and in particular blueberry production. We specialize in all aspects of blueberry production systems from field establishment, physiology and nutrition, irrigation, disease and pest management to postharvest handling and international marketing. Our current projects include machine harvest for the fresh market, understanding crown gall infection, food safety and development of the blueberry tree.
